CI: Makefile/Docker testing

To test the build on various distro, I'm using docker containers and a Makefile for orchestration.

pros:

  • You are independent of third party CI runner config (e.g. github actions runners or Travis-CI VM images).
  • You can run it locally on your linux system.
  • Most CI provide runner with docker and Makefile installed (e.g. tarvis-ci minimal images.

cons:

  • Only GNU/Linux distro supported.
  • Could take few GiB (~30 GiB for all distro and all languages)
    • ~500MiB OS + C++/CMake tools,
    • ~150 MiB Python,
    • ~400 MiB dotnet-sdk,
    • ~400 MiB java-jdk.

Usage

To get the help simply type:

make

note: you can also use from top directory

make --directory=bazel

Example

For example to test inside an Ubuntu container:

make ubuntu_test

Docker Layers

Dockerfile is splitted in several stages.
