Processing helm variables in values file

helm-value-trick.md

You need to use a tpl trick to interpolate the value, since helm variable in values are not processed, you have to update your deployment, for example:

In your values.yaml:

  tag: "{{ .Chart.AppVersion }}"

In your deployment:

  image: "{{ .Values.api.image.repository }}:{{ tpl .Values.api.image.tag . }}"
