-<h1>Dockerfile Changelog<a class="headerlink" href="#dockerfile-changelog" title="Permalink to this headline">¶</a></h1>
-<p>The <code class="docutils literal notranslate"><span class="pre">Dockerfile</span></code> does not strictly follow the <a class="reference external" href="https://semver.org/">SemVer</a> approach of
-Apache Airflow when it comes to features and backwards compatibility. While Airflow code strictly
-follows it, the <code class="docutils literal notranslate"><span class="pre">Dockerfile</span></code> is really a way to give users a conveniently packaged Airflow
-using standard container approach, so occasionally there are some changes in the building process
-or in the entrypoint of the image that require slight adaptation of how it is used or built.</p>
-<p>The Changelog below describes the changes introduced in each version of the docker images released by
-the Airflow team.</p>
-<dl class="field-list simple">
-<dt class="field-odd">note</dt>
-<dd class="field-odd"><p>The Changelog below concerns only the convenience production images released at
-<a class="reference external" href="https://hub.docker.com/r/apache/airflow">Airflow DockerHub</a> . The images that are released
-there, are usually built using the <code class="docutils literal notranslate"><span class="pre">Dockerfile</span></code> released together with Airflow. However You are
-free to take latest released <code class="docutils literal notranslate"><span class="pre">Dockerfile</span></code> from Airflow and use it to build an image for
-any Airflow version from the <code class="docutils literal notranslate"><span class="pre">Airflow</span> <span class="pre">2</span></code> line. There is no guarantee that it works, but if it does,
-then you can use latest features from that image to build the previous Airflow versions.</p>

-<dt class="field-even">warning</dt>
-<dd class="field-even"><p>Some of the images below (as noted in the Changelog) have been regenerated using newer
-<code class="docutils literal notranslate"><span class="pre">Dockerfiles</span></code>. This happens when there is a breaking change that invalidates already released images
-and the images need regeneration. This has happened already when MySQL changed the keys they
-used to release their packages: <a class="reference external" href="https://github.com/apache/airflow/issues/20911">#20911</a>
-and 2.1 images were all regenerated using the 2.2 <code class="docutils literal notranslate"><span class="pre">Dockerfile</span></code>. This is a rare event and
-we do it only when we have no choice because of external factors. In such case, the newer version of
-the image <strong>might</strong> contain breaking changes when it comes to running or building the image (but
-we try to avoid those).</p>

-<p>If you are using the default entrypoint of the production image,
-there are a few actions that are automatically performed when the container starts.
-In some cases, you can pass environment variables to the image to trigger some of that behaviour.</p>
-<p>The variables that control the “execution” behaviour start with <code class="docutils literal notranslate"><span class="pre">_AIRFLOW</span></code> to distinguish them
-from the variables used to build the image starting with <code class="docutils literal notranslate"><span class="pre">AIRFLOW</span></code>.</p>

-<p>Airflow image is Open-Shift compatible, which means that you can start it with random user ID and the
-group id <code class="docutils literal notranslate"><span class="pre">0</span></code> (<code class="docutils literal notranslate"><span class="pre">root</span></code>). If you want to run the image with user different than Airflow, you MUST set
-GID of the user to <code class="docutils literal notranslate"><span class="pre">0</span></code>. In case you try to use different group, the entrypoint exits with error.</p>
-<p>OpenShift randomly assigns UID when it starts the container, but you can utilise this flexible UID
-also in case of running the image manually. This might be useful for example in case you want to
-mount <code class="docutils literal notranslate"><span class="pre">dag</span></code> and <code class="docutils literal notranslate"><span class="pre">logs</span></code> folders from host system on Linux, in which case the UID should be set
-the same ID as your host user.</p>
-<p>This can be achieved in various ways - you can change USER when you extend or customize the image or
-you can dynamically pass the user to <code class="docutils literal notranslate"><span class="pre">docker</span> <span class="pre">run</span></code> command, by adding <code class="docutils literal notranslate"><span class="pre">--user</span></code> flag in one of
-those formats (See <a class="reference external" href="https://docs.docker.com/engine/reference/run/#user">Docker Run reference</a> for details):</p>

-<span class="pre">`</span></code></p>
-<p>In case of Docker Compose environment it can be changed via <code class="docutils literal notranslate"><span class="pre">user:</span></code> entry in the <code class="docutils literal notranslate"><span class="pre">docker-compose.yaml</span></code>.
-See <a class="reference external" href="https://docs.docker.com/compose/compose-file/compose-file-v3/#domainname-hostname-ipc-mac_address-privileged-read_only-shm_size-stdin_open-tty-user-working_dir">Docker compose reference</a>
-for details. In our Quickstart Guide using Docker-Compose, the UID can be passed via the
-<code class="docutils literal notranslate"><span class="pre">AIRFLOW_UID</span></code> variable as described in
-<a class="reference external" href="/docs/apache-airflow/stable/start/docker.html#initializing-docker-compose-environment" title="(in apache-airflow v2.4.0.dev0)"><span class="xref std std-ref">Initializing docker compose environment</span></a>.</p>
-<p>The user can be any UID. In case UID is different than the default
-<code class="docutils literal notranslate"><span class="pre">airflow</span></code> (UID=50000), the user will be automatically created when entering the container.</p>
-<p>In order to accommodate a number of external libraries and projects, Airflow will automatically create
-such an arbitrary user in (<cite>/etc/passwd</cite>) and make it’s home directory point to <code class="docutils literal notranslate"><span class="pre">/home/airflow</span></code>.
-Many of 3rd-party libraries and packages require home directory of the user to be present, because they
-need to write some cache information there, so such a dynamic creation of a user is necessary.</p>
-<p>Such arbitrary user has to be able to write to certain directories that needs write access, and since
-it is not advised to allow write access to “other” for security reasons, the OpenShift
-guidelines introduced the concept of making all such folders have the <code class="docutils literal notranslate"><span class="pre">0</span></code> (<code class="docutils literal notranslate"><span class="pre">root</span></code>) group id (GID).
-All the directories that need write access in the Airflow production image have GID set to 0 (and
-they are writable for the group). We are following that concept and all the directories that need
-write access follow that.</p>
-<p>The GID=0 is set as default for the <code class="docutils literal notranslate"><span class="pre">airflow</span></code> user, so any directories it creates have GID set to 0
-by default. The entrypoint sets <code class="docutils literal notranslate"><span class="pre">umask</span></code> to be <code class="docutils literal notranslate"><span class="pre">0002</span></code> - this means that any directories created by
-the user have also “group write” access for group <code class="docutils literal notranslate"><span class="pre">0</span></code> - they will be writable by other users with
-<code class="docutils literal notranslate"><span class="pre">root</span></code> group. Also whenever any “arbitrary” user creates a folder (for example in a mounted volume), that
-folder will have a “group write” access and <code class="docutils literal notranslate"><span class="pre">GID=0</span></code>, so that execution with another, arbitrary user
-will still continue to work, even if such directory is mounted by another arbitrary user later.</p>
-<p>The <code class="docutils literal notranslate"><span class="pre">umask</span></code> setting however only works for runtime of the container - it is not used during building of

-<p class="admonition-title">Warning</p>
-<p>Installing requirements this way is a very convenient method of running Airflow, very useful for
-testing and debugging. However, do not be tricked by its convenience. You should never, ever use it in
-production environment. We have deliberately chose to make it a development/test dependency and we print
-a warning, whenever it is used. There is an inherent security-related issue with using this method in
-production. Installing the requirements this way can happen at literally any time - when your containers
-get restarted, when your machines in K8S cluster get restarted. In a K8S Cluster those events can happen
-literally any time. This opens you up to a serious vulnerability where your production environment
-might be brought down by a single dependency being removed from PyPI - or even dependency of your
-dependency. This means that you put your production service availability in hands of 3rd-party developers.
-At any time, any moment including weekends and holidays those 3rd party developers might bring your
-production Airflow instance down, without you even knowing it. This is a serious vulnerability that
-is similar to the infamous
-<a class="reference external" href="https://qz.com/646467/how-one-programmer-broke-the-internet-by-deleting-a-tiny-piece-of-code/">leftpad</a>
-problem. You can fully protect against this case by building your own, immutable custom image, where the
-dependencies are baked in. You have been warned.</p>
-</div>
-<p>Installing additional requirements can be done by specifying <code class="docutils literal notranslate"><span class="pre">_PIP_ADDITIONAL_REQUIREMENTS</span></code> variable.
-The variable should contain a list of requirements that should be installed additionally when entering
-the containers. Note that this option slows down starting of Airflow as every time any container starts
-it must install new packages and it opens up huge potential security vulnerability when used in production
-(see below). Therefore this option should only be used for testing. When testing is finished,
-you should create your custom image with dependencies baked in.</p>

-<div class="highlight-bash notranslate"><div class="highlight"><pre><span></span>docker run -it -p <span class="m">8080</span>:8080 <span class="se">\</span>

-<h1>Dockerfile Changelog<a class="headerlink" href="#dockerfile-changelog" title="Permalink to this headline">¶</a></h1>
-<p>The <code class="docutils literal notranslate"><span class="pre">Dockerfile</span></code> does not strictly follow the <a class="reference external" href="https://semver.org/">SemVer</a> approach of
-Apache Airflow when it comes to features and backwards compatibility. While Airflow code strictly
-follows it, the <code class="docutils literal notranslate"><span class="pre">Dockerfile</span></code> is really a way to give users a conveniently packaged Airflow
-using standard container approach, so occasionally there are some changes in the building process
-or in the entrypoint of the image that require slight adaptation of how it is used or built.</p>
-<p>The Changelog below describes the changes introduced in each version of the docker images released by
-the Airflow team.</p>
-<dl class="field-list simple">
-<dt class="field-odd">note</dt>
-<dd class="field-odd"><p>The Changelog below concerns only the convenience production images released at
-<a class="reference external" href="https://hub.docker.com/r/apache/airflow">Airflow DockerHub</a> . The images that are released
-there, are usually built using the <code class="docutils literal notranslate"><span class="pre">Dockerfile</span></code> released together with Airflow. However You are
-free to take latest released <code class="docutils literal notranslate"><span class="pre">Dockerfile</span></code> from Airflow and use it to build an image for
-any Airflow version from the <code class="docutils literal notranslate"><span class="pre">Airflow</span> <span class="pre">2</span></code> line. There is no guarantee that it works, but if it does,
-then you can use latest features from that image to build the previous Airflow versions.</p>
-</dd>
-<dt class="field-even">warning</dt>
-<dd class="field-even"><p>Some of the images below (as noted in the Changelog) have been regenerated using newer
-<code class="docutils literal notranslate"><span class="pre">Dockerfiles</span></code>. This happens when there is a breaking change that invalidates already released images
-and the images need regeneration. This has happened already when MySQL changed the keys they
-used to release their packages: <a class="reference external" href="https://github.com/apache/airflow/issues/20911">#20911</a>
-and 2.1 images were all regenerated using the 2.2 <code class="docutils literal notranslate"><span class="pre">Dockerfile</span></code>. This is a rare event and
-we do it only when we have no choice because of external factors. In such case, the newer version of

-<h1>Dockerfile Changelog<a class="headerlink" href="#dockerfile-changelog" title="Permalink to this headline">¶</a></h1>
-<p>The <code class="docutils literal notranslate"><span class="pre">Dockerfile</span></code> does not strictly follow the <a class="reference external" href="https://semver.org/">SemVer</a> approach of
-Apache Airflow when it comes to features and backwards compatibility. While Airflow code strictly
-follows it, the <code class="docutils literal notranslate"><span class="pre">Dockerfile</span></code> is really a way to give users a conveniently packaged Airflow
-using standard container approach, so occasionally there are some changes in the building process
-or in the entrypoint of the image that require slight adaptation of how it is used or built.</p>
-<p>The Changelog below describes the changes introduced in each version of the docker images released by
-the Airflow team.</p>
-<dl class="field-list simple">
-<dt class="field-odd">note</dt>
-<dd class="field-odd"><p>The Changelog below concerns only the convenience production images released at
-<a class="reference external" href="https://hub.docker.com/r/apache/airflow">Airflow DockerHub</a> . The images that are released
-there, are usually built using the <code class="docutils literal notranslate"><span class="pre">Dockerfile</span></code> released together with Airflow. However You are
-free to take latest released <code class="docutils literal notranslate"><span class="pre">Dockerfile</span></code> from Airflow and use it to build an image for
-any Airflow version from the <code class="docutils literal notranslate"><span class="pre">Airflow</span> <span class="pre">2</span></code> line. There is no guarantee that it works, but if it does,
-then you can use latest features from that image to build the previous Airflow versions.</p>

-<dt class="field-even">warning</dt>
-<dd class="field-even"><p>Some of the images below (as noted in the Changelog) have been regenerated using newer
-<code class="docutils literal notranslate"><span class="pre">Dockerfiles</span></code>. This happens when there is a breaking change that invalidates already released images
-and the images need regeneration. This has happened already when MySQL changed the keys they
-used to release their packages: <a class="reference external" href="https://github.com/apache/airflow/issues/20911">#20911</a>
-and 2.1 images were all regenerated using the 2.2 <code class="docutils literal notranslate"><span class="pre">Dockerfile</span></code>. This is a rare event and
-we do it only when we have no choice because of external factors. In such case, the newer version of
-the image <strong>might</strong> contain breaking changes when it comes to running or building the image (but
-we try to avoid those).</p>

-<h1>Dockerfile Changelog<a class="headerlink" href="#dockerfile-changelog" title="Permalink to this headline">¶</a></h1>
-<p>The <code class="docutils literal notranslate"><span class="pre">Dockerfile</span></code> does not strictly follow the <a class="reference external" href="https://semver.org/">SemVer</a> approach of
-Apache Airflow when it comes to features and backwards compatibility. While Airflow code strictly
-follows it, the <code class="docutils literal notranslate"><span class="pre">Dockerfile</span></code> is really a way to give users a conveniently packaged Airflow
-using standard container approach, so occasionally there are some changes in the building process
-or in the entrypoint of the image that require slight adaptation of how it is used or built.</p>
-<p>The Changelog below describes the changes introduced in each version of the docker images released by
-the Airflow team.</p>
-<dl class="field-list simple">
-<dt class="field-odd">note</dt>
-<dd class="field-odd"><p>The Changelog below concerns only the convenience production images released at
-<a class="reference external" href="https://hub.docker.com/r/apache/airflow">Airflow DockerHub</a> . The images that are released
-there, are usually built using the <code class="docutils literal notranslate"><span class="pre">Dockerfile</span></code> released together with Airflow. However You are
-free to take latest released <code class="docutils literal notranslate"><span class="pre">Dockerfile</span></code> from Airflow and use it to build an image for
-any Airflow version from the <code class="docutils literal notranslate"><span class="pre">Airflow</span> <span class="pre">2</span></code> line. There is no guarantee that it works, but if it does,
-then you can use latest features from that image to build the previous Airflow versions.</p>

-<dt class="field-even">warning</dt>
-<dd class="field-even"><p>Some of the images below (as noted in the Changelog) have been regenerated using newer
-<code class="docutils literal notranslate"><span class="pre">Dockerfiles</span></code>. This happens when there is a breaking change that invalidates already released images
-and the images need regeneration. This has happened already when MySQL changed the keys they
-used to release their packages: <a class="reference external" href="https://github.com/apache/airflow/issues/20911">#20911</a>
-and 2.1 images were all regenerated using the 2.2 <code class="docutils literal notranslate"><span class="pre">Dockerfile</span></code>. This is a rare event and
-we do it only when we have no choice because of external factors. In such case, the newer version of
-the image <strong>might</strong> contain breaking changes when it comes to running or building the image (but
-we try to avoid those).</p>

-<h1>Dockerfile Changelog<a class="headerlink" href="#dockerfile-changelog" title="Permalink to this headline">¶</a></h1>
-<p>The <code class="docutils literal notranslate"><span class="pre">Dockerfile</span></code> does not strictly follow the <a class="reference external" href="https://semver.org/">SemVer</a> approach of
-Apache Airflow when it comes to features and backwards compatibility. While Airflow code strictly
-follows it, the <code class="docutils literal notranslate"><span class="pre">Dockerfile</span></code> is really a way to give users a conveniently packaged Airflow
-using standard container approach, so occasionally there are some changes in the building process
-or in the entrypoint of the image that require slight adaptation of how it is used or built.</p>
-<p>The Changelog below describes the changes introduced in each version of the docker images released by
-the Airflow team.</p>
-<dl class="field-list simple">
-<dt class="field-odd">note</dt>
-<dd class="field-odd"><p>The Changelog below concerns only the convenience production images released at
-<a class="reference external" href="https://hub.docker.com/r/apache/airflow">Airflow DockerHub</a> . The images that are released
-there, are usually built using the <code class="docutils literal notranslate"><span class="pre">Dockerfile</span></code> released together with Airflow. However You are
-free to take latest released <code class="docutils literal notranslate"><span class="pre">Dockerfile</span></code> from Airflow and use it to build an image for
-any Airflow version from the <code class="docutils literal notranslate"><span class="pre">Airflow</span> <span class="pre">2</span></code> line. There is no guarantee that it works, but if it does,
-then you can use latest features from that image to build the previous Airflow versions.</p>

-<dt class="field-even">warning</dt>
-<dd class="field-even"><p>Some of the images below (as noted in the Changelog) have been regenerated using newer
-<code class="docutils literal notranslate"><span class="pre">Dockerfiles</span></code>. This happens when there is a breaking change that invalidates already released images
-and the images need regeneration. This has happened already when MySQL changed the keys they
-used to release their packages: <a class="reference external" href="https://github.com/apache/airflow/issues/20911">#20911</a>
-and 2.1 images were all regenerated using the 2.2 <code class="docutils literal notranslate"><span class="pre">Dockerfile</span></code>. This is a rare event and
-we do it only when we have no choice because of external factors. In such case, the newer version of
-the image <strong>might</strong> contain breaking changes when it comes to running or building the image (but
-we try to avoid those).</p>

-This can be done by setting <code class="docutils literal notranslate"><span class="pre">DOCKER_BUILDKIT=1</span></code> as an environment variable

-<h1>Dockerfile Changelog<a class="headerlink" href="#dockerfile-changelog" title="Permalink to this headline">¶</a></h1>
-<p>The <code class="docutils literal notranslate"><span class="pre">Dockerfile</span></code> does not strictly follow the <a class="reference external" href="https://semver.org/">SemVer</a> approach of
-Apache Airflow when it comes to features and backwards compatibility. While Airflow code strictly
-follows it, the <code class="docutils literal notranslate"><span class="pre">Dockerfile</span></code> is really a way to give users a conveniently packaged Airflow
-using standard container approach, so occasionally there are some changes in the building process
-or in the entrypoint of the image that require slight adaptation of how it is used or built.</p>
-<p>The Changelog below describes the changes introduced in each version of the docker images released by
-the Airflow team.</p>
-<dl class="field-list simple">
-<dt class="field-odd">note</dt>
-<dd class="field-odd"><p>The Changelog below concerns only the convenience production images released at
-<a class="reference external" href="https://hub.docker.com/r/apache/airflow">Airflow DockerHub</a> . The images that are released
-there, are usually built using the <code class="docutils literal notranslate"><span class="pre">Dockerfile</span></code> released together with Airflow. However You are
-free to take latest released <code class="docutils literal notranslate"><span class="pre">Dockerfile</span></code> from Airflow and use it to build an image for
-any Airflow version from the <code class="docutils literal notranslate"><span class="pre">Airflow</span> <span class="pre">2</span></code> line. There is no guarantee that it works, but if it does,
-then you can use latest features from that image to build the previous Airflow versions.</p>

-<dt class="field-even">warning</dt>
-<dd class="field-even"><p>Some of the images below (as noted in the Changelog) have been regenerated using newer
-<code class="docutils literal notranslate"><span class="pre">Dockerfiles</span></code>. This happens when there is a breaking change that invalidates already released images
-and the images need regeneration. This has happened already when MySQL changed the keys they
-used to release their packages: <a class="reference external" href="https://github.com/apache/airflow/issues/20911">#20911</a>
-and 2.1 images were all regenerated using the 2.2 <code class="docutils literal notranslate"><span class="pre">Dockerfile</span></code>. This is a rare event and
-we do it only when we have no choice because of external factors. In such case, the newer version of
-the image <strong>might</strong> contain breaking changes when it comes to running or building the image (but
-we try to avoid those).</p>

-<h1>Dockerfile Changelog<a class="headerlink" href="#dockerfile-changelog" title="Permalink to this headline">¶</a></h1>
-<p>The <code class="docutils literal notranslate"><span class="pre">Dockerfile</span></code> does not strictly follow the <a class="reference external" href="https://semver.org/">SemVer</a> approach of
-Apache Airflow when it comes to features and backwards compatibility. While Airflow code strictly
-follows it, the <code class="docutils literal notranslate"><span class="pre">Dockerfile</span></code> is really a way to give users a conveniently packaged Airflow
-using standard container approach, so occasionally there are some changes in the building process
-or in the entrypoint of the image that require slight adaptation of how it is used or built.</p>
-<p>The Changelog below describes the changes introduced in each version of the docker images released by
-the Airflow team.</p>
-<dl class="field-list simple">
-<dt class="field-odd">note</dt>
-<dd class="field-odd"><p>The Changelog below concerns only the convenience production images released at
-<a class="reference external" href="https://hub.docker.com/r/apache/airflow">Airflow DockerHub</a> . The images that are released
-there, are usually built using the <code class="docutils literal notranslate"><span class="pre">Dockerfile</span></code> released together with Airflow. However You are
-free to take latest released <code class="docutils literal notranslate"><span class="pre">Dockerfile</span></code> from Airflow and use it to build an image for
-any Airflow version from the <code class="docutils literal notranslate"><span class="pre">Airflow</span> <span class="pre">2</span></code> line. There is no guarantee that it works, but if it does,
-then you can use latest features from that image to build the previous Airflow versions.</p>

-<dt class="field-even">warning</dt>
-<dd class="field-even"><p>Some of the images below (as noted in the Changelog) have been regenerated using newer
-<code class="docutils literal notranslate"><span class="pre">Dockerfiles</span></code>. This happens when there is a breaking change that invalidates already released images
-and the images need regeneration. This has happened already when MySQL changed the keys they
-used to release their packages: <a class="reference external" href="https://github.com/apache/airflow/issues/20911">#20911</a>
-and 2.1 images were all regenerated using the 2.2 <code class="docutils literal notranslate"><span class="pre">Dockerfile</span></code>. This is a rare event and
-we do it only when we have no choice because of external factors. In such case, the newer version of
-the image <strong>might</strong> contain breaking changes when it comes to running or building the image (but
-we try to avoid those).</p>

-<h1>Dockerfile Changelog<a class="headerlink" href="#dockerfile-changelog" title="Permalink to this headline">¶</a></h1>
-<p>The <code class="docutils literal notranslate"><span class="pre">Dockerfile</span></code> does not strictly follow the <a class="reference external" href="https://semver.org/">SemVer</a> approach of
-Apache Airflow when it comes to features and backwards compatibility. While Airflow code strictly
-follows it, the <code class="docutils literal notranslate"><span class="pre">Dockerfile</span></code> is really a way to give users a conveniently packaged Airflow
-using standard container approach, so occasionally there are some changes in the building process
-or in the entrypoint of the image that require slight adaptation of how it is used or built.</p>
-<p>The Changelog below describes the changes introduced in each version of the docker images released by
-the Airflow team.</p>
-<dl class="field-list simple">
-<dt class="field-odd">note</dt>
-<dd class="field-odd"><p>The Changelog below concerns only the convenience production images released at
-<a class="reference external" href="https://hub.docker.com/r/apache/airflow">Airflow DockerHub</a> . The images that are released
-there, are usually built using the <code class="docutils literal notranslate"><span class="pre">Dockerfile</span></code> released together with Airflow. However You are
-free to take latest released <code class="docutils literal notranslate"><span class="pre">Dockerfile</span></code> from Airflow and use it to build an image for
-any Airflow version from the <code class="docutils literal notranslate"><span class="pre">Airflow</span> <span class="pre">2</span></code> line. There is no guarantee that it works, but if it does,
-then you can use latest features from that image to build the previous Airflow versions.</p>

-<dt class="field-even">warning</dt>
-<dd class="field-even"><p>Some of the images below (as noted in the Changelog) have been regenerated using newer
-<code class="docutils literal notranslate"><span class="pre">Dockerfiles</span></code>. This happens when there is a breaking change that invalidates already released images
-and the images need regeneration. This has happened already when MySQL changed the keys they
-used to release their packages: <a class="reference external" href="https://github.com/apache/airflow/issues/20911">#20911</a>
-and 2.1 images were all regenerated using the 2.2 <code class="docutils literal notranslate"><span class="pre">Dockerfile</span></code>. This is a rare event and
-we do it only when we have no choice because of external factors. In such case, the newer version of
-the image <strong>might</strong> contain breaking changes when it comes to running or building the image (but
-we try to avoid those).</p>

-<h1>Dockerfile Changelog<a class="headerlink" href="#dockerfile-changelog" title="Permalink to this headline">¶</a></h1>
-<p>The <code class="docutils literal notranslate"><span class="pre">Dockerfile</span></code> does not strictly follow the <a class="reference external" href="https://semver.org/">SemVer</a> approach of
-Apache Airflow when it comes to features and backwards compatibility. While Airflow code strictly
-follows it, the <code class="docutils literal notranslate"><span class="pre">Dockerfile</span></code> is really a way to give users a conveniently packaged Airflow
-using standard container approach, so occasionally there are some changes in the building process
-or in the entrypoint of the image that require slight adaptation of how it is used or built.</p>
-<p>The Changelog below describes the changes introduced in each version of the docker images released by
-the Airflow team.</p>
-<dl class="field-list simple">
-<dt class="field-odd">note</dt>
-<dd class="field-odd"><p>The Changelog below concerns only the convenience production images released at
-<a class="reference external" href="https://hub.docker.com/r/apache/airflow">Airflow DockerHub</a> . The images that are released
-there, are usually built using the <code class="docutils literal notranslate"><span class="pre">Dockerfile</span></code> released together with Airflow. However You are
-free to take latest released <code class="docutils literal notranslate"><span class="pre">Dockerfile</span></code> from Airflow and use it to build an image for
-any Airflow version from the <code class="docutils literal notranslate"><span class="pre">Airflow</span> <span class="pre">2</span></code> line. There is no guarantee that it works, but if it does,
-then you can use latest features from that image to build the previous Airflow versions.</p>

-<dt class="field-even">warning</dt>
-<dd class="field-even"><p>Some of the images below (as noted in the Changelog) have been regenerated using newer
-<code class="docutils literal notranslate"><span class="pre">Dockerfiles</span></code>. This happens when there is a breaking change that invalidates already released images
-and the images need regeneration. This has happened already when MySQL changed the keys they
-used to release their packages: <a class="reference external" href="https://github.com/apache/airflow/issues/20911">#20911</a>
-and 2.1 images were all regenerated using the 2.2 <code class="docutils literal notranslate"><span class="pre">Dockerfile</span></code>. This is a rare event and
-we do it only when we have no choice because of external factors. In such case, the newer version of
-the image <strong>might</strong> contain breaking changes when it comes to running or building the image (but
-we try to avoid those).</p>

-<h1>Dockerfile Changelog<a class="headerlink" href="#dockerfile-changelog" title="Permalink to this headline">¶</a></h1>
-<p>The <code class="docutils literal notranslate"><span class="pre">Dockerfile</span></code> does not strictly follow the <a class="reference external" href="https://semver.org/">SemVer</a> approach of
-Apache Airflow when it comes to features and backwards compatibility. While Airflow code strictly
-follows it, the <code class="docutils literal notranslate"><span class="pre">Dockerfile</span></code> is really a way to give users a conveniently packaged Airflow
-using standard container approach, so occasionally there are some changes in the building process
-or in the entrypoint of the image that require slight adaptation of how it is used or built.</p>
-<p>The Changelog below describes the changes introduced in each version of the docker images released by
-the Airflow team.</p>
-<dl class="field-list simple">
-<dt class="field-odd">note</dt>
-<dd class="field-odd"><p>The Changelog below concerns only the convenience production images released at
-<a class="reference external" href="https://hub.docker.com/r/apache/airflow">Airflow DockerHub</a> . The images that are released
-there, are usually built using the <code class="docutils literal notranslate"><span class="pre">Dockerfile</span></code> released together with Airflow. However You are
-free to take latest released <code class="docutils literal notranslate"><span class="pre">Dockerfile</span></code> from Airflow and use it to build an image for
-any Airflow version from the <code class="docutils literal notranslate"><span class="pre">Airflow</span> <span class="pre">2</span></code> line. There is no guarantee that it works, but if it does,
-then you can use latest features from that image to build the previous Airflow versions.</p>

-<dd class="field-even"><p>Some of the images below (as noted in the Changelog) have been regenerated using newer
-<code class="docutils literal notranslate"><span class="pre">Dockerfiles</span></code>. This happens when there is a breaking change that invalidates already released images
-and the images need regeneration. This has happened already when MySQL changed the keys they
-used to release their packages: <a class="reference external" href="https://github.com/apache/airflow/issues/20911">#20911</a>
-and 2.1 images were all regenerated using the 2.2 <code class="docutils literal notranslate"><span class="pre">Dockerfile</span></code>. This is a rare event and
-we do it only when we have no choice because of external factors. In such case, the newer version of
-the image <strong>might</strong> contain breaking changes when it comes to running or building the image (but
-we try to avoid those).</p>

-there, are usually built using the <code class="docutils literal notranslate"><span class="pre">Dockerfile</span></code> released together with Airflow. However You are
-free to take latest released <code class="docutils literal notranslate"><span class="pre">Dockerfile</span></code> from Airflow and use it to build an image for
-any Airflow version from the <code class="docutils literal notranslate"><span class="pre">Airflow</span> <span class="pre">2</span></code> line. There is no guarantee that it works, but if it does,
-then you can use latest features from that image to build the previous Airflow versions.</p>

-<dt class="field-even">warning</dt>
-<dd class="field-even"><p>Some of the images below (as noted in the Changelog) have been regenerated using newer
-<code class="docutils literal notranslate"><span class="pre">Dockerfiles</span></code>. This happens when there is a breaking change that invalidates already released images
-and the images need regeneration. This has happened already when MySQL changed the keys they
-used to release their packages: <a class="reference external" href="https://github.com/apache/airflow/issues/20911">#20911</a>
-and 2.1 images were all regenerated using the 2.2 <code class="docutils literal notranslate"><span class="pre">Dockerfile</span></code>. This is a rare event and
-we do it only when we have no choice because of external factors. In such case, the newer version of
-the image <strong>might</strong> contain breaking changes when it comes to running or building the image (but
-we try to avoid those).</p>

-however requires <a class="reference external" href="https://docs.docker.com/develop/develop-images/build_enhancements/">Buildkit</a>
-to build the image because we started using features that are only available in <code class="docutils literal notranslate"><span class="pre">Buildkit</span></code>.
-This can be done by setting <code class="docutils literal notranslate"><span class="pre">DOCKER_BUILDKIT=1</span></code> as an environment variable
-or by installing <a class="reference external" href="https://docs.docker.com/buildx/working-with-buildx/">the buildx plugin</a>

-<h1>Dockerfile Changelog<a class="headerlink" href="#dockerfile-changelog" title="Permalink to this headline">¶</a></h1>
-<p>The <code class="docutils literal notranslate"><span class="pre">Dockerfile</span></code> does not strictly follow the <a class="reference external" href="https://semver.org/">SemVer</a> approach of
-Apache Airflow when it comes to features and backwards compatibility. While Airflow code strictly
-follows it, the <code class="docutils literal notranslate"><span class="pre">Dockerfile</span></code> is really a way to give users a conveniently packaged Airflow
-using standard container approach, so occasionally there are some changes in the building process
-or in the entrypoint of the image that require slight adaptation of how it is used or built.</p>
-<p>The Changelog below describes the changes introduced in each version of the docker images released by
-the Airflow team.</p>
-<dl class="field-list simple">
-<dt class="field-odd">note</dt>
-<dd class="field-odd"><p>The Changelog below concerns only the convenience production images released at
-<a class="reference external" href="https://hub.docker.com/r/apache/airflow">Airflow DockerHub</a> . The images that are released
-there, are usually built using the <code class="docutils literal notranslate"><span class="pre">Dockerfile</span></code> released together with Airflow. However You are
-free to take latest released <code class="docutils literal notranslate"><span class="pre">Dockerfile</span></code> from Airflow and use it to build an image for
-any Airflow version from the <code class="docutils literal notranslate"><span class="pre">Airflow</span> <span class="pre">2</span></code> line. There is no guarantee that it works, but if it does,
-then you can use latest features from that image to build the previous Airflow versions.</p>

-<dt class="field-even">warning</dt>
-<dd class="field-even"><p>Some of the images below (as noted in the Changelog) have been regenerated using newer
-<code class="docutils literal notranslate"><span class="pre">Dockerfiles</span></code>. This happens when there is a breaking change that invalidates already released images
-and the images need regeneration. This has happened already when MySQL changed the keys they
-used to release their packages: <a class="reference external" href="https://github.com/apache/airflow/issues/20911">#20911</a>
-and 2.1 images were all regenerated using the 2.2 <code class="docutils literal notranslate"><span class="pre">Dockerfile</span></code>. This is a rare event and
-we do it only when we have no choice because of external factors. In such case, the newer version of
-the image <strong>might</strong> contain breaking changes when it comes to running or building the image (but
-we try to avoid those).</p>

-<li><p>Airflow 2.3 <code class="docutils literal notranslate"><span class="pre">Dockerfile</span></code> is now better optimized for caching and “standalone” which means that you

-however requires <a class="reference external" href="https://docs.docker.com/develop/develop-images/build_enhancements/">Buildkit</a>
-to build the image because we started using features that are only available in <code class="docutils literal notranslate"><span class="pre">Buildkit</span></code>.
-This can be done by setting <code class="docutils literal notranslate"><span class="pre">DOCKER_BUILDKIT=1</span></code> as an environment variable
-or by installing <a class="reference external" href="https://docs.docker.com/buildx/working-with-buildx/">the buildx plugin</a>
