Debugging applications

Now that we have a basic understanding of how to monitor deployments, we can start seeing how we can debug issues with deployments.

In this section, we will introduce common errors and determine how to debug and fix them.

If not done already, run the following command:

kubectl create -f guestbook-all-in-one.yaml

After sometime, the services should be up and running.

Image Pull errors

In this section, we are going to introduce image pull errors by setting the image tag value to a non-existent one.

Run the following command on Azure Cloud Shell:

kubectl edit deployment/frontend

Next, change the image tag from v3 to v_non_existent by running the following commands:

image: gcr.io/google-samples/gb-frontend...
