Visit UI @ http://127.0.0.1:8080

CLI cmd tanzu management-cluster create mgmtcluster01 --file /home/shaunhess/.config/tanzu/tkg/clusterconfigs/8j4fjxjcwi.yaml -v 6

5. Validate management cluster is started

tanzu management-cluster get

To delete management cluster tanzu management-cluster delete

5. Capture management cluster kubeconfig

tanzu management-cluster kubeconfig get <MGMT-CLUSTER-NAME> --admin

6. Set your kubectl context to the management cluster.

kubectl config use-context <MGMT-CLUSTER-NAME>-admin@<MGMT-CLUSTER-NAME>

7. Get nodes

kubectl get nodes

8. Create workload cluster

tanzu cluster create <WORKLOAD-CLUSTER-NAME> --plan dev

Validate cluster started tanzu cluster list

9. Capture the workload cluster’s kubeconfig

tanzu cluster kubeconfig get <WORKLOAD-CLUSTER-NAME> --admin

11. Get pods in cluster

kubectl get pods -A

12. Get services in cluster

kubectl get svc -A

Managed Cluster

Integrate into preferred infrastructure

• CNI - Container Network Interface
• CPI - Cloud Provider Interface - CSI
• Container Storage Interface (Native storage interface for persistent storage)

East <--> West Traffic (Pod container communication)

• Antrea (VMware)
• Calico
• Multus (Multi-homed pods; pods with multiple network interfaces)

North <--> South Traffic (Layer 4 - External Traffic)

• kube-vip
• NSX

Consistently Deploy Apps Across Any Infrastructure

Secure End-to-End Cloud Native Operations

Visibility Into Cluster Operations and Apps
