How to create a helm chart to deploy multiple applications using the same value.yaml file
I'm trying to deploy
an HTTPD instance and a couch db instance using the same values.yaml file
Is there a default document that can help me understand how to deploy two instances and there services using the same values.yaml file?
Anyone with a sample helm directory with multiple deployments and services created?
Answer
You need to put both services into one helm chart. So they will use only one same values.yaml.
As a sample, I suggest you to look to stable/prometheus helm chart. Right now it has five separated services:
