Update our docker images, only support meson and add required CI bits to build the images with Gilab CI
Add a archlinux
docker image on which we run GstValidate tests
Add a allure
alpine based image for test results
Images contain the subprojects repos but nothing built.
The idea is to schedule daily builds of the docker images so they are always up to date and included repos are new enough.
