HackWeek 2022: Uyuni SUSE Manager Server containerization - uyuni-project/uyuni GitHub Wiki

Logistics

• This is the right place to record progress and plans
• Slack for discussions
• Official HackWeek page for announcements

Objectives

1. have a lot of fun!
2. learn about Kubernetes (specifically k3s)
3. learn about Helm
4. learn about roadblocks in delivering Uyuni as containers

Conventions

• all development happens on the Uyuni server-containers branch
• all new files are to be added in the containers/ directory
• we use Dockerfiles (built with docker build or buildah), locally for now
• we explicitly do not care about traditional clients at least for now

Current plans

1. create a "fat" container with everything needed for a Server

• :green_circle: start from https://gitlab.suse.de/mbologna/sumadocker/-/tree/saltcontainer
  • uyuni server is starting. Instructions on how to deploy in podman are in: https://github.com/uyuni-project/uyuni/tree/containers/containers/srv/uyuni-container
  • An initial attempt to deploy to a k3s cluster are in the file uyuni.yaml
• :white_circle: find out which directories need to be mounted externally. Starting point: HA paper
• :green_circle: add a startup (Python?) script
• :white_circle: test until it breaks!

2. try to slim down the Server container

• :white_circle: carve PostgreSQL out. Try Postgres-in-containers or outside of them
• :white_circle: disable Cobbler. What needs to be done in order to make Cobbler "optional"?
• :white_circle: disable or remove the traditional stack

3. other research

• :white_circle: we will need a solution about commandline tools. Would it be possible to create a UI around them like Rancher does?

What did we learn?
