3. Flexibility: Kyverno supports both Helm and YAML-based installations, catering to various preferences.

Installing Kyverno Using Helm

Helm, the package manager for Kubernetes, offers a straightforward way to install Kyverno. Follow these steps:

• Add the Kyverno repository:

helm repo add kyverno https://kyverno.github.io/kyverno/ helm repo update

• Install the Kyverno controller:

helm install kyverno kyverno/kyverno --namespace kyverno --create-namespace

• Install Kyverno policies:

helm install kyverno-policies kyverno/kyverno-policies --namespace kyverno

Installing Kyverno Using YAML Manifests

For those who prefer YAML-based installations, Kyverno offers a simple one-line command:

kubectl create -f https://raw.githubusercontent.com/kyverno/kyverno/main/config/install.yaml

Verifying Your Kyverno Installation

After installation, it’s crucial to ensure Kyverno is running correctly. Here’s how:

1. Check the status of Kyverno pods:

kubectl get pods -n kyverno

1. If you encounter issues, investigate further:

• View detailed pod information:

kubectl describe pod <kyverno-pod-name> -n kyverno

• Check Kyverno logs:

kubectl logs -l app.kubernetes.io/name=kyverno -n kyverno

Troubleshooting Kyverno Installation

If you face any challenges during the installation process, consider these tips:

1. Ensure your Kubernetes cluster meets Kyverno’s minimum requirements.

2. Verify that you have the necessary permissions to create resources in the kyverno namespace.

3. Check for any network policies that might be blocking communication between Kyverno and the Kubernetes API server.
