Using the Shared-Secrets chart

The shared-secrets sub-chart is responsible for provisioning a variety of secrets used across the installation, unless otherwise manually specified. This includes:

  1. Initial root password
  2. Self-signed TLS certificates for all public services: GitLab, Minio, and Registry
  3. Registry authentication certificates
  4. Minio, Registry, GitLab Shell, and Gitaly secrets
  5. Redis and Postgres passwords
  6. SSH host keys

Disable functionality

Some users may wish to explicitly disable the functionality provided by this sub-chart. To do this, we have provided the enabled flag as a boolean, defaulting to true.

To disable the chart, pass --set shared-secrets.enabled=false, or pass the following in a YAML via the -f flag to helm:

  enabled: false
Note: If you disable this sub-chart, you must manually create all secrets, and provide all necessary secret content. See installation/secrets for further details.
