To install opencruise, you need to ensure certificate manager is installed. 


kubectl apply -f https://github.com/cert-manager/cert-manager/releases/download/v1.13.3/cert-manager.yaml


Next, we install openKruise


# Firstly add openkruise charts repository if you haven't do this.

$ helm repo add openkruise https://openkruise.github.io/charts/

# [Optional]

$ helm repo update

# Install the latest version.

$ helm install kruise openkruise/kruise --version 1.5.2


When you do a kubectl get pod -A, you should be able to see there's pod running certificate manager and openKruise.
