Docker image with globally installed https://github.com/elm/compiler, https://github.com/rtfeldman/node-test-runner, and other tools. Suitable for testing/building Elm applications or packages in docker-based CI.

• Based on Alpine Linux image for smaller size (https://github.com/frol/docker-alpine-glibc)
• make, git, ssh, bash, node, and yarn are installed
• Global elm CLI is modified to be called via sysconfcpus as per the workaround discussed in https://github.com/elm/compiler/issues/1473#issuecomment-245704142.
  • Since Elm 0.19, we can also use Haskell runtime system option like +RTS -N2
  • However, community tools that indirectly use elm may not support command line option passing, so in this image we keep wrapping global elm CLI with sysconfcpus.
  • Number of cores passed to elm CLI can be customized using N_CORES environment variable. Defaults to 2.
• Included CLI tools:
  • https://github.com/elm/compiler
  • https://github.com/rtfeldman/node-test-runner
