Module peering

The peering module establishes a trusted connection between Deckhouse Platform clusters. A connection between two clusters is called a peering. Peerings are used by platform modules: virtualization migrates virtual machines to another cluster, istio joins clusters into a service mesh, managed-postgres places a database replica in another cluster.

Key features

The module provides the following features:

• Peering by mutual consent. A peering is established only with the consent of the administrators of both clusters: one creates an invitation, the other connects with it.
• Revoking a peering. Either administrator can unilaterally revoke a peering.
• Access controlled by each side. The administrator of each cluster defines which module capabilities are available to a connected cluster.
• Project pairing. Projects with the same name in connected clusters are paired automatically.

Establishing a peering is described in the administrator guide.
