But now I'd like to be able to connect to the cluster directly using the `tanzu` and `kubectl` CLI tools. How do I get the appropriate cluster configuration over to my Chromebook? + +The Tanzu CLI actually makes that pretty easy. I just run these commands on my Linux VM to export the `kubeconfig` of my management (`tce-mgmt`) and workload (`tce-work`) clusters to a pair of files: +```shell +tanzu management-cluster kubeconfig get --admin --export-file tce-mgmt-kubeconfig.yaml +tanzu cluster kubeconfig get tce-work --admin --export-file tce-work-kubeconfig.yaml +``` + +I could then use `scp` to pull the files from the VM into my local Linux environment. I then needed to [install `kubectl`](/tanzu-community-edition-k8s-homelab/#kubectl-binary) and the [`tanzu` CLI](/tanzu-community-edition-k8s-homelab/#tanzu-cli) (making sure to also [enable shell auto-completion](/enable-tanzu-cli-auto-completion-bash-zsh/) along the way!), and I could import the configurations locally: + +```shell +❯ tanzu login --kubeconfig tce-mgmt-kubeconfig.yaml --context tce-mgmt-admin@tce-mgmt --name tce-mgmt +✔ successfully logged in to management cluster using the kubeconfig tce-mgmt + +❯ tanzu login --kubeconfig tce-work-kubeconfig.yaml --context tce-work-admin@tce-work --name tce-work +✔ successfully logged in to management cluster using the kubeconfig tce-work +``` + + + + +
