DEPRECATED

This package is no longer under support. The release tool this package is based off of (exrm) is deprecated and replaced by distillery. Instead you should use mix_docker which makes use of Distillery.

ExrmDocker

Create a Docker image from your Elixir release

Usage

To create a new Docker image simply run:

mix release --docker

This will output the docker build result with the created image id.

To specify docker image tag you can use --tag option:

mix release --docker --tag=test:0.3

docker images
REPOSITORY   TAG   IMAGE ID       CREATED         VIRTUAL SIZE
test         0.3   6d3d5f9abac4 6 seconds ago      224.3 MB

by default it uses project name.

Once your image has been built, start a new container.

• docker run -itd <image_id> console

Next you can attach to your container.

• docker attach <container_id>

And detach using Ctrl-p Ctrl-q.

Check below for configuration options.
