The Docker registry plugin for Dokku adds support for managing application releases as part of a continuous delivery workflow.
On Heroku similar functionality is offered by the heroku-labs pipeline feature, which allows you to promote builds across multiple environments (staging -> production)
- dokku 0.4.0+
- docker 1.8.x
# on 0.3.x
cd /var/lib/dokku/plugins
git clone https://github.com/agco/dokku-registry.git registry
dokku plugins-install
# on 0.4.x
dokku plugin:install https://github.com/agco/dokku-registry.git registry$ dokku help
registry:login <docker login args> Login to a docker registry
registry:push <git_url> <docker_registry_image> Clone a git url, exec buildstep and push the resulting Docker image to the logged on registry
registry:pull <app> <docker_registry_image> Pull a Docker image (produced with buildstep) from the logged on registry and deploy
dokku registry:login —username=<username> —password=<password> —email=<email> <server>
This logs you in to the dockerhub registry Other registries can be specified as well with using the optional server arg Check the docker login docs for more details
dokku registry:push <git_url> <image_tag>
This clones the code from a given git_url and builds it with buildstep The resulting Docker is tagged as specified by the image_tag arg and pushed to the current logged-on Docker registry
dokku registry:login —username=<username> —password=<password> —email=<email> <server>
dokku registry:pull <appname> <image_tag>
This pulls the image tag from the current logged-on registry and deploys it to Dokku. The application will be auto-created in case it doesn't exist yet.
Note : This is just to demonstrate syntax, replace credentials and registry image tag with your own values
dokku registry:login --username=myusername [email protected] --password=mypwd
dokku registry:push https://github.com/heroku/node-js-getting-started.git myusername/myapp:1.2.3
dokku registry:pull myapp myusername/myapp:1.2.3
The workflow then looks something like the following
dokku registry:login --username=myusername [email protected] --password=mypwd
dokku create myapp
dokku config:set myapp FOO=BAR
dokku registry:pull myapp myusername/myapp:1.2.3
