 1. First, update your `devcontainer.json` to forward the local Docker socket and mount the local `.kube` folder in the container so its contents can be reused. From `.devcontainer/devcontainer.json`:
 
     ```json
-    "runArgs": ["-e", "SYNC_LOCALHOST_KUBECONFIG=true",

     If you also want to reuse your Minikube certificates, just add a mount for your local `.minikube` folder as well:
 
     ```json
-    "runArgs": ["-e", "SYNC_LOCALHOST_KUBECONFIG=true",
-        "-v", "/var/run/docker.sock:/var/run/docker.sock",
