I don't know much about docker, but the deletion of this seems that would break existing users:
COPYBARA_CONFIG=copy.bara.sky`
- allows you to specify a path to a config file, defaults to root
copy.bara.sky COPYBARA_SUBCOMMAND=migrate- allows you to change the command run, defaults to
migrate
- allows you to change the command run, defaults to
COPYBARA_OPTIONS=''- allows you to specify options for copybara, defaults to none
COPYBARA_WORKFLOW=default- allows you to specify the workflow to run, defaults to
default
- allows you to specify the workflow to run, defaults to
COPYBARA_SOURCEREF=''
|
If you want to handle environment arguments, this should definitely done by the executable itself. Adding this as a script to the container, feels like a big hack. Nevertheless, I added that functionality back to not break existing users for the time being. |

Add comment on why remove.

IIUC this is the equivalent to "apt-get clean". Any reason for using this instead?

This is suggested as best practice from Docker itself: https://docs.docker.com/develop/develop-images/dockerfile_best-practices/#apt-get
This is basically what is used in more than 99% of all Dockerfiles. Should I still add a comment?

Yes, at least in the commit description. Can you: squash all changes in one and add a commit description that explains all we are doing here?
Thanks!
This allows passing args to Copybara directly via CMD as an alternative to using environment variables.
