Clusters

Cluster is a concept introduced in tsuru-server 1.2 and allows registering existing clusters of external provisioners in tsuru. Currently, external clusters can be registered to kubernetes and swarm provisioners.

Clusters can either have a default flag or have multiple assigned pool. tsuru will use this information to decide which cluster will be used when interacting with a pool.

When a cluster is registered in tsuru it means that it becomes visible to the provisioner as a source of information on nodes and units for applications. It also become available as a possible destination for the creation of the resources necessary to deploy or scale an application. See provisioners for details on which resources are created for each provisioner.

To manipulate clusters the client commands tsuru cluster-add, tsuru cluster-list, tsuru cluster-update and tsuru cluster-remove can be used. You can find more information about them in the client documentation.
