Access local and kubectl-based Logs ¶

Tanzu Community Edition retains logs for management and workload cluster deployment and operation.

Using Local Cluster Logs ¶

Local cluster logs capture the management 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 remain.

Using kubectl-based Cluster Logs ¶

If local cluster logs do not provide sufficient information, 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 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
