1. Paste the above output from `create-external-cluster-resources.py` into your current shell to allow importing the source data.
2. Run the [import](https://github.com/rook/rook/blob/master/deploy/examples/import-external-cluster.sh) script.
1. The import script in the next step uses the current kubeconfig context by
default. If you want to specify the kubernetes cluster to use without
changing the current context, you can specify the cluster name by setting
the KUBECONTEXT environment variable.
```console
export KUBECONTEXT=hub-cluster
```
1. Run the [import](https://github.com/rook/rook/blob/master/deploy/examples/import-external-cluster.sh) script.
!!! note
If your Rook cluster nodes are running a kernel earlier than or equivalent to 5.4, remove
