Deploy the F5 Hello World Container

All of the following commands and yaml files are contained within the "f5-kube-demo" github repo.

$ git clone https://github.com/vtog/f5-kube-demo.git

Basic f5-hello-world application deployment commands:

1. Create f5 hello world kubernetes deployment

   $ kubectl create -f f5-hello-world-deployment.yaml
   

   apiVersion: extensions/v1beta1
   kind: Deployment
   metadata:
     name: f5-hello-world 
   spec:
     replicas: 2
     template:
       metadata:
         labels:
           run: f5-hello-world
       spec:
         containers:
         - name: f5-hello-world
           image: "f5devcentral/f5-hello-world"
           imagePullPolicy: IfNotPresent
           ports:
           - containerPort: 8080
             protocol: TCP
   

2. Create f5 hello world kubernetes configmap

   $ kubectl create -f f5-hello-world-configmap.yaml
   

   apiVersion: v1
   kind: ConfigMap
   metadata:
     name: f5-hello-world
     namespace: default
     labels:
       f5type: virtual-server
   data:
     schema: "f5schemadb://bigip-virtual-server_v0.1.7.json"
     data: |
       {
         "virtualServer": {
           "frontend": {
             "balance": "round-robin",
             "mode": "http",
             "partition": "kubernetes",
             "virtualAddress": {
               "bindAddr": "10.1.10.81",
               "port": 80
             }
           },
           "backend": {
             "serviceName": "f5-hello-world",
             "servicePort": 8080,
             "healthMonitors": [{
               "interval": 5,
               "protocol": "http",
               "send": "HEAD / HTTP/1.0\r\n\r\n",
               "timeout": 16
             }]
           }
         }
       }
   

3. Create f5 hello world kubernetes service

   "type" needs to be set based on the mode configured for the f5 / kubernetes container connector. Edit the yaml file and change type to "NodePort" or "ClusterIP". The example below shows "NodePort"

   $ kubectl create -f f5-hello-world-service.yaml
   

   apiVersion: v1
   kind: Service
   metadata:
     name: f5-hello-world
     labels:
       run: f5-hello-world
   spec:
     ports:
     - port: 8080
       protocol: TCP
       targetPort: 8080
     type: NodePort
     selector:
       run: f5-hello-world
   

4. Verify f5-hello-world container is up and running

   $ kubectl get pods -o wide
   goto http://10.1.10.81
   

5. Add or remove resources to the application. Edit the yaml file and change the desired number of replicas

   $ vim f5-hello-world-configmap-modify.yaml
   $ kubectl apply -f f5-hello-world-configmap-modify.yaml
