Access the Tanzu Kubernetes Grid Logs

Tanzu Kubernetes Grid retains logs for management cluster and workload cluster deployment and operation.

See Audit Logging to retrieve audit logs at the Kubernetes API or Linux system level.

Using Local Cluster Logs

Local cluster logs capture the management cluster and workload cluster creation, upgrade, and deletion activity in the ~/.config/tanzu/tkg/logs/CLUSTER-NAME file. These logs can be used to troubleshoot the cluster creation activity and other failures. Successfully deleting a cluster automatically deletes its logs file, but if the delete action fails, the logs file remains and can be reviewed by the user or support team.

Using kubectl-based Cluster Logs

If local cluster logs do not provide sufficient information to monitor deployments or troubleshoot component failure, you can retrieve logs using kubectl as follows:

Access Management Cluster Deployment Logs

To monitor and troubleshoot management cluster deployments, review:

  • The log file listed in the terminal output Logs of the command execution can also be found at…

  • The log from your cloud provider module for Cluster API. Retrieve the most recent one as follows:

    1. Search your tanzu management-cluster create output for Bootstrapper created. Kubeconfig: and copy the kubeconfig file path listed. The file is in ~/.kube-tkg/tmp/.
    2. Run the following, based on your cloud provider:
      • vSphere: kubectl logs deployment.apps/capv-controller-manager -n capv-system manager --kubeconfig </path/to/kubeconfig>
      • Amazon Web Services (AWS): kubectl logs deployment.apps/capa-controller-manager -n capa-system manager --kubeconfig </path/to/kubeconfig>
      • Azure: kubectl logs deployment.apps/capz-controller-manager -n capz-system manager --kubeconfig </path/to/kubeconfig>

Access Workload Cluster Deployments Logs

After running tanzu cluster create, you can monitor the deployment process in the Cluster API logs on the management cluster.

To access these logs, follow the steps below:

  1. Set kubeconfig to your management cluster. For example:

    kubectl config use-context my-management-cluster-admin@my-management-cluster
  2. Run the following:

    • capi logs:

      kubectl logs deployments/capi-controller-manager -n capi-system manager
    • IaaS-specific logs:

      • vSphere: kubectl logs deployments/capv-controller-manager -n capv-system manager
      • AWS: kubectl logs deployments/capa-controller-manager -n capa-system manager
      • Azure: kubectl logs deployments/capz-controller-manager -n capz-system manager
