Governance Platform

Air-Gapped Install

Use an air-gapped install when the cluster cannot pull charts or images from public or hosted registries.

Preparation

Section titled “Preparation”
  1. Obtain the release package and release manifest.
  2. Mirror every runtime image listed in the manifest to the customer-approved registry.
  3. Preserve image tags and digests from the manifest.
  4. Package or mirror the Helm chart and dependencies for the restricted environment.
  5. Prepare registry credentials, image pull secrets, values, and platform secrets.

Install Flow

Section titled “Install Flow”

Install the Governance Platform chart from the approved internal source and override image registry values so every component pulls from the mirrored registry.

Verify that the cluster never needs to reach an external registry during install or restart.

Validation Checks

Section titled “Validation Checks”
  • All pods pull images from the mirrored registry.
  • Chart version and image digests match the release manifest.
  • Sign-in, project access, attachments, reports, indicators, and certificates work according to the rollout plan.

Support Notes

Section titled “Support Notes”

Keep the mirrored image list, chart package, values file, and validation evidence with the release records. They are needed for rollback, support, and disaster recovery.
