The previous tar support lacked the ability to track changes between tarball deploys. Critically, it also failed to be handled correctly when there was _also_ a git deployment done on the app, resulting in odd deployment states depending on the angles of the moon and the sun in the sky.
Rather than try to "fix" this through some hokey mechanism, importing the tar file contents into the git repository is preferred, as then the user can refer to the repository for commit history.
Additionally, we add support for non-tar files (tar.gz and zip), enabling deployments from systems that do not create tar files, such as Github (their tarball url is a tar.gz file).
Finally, this deprecates the tar plugin, and sets it to be removed in the next minor release (in addition to the tags plugin).
Closes#3458Closes#4207
The new command superscedes the previous tags plugin, and integrates docker image deployment with the general build process.
While `docker image load` is not supported, this otherwise completely handles all previous workflows supported by the `tags:deploy` command, while doing so in a much easier to use interface.
Closes#4296
This standardization makes it somewhat easier to read stacktraces as the command names are all uniform, so it will be slightly easier to scan trace output.
It may be desirable to keep the contents of the git directory for the build process. Certain build tools can extract extra information from the .git directory, and some workflows may require that the shipped artifact has the entire source code available locally for later usage.
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 .
```
This is useful in contexts where the repository directory may be created and interacted with via git-http-backend or other methods of updating a repository.
- 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.
