In the GitHub repository you will find a bunch of YAML files that denote a pretty standard service offering for Firefly III, the Data Importer and an accompanying MySQL database.
You can find more instructions on GitHub.
Note
These instructions aren't very long, and I'm sorry about that. Most stuff is documented on the GitHub page and I just don't know very much about Kubernetes myself. If you feel you can expand this page, please press the edit button next to the title
