☂️ Umbrella chart is evil

Helmwave is only what you actually need.

Why is Umbrella chart evil?

  • You must keep extra chart.
  • You have new layer for conventional values.
  • Umbrella chart doesn't provide you environments separation.
  • When sub-chart is modified, you need to fix it twice.

Suppose that you need to describe the next architecture.

graph LR frontend --> api --> rabbitmq & minio_s3 consumer --> rabbitmq & minio_s3 & postgresql
If you don't see a graph, please reload the page.

Example of helmwave.yml for this architecture.
