dokku-deploy-from-registry

This plugin enables you to specify a registry for Dokku to pull an image from, and then deploy it to an app.

The goal is to streamline the deployment process for container images. For instance, in a CI job that builds an image and pushes it to a registry.

Installation

dokku plugin:install https://github.com/yurihs/dokku-deploy-from-registry.git deploy-from-registry

Usage

First, set the remote image repo for an app, like so:

dokku deploy-from-registry:set-remote-image-repo some-app registry.example.com/my-org/my-app

Then you can run

dokku deploy-from-registry some-app a1b2c3

to pull the a1b2c3 tag and deploy it. After confirming that it works, you can stick that command in your CI pipeline as a simple, one-command deploy solution.

Bonus: use dokku-acl to restrict access to the deploy command. Put deploy-from-registry in your DOKKU_ACL_PER_APP_COMMANDS environment variable, and you should be good.

Commands

deploy-from-registry <app> <tag>                          pull and deploy
deploy-from-registry:get-remote-image-repo <app>          get image repo
deploy-from-registry:set-remote-image-repo <app> <repo>   set image repo to pull from
deploy-from-registry:unset-remote-image-repo <app>        unset image repo
