Create a project:

oc new-project course-training-<number> --description="csc_project: xxxx"

The project should be now visible on the web console and it should get listed with oc projects command.

```bash $ oc projects You have one project on this server: “course-rahti-".

Using project “course-rahti-" on server "https://rahti.csc.fi:8443".

DeploymentConfig

Create a DeploymentConfig file that will spawn a pod running image openshift/hello-openshift. Name it hello-openshift and label it app: hello-openshift. Apply the same label app: hello-openshift to the pods to be spawned as well.

dc.yaml:

apiVersion: apps.openshift.io/v1
kind: DeploymentConfig
metadata:
  labels:
    app: hello-openshift
  name: hello-openshift
spec:
  replicas: 1
  selector:
    app: hello-openshift
  template:
    metadata:
      labels:
        app: hello-openshift
    spec:
      containers:
      - image: openshift/hello-openshift:latest
        name: hello-openshift
        ports:
        - containerPort: 8080

oc create -f dc.yaml

Service

Create a Service object file that will redirect traffic internally to the pod.

service.yaml:

apiVersion: v1
kind: Service
metadata:
  labels:
    app: hello-openshift
  name: hello-openshift
spec:
  selector:
    app: hello-openshift # Must match the DeploymentConfig
  ports:
  - name: 8080-tcp
    port: 8080
    protocol: TCP
    targetPort: 8080
  - name: 8888-tcp
    port: 8888
    protocol: TCP
    targetPort: 8888

oc create -f service.yaml

Route

Create a Route file and expose the Service to internet at ‘hello-openshift-xx.rahtiapp.fi’. (Where ‘xx’ is the number of the training account you are holding).

route.yaml:

apiVersion: route.openshift.io/v1
kind: Route
metadata:
  labels:
    app: hello-openshift
  name: hello-openshift
spec:
  host: hello-openshift-tutorial.rahtiapp.fi # Change the name
  port:
    targetPort: 8080-tcp # Must match your service port name
  tls:
    termination: edge
    insecureEdgeTerminationPolicy: Redirect
  to:
    kind: Service
    name: hello-openshift # Must match your service name

oc create -f route.yaml

Accessing the application

Now you deployed your Route, you can access the application through the address https://hello-rahti-xx.rahtiapp.fi and you should see “Hello Openshift!”

Cleanup

oc delete all -l app=hello-openshift

oc delete -f dc.yaml -f service.yaml -f route.yaml
