Samba Bootstrap
A pure python3 module with CLI to bootstrap Samba envs for multiple distributions.
Features
- manage Samba dependencies list for multiple distributions
- render dependencies package list to boostrap shell scripts(apt, yum and dnf)
- render Vagrantfile to provision vitual machines with bootstrap scripts
- render Dockerfile to build docker images with bootstrap scripts
- build/tag/push docker images
Supported Distributions
deb: Debian 7|8|9|10, Ubuntu 1404|1604|1804 rpm: CentOS 6|7, Fedora 28|29, openSUSE Leap 15.0|15.1
Easy to add more.
Usage
Render files:
bootstrap/template.py --render
Files are rendered into bootstrap/generated-dists directory in current dir.
It also generates bootstrap/sha1sum.txt and prints out the sha1sum of the
current code/configuration.
Just calculate the sha1sum for consistency checks:
bootstrap/template.py --sha1sum
The checksum needs to be added as SAMBA_CI_CONTAINER_TAG in
the toplevel .gitlab-ci.yml file.
User Stories
As a gitlab-ci user, I can use this tool to build new CI docker images:
After committing the result of calling bootstrap/template.py --render
and updating SAMBA_CI_CONTAINER_TAG in .gitlab-ci.yml, you can push
The branch to git@gitlab.com:samba-team/devel/samba.git using:
git push -o ci.skip git@gitlab.com:samba-team/devel/samba.git ...
The -o ci.skip option means gitlab won't start a pipeline
for the just pushed branch.
Instead you would start a custom pipeline at:
https://gitlab.com/samba-team/devel/samba/pipelines/new
But you need to pass SAMBA_CI_REBUILD_IMAGES=yes as environment
variable. It means the pipeline runs the 'images' stage and builds
the new container images for all supported distributions and
uploads the images into the registry.gitlab.com/samba-team/devel/samba
container registry.
If you want to try to build images for the (currently) broken
distributions, you would pass SAMBA_CI_REBUILD_BROKEN_IMAGES=yes
in addition to the custom pipeline. Note the images for
the broken distributions are just build, but not uploaded
to the container registry. And any failures in the image
creation is ignored. Once you managed to get success, you should
move from .build_image_template_force_broken to .build_image_template.
And also add a .samba-o3-template job for the new image
in the main .gitlab-ci.yml file.
Over time we'll get a lot of images pushed to the container registry. The approach we're using allows gitlab project maintainers to remove old images! But it is possible to regenerate the images if you have the need to run a gitlab ci pipeline based on an older branch.
As a Samba developer/tester, I can setup a Samba env very quickly.
With Docker:
cd ~/samba git clean -xdf docker login docker pull registry.gitlab.com/samba-team/devel/samba/samba-ci-ubuntu1804:${sha1sum} docker run -it -v $(pwd):/home/samba/samba samba-ci-ubuntu1804:${sha1sum} bash
With podman:
podman run -ti --cap-add=SYS_PTRACE --security-opt seccomp=unconfined registry.gitlab.com/samba-team/devel/samba/samba-ci-ubuntu1804:${sha1sum} bash
With Vagrant:
cd bootstrap/generated-dists/ vagrant up # start all vagrant up debian9 # start one vagrant ssh debian9 vagrant destroy debian9 # destroy one vagrant destroy # destroy all
Or a remote/cloud machine:
scp bootstrap/generated-dists/fedora30/bootstrap.sh USER@IP: ssh USER@IP sudo bash ./bootstrap.sh
