Rollout Example

Here is an example of how to rollout an application with a component of type CloneSet.

Install Kruise

helm install kruise https://github.com/openkruise/kruise/releases/download/v0.9.0/kruise-chart.tgz --set featureGates="PreDownloadImageForInPlaceUpdate=true"

Rollout steps

1. Install CloneSet based workloadDefinition

kubectl apply -f docs/examples/cloneset-rollout/clonesetDefinition.yaml

2. Apply an application for rolling out

kubectl apply -f docs/examples/cloneset-rollout/app-scale.yaml
kubectl apply -f docs/examples/cloneset-rollout/appRollout-scale.yaml

Check the status of the ApplicationRollout and wait for the rollout to complete.

3. Modify the application image and apply

kubectl apply -f docs/examples/cloneset-rollout/app-target.yaml

4. Apply the application rollout that stops at the second batch and mrk the application as normal

kubectl apply -f docs/examples/cloneset-rollout/appRollout-pause.yaml

Check the status of the ApplicationRollout and see the step by step rolling out. This rollout will pause after the second batch.

5. Apply the application rollout that completes the rollout

kubectl apply -f docs/examples/cloneset-rollout/appRollout-finish.yaml

Check the status of the ApplicationRollout and see the rollout completes, and the ApplicationRollout's "Rolling State" becomes rolloutSucceed
