Create Helm Charts for CoMPAS Kubernetes Deployment

[david-monichi]

User Story

As a DevOps Engineer

I want to be able to create configurations

So that CoMPAS can be deployed on various stages on Kubernetes clusters

Acceptance criteria

• For all services mentioned in the docker-compose configuration an equivalent helm chart exists
• A simple dev stage can be deployed out of the box via helm files (Kubernetes cluster must already exist)

@trusz @clepski here it is

After a short sync with @clepski we came up with following structural proposal:

  charts/
      cim-mapping
      keycloak
      open-scd
      ...
  stages/
      local/
          opens-scd.yaml
          keycloak.yaml
          values.yaml
      helmfile.yaml

• In directory charts/ we will hold all service charts which will be reusable by any project.
• In directory an example configuration will be provided which contains all configurations for a local cluster. Similar solution can then be applied for various customer stages.

After discussing the current solution (on 12.2.2025 in https://lf-energy.atlassian.net/wiki/spaces/SHP/pages/190349324/43the+meeting+12+February+2025) we agreed on using an Operator for Keycloak
