Waiting for machine to be running, this may take a few minutes.Machine to be running, this may take a few minutes. Disconnected, in the background, waiting for requests and responding to.For this lab, we will use docker machine on Mac system, and create a docker host with virtualbox driver. Setting Docker configuration on the remote daemon.This section includes tips to help you to troubleshoot common problems that you might encounter when installing Tanzu Kubernetes Grid and deploying Tanzu Kubernetes clusters.Found inside Page 13The CRMS consists of a number of persistent daemons which.
![]() Running tkg init on MacOS results in kubectl version error Tanzu Kubernetes Grid UI does not display correctly on Windows Deploying a Tanzu Kubernetes Cluster Times Out, but the Cluster is Created Remove the kind container, replacing unique_ID with the ID provided in the help message. Kubectl delete cluster.cluster.x-k8s.io/ cluster_name -n tkg-system -kubeconfig ~/.kube-tkg/tmp/config- UUID Attempt these methods in the following order of preference.Run kubectl delete to delete the cluster manually.If the deployment of the management cluster fails, the Tanzu Kubernetes Grid CLI provides a help message to inform you of the location of kubeconfig file of the bootstrap cluster, and prompts you to run the following command, replacing UUID with the ID provided in the help message. Remove mac ads cleaner from computer-+Use the tkg get credentials command to add the cluster credentials to your kubeconfig. Docker kill container_IDDeploying a Tanzu Kubernetes Cluster Times Out, but the Cluster is CreatedRunning tkg create cluster fails with a timeout error similar to the following: I0317 11:11:16.658433 clusterclient.go:341] Waiting for resource my-cluster of type *v1alpha3.Cluster to be up and runningError: unable to wait for cluster and get the cluster kubeconfig: error waiting for cluster to be provisioned (this may take a few minutes): cluster control plane is still being initializedDetailed log about the failure can be found at: /var/folders/_9/qrf26vd5629_y5vgxc1vjk440000gp/T/tkg-20200317T111108811762517.logHowever, if you run tkg get cluster, the cluster appears to have been created. Docker ps -aCopy the container ID of the kind cluster and remove it. In AWS, log in to your Amazon EC2 dashboard and delete the objects manually in the console.Kind Cluster Remains after Deleting Management ClusterRunning tkg delete management-cluster removes the management cluster, but fails to delete the local kind cluster from the bootstrap environment.List all running kind clusters and remove the one that looks like tkg-kind-unique_ID kind delete cluster -name tkg-kind-unique_IDList all running clusters and identify the kind cluster. In AWS, use a tool such as aws-nuke with a specific configuration to delete the objects from Amazon EC2. In vSphere, locate the VMs created, power them off and delete them from your system. In Windows search, enter regedit to open the Registry Editor utility. This happens because a Windows registry is set to application/x-css. Tkg delete cluster my-clusterIf tkg delete cluster fails, use kubectl to delete the cluster manually.Tanzu Kubernetes Grid UI does not display correctly on WindowsWhen you run the tkg init -ui command on a Windows system, the UI opens in your default browser, but the graphics and styling are not applied. Kubectl get pods -AIf all of the nodes and pods are running correctly, your Tanzu Kubernetes cluster has been created successfully and you can ignore the error.If the nodes and pods are not running correctly, attempt to delete the cluster. Kubectl get nodesCheck whether all of the pods are up and running. Kubectl config set-context whether the cluster nodes are all in the ready state. Red alert emulator for macTo do so, the SSH key pair that you created when you deployed the management cluster must be available on the machine on which you run the SSH command. Connect to Cluster Nodes with SSHYou can use SSH to connect to individual nodes of management clusters or Tanzu Kubernetes clusters. Run the tkg init -ui command again to relaunch the UI.Running tkg init on Mac OS results in kubectl version errorIf you run the tkg init command on Mac OS with the latest stable version of Docker Desktop, tkg init fails with the error message: Error: : kubectl prerequisites validation failed: kubectl client version v1.15.5 is less than minimum supported kubectl client version 1.17.0This happens because Docker Desktop symlinks kubectl 1.15 into the path.Put a newer version of kubectl in the path before Docker's version. Set the Value to text/css and click OK. Right-click Content Type and select Modify. Run tkg get management-cluster to recreate the. Kube-tkg/config file on the system on which you run tkg commands, you can recover the credentials from the management cluster control plane node. Recover Management Cluster CredentialsIf you have lost the credentials for a management cluster, for example by inadvertently deleting the. Amazon EC2 bastion: ssh bastion_IP_adressBecause the SSH key is present on the system on which you are running the ssh command, no password is required. Amazon EC2 management cluster and Tanzu Kubernetes nodes: ec2-userTo connect to a node by using SSH, run one of the following commands from the machine that you use as the bootstrap environment: vSphere management cluster and Tanzu Kubernetes nodes: capv To use nfs-utils to mount NFS volumes on nodes, deploy new clusters by using the Kubernetes v1.17.6, v1.17.9, v1.18.3, or v1.18.6 base OS images that are supplied with Tanzu Kubernetes Grid v1.1.2 and 1.1.3. In Tanzu Kubernetes Grid 1.1.2 and later, nfs-utils is enabled by default.If you do not require nfs-utils, you can remove it from cluster node VMs. Kube-tkg/config file on the system on which you run tkg commands.Enable or Disable nfs-utils on Photon OS NodesIn Tanzu Kubernetes Grid 1.0 and 1.1.0, nfs-utils was not included by default in the Photon OS base image template from which cluster nodes are created. Copy the cluster name, the cluster user name, the cluster context, and the client certificate data into the. Sudo vi /etc/kubernetes/admin.confThe admin.conf file contains the cluster name, the cluster user name, the cluster context, and the client certificate data. Waiting For Ssh To Be Available... Docker Upgrade The ClustersThe nfs-utils package is installed during the upgrade.To disable nfs-utils on clusters that you deploy with Tanzu Kubernetes Grid 1.1. To enable nfs-utils on clusters that you deployed with Tanzu Kubernetes Grid 1.0 or 1.1.0, upgrade the clusters to use the Kubernetes v1.17.6, v1.17.9, v1.18.3, or v1.18.6 base OS images that are supplied with Tanzu Kubernetes Grid v1.1.2 or 1.1.3.
