Docker images for hybris-mobian

This repository contains the required source files to build Docker images for various release engineering tasks (package building, hardware adaptation building, rootfs building, etc...).

These are built in Travis CI and, for the 'master' branch, the build artifacts are pushed automatically into Docker Hub, at the hybrismobian organization.

Currently built images

• build-essential (amd64 and arm64)

Adding a new image template

Image templates must be stored in the root directory of this repository, and must be named as Dockerfile.@template@.in, where @template@ is the template name.

The following strings are replaced:

String	Description	Example (for arm64/hybrismobian/build-essential:bookworm)
%(target_name)s	Sanitized slug of the full target name	arm64_hybrismobian_build_essential_bookworm
%(arch)s	Architecture	arm64
%(namespace)s	Docker namespace	hybrismobian
%(template)s	Template name	build-essential
%(tag)s	Image tag	bookworm

Once a template has been made, you must add the desired docker images ("full target name") to the build matrix into the .travis.yml file:

  # AMD64 (x86_64) image containing toolchains and essential build
  # tools
  - name: amd64/hybrismobian/build-essential:bookworm
    arch: amd64
    <<: *docker_build_template
  # ARM64 (AArch64) image containing toolchains and essential build
  # tools
  - name: arm64/hybrismobian/build-essential:bookworm
    arch: arm64-graviton2
    virt: vm # required to route the job to arm64-graviton2 
    group: edge # required to route the job to arm64-graviton2
    <<: *docker_build_template

In this example, the same template (build-essential) has now specified for both amd64 and arm64 builds.
Be extra sure to include the <<: *docker_build_template part!

Once the build matrix has been updated, build the target Dockerfiles with

make refresh-images

(a recent-ish python interpreter and pyyaml are required).
