A Helm chart with cp-schema-registry for Kubernetes
The original Helm chart for Confluent Schema Registry has been deprecated, and over time it became too bulky and outdated. That's why I've created a new, lighter, and more up-to-date Helm chart. This new chart is more streamlined and easier to customize.
Some of the key changes include:
- Configurations that are compatible with the latest Kubernetes features
- Easier setup, with more modular and flexible options
