Add an 'add-ons' plugin, which provides heroku style addons.

[plietar]

This is still WIP. I've created the PR so people can comment it.
Add-ons provide access to services (e.g. database) by applications.

It is quite similar to heroku's addons.
Add-ons provide a URL, which is passed to applications through environment variables.
The contents of the url is up to the add-on, but should be described in the add-on's doc.

The description of how to use/create plugins is in the docs folder.

See https://github.com/plietar/dokku-addons for addons.

I have added some tests, but they are part of the dokku-addons repo, and work only in vagrant for now.

TODO

• Basic commands (add/remove/url)
• Help message
• Unprovision automatically all add-ons in pre-delete
• Manage add-ons enabling/installation (eg creation of service's container)
• Write add-ons for major services
• Add some automated testing.
• Make testing work on travis.
• Add backup-export/backup-import support. (Needs a small change in the backup PR, I'll make a PR or commit them soon)
• Start addons container after reboot (Possible integration with dokku ps dokku ps #298, or plain upstart)

Comments/suggestions are welcome.

Wow. This'll take some time to digest/review but it looks amazing.

[plietar]

Sure, this is still far from being complete, and would be for a not so soon release.

[progrium]

This'll be a great headlining feature for 0.3.0

[plietar]

It should be quite stable now, there a few non-essential things left todo.

I've written addons for mariadb, postgresql and redis.
They are on a seperate repo
https://github.com/plietar/dokku-addons

Cloning it and running make install should be enough.

Alternatively, cloning it on the host and running make vagrant will install it into the vagrant box.
The ssh keys need to be setup. (Easiest way is to run dokku's test/run_vagrant)

Any news on this?

[Peeja]

I'm not using Dokku at the moment, but a few weeks ago I was playing with it using this PR, and things worked well. I'd love to see it land on master.
