Description

As a product owner, I want to have a setup according to the Architecture ( #1 ), and some documentation for developers and maintainers, so it can be used for testing purposes and production

Criteria

• rollout must be non-interactive
• single cluster server instance
• all steps can be reproduced in a local setup
• configuration code and scripts are provided
• minimum requirements (for testing) are provided

Additional information

• basically a plain "code-only" deployment of k3s
