EDIB packaging test

Elixir Docker Image Packager test setup for different CI services

Links

• About EDIB
• mix-edib
• EDIB tool (docker image)

Travis CI

Notes

• --rm seems to be okay to use.
• Must install Elixir via Ubuntu package (language: elixir does not work).
• Use language: ruby instead.
• Also do not forget to set sudo: required, because we install OS packages.

See: http://docs.travis-ci.com/user/docker/

---

CircleCI

Notes

• docker run: Never use --rm, it always fails.
• Only runs successfully with Docker 1.10+

See: https://circleci.com/docs/docker

Wercker

Notes

• Getting docker running in the docker container ... is an impossible thing.
• Docker-in-Docker seems not working for this service.
• Perhaps the outer container is missing the --privileged flag.

See: http://devcenter.wercker.com/docs/pipelines/stacks.html

---

Shippable

Notes

• Similar to Travis (can even use their .travis.yml), but seems not to support running docker itself (in CI step).
• Would perhaps need a Docker-in-Docker approach. (within Pre-CI/Post-CI workflow)

See: http://docs.shippable.com/docker_build/

Other service?

Tell me which one to try.

It must run docker, of course!
