While I do not agree with _every_ style change, this will force Dokku to have consistent formatting across all shell scripts, which is arguably a Good Thing™.
The command used to reprocess everything is:
```shell
shfmt -l -bn -ci -i 2 -w .
```
These will be killed on a cron schedule, allowing us to ensure old containers don't run once memory pressure clears up - even across restarts.
Closes#3225
This can be useful in cases where a developer wishes to see what error messages are available for a failed deploy, but does not wish to spelunk around `docker ps -a` output.
Note that the logs are not made available once a further deploy is triggered, or after the containers have been garbage collected.
