+
+Adding Connections, Variables and Environment Variables
+=======================================================
+
+You can programmatically add Connections, Variables and arbitrary Environment Variables to your
+Airflow deployment using the Helm chart.
+
+
+Connections and Sensitive Environment Variables
+-----------------------------------------------
+Under the ``secret`` and ``extraSecret`` sections of the ``values.yaml`` you can pass connection strings and sensitive
+environment variables into Airflow using the Helm chart. To illustrate, lets create a yaml file called ``override.yaml``
+to override values under these sections of the ``values.yaml`` file.
+
+.. code-block:: yaml
+
+ # override.yaml
+
+ secret:
+ - envName: "AIRFLOW_CONN_GCP"
+ secretName: "my-airflow-connections"
+ secretKey: "AIRFLOW_CONN_GCP"
+ - envName: "my-env"
+ secretName: "my-secret-name"
+ secretKey: "my-secret-key"
+
+ extraSecrets:
+ my-airflow-connections:
+ data: |
+ AIRFLOW_CONN_GCP: 'base64_encoded_gcp_conn_string'
+ my-secret-name:
+ stringData: |
+ my-secret-key: my-secret
+
+
+Variables
+---------
+Airflow supports Variables which enable users to craft dynamic DAGs. You can set Variables in Airflow in three ways - UI,
+command line, and within your DAG file. See :doc:`apache-airflow:howto/variable` for more.
+
+With the Helm chart, you can also inject environment variables into Airflow. So in the example ``override.yaml`` file,
+we can override values of interest in the ``env`` section of the ``values.yaml`` file.
+
+.. code-block:: yaml
+
+ env:
+ - name: "AIRFLOW_VAR_KEY"
+ value: "value_1"
+ - name: "AIRFLOW_VAR_ANOTHER_KEY"
+ value: "value_2"
+
+
+You can also utilize ``extraEnv`` and ``extraEnvFrom`` if you need the name or value to be templated.
+
+.. code-block:: yaml
+
+ extraEnv: |
+ - name: AIRFLOW_VAR_HELM_RELEASE_NAME
+ value: '{{ .Release.Name }}'
+
+ extraEnvFrom: |
+ - configMapRef:
+ name: '{{ .Release.Name }}-airflow-variables'
+
+ extraConfigMaps:
+ '{{ .Release.Name }}-airflow-variables':
+ data: |
+ AIRFLOW_VAR_HELLO_MESSAGE: "Hi!"

+
+Configuring Airflow
+-------------------
+
+All Airflow configuration parameters (equivalent of ``airflow.cfg``) are
+stored in
+`values.yaml <https://github.com/apache/airflow/blob/main/chart/values.yaml>`__
+under the ``config`` key . The following code demonstrates how one would
+allow webserver users to view the config from within the webserver
+application. See the bottom line of the example:
+
+.. code-block:: yaml
+
+ # Config settings to go into the mounted airflow.cfg
+ #
+ # Please note that these values are passed through the ``tpl`` function, so are
+ # all subject to being rendered as go templates. If you need to include a
+ # literal ``{{`` in a value, it must be expressed like this:
+ #
+ # a: '{{ "{{ not a template }}" }}'
+ #
+ # yamllint disable rule:line-length
+ config:
+ core:
+ dags_folder: '{{ include "airflow_dags" . }}'
+ load_examples: 'False' # <<<<<<<< This is ignored when used with the official Docker image, see below on how to load examples
+ executor: '{{ .Values.executor }}'
+ # For Airflow 1.10, backward compatibility
+ colored_console_log: 'False'
+ remote_logging: '{{- ternary "True" "False" .Values.elasticsearch.enabled }}'
+ # Authentication backend used for the experimental API
+ api:
+ auth_backend: airflow.api.auth.backend.deny_all
+ logging:
+ remote_logging: '{{- ternary "True" "False" .Values.elasticsearch.enabled }}'
+ colored_console_log: 'False'
+ metrics:
+ statsd_on: '{{ ternary "True" "False" .Values.statsd.enabled }}'
+ statsd_port: 9125
+ statsd_prefix: airflow
+ statsd_host: '{{ printf "%s-statsd" .Release.Name }}'
+ webserver:
+ enable_proxy_fix: 'True'
+ expose_config: 'True' # <<<<<<<<<< BY DEFAULT THIS IS 'False' BUT WE CHANGE IT TO 'True' PRIOR TO INSTALLING THE CHART
+
+Generally speaking, it is useful to familiarize oneself with the Airflow
+configuration prior to installing and deploying the service.
+
+.. note::
+
+ The recommended way to load example DAGs using the official Docker image and chart is to configure the ``AIRFLOW__CORE__LOAD_EXAMPLES`` environment variable
+ in ``extraEnv`` (see :doc:`Parameters reference <parameters-ref>`). Because the official Docker image has ``AIRFLOW__CORE__LOAD_EXAMPLES=False``
+ set within the image, so you need to override it when deploying the chart.

+
+Installing the Chart
+--------------------
+
+To install this chart using helm 3, run the following commands:
+
+.. code-block:: bash
+
+ kubectl create namespace airflow
+ helm repo add apache-airflow https://airflow.apache.org
+ helm install airflow apache-airflow/airflow --namespace airflow
+
+The command deploys Airflow on the Kubernetes cluster in the default configuration. The :doc:`parameters-ref`
+section lists the parameters that can be configured during installation.
+
+
+.. tip:: List all releases using ``helm list``.
+
+Upgrading the Chart
+-------------------
+
+To upgrade the chart with the release name ``airflow``:
+
+.. code-block:: bash
+
+ helm upgrade airflow apache-airflow/airflow --namespace airflow
+
+.. note::
+ To upgrade to a new version of the chart, run ``helm repo update`` first.
+
+Uninstalling the Chart
+----------------------
+
+To uninstall/delete the ``airflow`` deployment:
+
+.. code-block:: bash
+
+ helm delete airflow --namespace airflow
+
+The command removes all the Kubernetes components associated with the chart and deletes the release.

+Installing Helm Chart from sources
+----------------------------------
+
+.. contents:: :local:
+
+
+Released packages
+'''''''''''''''''
+
+.. jinja:: official_download_page
+
+ This page describes downloading and verifying ``Apache Airflow Official Helm Chart`` version
+ ``{{ package_version}}`` using officially released source packages. You can also install the chart
+ directly from the ``airflow.apache.org`` repo as described in
+ `Installing the chart <index#installing-the-chart>`_.
+ You can choose different version of the chart by selecting different version from the drop-down at
+ the top-left of the page.
+
+
+The sources and packages released are the "official" sources of installation that you can use if
+you want to verify the origin of the packages and want to verify checksums and signatures of the packages.
+The packages are available via the
+`Official Apache Software Foundations Mirrors <http://ws.apache.org/mirrors.cgi>`_
+
+The downloads are available at:
+
+.. jinja:: official_download_page
+
+ * `Sources package <{{ closer_lua_url }}/{{ package_version }}/airflow-chart-{{ package_version }}-source.tar.gz>`__ (`asc <{{ base_url }}/{{ package_version }}/airflow-chart-{{ package_version }}-source.tar.gz.asc>`__, `sha512 <{{ base_url }}/{{ package_version }}/airflow-chart-{{ package_version }}-source.tar.gz.sha512>`__)
+ * `Installable package <{{ closer_lua_url }}/{{ package_version }}/airflow-chart-{{ package_version }}.tar.gz>`__ (`asc <{{ base_url }}/{{ package_version }}/airflow-chart-{{ package_version }}.tar.gz.asc>`__, `sha512 <{{ base_url }}/{{ package_version }}/airflow-chart-{{ package_version }}.tar.gz.sha512>`__)
+
+If you want to install from the source code, you can download from the sources link above, it will contain
+a ``INSTALL`` file containing details on how you can build and install the chart.
+
+Release integrity
+'''''''''''''''''
+
+`PGP signatures KEYS <https://downloads.apache.org/airflow/KEYS>`_
+
+It is essential that you verify the integrity of the downloaded files using the PGP or SHA signatures.
+The PGP signatures can be verified using GPG or PGP. Please download the KEYS as well as the asc
+signature files for relevant distribution. It is recommended to get these files from the
+main distribution directory and not from the mirrors.
+
+.. code-block:: bash
+
+ gpg -i KEYS
+
+or
+
+.. code-block:: bash
+
+ pgpk -a KEYS
+
+or
+
+.. code-block:: bash
+
+ pgp -ka KEYS
+
+To verify the binaries/sources you can download the relevant asc files for it from main
+distribution directory and follow the below guide.
+
+.. code-block:: bash
+
+ gpg --verify airflow-chart-********.asc airflow-chart-*********
+
+or
+
+.. code-block:: bash
+
+ pgpv airflow-chart-********.asc
+
+or
+
+.. code-block:: bash
+
+ pgp airflow-chart-********.asc
+
+Example:
+
+.. jinja:: official_download_page
+
+ .. code-block:: console
+ :substitutions:
+
+ $ gpg --verify airflow-chart-{{ package_version }}.tar.gz.asc airflow-chart-{{ package_version }}.tar.gz
+ gpg: Signature made Sat 11 Sep 12:49:54 2021 BST
+ gpg: using RSA key CDE15C6E4D3A8EC4ECF4BA4B6674E08AD7DE406F
+ gpg: issuer "kaxilnaik@apache.org"
+ gpg: Good signature from "Kaxil Naik <ka...@apache.org>" [unknown]
+ gpg: aka "Kaxil Naik <ka...@gmail.com>" [unknown]
+ gpg: WARNING: The key's User ID is not certified with a trusted signature!
+ gpg: There is no indication that the signature belongs to the owner.
+ Primary key fingerprint: CDE1 5C6E 4D3A 8EC4 ECF4 BA4B 6674 E08A D7DE 406F
+
+ The "Good signature from ..." is indication that the signatures are correct.
+ Do not worry about the "not certified with a trusted signature" warning. Most of the certificates used
+ by release managers are self signed, that's why you get this warning. By importing the server in the
+ previous step and importing it via ID from ``KEYS`` page, you know that this is a valid Key already.
+
+ For SHA512 sum check, download the relevant ``sha512`` and run the following:
+
+ .. code-block:: bash
+
+ shasum -a 512 airflow-chart-******** | diff - airflow-chart-********.sha512
+
+ The ``SHASUM`` of the file should match the one provided in ``.sha512`` file.
+
+ Example:
+
+ .. code-block:: bash
+ :substitutions:
+
+ shasum -a 512 airflow-chart-{{ package_version }}.tar.gz | diff - airflow-chart-{{ package_version }}.tar.gz.sha512

+
+Autoscaling with KEDA
+---------------------
+
+*This feature is still experimental.*
+
+KEDA stands for Kubernetes Event Driven Autoscaling.
+`KEDA <https://github.com/kedacore/keda>`__ is a custom controller that
+allows users to create custom bindings to the Kubernetes `Horizontal Pod
+Autoscaler <https://kubernetes.io/docs/tasks/run-application/horizontal-pod-autoscale/>`__.
+The autoscaler will adjust the number of active celery workers based on the number
+of tasks in ``queued`` or ``running`` state.
+
+.. code-block:: bash
+
+ helm repo add kedacore https://kedacore.github.io/charts
+
+ helm repo update
+
+ kubectl create namespace keda
+
+ helm install keda kedacore/keda \
+ --namespace keda \
+ --version "v2.0.0"
+
+Enable for the airflow instance by setting ``workers.keda.enabled=true`` in your
+helm command or in the ``values.yaml``.
+
+.. code-block:: bash
+
+ kubectl create namespace airflow
+ helm repo add apache-airflow https://airflow.apache.org
+ helm install airflow apache-airflow/airflow \
+ --namespace airflow \
+ --set executor=CeleryExecutor \
+ --set workers.keda.enabled=true \
+
+A ``ScaledObject`` and an ``hpa`` will be created in the airflow namespace.
+
+KEDA will derive the desired number of celery workers by querying
+Airflow metadata database:
+
+.. code-block:: none
+
+ SELECT
+ ceil(COUNT(*)::decimal / {{ .Values.config.celery.worker_concurrency }})
+ FROM task_instance
+ WHERE state='running' OR state='queued'
+
+.. note::
+
+ Set celery worker concurrency through the helm value
+ ``config.celery.worker_concurrency`` (i.e. instead of airflow.cfg or
+ environment variables) so that the KEDA trigger will be consistent with
+ the worker concurrency setting.

+
+Manage DAGs files
+=================
+
+When you create new or modify existing DAG files, it is necessary to deploy them into the environment. This section will describe some basic techniques you can use.
+
+Bake DAGs in Docker image
+-------------------------
+
+The recommended way to update your DAGs with this chart is to build a new docker image with the latest DAG code:
+
+.. code-block:: bash
+
+ docker build --tag "my-company/airflow:8a0da78" . -f - <<EOF
+ FROM apache/airflow
+
+ COPY ./dags/ \${AIRFLOW_HOME}/dags/
+
+ EOF
+
+.. note::
+
+ In airflow images prior to version 2.0.2, there was a bug that required you to use
+ a bit longer Dockerfile, to make sure the image remains OpenShift-compatible (i.e dag
+ has root group similarly as other files). In 2.0.2 this has been fixed.
+
+.. code-block:: bash
+
+ docker build --tag "my-company/airflow:8a0da78" . -f - <<EOF
+ FROM apache/airflow:2.0.2
+
+ USER root
+
+ COPY --chown=airflow:root ./dags/ \${AIRFLOW_HOME}/dags/
+
+ USER airflow
+
+ EOF
+
+
+Then publish it in the accessible registry:
+
+.. code-block:: bash
+
+ docker push my-company/airflow:8a0da78
+
+Finally, update the Airflow pods with that image:
+
+.. code-block:: bash
+
+ helm upgrade --install airflow apache-airflow/airflow \
+ --set images.airflow.repository=my-company/airflow \
+ --set images.airflow.tag=8a0da78
+
+If you are deploying an image with a constant tag, you need to make sure that the image is pulled every time.
+
+.. code-block:: bash
+
+ helm upgrade --install airflow apache-airflow/airflow \
+ --set images.airflow.repository=my-company/airflow \
+ --set images.airflow.tag=8a0da78 \
+ --set images.airflow.pullPolicy=Always
+
+Mounting DAGs using Git-Sync sidecar with Persistence enabled
+-------------------------------------------------------------
+
+This option will use a Persistent Volume Claim with an access mode of ``ReadWriteMany``.
+The scheduler pod will sync DAGs from a git repository onto the PVC every configured number of
+seconds. The other pods will read the synced DAGs. Not all volume plugins have support for
+``ReadWriteMany`` access mode.
+Refer `Persistent Volume Access Modes <https://kubernetes.io/docs/concepts/storage/persistent-volumes/#access-modes>`__
+for details.
+
+.. code-block:: bash
+
+ helm upgrade --install airflow apache-airflow/airflow \
+ --set dags.persistence.enabled=true \
+ --set dags.gitSync.enabled=true
+ # you can also override the other persistence or gitSync values
+ # by setting the dags.persistence.* and dags.gitSync.* values
+ # Please refer to values.yaml for details
+
+.. code-block:: bash
+
+ helm upgrade --install airflow apache-airflow/airflow \
+ --set dags.persistence.enabled=true \
+ --set dags.gitSync.enabled=true \
+ # you can also override the other persistence or gitSync values
+ # by setting the dags.persistence.* and dags.gitSync.* values
+ # Please refer to values.yaml for details
+
+Mounting DAGs using Git-Sync sidecar without Persistence
+--------------------------------------------------------
+
+This option will use an always running Git-Sync sidecar on every scheduler, webserver (if ``airflowVersion < 2.0.0``)
+and worker pods.
+The Git-Sync sidecar containers will sync DAGs from a git repository every configured number of
+seconds. If you are using the ``KubernetesExecutor``, Git-sync will run as an init container on your worker pods.
+
+.. code-block:: bash
+
+ helm upgrade --install airflow apache-airflow/airflow \
+ --set dags.persistence.enabled=false \
+ --set dags.gitSync.enabled=true
+ # you can also override the other gitSync values
+ # by setting the dags.gitSync.* values
+ # Refer values.yaml for details
+
+When using ``apache-airflow>=2.0.0``, :ref:`DAG Serialization <apache-airflow:dag-serialization>` is enabled by default,
+hence Webserver does not need access to DAG files, so ``git-sync`` sidecar is not run on Webserver.
+
+Mounting DAGs from an externally populated PVC
+----------------------------------------------
+
+In this approach, Airflow will read the DAGs from a PVC which has ``ReadOnlyMany`` or ``ReadWriteMany`` access mode. You will have to ensure that the PVC is populated/updated with the required DAGs(this won't be handled by the chart). You can pass in the name of the volume claim to the chart
+
+.. code-block:: bash
+
+ helm upgrade --install airflow apache-airflow/airflow \
+ --set dags.persistence.enabled=true \
+ --set dags.persistence.existingClaim=my-volume-claim
+ --set dags.gitSync.enabled=false
+
+Mounting DAGs from a private Github repo using Git-Sync sidecar
+---------------------------------------------------------------
+Create a private repo on Github if you have not created one already.
+
+Then create your ssh keys:
+
+.. code-block:: bash
+
+ ssh-keygen -t rsa -b 4096 -C "your_email@example.com"
+
+Add the public key to your private repo (under ``Settings > Deploy keys``).
+
+You have to convert the private ssh key to a base64 string. You can convert the private ssh key file like so:
+
+.. code-block:: bash
+
+ base64 <my-private-ssh-key> -w 0 > temp.txt
+
+Then copy the string from the ``temp.txt`` file. You'll add it to your ``override-values.yaml`` next.
+
+In this example, you will create a yaml file called ``override-values.yaml`` to override values in the
+``values.yaml`` file, instead of using ``--set``:
+
+.. code-block:: yaml
+
+ dags:
+ gitSync:
+ enabled: true
+ repo: ssh://git@github.com/<username>/<private-repo-name>.git
+ branch: <branch-name>
+ subPath: ""
+ sshKeySecret: airflow-ssh-secret
+ extraSecrets:
+ airflow-ssh-secret:
+ data: |
+ gitSshKey: '<base64-converted-ssh-private-key>'
+
+Don't forget to copy in your private key base64 string.
+
+Finally, from the context of your Airflow Helm chart directory, you can install Airflow:
+
+.. code-block:: bash
+
+ helm upgrade --install airflow apache-airflow/airflow -f override-values.yaml
+
+If you have done everything correctly, Git-Sync will pick up the changes you make to the DAGs
+in your private Github repo.
+
+You should take this a step further and set ``dags.gitSync.knownHosts`` so you are not susceptible to man-in-the-middle
+attacks. This process is documented in the :ref:`production guide <production-guide:knownhosts>`.

+
+Manage logs
+=================
+
+You have a number of options when it comes to managing your Airflow logs.
+
+No persistence
+-----------------
+
+With this option, Airflow will log locally to each pod. As such, the logs will only be available during the lifetime of the pod.
+
+.. code-block:: bash
+
+ helm upgrade --install airflow apache-airflow/airflow \
+ --set logs.persistence.enabled=false
+ # --set workers.persistence.enabled=false (also needed if using ``CeleryExecutor``)
+
+Celery worker log persistence
+-----------------------------
+
+If you are using ``CeleryExecutor``, workers persist logs by default to a volume claim created with a ``volumeClaimTemplate``.
+
+You can modify the template:
+
+.. code-block:: bash
+
+ helm upgrade --install airflow apache-airflow/airflow \
+ --set executor=CeleryExecutor \
+ --set workers.persistence.size=10Gi
+
+Note with this option only task logs are persisted, unlike when log persistence is enabled which will also persist scheduler logs.
+
+Log persistence enabled
+-----------------------
+
+This option will provision a ``PersistentVolumeClaim`` with an access mode of ``ReadWriteMany``. Each component of Airflow will
+then log onto the same volume.
+
+Not all volume plugins have support for ``ReadWriteMany`` access mode.
+Refer `Persistent Volume Access Modes <https://kubernetes.io/docs/concepts/storage/persistent-volumes/#access-modes>`__
+for details.
+
+.. code-block:: bash
+
+ helm upgrade --install airflow apache-airflow/airflow \
+ --set logs.persistence.enabled=true
+ # you can also override the other persistence
+ # by setting the logs.persistence.* values
+ # Please refer to values.yaml for details
+
+Externally provisioned PVC
+--------------------------
+
+In this approach, Airflow will log to an existing ``ReadWriteMany`` PVC. You pass in the name of the volume claim to the chart.
+
+.. code-block:: bash
+
+ helm upgrade --install airflow apache-airflow/airflow \
+ --set logs.persistence.enabled=true \
+ --set logs.persistence.existingClaim=my-volume-claim
+
+Note that the volume will need to writable by the Airflow user. The easiest way is to ensure GID ``0`` has write permission.
+More information can be found in the :ref:`Docker image entrypoint documentation <docker-stack:arbitrary-docker-user>`.
+
+Elasticsearch
+-------------
+
+If your cluster forwards logs to Elasticsearch, you can configure Airflow to retrieve task logs from it.
+See the :doc:`Elasticsearch providers guide <apache-airflow-providers-elasticsearch:logging/index>` for more details.
+
+.. code-block:: bash
+
+ helm upgrade --install airflow apache-airflow/airflow \
+ --set elasticsearch.enabled=true \
+ --set elasticsearch.secretName=my-es-secret
+ # Other choices exist. Please refer to values.yaml for details.

+Production Guide
+================
+
+The following are things to consider when using this Helm chart in a production environment.
+
+Database
+--------
+
+You will want to use an external database instead of the one deployed with the chart by default.
+Both **PostgresSQL** and **MySQL** are supported. Supported versions can be
+found on the :doc:`Set up a Database Backend <apache-airflow:howto/set-up-database>` page.
+
+.. code-block:: yaml
+
+ # Don't deploy postgres
+ postgresql:
+ enabled: false
+
+ # Use an external database
+ data:
+ metadataConnection:
+ user: ...
+ pass: ...
+ protocol: postgresql # or 'mysql'
+ host: ...
+ port: ...

+
+If you are using PostgresSQL as your database, you will likely want to enable `PgBouncer <https://www.pgbouncer.org/>`_ as well.
+Airflow can open a lot of database connections due to its distributed nature and using a connection pooler can significantly
+reduce the number of open connections on the database.
+
+.. code-block:: yaml
+
+ pgbouncer:
+ enabled: true
+
+Depending on the size of you Airflow instance, you may want to adjust the following as well (defaults are shown):
+
+.. code-block:: yaml
+
+ pgbouncer:
+ # The maximum number of connections to PgBouncer
+ maxClientConn: 100
+ # The maximum number of server connections to the metadata database from PgBouncer
+ metadataPoolSize: 10
+ # The maximum number of server connections to the result backend database from PgBouncer
+ resultBackendPoolSize: 5
+
+Webserver Secret Key
+--------------------
+
+You should set a static webserver secret key when deploying with this chart as it will help ensure
+your Airflow components only restart when necessary.
+
+.. warning::
+ You should use a different secret key for every instance you run, as this key is used to sign
+ session cookies and perform other security related functions!
+
+First, generate a strong secret key:
+
+.. code-block:: bash
+
+ python3 -c 'import secrets; print(secrets.token_hex(16))'
+
+Now add the secret to your values file:
+
+.. code-block:: yaml
+
+ webserverSecretKey: <secret_key>
+
+Alternatively, create a kubernetes Secret and use ``webserverSecretKeySecretName``:
+
+.. code-block:: yaml
+
+ webserverSecretKey: my-webserver-secret
+ # where the random key is under `webserver-secret-key` in the k8s Secret
+
+Extending and customizing Airflow Image
+---------------------------------------
+
+The Apache Airflow community, releases Docker Images which are ``reference images`` for Apache Airflow.
+However, Airflow has more than 60 community managed providers (installable via extras) and some of the
+default extras/providers installed are not used by everyone, sometimes others extras/providers
+are needed, sometimes (very often actually) you need to add your own custom dependencies,
+packages or even custom providers, or add custom tools and binaries that are needed in
+your deployment.
+
+In Kubernetes and Docker terms this means that you need another image with your specific requirements.
+This is why you should learn how to build your own ``Docker`` (or more properly ``Container``) image.
+
+Typical scenarios where you would like to use your custom image:
+
+* Adding ``apt`` packages
+* Adding ``PyPI`` packages
+* Adding binary resources necessary for your deployment
+* Adding custom tools needed in your deployment
+
+See `Building the image <https://airflow.apache.org/docs/docker-stack/build.html>`_ for more
+details on how you can extend and customize the Airflow image.
+
+Managing DAG Files
+------------------
+
+See :doc:`manage-dags-files`.
+
+.. _production-guide:knownhosts:
+
+knownHosts
+^^^^^^^^^^
+
+If you are using ``dags.gitSync.sshKeySecret``, you should also set ``dags.gitSync.knownHosts``. Here we will show the process
+for GitHub, but the same can be done for any provider:
+
+Grab GitHub's public key:
+
+.. code-block:: bash
+
+ ssh-keyscan -t rsa github.com > github_public_key
+
+Next, print the fingerprint for the public key:
+
+.. code-block:: bash
+
+ ssh-keygen -lf github_public_key
+
+Compare that output with `GitHub's SSH key fingerprints <https://docs.github.com/en/github/authenticating-to-github/githubs-ssh-key-fingerprints>`_.
+
+They match, right? Good. Now, add the public key to your values. It'll look something like this:
+
+.. code-block:: yaml
+
+ dags:
+ gitSync:
+ knownHosts: |
+ github.com ssh-rsa AAAA...FAaQ==
+
+
+Accessing the Airflow UI
+------------------------
+
+How you access the Airflow UI will depend on your environment, however the chart does support various options:
+
+Ingress
+^^^^^^^
+
+You can create and configure ``Ingress`` objects. See the :ref:`Ingress chart parameters <parameters:ingress>`.
+For more information on ``Ingress``, see the
+`Kubernetes Ingress documentation <https://kubernetes.io/docs/concepts/services-networking/ingress/>`_.
+
+LoadBalancer Service
+^^^^^^^^^^^^^^^^^^^^
+
+You can change the Service type for the webserver to be ``LoadBalancer``, and set any necessary annotations:
+
+.. code-block:: yaml
+
+ webserver:
+ service: LoadBalancer
+ annotations: {}
+
+For more information on ``LoadBalancer`` Services, see the `Kubernetes LoadBalancer Service Documentation
+<https://kubernetes.io/docs/concepts/services-networking/service/#loadbalancer>`_.
+
+Logging
+-------
+
+Depending on your choice of executor, task logs may not work out of the box. All logging choices can be found
+at :doc:`manage-logs`.
+
+Metrics
+-------
+
+The chart can support sending metrics to an existing StatsD instance or provide a Prometheus endpoint.
+
+Prometheus
+^^^^^^^^^^
+
+The metrics endpoint is available at ``svc/{{ .Release.Name }}-statsd:9102/metrics``.
+
+External StatsD
+^^^^^^^^^^^^^^^
+
+To use an external StatsD instance:
+
+.. code-block:: yaml
+
+ statsd:
+ enabled: false
+ config:
+ metrics: # or 'scheduler' for Airflow 1
+ statsd_on: true
+ statsd_host: ...
+ statsd_port: ...
+
+Celery Backend
+--------------
+
+If you are using ``CeleryExecutor`` or ``CeleryKubernetesExecutor``, you can bring your own Celery backend.
+
+By default, the chart will deploy Redis. However, you can use any supported Celery backend instead:
+
+.. code-block:: yaml
+
+ redis:
+ enabled: false
+ data:
+ brokerUrl: redis://redis-user:password@redis-host:6379/0
+
+For more information about setting up a Celery broker, refer to the
+exhaustive `Celery documentation on the topic <http://docs.celeryproject.org/en/latest/getting-started/>`_.

+
+Quick start with kind
+=====================
+
+This article will show you how to install Airflow using Helm Chart on `Kind <https://kind.sigs.k8s.io/>`__
+
+Install kind, and create a cluster
+----------------------------------
+
+We recommend testing with Kubernetes 1.16+, example:
+
+.. code-block:: bash
+
+ kind create cluster --image kindest/node:v1.18.15
+
+Confirm it’s up:
+
+.. code-block:: bash
+
+ kubectl cluster-info --context kind-kind
+
+Add Airflow Helm Stable Repo
+----------------------------
+
+.. code-block:: bash
+
+ helm repo add apache-airflow https://airflow.apache.org
+ helm repo update
+
+Create namespace
+----------------
+
+.. code-block:: bash
+
+ export NAMESPACE=example-namespace
+ kubectl create namespace $NAMESPACE
+
+Install the chart
+-----------------
+
+.. code-block:: bash
+
+ export RELEASE_NAME=example-release
+ helm install $RELEASE_NAME apache-airflow/airflow --namespace $NAMESPACE
+
+Use the following code to install the chart with Example DAGs:
+
+.. code-block:: bash
+
+ export NAMESPACE=example-namespace
+ helm install $RELEASE_NAME apache-airflow/airflow \
+ --namespace $NAMESPACE \
+ --set 'env[0].name=AIRFLOW__CORE__LOAD_EXAMPLES,env[0].value=True'
+
+It may take a few minutes. Confirm the pods are up:
+
+.. code-block:: bash
+
+ kubectl get pods --namespace $NAMESPACE
+ helm list --namespace $NAMESPACE
+
+Run the following command
+to port-forward the Airflow UI to http://localhost:8080/ to confirm
+Airflow is working.
+
+.. code-block:: bash
+
+ kubectl port-forward svc/$RELEASE_NAME-webserver 8080:8080 --namespace $NAMESPACE
+
+Extending Airflow Image
+-----------------------
+
+The Apache Airflow community, releases Docker Images which are ``reference images`` for Apache Airflow.
+However when you try it out you want to add your own DAGS, custom dependencies,
+packages or even custom providers.
+
+The best way to achieve it, is to build your own, custom image.
+
+Adding DAGs to your image
+.........................
+
+1. Create a project
+
+ .. code-block:: bash
+
+ mkdir my-airflow-project && cd my-airflow-project
+ mkdir dags # put dags here
+ cat <<EOM > Dockerfile
+ FROM apache/airflow
+ COPY . .
+ EOM
+
+
+2. Then build the image:
+
+ .. code-block:: bash
+
+ docker build --tag my-dags:0.0.1 .
+
+
+3. Load the image into kind:
+
+ .. code-block:: bash
+
+ kind load docker-image my-dags:0.0.1
+
+4. Upgrade Helm deployment:
+
+ .. code-block:: bash
+
+ helm upgrade $RELEASE_NAME apache-airflow/airflow --namespace $NAMESPACE \
+ --set images.airflow.repository=my-dags \
+ --set images.airflow.tag=0.0.1
+
+Adding ``apt`` packages to your image
+.....................................
+
+Example below adds ``vim`` apt package.
+
+1. Create a project
+
+ .. code-block:: bash
+
+ mkdir my-airflow-project && cd my-airflow-project
+ cat <<EOM > Dockerfile
+ FROM apache/airflow
+ USER root
+ RUN apt-get update \
+ && apt-get install -y --no-install-recommends \
+ vim \
+ && apt-get autoremove -yqq --purge \
+ && apt-get clean \
+ && rm -rf /var/lib/apt/lists/*
+ USER airflow
+ EOM
+
+
+2. Then build the image:
+
+ .. code-block:: bash
+
+ docker build --tag my-image:0.0.1 .
+
+
+3. Load the image into kind:
+
+ .. code-block:: bash
+
+ kind load docker-image my-image:0.0.1
+
+4. Upgrade Helm deployment:
+
+ .. code-block:: bash
+
+ helm upgrade $RELEASE_NAME apache-airflow/airflow --namespace $NAMESPACE \
+ --set images.airflow.repository=my-image \
+ --set images.airflow.tag=0.0.1
+
+Adding ``PyPI`` packages to your image
+......................................
+
+Example below adds ``lxml`` PyPI package.
+
+1. Create a project
+
+ .. code-block:: bash
+
+ mkdir my-airflow-project && cd my-airflow-project
+ cat <<EOM > Dockerfile
+ FROM apache/airflow
+ RUN pip install --no-cache-dir lxml
+ EOM
+
+
+2. Then build the image:
+
+ .. code-block:: bash
+
+ docker build --tag my-image:0.0.1 .
+
+
+3. Load the image into kind:
+
+ .. code-block:: bash
+
+ kind load docker-image my-image:0.0.1
+
+4. Upgrade Helm deployment:
+
+ .. code-block:: bash
+
+ helm upgrade $RELEASE_NAME apache-airflow/airflow --namespace $NAMESPACE \
+ --set images.airflow.repository=my-image \
+ --set images.airflow.tag=0.0.1
+
+Further extending and customizing the image
+...........................................
+
+See `Building the image <https://airflow.apache.org/docs/docker-stack/build.html>`_ for more
+details on how you can extend and customize the Airflow image.

+
+Using additional containers
+===========================
+
+Sidecar Containers
+------------------
+
+If you want to deploy your own sidecar container, you can add it through the ``extraContainers`` parameter.
+You can define different containers for the scheduler, webserver and worker pods.
+
+For example, sidecars that sync DAGs from object storage.
+
+.. code-block:: yaml
+
+ scheduler:
+ extraContainers:
+ - name: s3-sync
+ image: my-company/s3-sync:latest
+ imagePullPolicy: Always
+ workers:
+ extraContainers:
+ - name: s3-sync
+ image: my-company/s3-sync:latest
+ imagePullPolicy: Always
+
+.. note::
+
+ If you use ``workers.extraContainers`` with ``KubernetesExecutor``, you are responsible for signaling
+ sidecars to exit when the main container finishes so Airflow can continue the worker shutdown process!
+
+
+Init Containers
+---------------
+
+You can also deploy extra init containers through the ``extraInitContainers`` parameter.
+You can define different containers for the scheduler, webserver and worker pods.
+
+For example, an init container that just says hello:
+
+.. code-block:: yaml
+
+ scheduler:
+ extraInitContainers:
+ - name: hello
+ image: debian
+ args:
+ - echo
+ - hello
