Adding a New Service to the Mesh

You built the user profile service and now you need to deploy it into the service mesh.

Deploy Application

Navigate to the workshop directory:
cd $HOME/openshift-microservices/deployment/workshop

The deployment file 'userprofile-deploy-all.yaml' was created for you to deploy the application. The file creates the user profile service and an accompanying PostgreSQL database. Similar to the other source files, an annotation '' was added to tell Istio to inject a sidecar proxy and add this to the mesh.

Verify the annotation in the 'userprofile' file:
cat ./openshift-configuration/userprofile-deploy-all.yaml | grep -B 1


	annotations: "true"
    annotations: "true"

The annotation appears twice for the userprofile and PostgreSQL services.

Before deploying the service, you need a reference to the local image you built in the previous lab.

Run the following commands:
USER_PROFILE_IMAGE_URI=$(oc get is userprofile -o jsonpath='{.status.dockerImageRepository}{"\n"}')

Output (sample):

Deploy the service using this image URI:
sed "s|%USER_PROFILE_IMAGE_URI%|$USER_PROFILE_IMAGE_URI|" ./openshift-configuration/userprofile-deploy-all.yaml | oc create -f -
Watch the deployment of the user profile:
oc get pods -l deploymentconfig=userprofile --watch

The userprofile service may error and restart if the PostgreSQL pod is not running yet.


userprofile-xxxxxxxxxx-xxxxx              2/2     Running		    0          2m55s

Similar to the other microservices, the user profile services run the application and the Istio proxy.

Print the containers in the 'userprofile' pod:
oc get pods -l deploymentconfig=userprofile -o jsonpath='{.items[*].spec.containers[*].name}{"\n"}'


userprofile istio-proxy

Access Application

The user profile service is deployed! Let's test this in the browser.

Navigate to the 'Profile' section in the header.

If you lost the URL, you can retrieve it via:


You should see the following:

Congratulations, you deployed the user profile service and added it to the service mesh!
