With the CLI installed and signed in, this command provisions a single node cluster on your Mac, applies the scenario setup and prints the task below.

goldenkube start cka-wkl-002

Task

The task text exactly as the CLI shows it. Solve it on the cluster, then run goldenkube submit.

In namespace "apps" a Deployment named "store" is running nginx:1.26 with 4 replicas. Update it to image nginx:1.27 using a rolling update (do not delete and recreate the Deployment). When you are done, all 4 pods must be Ready and running the new image.
