Can I have multiple values.yaml files for Helm

Question

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?

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.
