Test Argo Rollouts

Prerequisite

1. Get access to a Kubernetes cluster
2. Install Argo Rollouts following the instructions. Be sure to install the CLI as well
3. Install Ambassador Edge stack following the instructions

Make a rollout canary release

Open a second terminal and watch the canary

kubectl argo rollouts get rollout demo-app -n demo -w

Edit file rollout.yaml and change line kostiscodefresh/summer-of-k8s-app:v1 to kostiscodefresh/summer-of-k8s-app:v2

Deploy the second version

kubectl apply -f rollout.yaml -n demo

See the canary status at the second terminal. It should be at 30%. Take a screenshot to submit later in the evaluation phase.

If you also visit the application again you should see some boxes with the new version Promote the canary to 60% with

kubectl argo rollouts promote demo-app -n demo

Check the dashboard and terminal again

Promote the canary two more times to reach 100%

kubectl argo rollouts promote demo-app -n demo

Now the old version is no longer present
