Helm conditionally install subchart

Question

Is there a way to conditionally install a helm subchart based on global values.yaml? I\'ve all my internal services and components as subcharts, and one of them is a message

Answer 1

I've found out the answer:

In requirements.yaml, add:

dependencies:
- name: api
  condition: api.enabled
- name: messagequeue
  condition: messagequeue.enabled

and in values.yaml, add

api:
  enabled: true    
messagequeue:
  enabled: false

Now during installation, pass the values to enabled or disable the messagequeue as follows:

helm install --dry-run --debug website\ --set messagequeue.enabled=true

or

helm install --dry-run --debug website\ --set messagequeue.enabled=false

Answer 2

I would propose this (ugly) workaround as answer borrowed from @sgandon: https://github.com/helm/helm/issues/3742#issuecomment-383095917

dependencies: - name: mobi-postgresql version: 1.0.1 repository: "@mobi" alias: postgresql - name: oraclepdb version: 0.0.1 repository: "file://subcharts/oraclepdb" condition: oraclepdb.enabled

Then you can use the practice Chart dependencies to manage subcharts as dependencies via helm dep update and helm dep build.

It's not beautiful as long as this bug is not fixed.
