The following snippet shows an example values.yaml file for a Helm installation of CircleCI server in an air-gapped environment.

Resources

The chart assumes an environment with the following resources:

  • A K3s cluster for the installation of the Helm chart

  • MetalLB pre-configued on the K3s cluster for ingress

  • A private docker registry at docker.internal.example.com running on port 5000 with no TLS encryption

  • A Nomad instance with mTLS disabled

  • A MinIO instance running at minio.internal.example.com, with its API listening on port 9000, and no TLS

  • A TLS certificate issued for both domains server.internal.example.com and *.server.internal.example.com`.

For more information about specific values, see the standard installation documentation, starting with Phase 2 - Core services.
