Warning: Refer to the Release Notes for current version support, known issues, and other important information.
If upgrading to NSX-T v3.1.0, note the current DRS mode setting, then change DRS mode to Manual. For more information, see Pods Stop After Upgrading From NSX-T v3.0.2 to v3.1.0 in the Tanzu Kubernetes Grid Integrated Edition Release Notes.
Confirm that your vSphere v6.5, v6.7, or v7.0 installation is on the supported version and patch for NSX-T v3.0.
- Refer to the VMware Product Interoperability Matrices.
- If necessary, update to the required vSphere version or patch before proceeding with the upgrade of NSX-T.
Upload the NSX-T upgrade bundle using the NSX-T Manager and proceed with the upgrade process by following the instructions in the UI.
For more information, refer to the NSX-T Data Center Upgrade Guide documentation.
If you set DRS mode to Manual above, restore DRS to its original setting.
If you made architectural changes to your NSX-T environment that affect TKGI, such as adding or updating a VIP address, or a load balancer for the NSX-T Management Cluster, update the BOSH Director and TKGI tiles with the new or updated IP addresses:
- In the BOSH Director tile > vCenter Configuration pane, update NSX Address and NSX CA Cert.
- In the TKGI tile > Networking pane, update NSX Manager hostname and NSX Manager CA Cert.
- After making any updates to the BOSH Director or TKGI tiles:
- On the Installation Dashboard in Ops Manager, click Review Pending Changes.
- Expand the Errands list for TKGI.
- Ensure that the Upgrade all clusters errand is selected.
- Click Apply Changes.
Each version of TKGI is compatible with multiple versions of Ops Manager. See VMware Tanzu Network to determine if your Ops Manager version is compatible with TKGI v1.10.
To upgrade Ops Manager:
Log in to Ops Manager.
Click your username in the top right corner and navigate to Settings > Export Installation Settings.
Click Export Installation Settings.
- Ops Manager exports an encrypted archive of your current installation configuration.
- Later, you import this configuration into to your upgraded Ops Manager.
Log in to vCenter Server using the vSphere Client.
Shut down the Ops Manager VM.
Deploy the upgraded Ops Manager VM by following the first two steps of Deploying Ops Manager with NSX-T for TKGI:
Using a browser, navigate to the newly-deployed Ops Manager web interface.
On the welcome page, select Import Existing Installation.
Browse to and select the installation configuration archive you exported.
Log in to Ops Manager
Click Apply Changes.
Verify that the BOSH Director for vSphere tile shows the target, updated version.
When you upgrade TKGI, your configuration settings typically migrate to the new version automatically. To download and import a TKGI version:
Download the target version of the product from VMware Tanzu Network.
Import the target version of the TKGI tile to the Ops Manager Installation Dashboard.
Click Review Pending Changes.
Expand the Errands dropdown and enable or disable Upgrade all clusters errand
- See Deciding Between Full and Two-Phase Upgrade to decide whether to upgrade TKGI-provisioned Kubernetes clusters along with TKGI, or upgrade them later.
- VMware recommends that you upgrade Kubernetes clusters along with TKGI if possible.
- Enable the Upgrade all clusters errand to upgrade clusters along with TKGI.
Warning: Disabling the Upgrade all clusters errand causes the TKGI version tagged in your Kubernetes clusters to fall behind the TKGI tile version. If you disable the Upgrade all clusters errand when upgrading the TKGI tile, you must upgrade all your Kubernetes clusters before the next TKGI upgrade.
Note: If you are upgrading TKGI on NSX-T v2.5, you must select the Upgrade all clusters errand or plan to upgrade all clusters individually before upgrading to NSX-T v3.0.
Set the Run smoke tests errand to On. The errand uses the TKGI CLI to create a Kubernetes cluster and then delete it. If the creation or deletion fails, the errand fails and the installation of the TKGI tile is aborted.
TKGI requires a Xenial stemcell. A stemcell for Windows 2019 is also required if you intend to create Windows worker-based clusters. For information about Windows stemcells, see Configuring Windows Worker-Based Clusters.
Note: VMware recommends that you review the Tanzu Network metadata and confirm stemcell version compatibility before using the Tanzu Network APIs to update the stemcells in your automated pipeline. For more information, see the API reference.
If Ops Manager does not have the Xenial stemcell required for TKGI v1.10, the TKGI tile displays the message Missing stemcell. To download and import a new Xenial stemcell, follow the steps below:
On the TKGI tile, click the Missing stemcell link.
In the Stemcell Library, locate the TKGI tile and note the required stemcell version.
Navigate to the Stemcells (Ubuntu Xenial) page on VMware Tanzu Network and download the required stemcell version for your IaaS.
Return to the Installation Dashboard in Ops Manager and click Stemcell Library.
On the Stemcell Library page, click Import Stemcell and select the stemcell file you downloaded from VMware Tanzu Network.
Select the TKGI tile and click Apply Stemcell to Products.
Verify that Ops Manager successfully applied the stemcell. The stemcell version you imported and applied appears in the Staged column for TKGI.
Return to the Installation Dashboard.
To complete the upgrade of the TKGI tile:
Return to the Installation Dashboard in Ops Manager.
Click Review Pending Changes. For more information about this Ops Manager page, see Reviewing Pending Product Changes.
Click Apply Changes.
(Optional) If you enabled the Upgrade all clusters errand, you can use the BOSH CLI to monitor its progress:
- Log in to the BOSH Director by running
bosh -e MY-ENVIRONMENT log-infrom a VM that can access your TKGI deployment. For more information, see Using BOSH Diagnostic Commands in Tanzu Kubernetes Grid Integrated Edition.
bosh -e MY-ENVIRONMENT tasks.
- Locate the task number for the errand in the # column of the BOSH output.
bosh task TASK-NUMBER, replacing
TASK-NUMBERwith the task number you located in the previous step.
- Log in to the BOSH Director by running
Verify that the TKGI tile is updated to the target version.
After you complete the upgrade to TKGI v1.10, complete the following verifications and upgrades:
- Update the TKGI and Kubernetes CLIs
- Upgrade Kubernetes Clusters if Needed
- Verify TKGI Upgrade
- Upgrade NSX-T Data Center to v3.0 or v3.1
- (Optional) Upgrade to vSphere 7
Update the TKGI and Kubernetes CLIs on any local machine where you run commands that interact with your upgraded version of TKGI.
To update your CLIs, download and re-install the TKGI and Kubernetes CLI distributions that are provided with TKGI on VMware Tanzu Network.
For more information about installing the CLIs, see the following topics:
If you upgraded TKGI with the Upgrade all clusters errand disabled, the next step is to upgrade the Kubernetes clusters individually using the TKGI CLI.
Log in to the TKGI environment using the TKGI CLI.
Run the command
tkgi clustersto list all Kubernetes clusters with their current versions and status:
TKGI Version Name k8s Version Plan Name UUID Status Action 1.9.0 tkgi-cluster-1-small 1.17.5 small 0bea03c8-af47-48e8-b249-814c0bc407b9 succeeded CREATE 1.9.0 tkgi-cluster-2-medium 1.17.5 medium 5d9f4501-70cb-460b-9d78-0afbc074cb8c succeeded CREATE 1.9.0 tkgi-cluster-3-large 1.17.5 large b448117a-bb6f-49de-bc9b-452588bd44ef succeeded CREATE
Update each cluster one-by-one using the command
tkgi upgrade-cluster CLUSTER-NAME.
- You do not have to wait for each upgrade to complete before upgrading the next one.
- The advantage of running each upgrade separately is that it makes troubleshooting easier. BOSH assigns a unique task ID to each cluster upgrade.
When the cluster upgrades are complete, run the command
tkgi clustersand verify that they list the target version:
TKGI Version Name k8s Version Plan Name UUID Status Action 1.10.0 tkgi-cluster-1-small 1.18.8 small 0bea03c8-af47-48e8-b249-814c0bc407b9 succeeded UPGRADE 1.10.0 tkgi-cluster-2-medium 1.18.8 medium 5d9f4501-70cb-460b-9d78-0afbc074cb8c succeeded UPGRADE 1.10.0 tkgi-cluster-3-large 1.18.8 large b448117a-bb6f-49de-bc9b-452588bd44ef succeeded UPGRADE
To verify successful upgrade, create a test cluster:
tkgi create-cluster tkgi-cluster-4-test --external-hostname tkgi-cluster-test --plan medium --num-nodes 3
Note: Use only lowercacse characters when naming your cluster if you manage your clusters with Tanzu Mission Control (TMC). Clusters with names that include an uppercase character cannot be attached to TMC.
tkgi clustersto verify that the new cluster is created with the appropriate version of TKGI and Kubernetes:
$ tkgi clusters TKGI Version Name k8s Version Plan Name UUID Status Action 1.10.0 tkgi-cluster-4-test 1.18.8 medium 5d9f4501-70cb-460b-9d78-0afbc074cb8c succeeded CREATE 1.10.0 tkgi-cluster-1-small 1.18.8 small 0bea03c8-af47-48e8-b249-814c0bc407b9 succeeded UPGRADE 1.10.0 tkgi-cluster-2-medium 1.18.8 medium 5d9f4501-70cb-460b-9d78-0afbc074cb8c succeeded UPGRADE 1.10.0 tkgi-cluster-3-large 1.18.8 large b448117a-bb6f-49de-bc9b-452588bd44ef succeeded UPGRADE
After upgrading TKGI and its Kubernetes clusters to v1.10 and NSX-T to v3.0, you can upgrade vSphere to v7. This upgrade includes upgrading the vCenter Server Appliance and each ESXi host, in that order.
- Upgrade vCenter. Refer to Upgrading the vCenter Server Appliance in the vCenter documentation.
- Upgrade each ESXi host, one at a time.
- Put the ESXi host into maintenance mode.
- Upgrade the ESXi host. Refer to Upgrading ESXi hosts in the vSphere documentation.
- Using the NSX-T Manager web interface for Transport Nodes, install the vSphere 7.0 VIBS onto the ESXi host.
- Using the NSX Manage web interface, verify that the ESXi host is in a “Success” state. If it is not, click the Resolve button.
- Remove the ESXi host from maintenance mode.
- Repeat the process for each ESXi host in your vCenter cluster that is part of your TKGI domain.
