Palette supports several day 2 operations to manage the end-to-end lifecycle of the Kubernetes clusters launched through Palette On-Premises Enterprise Mode. It provides several capabilities across clusters to keep your clusters secure, compliant, up-to-date, and perform ongoing management operations like backup/restore and cluster migration across Public Cloud Gateway (PCGs).
Palette enables PCG migration to route the traffic between PCGs to ensure uninterrupted PCG service availability. If a PCG goes unhealthy, it can be deleted after migrating the clusters launched through that PCG to another healthy PCG. This ensures that cluster operations such as deletion are carried out without interruption.
The possible conditions of PCG migration are:
- Unhealthy PCG to healthy PCG
- Healthy PCG to healthy PCG
To migrate the traffic from a PCG:
- Log in as Tenant Admin to the Palette Console.
- From the Tenant Settings, go to the Private Cloud Gateways tab to list all PCGs.
- Click the 'Kebab' menu (three-dot elipsis) towards the PCG to be migrated to see the drop-down option of Migrate.
- Click the Migrate option to open the wizard to select your destination PCG.
- The wizard will display the drop-down list of all healthy PCGs to which traffic can be migrated. Select the PCG of your choice from the drop-down.
- Confirm the migration operation to get a UI confirmation of the successful migration.
- Once the migration is completed, the unhealthy/source PCG can be deleted successfully. Clear the residual resources manually to complete the deletion process.
- The Audit Logs gives the migration update.
