Can I have multiple values.yaml files for Helm
Can I have multiple values.yaml files in a Helm chart?
Something like mychart/templates/internalValues.yaml, mychart/templates/customSettings.yaml, etc?
Accessing properties in a values.yaml file can be done by {{ .Values.property1 }}.
How would I reference the properties in these custom values.yaml files?
Answer
Yes, it's possible to have multiple values files with Helm. Just use the --values flag (or -f).
Example:
helm install ./path --values ./internalValues.yaml --values ./customSettings.yaml
You can also pass in a single value using --set.
Example:
helm install ./path --set username=ADMIN --set password=${PASSWORD}
From the official documentation:
There are two ways to pass configuration data during install:
--values (or -f): Specify a YAML file with overrides. This can be specified multiple times and the rightmost file will take precedence
--set (and its variants --set-string and --set-file): Specify overrides on the command line.
If both are used, --set values are merged into --values with higher precedence. Overrides specified with --set are persisted in a configmap. Values that have been --set can be viewed for a given release with helm get values . Values that have been --set can be cleared by running helm upgrade with --reset-values specified.
