kubeconfig Command Reference

In order for a cluster to be used with K10 Multi-Cluster Manager, it must first be bootstrapped. The bootstrapping process can be performed on a single cluster at a time using the Bootstrap command. Alternatively, multiple clusters can be added through the K10 Multi-Cluster Manager interface by uploading a portable kubeconfig.

Using the k10multicluster tool to prepare a portable kubeconfig that can be used to bootstrap multiple clusters is outlined below.

prepare Command

The prepare command uses local Kubernetes credentials to setup a temporary service account and cluster role binding that can be used for bootstrapping. This service account is used to prepare a portable kubeconfig that can be uploaded or pasted into the K10 Multi-Cluster Manager.

The service account created through this process is created in the default namespace and is labeled with k10.kasten.io/purpose=bootstrapping to allow it to be easily identified. The corresponding cluster role bindings are also labeled this way.

prepare Parameters







Name of a context that should be prepared. May be specified multiple times or as a comma-separated list of contexts.

current context



Path to a kubeconfig file.

KUBECONFIG environment variable or ~/.kube/config

The --context flag may be provided multiple times or as a comma-separated list to prepare a kubeconfig for multiple clusters.


Given that the local system already had two contexts: cluster-1 and cluster-2, the following command could be used to prepare a kubeconfig:

$ k10multicluster kubeconfig prepare --context cluster-1 --context cluster-2 | pbcopy
Preparing context cluster-1…
Preparing context cluster-2…

The pbcopy command is used to copy the resulting kubeconfig into the system clipboard on macOS, other platforms may need to substitute this command. This kubeconfig file can then be pasted into the K10 Multi-Cluster Manager to allow some or all of these clusters to be bootstrapped.
