erlang-s2i

alpine images for building and running Erlang on OpenShift

• Based on the official Erlang Docker images
  • Alpine base
  • Assumes the application is listening on ports 8080 and/or 8443
• Uses separate build and runtime images
  • s2i does not support Docker build stages, but this concept is close

See the s2i docs for more detailed information.

Getting the images

$ docker pull donkeybanana/s2i-erlang-builder
$ docker pull donkeybanana/s2i-erlang-runtime

Alternatively, clone this repo and build locally

$ make images

# or

$ docker build -t donkeybanana/s2i-erlang-builder builder
$ docker build -t donkeybanana/s2i-erlang-runtime runtime

Local Usage (with s2i)

Using https://github.com/erlang/docker-erlang-example as our example application:

# Clone the application repository
$ git clone https://github.com/erlang/docker-erlang-example

# Run s2i
$ s2i build docker-erlang-example/dockerwatch \ # local path as build input
            donkeybanana/s2i-erlang-builder \ # builder image
            --runtime-image donkeybanana/s2i-erlang-runtime \ # specify runtime image
            donkeybanana/erlang-dockerwatch # output image
