# 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 bootstrap shell scripts(apt, yum and dnf)
- render Vagrantfile to provision virtual machines with bootstrap scripts
- render Dockerfile to build docker images with bootstrap scripts
- build/tag/push docker images
## Supported Distributions
deb: Debian 10, Ubuntu 1604|1804|2004
rpm: CentOS 7|8, Fedora 33|34, openSUSE Leap 15.1|15.2
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-main.yml file.
NOTE: Remember to remove any files not tracked by git from the bootstrap
directory before running bootstrap/template.py.
git clean -dfx bootstrap
Otherwise the files will affect the checksum but because they are not
checked in and won't be pushed to CI system the checksum calculated there
won't match.
## 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.
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.
You can push by specifying the variable (note multiple -o options are allowed,
see https://docs.gitlab.com/ee/user/project/push_options.html):
`git push -o ci.variable='SAMBA_CI_REBUILD_IMAGES=yes' git@gitlab.com:samba-team/devel/samba.git ...`
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 debian10 # start one
vagrant ssh debian10
vagrant destroy debian10 # destroy one
vagrant destroy # destroy all
Or a remote/cloud machine:
scp bootstrap/generated-dists/fedora33/bootstrap.sh USER@IP:
ssh USER@IP
sudo bash ./bootstrap.sh
