helmfile

Deploy Kubernetes Helm Charts

about

Helmfile is a declarative spec for deploying helm charts. It lets you...

• Keep a directory of chart value files and maintain changes in version control.
• Apply CI/CD to configuration changes.
• Periodically sync to avoid skew in environments.

To avoid upgrades for each iteration of helm, the helmfile executable delegates to helm - as a result, helm must be installed.

The default helmfile is charts.yaml:

repositories:
  - name: roboll
    url: http://roboll.io/charts

charts:
  - name: vault                          # helm deployment name
    namespace: vault                     # target namespace
    chart: roboll/vault-secret-manager   # chart reference
    values: [ vault.yaml ]               # value files (--values)
    set:                                 # values (--set)
      - name: address
        value: https://vault.example.com
    env:                                 # values (--set) but value will be pulled from environment variables. Will throw an error if the environment variable is not set.
      - name: db.password
        value: DB_PASSWORD               # $DB_PASSOWRD needs to be set in the calling environment ex: export DB_PASSWORD='password1'
