In order to build each image, just cd into the directory and execute make:

% cd dev && make
% cd commit-tests && make

The opentx-dev image is meant to be used in interactive mode:

% cd ~/src/opentx
% docker run -it --rm -v $(pwd):/src opentx-dev bash
root@02157a542d21:/# cd /src

Then you can just do whatever you need to do with your OpenTX source tree (compile, test, whatever).

The opentx-dev image is meant to be run with specific FLAVOR, so you can if the commit tests on Travis would likely pass on github:

% docker run -it --rm -v $(pwd):/src -e FLAVOR=COLORLCD opentx-commit-tests

You can however run them all by using (beware, this is going to be a very long run):

% docker run -it --rm -v $(pwd):/src -e FLAVOR=ALL opentx-commit-tests

The opentx-dev and opentx-commit-tests image are hosted at Docker hub & Github Container Repository for your convenience.

Pulling from Docker hub is as simple as:

% docker pull pafleraf/opentx-dev
% docker pull pafleraf/opentx-commit-tests

Pulling from Github Container Repository uses a slightly longer command:

% docker pull ghcr.io/raphaelcoeffic/opentx-dev
% docker pull ghcr.io/raphaelcoeffic/opentx-commit-tests
