Introduction ------------ This repository contains the dockerfiles used by Linaro CI. Contributing ------------ If you want to contribute changes, you can send Gerrit merge requests at https://review.linaro.org/#/q/project:ci/dockerfiles TCWG images ----------- Docker images used by the TCWG team are generated slightly differently from the other ones. The source files describing the images contents are stored under tcwg-base, in nested directories where nesting shows images dependencies. For instance, tcwg-build type of images depend on tcwg-base. If you want to (re)build locally a TCWG image after updating its Dockerfile.in or its build.sh, go to the directory whose name fully describes the image. For instance xenial-arm64-tcwg-base/xenial-arm64-tcwg-build, and run ./build.sh from there to rebuild the xenial-arm64-tcwg-build image. TCWG's Dockerfiles in DISTRO-ARCH-tcwg-base/* directories are generated from Dockerfile.in templates in respective tcwg-base/* directories. Run tcwg-base/generate-dockerfiles.sh (without parameters) whenever you change any of Dockerfile.in templates -- this will update all affected Dockerfiles. Once Dockerfiles are regenerated, you should test your change locally by building the image. For this go to image's directory and run "./build.sh". "./build.sh" script uses name of current directory to determine distro version and other parameters, so it's important to run "./build.sh" from its own directory. Note that "./build.sh" will first re-build all images that current image is derived from. E.g., *-tcwg-dev image will first re-build respective *-tcwg-base image -- this can take a lot of time for the first run, but, once cache is populated, re-builds are very quick.
