Private Cluster Setup

Key Features/Components

• Private Cluster: Ensures that the nodes in the cluster are not directly accessible from the internet.
• Network Policies: Enables fine-grained control over inbound and outbound traffic within the cluster.
• Isolation: Provides enhanced security by isolating the cluster from external access.

Step-by-step Instructions or Configuration Details

1. Creating a Private Cluster:

   • Use the following command to create a private cluster in HKE:

     hke cluster create --private true

2. Configuring Network Policies:

   • Define network policies using YAML files and apply them to the cluster.

     # Example Network Policy
     apiVersion: networking.k8s.io/v1
     kind: NetworkPolicy
     metadata:
       name: my-network-policy
     spec:
       podSelector:
         matchLabels:
           role: db
       ingress:
       - from:
         - podSelector:
             matchLabels:
               role: frontend
         ports:
         - protocol: TCP
           port: 3306

Best Practices and Recommendations

• Regularly review and update network policies to maintain a secure environment.
• Implement strong authentication mechanisms for cluster access.
