Adding packages to buildslaves

Prerequisites

Requirements

• Ansible
• buildserver-setuproutine repository
• SSH root-access to the docker host running the buildslave(s) in question

Suggestions

• Understand how the buildserver setup routine works
• SSH root-access via key authentication

Example - Adding 'sys-apps/dtc'

1. Gain access to the buildserver_setup repository

2. Edit roles/docker_buildslave/templates/Dockerfile.j2

3. Add a RUN instruction per package that should be added

   29 RUN \ 30 {% set package="sys-apps/dtc" %} 31 emerge --autounmask-write=y {{ package }}; \ 32 etc-update --automode -5 && \ 33 emerge -u {{ package }} && \ 34 rm -Rf /usr/portage/distfiles/*

4. Connect to the docker host running the buildslave

5. Identify and verify the buildslave containers that have to be rebuilt

   $ docker ps -f name=".*buildslave_[^_]*\..*" -f status=running

6. Stop the buildslave containers

   $ docker ps -f name=".*buildslave_[^_]*\..*" -f status=running -q | xargs docker stop | xargs docker rm

7. Delete the buildslaves images, without their history

   $ docker images | grep -e ".*buildslave-[^-]*\..*" | grep -oE "[[:alnum:]]{12}" | xargs docker rmi --no-prune

8. Comment the rootfs roles in the buildslaves.yml playbook for every architecture

   23 - role: docker_buildslave 24 # - role: docker_buildslave_rootfs

9. Run ansible-playbook

   $ ansible-playbook -i hosts buildslaves.yml --tags all

10. Uncomment the rootfs roles in the buildslaves.yml playbook for every architecture

    23 - role: docker_buildslave 24 - role: docker_buildslave_rootfs
