Configure grace period

[michel-kraemer]

It would be great if one could configure the grace period $GRACE_PERIOD_SECONDS. I suppose a good way would be to have a /etc/default/docker-gc file that you can source in your script. Such a file would just contain one line export GRACE_PERIOD_SECONDS=3600.

This would help a lot! Thanks!

This line will actually use the variable if it's already set, so you can just change your (cron?) entry to set the env var.

GRACE_PERIOD_SECONDS=3600 /path/to/docker-gc

I think that'd work.

[michel-kraemer]

Sure. I can do that. I was just thinking that a /etc/default/docker-gc file would probably be a bit more transparent. I don't think it would be much work to add it. I could try to submit a pull request, but I'm super busy with other projects at the moment. Maybe later.

Hey @michel-kraemer as mentioned above you can just set GRACE_PERIOD_SECONDS=whatever when invoking the script. I think we'd prefer to keep the logic to configure via environment variables rather than sourcing a file to be consistent with how other options are set.
