9.9.2 Deploy a container image

Task 9.9.2.2: Deploy a container image

As you know from other techlabs, an easy way to create applications in OpenShift is using oc new-app

Let’s create an application for the go-hello-world image that we built before.

oc new-app appuio/go-hello-world --as-deployment-config

--> Found container image 5779c56 (11 days old) from  for "appuio/go-hello-world:latest"

    * This image will be deployed in deployment config "go-hello-world"
    * Port 8080/tcp will be load balanced by service "go-hello-world"
      * Other containers can access this service through the hostname "go-hello-world"

--> Creating resources ...
    deploymentconfig.apps.openshift.io "go-hello-world" created
    service "go-hello-world" created
--> Success
    Application is not exposed. You can expose services to the outside world by executing one or more of the commands below:
     'oc expose svc/go-hello-world'
    Run 'oc status' to view your app.

To access the application from outside OpenShift, a route is needed:

oc create route edge --service=go-hello-world --insecure-policy=Redirect

Run the following command to determine the host of the newly created route.

oc get routes.route.openshift.io go-hello-world -o template --template '{{.spec.host}}{{"\n"}}'

go-hello-world-<username>.techlab.openshift.ch

Now you can test the go-hello-world application over the route.
