Rather than attempting to always extract the Procfile, reference the one that was extracted by the last deploy. This fixes issues where 'docker container cp' may fail intermittently for lord knows what reason.
Closes#4083
Rather than waiting for the next deploy, take advantage of the retire system to retire these containers immediately.
Note that since the retire process happens out of band, the containers may stick around for up to 5 minutes, after which point they will be removed.
Customization of the wait time to retire - currently 60 seconds - is up for future debate. The containers ultimately haven't been useful for debugging, so keeping them around for longer won't help in most cases, and folks can disable the dokku-retire service (or cron) if that is desired.
Better would be to separate the release and deploy aspects into distinct triggers - as well as have it release a specific image - but this is a good first pass.
Heroku's ruby project changed its default branch from master to main.
This broke the examples in the documentation. This change explicitly
names main and master.
This is necessary for ensuring ssl certificates can be auto-retrieved for apps, and also easing integration into schedulers that use names and process types as part of DNS records.
As well, this fixes an issue where we may potentially have invalid DNS entries when adding apps to custom networks.
Closes#4102Closes#4114
Dokku internals shouldn't be exposed in docs. Additionally, the internals here are likely to change in the future as this moves to the upcoming prop binary, so having incorrect docs will hinder that move.
Previous versions extracted the values as strings, prefixing the values with `/bin/sh -c '$CMD'` unnecessarily. This caused issues where we would incorrectly overrride these values when an app had a predeploy script.
Closes#3143
