  - title: Deploy SERVER
    preamble: |
      In Private, use the `kubectl apply` command to install the
      server.
    commands:
      private:
        - run: kubectl apply -f server/kubernetes.yaml
          output: deployment.apps/server created

  - standard: kubernetes/link_your_sites
  - title: Expose SERVER
    preamble: |
      In Private, use `skupper expose` to expose SERVER on the Skupper
      network.

      Then, in Public, use `kubectl get service/server` to check that
      the service appears after a moment.
    commands:
      private:
        - await_resource: deployment/server
        - run: skupper expose deployment/server --port 8080 --target-port 80
          output: deployment server exposed as server
      public:
        - await_resource: service/server
        - run: kubectl get service/server
          output: |
            NAME     TYPE        CLUSTER-IP     EXTERNAL-IP   PORT(S)    AGE

  - title: Run CLIENT
    preamble: |
      In Public, use `kubectl run` to run CLIENT.
    commands:
      public:
        - await_resource: service/server
        - run: kubectl run client --attach --rm --image docker.io/library/nginx --restart Never -- curl -sf http://server:8080/
          output: |
            OUTPUT
            pod "client" deleted
  - standard: kubernetes/cleaning_up
    commands:
      private:
        - run: skupper delete
        - run: kubectl delete -f server/kubernetes.yaml
      public:
        - run: skupper delete
