Add the linkerd CLI to your path with:

  export PATH=$PATH:/home/code/.linkerd2/bin

Now run:

  # install the GatewayAPI CRDs
  kubectl apply -f https://github.com/kubernetes-sigs/gateway-api/releases/download/v1.2.1/standard-install.yaml

  linkerd check --pre                         # validate that Linkerd can be installed
  linkerd install --crds | kubectl apply -f - # install the Linkerd CRDs
  linkerd install | kubectl apply -f -        # install the control plane into the 'linkerd' namespace
  linkerd check                               # validate everything worked!

You can also obtain observability features by installing the viz extension:

  linkerd viz install | kubectl apply -f -  # install the viz extension into the 'linkerd-viz' namespace
  linkerd viz check                         # validate the extension works!
  linkerd viz dashboard                     # launch the dashboard
