These flags are not commonly invoked by users, causing issues when cleaning up old containers. Rather than instruct users to use some random flag, just change the default to what is likely to be more common.
The previous lever for manipulating this was the DOKKU_IMAGE environment variable. While this is all well and good, it only works for CNB and is yet another `DOKKU_*` environment variable that need not exist.
While this does not add support for manipulating the CNB stack just yet, the groundwork is set for the future.
Closes#4306
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
- add `report` and `set` subcommands to the git plugin
- move configuring the DOKKU_DEPLOY_BRANCH to the git plugin
- implement configurable GIT_REV support
- migrate DOKKU_DEPLOY_BRANCH settings
- add a golang-compatible, shell based method of setting plugin configuration variables
Deprecates the community dokku-git-rev plugin.
Closes#2621
Refs dokku-community/dokku-git-rev#9
This allows developers to change the shell from /bin/bash to any other when executing
`dokku enter` or pre/post deployment tasks. Ideally we could detect the shells available,
but that is slow and potentially error prone.
Closes#2572
This adds a table of environment variables that Dokku will use to change internal behavior.
Not all are fully documented/listed, but this should be enough to get people hacking.
