Part 4
4 chapters
Multi-service applications
Kafka on Strimzi, the notification service, umbrella charts, library charts and starters.
Chapter 15
Kafka and the notification service
Add a Strimzi Kafka cluster as a chart of custom resources and a second application chart that consumes the shipment.dispatched event.
Chapter 16
Umbrella charts
Combine the services, the database and Kafka into one release with aliases, conditions, tags, global values and import-values, and learn where an umbrella cannot order things.
Chapter 17
Library charts
Move the helpers and templates the service charts copy into a pc-lib library chart, and prove the refactor by diffing rendered manifests.
Chapter 18
Starters and golden paths
Scaffold a new service chart from a pc-fastapi starter with helm create --starter, handle the rewritten Chart.yaml, and see the starter as one step of a golden path.
