+# 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 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.
+
+## 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
