Wouter-M opened a new pull request #3741: [AIRFLOW-1368] Add auto_remove for DockerOperator
URL: https://github.com/apache/incubator-airflow/pull/3741
 
 
   Dear Airflow maintainers,
   
   Please take this PR into consideration. It adds the ability for containers created by the `DockerOperator` to be removed automatically after execution. 
   
   Make sure you have checked _all_ steps below.
   
   ### Jira
   
   - [x] My PR addresses the following [Airflow Jira](https://issues.apache.org/jira/browse/AIRFLOW/) issues and references them in the PR title. For example, "\[AIRFLOW-XXX\] My Airflow PR"
     - https://issues.apache.org/jira/browse/AIRFLOW-1368
   
   Other issues which seem to be duplicate:
   - https://issues.apache.org/jira/browse/AIRFLOW-516
   - https://issues.apache.org/jira/browse/AIRFLOW-465
   
   ### Description
   
   - [x] Here are some details about my PR, including screenshots of any UI changes:
   
   This PR adds back the `auto_remove` option to the `DockerOperator`, which will automatically delete the Docker container once it exits. This was added before in PR #2411, but something went wrong there and it somehow got lost.
   
   ### Tests
   
   - [x] My PR adds the following unit tests __OR__ does not need testing for this extremely good reason:
   
   I have changed one of the unit tests to work with the change, ran the test cases for the docker_operator, and testing airflow locally to check the docker container gets removed if `auto_remove=True` and not removed if `auto_remove=False`.
   
   ### Commits
   
   - [x] My commits all reference Jira issues in their subject lines, and I have squashed multiple commits if they address the same issue. In addition, my commits follow the guidelines from "[How to write a good git commit message](http://chris.beams.io/posts/git-commit/)":
     1. Subject is separated from body by a blank line
     1. Subject is limited to 50 characters (not including Jira issue reference)
     1. Subject does not end with a period
     1. Subject uses the imperative mood ("add", not "adding")
     1. Body wraps at 72 characters
     1. Body explains "what" and "why", not "how"
   
   ### Documentation
   
   - [x] In case of new functionality, my PR adds documentation that describes how to use it.
     - When adding new operators/hooks/sensors, the autoclass documentation generation needs to be added.
   
   I updated the doc comment.
   
   ### Code Quality
   
   - [x] Passes `git diff upstream/master -u -- "*.py" | flake8 --diff`
