Breaking Changes

TKGI v1.12.0 has the following breaking changes:

• Fluent Bit has been upgraded to Fluent Bit v1.5.7:

  • Previous versions of TKGI have used Fluent Bit v1.3.4. For information on the differences between the Fluent Bit v1.3.4 and v1.5.7 releases, see Upgrade Notes in the Fluent Bit documentation.
    
  • By default, Fluent Bit v1.5.7 limits the size of Kubernetes log metadata to 32 KB. For more information, see Some Kubernetes Logs Are Not Forwarded after Upgrading in the TKGI v1.12.0 Known Issues below.
    

• TKGI uses a new sink-resources image path:
  
  With TKGI v1.12.0 the sink-resources image path has changed from epks-docker-local.artifactory.eng.vmware.com/oratos/ to gcr.io/cf-pks-releng-environments/oratos/.
  
  

• Newly created clusters use the containerd runtime by default instead of the Docker runtime:
  
  The logging prefix on containerd runtime cluster log entries is different than the prefix on Docker runtime cluster log entries. Cluster log entries read by Fluent Bit are prefixed:

  • TIMESTAMP (stdout|stderr) [EP] in Docker runtime cluster output.
  • TIMESTAMP stdout F in containerd runtime cluster output.
    

Features

TKGI v1.12.0 has the following features and enhancements:

Supports NSX-T Policy API

(Beta) Supports NSX-T Policy API for new installations. See Considerations for Using the NSX-T Policy API with TKGI and Networking in Installing Tanzu Kubernetes Grid Integrated Edition on vSphere with NSX-T.

Warning: Support for the NSX-T Policy API is currently in beta and is intended for evaluation and test purposes only. Do not use this feature in a production environment.

Supports Cluster Cert Rotation Using the CLI

Supports Kubernetes cluster certificate rotation using the TKGI CLI. See Rotate Kubernetes Cluster Certificates.

Supports Persistent Redirect URIs

TKGI MC Unable to Manage TKGI after Restoring the TKGI Control Plane from Backup

Symptom

After you restore Ops Manager and the TKGI API VM from backup, TKGI functions normally, but your TKGI MC tabs include the following error: “…product ‘pivotal-container service’ is not deployed…”.

Explanation

TKGI MC is associated with an Ops Manager with a specific name. If you rename Ops Manager with a new name while restoring, your TKGI MC will not recognize the restored Ops Manager and cannot manage it.

Kubernetes Pods on NSX-T Become Stuck in a Creating State

Symptom

The pods in your TKGI Kubernetes clusters on NSX-T become stuck in a creating state. The connections between nsx-node-agent and hyperbus repeatedly close, log Couldn't connect to 'tcp://...' (error: 111-Connection refused), and have a status of COMMUNICATION_ERROR.

Explanation

For information and workaround steps for this Known Issue, see Issue 2795268: Connection between nsx-node-agent and hyperbus flips and Kubernetes pod is stuck at creating state in NSX Container Plugin 3.1.2 Release Notes in the VMware documentation.

Pods Stop After Upgrading From NSX-T v3.0.2 to v3.1.0 on vSphere 7.0 and 7.0.1

Symptom

Your TKGI-provisioned Pods stop after upgrading from NSX-T v3.0.2 to NSX-T v3.1.0 on vSphere 7.0 and 7.0.1.

Explanation

For information, see Issue 2603550: Some VMs are vMotioned and lose network connectivity during UA nodes upgrade in the VMware NSX-T Data Center 3.1.1 Release Notes.

Workaround

To avoid the loss of network connectivity during UA node upgrade, ensure DRS is set to manual mode during your upgrade from NSX-T v3.0.2 to v3.1.0.

If you upgraded to NSX-T v3.1.0 with DRS in automation mode, run the following on the affected Pods’ control plane VMs to restore Pod connectivity:

monit restart ncp

For more information about upgrading NSX-T v3.0.2 to NSX-T v3.1.0, see Upgrade NSX-T Data Center to v3.0 or v3.1.

Error: Could Not Execute “Apply-Changes” in Azure Environment

Symptom

After clicking Apply Changes on the TKGI tile in an Azure environment, you experience an error ’…could not execute “apply-changes”…’ with either of the following descriptions:

• {“errors”:{“base”:[“undefined method 'location’ for nil:NilClass”]}}
• FailedError.new(“Resource Groups in region ’#{location}’ do not support Availability Zones”))

For example:

Explanation

The Azure CPI endpoint used by Ops Manager has been changed and your installed version of Ops Manager is not compatible with the new endpoint.

Workaround

Run the following Ops Manager CLI command:

om --skip-ssl-validation --username USERNAME --password PASSWORD --target https://OPSMAN-API curl --silent --path /api/v0/staged/director/verifiers/install_time/IaasConfigurationVerifier -x PUT -d '{ "enabled": false }'

Where:

• USERNAME is the account to use to run Ops Manager API commands.
• PASSWORD is the password for the account.
• OPSMAN-API is the IP address for the Ops Manager API

For more information, see Error 'undefined method location’ is received when running Apply Change on Azure in the VMware Tanzu Knowledge Base.

VMware vRealize Operations Does Not Support Windows Worker-Based Kubernetes Clusters

VMware vRealize Operations (vROPs) does not support Windows worker-based Kubernetes clusters and cannot be used to manage TKGI-provisioned Windows workers.

TKGI Wavefront Requires Manual Installation for Windows Workers

To monitor Windows-based worker node clusters with a Wavefront collector and proxy, you must first install Wavefront on the clusters manually, using Helm. For instructions, see the Wavefront section of the Monitoring Windows Worker Clusters and Nodes topic.

Pinging Windows Worker Kubernetes Clusters Does Not Work

TKGI-provisioned Windows worker-based Kubernetes clusters inherit a Kubernetes limitation that prevents outbound ICMP communication from workers. As a result, pinging Windows workers does not work.

For information about this limitation, see Limitations > Networking in the Windows in Kubernetes documentation.

Velero Does Not Support Backing Up Stateful Windows Workloads

You can use Velero to back up stateless TKGI-provisioned Windows workers only. You cannot use Velero to back up stateful Windows applications. For more information, see Velero on Windows in Basic Install in the Velero documentation.

Tanzu Mission Control Integration Not Supported on GCP

TKGI on Google Cloud Platform (GCP) does not support Tanzu Mission Control (TMC) integration, which is configured in the Tanzu Kubernetes Grid Integrated Edition tile > the Tanzu Mission Control pane.

If you intend to run TKGI on GCP, skip this pane when configuring the Tanzu Kubernetes Grid Integrated Edition tile.

TMC Data Protection Feature Requires Privileged TKGI Containers

TMC Data Protection feature supports privileged TKGI containers only. For more information, see Plans in the Installing TKGI topic for your IaaS.

Windows Worker Kubernetes Clusters with Group Managed Service Account Do Not Support Compute Profiles

Windows worker-based Kubernetes clusters integrated with group Managed Service Account (gMSA) cannot be managed using compute profiles.

Windows Worker Kubernetes Clusters on Flannel Do Not Support Compute Profiles

On vSphere with NSX-T networking you can use compute profiles with both Linux and Windows worker‑based Kubernetes clusters. On vSphere with Flannel networking, you can apply compute profiles only to Linux clusters.

TKGI CLI Does Not Prevent Reducing the Control Plane Node Count

TKGI CLI does not prevent accidentally reducing a cluster’s control plane node count using a compute profile.

Warning: Reducing a cluster’s control plane node count can destroy the cluster. Do not scale out or scale in existing control plane nodes by reconfiguring the TKGI tile or by using a compute profile. Reducing a cluster’s number of control plane nodes may remove a control plane node and cause the cluster to become inactive.

Windows Cluster Nodes Not Deleted After VM Deleted

Symptom

After you delete a VM using the management console of your infrastructure provider, you notice a Windows worker node that had been on that VM is now in a notReady state.

Solution

1. To identify the leftover node:

   kubectl get no -o wide
   

2. Locate nodes on the returned list that are in a notReady state and have the same IP address as another node in the list.

3. To manually delete a notReady node:

   kubectl delete node NODE-NAME
   

   Where NODE-NAME is the name of the node in the notReady state.

502 Bad Gateway After OIDC Login

Symptom

You experience a “502 Bad Gateway” error from the NSX load balancer after you log in to OIDC.

Explanation

A large response header has exceeded your NSX-T load balancer maximum response header size. The default maximum response header size is 10,240 characters and should be resized to 50,000.

Workaround

If you experience this issue, manually reconfigure your NSX-T request_header_size and response_header_size to 50,000 characters. For information about configuring NSX-T default header sizes, see OIDC Response Header Overflow in the Knowledge Base.

Difficulty Changing Proxy for Windows Workers

You must configure a global proxy in the Tanzu Kubernetes Grid Integrated Edition tile > Networking pane before you create any Windows workers that use the proxy.

You cannot change the proxy configuration for Windows workers in an existing cluster.

Character Limitations in HTTP Proxy Password

For vSphere with NSX-T, the HTTP Proxy password field does not support the following special characters: & or ;.

Error After Modifying Your Harbor Storage Configuration

Symptom

You receive the following error after modifying your existing Harbor installation’s storage configuration:

Error response from daemon: manifest for ... not found: manifest unknown: manifest unknown

Explanation

Harbor does not support modifying an existing Harbor installation’s storage configuration.

Workaround

To modify your Harbor storage configuration, re-install Harbor. Before starting Harbor, configure the new Harbor installation with the desired configuration.

Ingress Controller Statefulset Fails to Start After Resizing Worker Nodes

Symptom

Permissions are removed from your cluster’s files and processes after resizing the persistent disk during a cluster upgrade. The ingress controller statefulset fails to start.

Explanation

When resizing a persistent disk, Bosh migrates the data from the old disk to the new disk but does not copy the files’ extended attributes.

Workaround

To resolve the problem, complete the steps in Ingress controller statefulset fails to start after resize of worker nodes with permission denied in the VMware Tanzu Knowledge Base.

Azure Default Security Group Is Not Automatically Assigned to Cluster VMs

Symptom

You experience issues when configuring a load balancer for a multi-control plane node Kubernetes cluster or creating a service of type LoadBalancer. Additionally, in the Azure portal, the VM > Networking page does not display any inbound and outbound traffic rules for your cluster VMs.

Explanation

As part of configuring the Tanzu Kubernetes Grid Integrated Edition tile for Azure, you enter Default Security Group in the Kubernetes Cloud Provider pane. When you create a Kubernetes cluster, Tanzu Kubernetes Grid Integrated Edition automatically assigns this security group to each VM in the cluster. However, on Azure the automatic assignment may not occur.

As a result, your inbound and outbound traffic rules defined in the security group are not applied to the cluster VMs.

Workaround

If you experience this issue, manually assign the default security group to each VM NIC in your cluster.

One Plan ID Longer than Other Plan IDs

Symptom

One of your plan IDs is one character longer than your other plan IDs.

Explanation

In TKGI, each plan has a unique plan ID. A plan ID is normally a UUID consisting of 32 alphanumeric characters and 4 hyphens. However, the Plan 4 ID consists of 33 alphanumeric characters and 4 hyphens.

Solution

You can safely configure and use Plan 4. The length of the Plan 4 ID does not affect the functionality of Plan 4 clusters.

If you require all plan IDs to have identical length, do not activate or use Plan 4.

Database Cluster Stops After a Database Instance is Stopped

Symptom

After you stop one instance in a multiple-instance database cluster, the cluster stops, or communication between the remaining databases times out, and the entire cluster becomes unreachable.

The following might be in your UAA log:

WSREP has not yet prepared node for application use

Explanation

The database cluster is unable to recover automatically because a member is no longer available to reconcile quorum.

Velero Back Up Fails for vSphere PVs Attached to Clusters on Kubernetes v1.20 and Later

Symptom

Backing up vSphere persistent volumes using Velero fails and your Velero backup log includes the following error:

rpc error: code = Unknown desc = Failed during IsObjectBlocked check: Could not translate selfLink to CRD name

Explanation

This is a known issue when backing up clusters on Kubernetes v1.20 and later using the Velero Plugin for vSphere v1.1.0 or earlier.

Workaround

To resolve the problem, complete the steps in Velero backups of vSphere persistent volumes fail on Kubernetes clusters version 1.20 or higher (83314) in the VMware Tanzu Knowledge Base.

Creating Two Windows Clusters at the Same Time Fails

Symptom

The first time that you try to create two Windows clusters at the same time, the creation of one of the clusters fails. If you run pks cluster CLUSTER-NAME to examine the last action taken on the cluster, you see the following:

Last Action: Create
Last Action State: failed
Last Action Description: Instance provisioning failed: There was a problem completing your request.
. . .
operation: create, error-message: Failed to acquire lock
. . .
locking task id is 111, description: 'create deployment'

Explanation

This is a known issue that occurs the first time that you create two Windows clusters concurrently.

Workaround

Recreate the failed cluster. This issue only occurs the first time that you create two Windows clusters concurrently.

Deleted Clusters are Listed in Cluster Lists

Symptom

After running tkgi delete-cluster and cluster deletion has completed, the deleted cluster continues to be listed when running tkgi clusters.

Workaround

You must manually remove the deleted cluster using a customized version of the ncp_cleanup script. For more information, see Deleting a Tanzu Kubernetes Grid Integrated Edition cluster with “tkgi delete-cluster” stuck “in progress” status in the VMware Tanzu Knowledge Base.

Creating a New Cluster Fails With the Error 'IP Is Already Allocated’

Symptom

Creating a new cluster fails while using the Antrea CNI. The coreDNS add-on errand logs an error similar to the following:

The Service \"kube-dns\" is invalid: spec.clusterIPs: Invalid value: []string{\"10.100.200.2\"}: failed to allocated ip:10.100.200.2 with error:provided IP is already allocated\n"

Workaround

Delete the failed cluster and run tkgi create-cluster again.

BOSH Director Logs the Error 'Duplicate vm extension name’

Symptom

After you uninstall TKGI, then reinstall TKGI in the same environment, BOSH Director logs errors similar to the following:

.../gems/bosh-director-0.0.0/lib/bosh/director/deployment_plan/cloud_manifest_parser.rb:120:in `parse_vm_extensions': Duplicate vm extension name 'disk_enable_uuid' (Bosh::Director::DeploymentDuplicateVmExtensionName)

Explanation

The pivotal-container-service cloud-config was not removed when you uninstalled the TKGI tile, and it remained active. When you reinstalled the TKGI tile, an additional pivotal-container-service cloud-config was created, causing the metrics_server to fall into a crash-loop state.

Workaround

You must manually remove the pivotal-container-service cloud-config after removing your TKGI deployment, including after removing the TKGI tile from Ops Manager.

For more information, see “Duplicate vm extension name” error when metrics_server runs on Director VM in Tanzu Kubernetes Grid Integrated Edition in the VMware Tanzu Community Knowledge Base.

The TKGI API FQDN Must Not Include Trailing Whitespace

Symptom

Your TKGI logs include the following error:

'uaa'. Errors are:- Error filling in template 'uaa.yml.erb' (line 59: Client redirect-uri is invalid: uaa.clients.pks_cli.redirect-uri Client redirect-uri is invalid: uaa.clients.pks_cluster_client.redirect-uri)

Explanation

The TKGI API fully-qualified domain name (FQDN) for your cluster contains leading or trailing whitespace.

Workaround

Do not include whitespace in the TKGI tile API Hostname (FQDN) field.

Some Kubernetes Logs Are Not Forwarded after Upgrading

This issue is fixed in TKGI v1.12.1.

Symptom

After you upgrade TKGI to v1.12.0, some Kubernetes logs are no longer forwarded by Fluent Bit.

Explanation

In TKGI v1.12.0, Fluent Bit has been upgraded from v1.3.4 to v1.5.7. In Fluent Bit v1.5.7, the default Kubernetes annotation buffer size is 32 KB, limiting the size of Kubernetes log metadata to 32 KB by default. The Kubernetes log metadata in your environment exceeds this limit, and the log entries have been discarded.

Workaround

To reduce the length of the Kubernetes metadata applied to your log entries, reduce the total size of the Kubernetes annotation environment variables you have defined in your environment.

The TKGI CLI is Unable to Run Simultaneous Commands

This issue is fixed in TKGI v1.12.1.

Symptom

Your automated tasks occasionally attempt to run simultaneously, blocking some of the tasks.

Workaround

In TKGI v1.12.1 and later, increase the length of the TKGI CLI timeout. For more information about the TKGI timeout, see tkgi login in the TKGI CLI documentation.

TKGI Does Not Support Updating Dedicated Tier 1 Clusters

TKGI does not support updating dedicated Tier 1 clusters. You can use a Network Profile to create a dedicated Tier 1 cluster, but you cannot use tkgi update-cluster to update the cluster afterward.

TKGI Does Not Support CVDS / NVDS Mixed Environments

TKGI does not support environments where there are multiple matching networks, such as a mixed CVDS/NVDS environment.

Symptom

TKGI logs errors similar to the following in an environment with multiple matching networks:

LastOperationstatus='failed', description='Instance provisioning failed: 
There was a problem completing your request. Please contact your operations team providing the following information: 
service: p.pks, service-instance-guid: ..., broker-request-id: ..., task-id: ..., operation: create, 
error-message: Unknown CPI error 'Unknown' with message 'undefined method `mob' for #<VimSdk::Vim::OpaqueNetwork:' in create_vm' CPI method

Explanation

TKGI cannot identify which of the matching networks you intend to use and has selected the wrong network.

tkgi clusters Returns the Incorrect Number of Worker Instances

This issue is fixed in TKGI v1.12.2.

Symptom

The tkgi clusters --json command returns an incorrect kubernetes_worker_instances worker instance count for clusters configured using a Compute Profile.

The Tier-1 Gateway and Static Routes for the LoadBalancer CRD Are Not Deleted While Deleting Policy API-Based Clusters

Symptom

After successfully deleting a Policy API-based cluster with LoadBalancer CRDs, you notice that the cluster’s Tier-1 gateway, static routes for the LoadBalancer CRD, and some TKGI NSX-T resources were not deleted, and the following error has been logged:

Found errors in the request. Please refer to the related errors for details.

[Routing] Removal of edge cluster from Tier1 logical router is not allowed as multicast is enabled on it.

Workaround

To work around this issue:

• If the cluster has not been deleted:
  1. Delete all of the cluster’s LoadBalancer CRDs before deleting the cluster.

Occasionally update-cluster Does Not Complete for Windows Workers

Symptom

Occasionally, tkgi update-cluster hangs while updating a Windows worker node instance and the BOSH task cannot finish and exits.

Additionally, your ovsdb-server log, located at C:\var\vcap\sys\log\openvswitch-windows\ovsdb-server/job-service-wrapper.err.log, reports an error similar to the following after the flushing processes:

Pid-Guard : ovsdb-server is already runing, please stop it first
At C:\var\vcap\jobs\openvswitch-windows\bin\ovsdb-server_ctl.ps1:30 char:5
+     Pid-Guard $PIDFILE "ovsdb-server"
+     ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : NotSpecified: ( [Write-Error], WriteErrorException
    + FullyQualifiedErrorId : Microsoft.PowerShell.Commands.WriteErrorException,Pid-Guard

Workaround

To resolve this issue for a single Windows worker:

1. SSH to the affected worker node.
   

2. Run the following:

   rm C:\var\vcap\sys\run\openvswitch-windows\ovsdb-server.pid
   

3. Wait for the ovsdb-server process to start.

4. Confirm the dependent services also start.

Using a New Compute Profile to Add and Remove Node Pools Deletes and Recreates the Node Pool VMs

When you update a cluster using a Compute Profile to remove existing node pools and create new node pools, BOSH deletes the VMs for the existing node pools and creates new VMs instead of renaming the existing VMs and updating them.

Rotate-Certificates Returns 'Could Not Fetch VMs Info’ When Rotating Certificates for More than 1000 Clusters

Symptom

When you rotate certificates by running the pks rotate-certificates CLI command with the --only-nsx parameter, in an environment with more than one thousand clusters, the command returns the following error:

Error: Cluster ... not found.
ERROR 15217 — [nio-9021-exec-6] i.pivotal.pks.error.ApiExceptionHandler : Error: Status: 500; 
ErrorMessage: <nil>; Description: There was a problem completing your request. 
    Please contact your operations team providing the following information: 
    ...operation: bind - error-message: gathering binding info Could not fetch VMs info

Workaround

To rotate the certificates that did not automatically rotate, you must rotate the certificates manually. For more information, see How to rotate Tanzu Kubernetes Grid Integrated Edition tls-nsx-t cluster certificate in the VMware Tanzu Knowledge Base.

vRealize Log Insight Integration Does Not Support HTTPS Connections

Symptom

The Tanzu Kubernetes Grid Integrated Edition Management Console integration to vRealize Log Insight does not support connections to the HTTPS port on the vRealize Log Insight server.

Workaround

1. Use SSH to log in to the Tanzu Kubernetes Grid Integrated Edition Management Console appliance VM.
2. Open the file /lib/systemd/system/pks-loginsight.service in a text editor.
3. Add -e LOG_SERVER_ENABLE_SSL_VERIFY=false.

4. Set -e LOG_SERVER_USE_SSL=true.

   The resulting file should look like the following example:

   ExecStart=/bin/docker run --privileged --restart=always --network=pks
   -v /var/log/journal:/var/log/journal
   --name=pks-loginsight
   -e TYPE=gear2-vm
   -e LOG_SERVER_HOST=${LOGINSIGHT_HOST}
   -e LOG_SERVER_PORT=${LOGINSIGHT_PORT}
   -e LOG_SERVER_ENABLE_SSL_VERIFY=false
   -e LOG_SERVER_USE_SSL=true
   -e LOG_SERVER_AGENT_ID=${LOGINSIGHT_ID}
   pksoctopus/vrli-journald:v07092019
   

5. Save the file and run systemctl daemon-reload.

6. To restart the vRealize Log Insight service, run systemctl restart pks-loginsight.service.

Tanzu Kubernetes Grid Integrated Edition Management Console can now send logs to the HTTPS port on the vRealize Log Insight server.

vSphere HA causes Management Console ovfenv Data Corruption

Symptom

If you enable vSphere HA on a cluster, if the TKGI Management Console appliance VM is running on a host in that cluster, and if the host reboots, vSphere HA recreates a new TKGI Management Console appliance VM on another host in the cluster. Due to an issue with vSphere HA, the ovfenv data for the newly created appliance VM is corrupted and the new appliance VM does not boot up with the correct network configuration.

Workaround

• In the vSphere Client, right-click the appliance VM and select Power > Shut Down Guest OS.
• Right-click the appliance again and select Edit Settings.
• Select VM Options and click OK.
• Verify under Recent Tasks that a Reconfigure virtual machine task has run on the appliance VM.
• Power on the appliance VM.

Base64 encoded file arguments are not decoded in Kubernetes profiles

Symptom

Some file arguments in Kubernetes profiles are base64 encoded. When the management console displays the Kubernetes profile, some file arguments are not decoded.

Workaround

Run echo "$content" | base64 --decode

Network profiles not immediately selectable

Symptom

If you create network profiles and then try to apply them in the Create Cluster page, the new profiles are not available for selection.

Workaround

Log out of the management console and log back in again.

Real-Time IP information not displayed for network profiles

Symptom

In the cluster summary page, only default IP pool, pod IP block, node IP block values are displayed, rather than the real-time values from the associated network profile.

Workaround

None

Error After Modifying Your Harbor Storage Configuration

Symptom

You receive the following error after modifying your existing Harbor installation’s storage configuration:

Error response from daemon: manifest for ... not found: manifest unknown: manifest unknown

Explanation
