  2. Assign AZs and Networks
  3. TKGI API
  4. Plans
  5. Kubernetes Cloud Provider
  6. Networking
  7. UAA
  8. (Optional) Host Monitoring
  9. (Optional) In-Cluster Monitoring
  10. Tanzu Mission Control
  11. VMware CEIP
  12. Storage
  13. Errands
  14. Resource Config


Assign AZs and Networks

To configure the availability zones (AZs) and networks used by the Tanzu Kubernetes Grid Integrated Edition control plane:

  1. Click Assign AZs and Networks.

  2. Under Place singleton jobs in, select the availability zone (AZ) where you want to deploy the TKGI API and TKGI Database VMs.

    Assign AZs and Networks pane in Ops Manager

  3. Under Balance other jobs in, select the AZ for balancing other Tanzu Kubernetes Grid Integrated Edition control plane jobs.

    Note: You must specify the Balance other jobs in AZ, but the selection has no effect in the current version of Tanzu Kubernetes Grid Integrated Edition.

  4. Under Network, select the TKGI Management Network linked to the ls-tkgi-mgmt NSX logical switch you created in the Create Networks Page step of Configuring BOSH Director with NSX for Tanzu Kubernetes Grid Integrated Edition. This provides network placement for Tanzu Kubernetes Grid Integrated Edition component VMs, such as the TKGI API and TKGI Database VMs.
  5. Under Service Network, your selection depends on whether you are installing a new Tanzu Kubernetes Grid Integrated Edition deployment or upgrading from a previous version of Tanzu Kubernetes Grid Integrated Edition.
    • If you are deploying Tanzu Kubernetes Grid Integrated Edition with NSX for the first time, select the TKGI Management Network that you specified in the Network field. You do not need to create or define a service network because Tanzu Kubernetes Grid Integrated Edition creates the service network for you during the installation process.
    • If you are upgrading from a previous version of Tanzu Kubernetes Grid Integrated Edition, then select the Service Network linked to the ls-tkgi-service NSX logical switch that Tanzu Kubernetes Grid Integrated Edition created for you during installation. The service network provides network placement for existing on-demand Kubernetes cluster service instances that were created by the Tanzu Kubernetes Grid Integrated Edition broker.
  6. Click Save.


TKGI API

Perform the following steps:

  1. Click TKGI API.

  2. Under Certificate to secure the TKGI API, provide a certificate and private key pair.
    TKGI API pane configuration
    The certificate that you supply must cover the specific subdomain that routes to the TKGI API VM with TLS termination on the ingress. If you use UAA as your OIDC provider, this certificate must be a proper certificate chain and have a SAN field.

    Warning: TLS certificates generated for wildcard DNS records only work for a single domain level. For example, a certificate generated for *.tkgi.EXAMPLE.com does not permit communication to *.api.tkgi.EXAMPLE.com. If the certificate does not contain the correct FQDN for the TKGI API, calls to the API will fail.

    You can enter your own certificate and private key pair, or have Ops Manager generate one for you.
    To generate a certificate using Ops Manager:

    1. Click Generate RSA Certificate for a new install or Change to update a previously-generated certificate.
    2. Enter the domain for your API hostname. This must match the domain you configure under TKGI API > API Hostname (FQDN) below, in the same pane. It can be a standard FQDN or a wildcard domain.
    3. Click Generate.
      TKGI API certificate generation
  3. Under API Hostname (FQDN), enter the FQDN that you registered to point to the TKGI API load balancer, such as api.tkgi.example.com. To retrieve the public IP address or FQDN of the TKGI API load balancer, log in to your IaaS console.

    Note: The FQDN for the TKGI API must not contain uppercase letters or trailing whitespace.

  4. Under Worker VM Max in Flight, enter the maximum number of non-canary worker instances to create, update or upgrade in parallel within an availability zone.

    This field sets the max_in_flight variable value. The max_in_flight setting limits the number of component instances the TKGI CLI creates or starts simultaneously when running tkgi create-cluster or tkgi update-cluster. By default, max_in_flight is set to 4, limiting the TKGI CLI to creating or starting a maximum of four component instances in parallel.
  5. Enable the Automatic retry on cluster update operations failure option to make tkgi update-cluster retry the cluster update process up to three times if it fails.
  6. Disable the Configure clusters to use private registries option to disable the --private-registries option of the tkgi create-cluster and tkgi update-cluster commands described in Configuring Cluster Access to Private Registries. By default, the ability to configure clusters to use private registries is enabled.
  7. Click Save.


Plans

A plan defines a set of resource types used for deploying a cluster.

Activate a Plan

You must first activate and configure Plan 1, and afterwards you can optionally activate Plan 2 through Plan 10.

To activate and configure a plan, perform the following steps:

  1. Click the plan that you want to activate.

    Note: Plans 11, 12, and 13 support Windows worker-based Kubernetes clusters on vSphere with NSX, and are a beta feature on vSphere with Antrea.

  2. Select Active to activate the plan and make it available to developers deploying clusters.
    Plan pane configuration
  3. Under Name, provide a unique name for the plan.
  4. Under Description, edit the description as needed. The plan description appears in the Services Marketplace, which developers can access by using the TKGI CLI.
  5. Under Master/ETCD Node Instances, select the default number of Kubernetes control plane/etcd nodes to provision for each cluster. You can enter 1, 3, or 5.

    Note: If you deploy a cluster with multiple control plane/etcd node VMs, confirm that you have sufficient hardware to handle the increased load on disk write and network traffic. For more information, see Hardware recommendations in the etcd documentation.

    In addition to meeting the hardware requirements for a multi-control plane node cluster, we recommend configuring monitoring for etcd to monitor disk latency, network latency, and other indicators for the health of the cluster. For more information, see Configuring Telegraf in TKGI.

    WARNING: To change the number of control plane/etcd nodes for a plan, you must ensure that no existing clusters use the plan. Tanzu Kubernetes Grid Integrated Edition does not support changing the number of control plane/etcd nodes for plans with existing clusters.

  6. Under Master/ETCD VM Type, select the type of VM to use for Kubernetes control plane/etcd nodes. For more information, including control plane node VM customization options, see the Control Plane Node VM Size section of VM Sizing for Tanzu Kubernetes Grid Integrated Edition Clusters.

  7. Under Master Persistent Disk Type, select the size of the persistent disk for the Kubernetes control plane node VM.

  8. Under Master/ETCD Availability Zones, select one or more AZs for the Kubernetes clusters deployed by Tanzu Kubernetes Grid Integrated Edition. If you select more than one AZ, Tanzu Kubernetes Grid Integrated Edition deploys the control plane VM in the first AZ and the worker VMs across the remaining AZs. If you are using multiple control plane nodes, deploys the control plane and worker VMs across the AZs in round-robin fashion.

    Note: Tanzu Kubernetes Grid Integrated Edition does not support changing the AZs of existing control plane nodes.

  9. Under Maximum number of workers on a cluster, set the maximum number of Kubernetes worker node VMs that Tanzu Kubernetes Grid Integrated Edition can deploy for each cluster. Enter any whole number in this field.
    Plan pane configuration, part two
  10. Under Worker Node Instances, specify the default number of Kubernetes worker nodes the TKGI CLI provisions for each cluster. The Worker Node Instances setting must be less than, or equal to, the Maximum number of workers on a cluster setting.
    For high availability, create clusters with a minimum of three worker nodes, or two per AZ if you intend to use PersistentVolumes (PVs). For example, if you deploy across three AZs, you must have six worker nodes. For more information about PVs, see PersistentVolumes in Maintaining Workload Uptime. Provisioning a minimum of three worker nodes, or two nodes per AZ is also recommended for stateless workloads.

    For more information about creating clusters, see Creating Clusters.

    Note: Changing a plan’s Worker Node Instances setting does not alter the number of worker nodes on existing clusters. For information about scaling an existing cluster, see Scale Horizontally by Changing the Number of Worker Nodes Using the TKGI CLI in Scaling Existing Clusters.

  11. Under Worker VM Type, select the type of VM to use for Kubernetes worker node VMs. For more information, including worker node VM customization options, see Worker Node VM Number and Size in VM Sizing for Tanzu Kubernetes Grid Integrated Edition Clusters.

    Note: Tanzu Kubernetes Grid Integrated Edition requires a Worker VM Type with an ephemeral disk size of 32 GB or more.

  12. Under Worker Persistent Disk Type, select the size of the persistent disk for the Kubernetes worker node VMs.

  13. Under Worker Availability Zones, select one or more AZs for the Kubernetes worker nodes. Tanzu Kubernetes Grid Integrated Edition deploys worker nodes equally across the AZs you select.

  14. Under Kubelet customization - system-reserved, enter resource values that Kubelet can use to reserve resources for system daemons. For example, memory=250Mi, cpu=150m. For more information about system-reserved values, see the Kubernetes documentation.
    Plan pane configuration, part two

  15. Under Kubelet customization - eviction-hard, enter threshold limits that Kubelet can use to evict pods when they exceed the limit. Enter limits in the format EVICTION-SIGNAL=QUANTITY. For example, memory.available=100Mi, nodefs.available=10%, nodefs.inodesFree=5%. For more information about eviction thresholds, see the Kubernetes documentation.

    WARNING: Use the Kubelet customization fields with caution. If you enter values that are invalid or that exceed the limits the system supports, Kubelet might fail to start. If Kubelet fails to start, you cannot create clusters.

  16. Under Errand VM Type, select the size of the VM that contains the errand. The smallest instance possible is sufficient, as the only errand running on this VM is the one that applies the Default Cluster App YAML configuration.
  17. (Optional) Under (Optional) Add-ons - Use with caution, enter additional YAML configuration to add custom workloads to each cluster in this plan. You can specify multiple files using --- as a separator. For more information, see Adding Custom Linux Workloads.
  18. (Optional) Under Node Drain Timeout(mins), enter the timeout in minutes for the node to drain pods. If you set this value to 0, the node drain does not terminate.
    Node Drain Timeout fields
  19. (Optional) Under Pod Shutdown Grace Period (seconds), enter a timeout in seconds for the node to wait before it forces the pod to terminate. If you set this value to -1, the default timeout is set to the one specified by the pod.

  20. (Optional) To configure when the node drains, activate the following:

    • Force node to drain even if it has running pods not managed by a ReplicationController, ReplicaSet, Job, DaemonSet or StatefulSet.
    • Force node to drain even if it has running DaemonSet-managed pods.
    • Force node to drain even if it has running running pods using emptyDir.
    • Force node to drain even if pods are still running after timeout.

    Warning: If you select Force node to drain even if pods are still running after timeout, the node halts all running workloads on pods. Before enabling this configuration, set Node Drain Timeout to a value greater than 0.

    For more information about configuring default node drain behavior, see Worker Node Hangs Indefinitely in Troubleshooting.

  21. Click Save.

  5. For NSX Manager CA Cert, copy and paste the contents of the NSX Manager CA certificate you created in Generate and Register the NSX Management SSL Certificate and Private Key. Use this certificate and key to connect to the NSX Manager.
  6. The Disable SSL certificate verification check box is not selected by default. In order to deactivate TLS verification, select the check box. If you did not enter a CA certificate, or if your CA certificate is self-signed, you can deactivate TLS verification.

    Note: The NSX Manager CA Cert field and the Disable SSL certificate verification option are intended to be mutually exclusive. If you deactivate SSL certificate verification, leave the CA certificate field blank. If you enter a certificate in the NSX Manager CA Cert field, do not deactivate SSL certificate verification. If you populate the certificate field and deactivate certificate validation, insecure mode takes precedence.

  7. If you are using a NAT deployment topology, leave the NAT mode check box selected. If you are using a No-NAT topology, clear this check box. For more information, see NSX Deployment Topologies for Tanzu Kubernetes Grid Integrated Edition.
  8. If you are using the NSX Policy API, select Policy API mode.
  9. Configure the NSX networking objects, including the Pods IP Block ID, Nodes IP Bock ID, T0 Router ID, Floating IP Pool ID, Nodes DNS, vSphere Cluster Names, and Kubernetes Service Network CIDR Range. Each of the these fields are described in more detail beneath the example screenshots. If you are using the NSX Policy API, you must have created the Pods IP Block ID, Nodes IP Bock ID, T0 Router ID, and Floating IP Pool ID objects using the NSX Policy API. See Create NSX Objects for Kubernetes Clusters Using the Policy Interface.
    NSX Networking configuration pane in Ops Manager
    View a larger version of this image.

    • Pods IP Block ID: Enter the UUID of the IP block to be used for Kubernetes pods. Tanzu Kubernetes Grid Integrated Edition allocates IP addresses for the pods when they are created in Kubernetes. Each time a namespace is created in Kubernetes, a subnet from this IP block is allocated. The current subnet size that is created is /24, which means a maximum of 256 pods can be created per namespace.
    • Nodes IP Block ID: Enter the UUID of the IP block to be used for Kubernetes nodes. Tanzu Kubernetes Grid Integrated Edition allocates IP addresses for the nodes when they are created in Kubernetes. The node networks are created on a separate IP address space from the pod networks. The current subnet size that is created is /24, which means a maximum of 256 nodes can be created per cluster.
      For more information, including sizes and the IP blocks to avoid using, see Plan IP Blocks in Preparing NSX Before Deploying Tanzu Kubernetes Grid Integrated Edition.
    • T0 Router ID: Enter the t0-tkgi T0 router UUID. Locate this value in the NSX UI router overview.
    • Floating IP Pool ID: Enter the ip-pool-vips ID that you created for load balancer VIPs. For more information, see Plan Network CIDRs in Network Planning for Installing Tanzu Kubernetes Grid Integrated Edition with NSX. Tanzu Kubernetes Grid Integrated Edition uses the floating IP pool to allocate IP addresses to the load balancers created for each of the clusters. The load balancer routes the API requests to the control plane nodes and the data plane.
    • Nodes DNS: Enter one or more Domain Name Servers used by the Kubernetes nodes.
    • vSphere Cluster Names: Enter a comma-separated list of the vSphere clusters where you will deploy Kubernetes clusters. The NSX pre-check errand uses this field to verify that the hosts from the specified clusters are available in NSX. You can specify clusters in this format: cluster1,cluster2,cluster3.

      • If the clusters are under multiple different vSphere datacenters, specify them in this format: dc1:cluster1,dc2:cluster2,dc-folder/dc3:cluster3.
    • Kubernetes Service Network CIDR Range: Specify an IP address and subnet size depending on the number of Kubernetes services that you plan to deploy within a single Kubernetes cluster, for example: 10.100.200.0/24. The IP address used here is internal to the cluster and can be anything, such as 10.100.200.0. A /24 subnet provides 256 IPs. If you have a cluster that requires more than 256 IPs, define a larger subnet, such as /20.

    • Under TKGI Operation Timeout, enter the timeout for TKGI-API operation in milliseconds. Increase the timeout if you experience timeouts during cluster deletion in large-scale NSX environments. The default TKGI Operation Timeout value is 120000, 120 seconds. To determine the optimal Operation Timeout setting, see Cluster Deletion Fails in General Troubleshooting.

      Note: If you use the TKGI MC, the TKGI MC configuration YAML nsx_feign_client_read_timeout configuration overrides the TKGI tile TKGI Operation Timeout setting. For more information about configuring the Operation Timeout setting in TKGI MC, see Generate Configuration File and Deploy Tanzu Kubernetes Grid Integrated Edition in Deploy Tanzu Kubernetes Grid Integrated Edition by Using the Configuration Wizard.

  10. (Optional) Configure a global proxy for all outgoing HTTP and HTTPS traffic from your Kubernetes clusters and the TKGI API server. See Using Proxies with Tanzu Kubernetes Grid Integrated Edition on NSX for instructions on how to enable a proxy.

  4. Under TKGI Cluster Access Token Lifetime, enter a time in seconds for the cluster access token lifetime. This field defaults to 600.
  5. Under TKGI Cluster Refresh Token Lifetime, enter a time in seconds for the cluster refresh token lifetime. This field defaults to 21600.

    Note: VMware recommends using the default UAA token timeout values. By default, access tokens expire after ten minutes and refresh tokens expire after six hours.

  6. Under Configure created clusters to use UAA as the OIDC provider, select Enabled or Disabled. This is a global default setting for TKGI-provisioned clusters. For more information, see OIDC Provider for Kubernetes Clusters.


    To configure Tanzu Kubernetes Grid Integrated Edition to use UAA as the OIDC provider:
    1. Under Configure created clusters to use UAA as the OIDC provider, select Enabled.
      OIDC configuration check box
    2. For UAA OIDC Groups Claim, enter the name of your groups claim. This is used to set a user’s group in the JSON Web Token (JWT) claim. The default value is roles.
    3. For UAA OIDC Groups Prefix, enter a prefix for your groups claim. This prevents conflicts with existing names. For example, if you enter the prefix oidc:, UAA creates a group name like oidc:developers. The default value is oidc:.
    4. For UAA OIDC Username Claim, enter the name of your user name claim. This is used to set a user’s user name in the JWT claim. The default value is user_name. Depending on your provider, you can enter claims besides user_name, like email or name.
    5. For UAA OIDC Username Prefix, enter a prefix for your user name claim. This prevents conflicts with existing names. For example, if you enter the prefix oidc:, UAA creates a user name like oidc:admin. The default value is oidc:.

      Warning: VMware recommends adding OIDC prefixes to prevent users and groups from gaining unintended cluster privileges. If you change the above values for a pre-existing Tanzu Kubernetes Grid Integrated Edition installation, you must change any existing role bindings that bind to a user name or group. If you do not change your role bindings, developers cannot access Kubernetes clusters. For instructions, see Managing Cluster Access and Permissions.

  7. (Optional) For TKGI cluster client redirect URIs, enter one or more comma-delimited UAA redirect URIs. Configure TKGI cluster client redirect URIs to assign persistent UAA cluster_client redirect_uri URIs to your clusters. UAA redirect URIs configured in the TKGI cluster client redirect URIs field persist through cluster updates and TKGI upgrades.

        • By default, can create and attach clusters only in the default cluster group.
        • Can create and attach clusters to other cluster groups after an organization.admin user grants them the clustergroup.admin or clustergroup.edit role for those groups.
      • Org Owner users in VMware cloud services have organization.admin permissions in Tanzu Mission Control. These users:

        • Can create cluster groups.
        • Can grant clustergroup roles to service.admin users through the Tanzu Mission Control Access Policy view.

        For more information about role and access policy, see Access Control in the VMware Tanzu Mission Control Product documentation.

    • Tanzu Mission Control Cluster Name Prefix: Enter a name prefix for identifying the Tanzu Kubernetes Grid Integrated Edition clusters in Tanzu Mission Control.
  4. Click Save.

Warning: After the Tanzu Kubernetes Grid Integrated Edition tile is deployed with a configured cluster group, the cluster group cannot be updated.

Note: When you upgrade your Kubernetes clusters and have Tanzu Mission Control integration enabled, existing clusters will be attached to Tanzu Mission Control.


VMware CEIP

Tanzu Kubernetes Grid Integrated Edition-provisioned clusters send usage data to the TKGI control plane for storage. The VMware Customer Experience Improvement Program (CEIP) provides the option to also send the cluster usage data to VMware to improve customer experience.

To configure Tanzu Kubernetes Grid Integrated Edition CEIP Program settings:

  1. Click CEIP.
  2. Review the information about the CEIP.

  3. If you wish to participate in CEIP, select Yes. Otherwise, select No.
  4. If you selected the Yes, complete the following:
    • (Optional) Enter your entitlement account number or Tanzu customer number. If you are a VMware customer, you can find your entitlement account number in your Account Summary on my.vmware.com. If you are a Pivotal customer, you can find your Pivotal Customer Number in your Pivotal Order Confirmation email.
    • (Optional) Enter a descriptive name for your TKGI installation. The label you assign to this installation will be used in CEIP reports to identify the environment.
  5. To provide information about the purpose for this installation, select an option.

  6. Click Save.


Storage

In Storage Configurations, you can configure vSphere CNS settings.

Storage Configurations pane

To configure vSphere CNS:

  1. Select Storage.

  2. (Optional) To enable automatic installation of the vSphere CSI driver on all clusters, select Yes.

    Warning: If you have existing clusters with a manually deployed vSphere CSI driver, you must remove the manually deployed driver after enabling this feature. For more information, see Deploying Cloud Native Storage (CNS) on vSphere.


Errands

Errands are scripts that run at designated points during an installation.

To configure which post-deploy and pre-delete errands run for Tanzu Kubernetes Grid Integrated Edition:

  1. Make a selection in the dropdown next to each errand.

    Note: We recommend that you use the default settings for all errands except for the Run smoke tests errand.

  2. (Optional) Set the Run smoke tests errand to On.

    The Smoke Test errand smoke tests the TKGI upgrade by creating and deleting a test Kubernetes cluster. If test cluster creation or deletion fails, the errand fails, and the installation of the TKGI tile halts.

    The errand uses the TKGI CLI to create the test cluster configured using the configuration settings on the TKGI tile.

  3. (Optional) To ensure that all of your cluster VMs are patched, configure the Upgrade all clusters errand errand to On.

    Updating the Tanzu Kubernetes Grid Integrated Edition tile with a new Linux stemcell and the Upgrade all clusters errand enabled triggers the rolling of every Linux VM in each Kubernetes cluster. Similarly, updating the Tanzu Kubernetes Grid Integrated Edition tile with a new Windows stemcell triggers the rolling of every Windows VM in your Kubernetes clusters.

    Note: VMware recommends that you review the Broadcom Support metadata and confirm stemcell version compatibility before using the Broadcom Support APIs to update the stemcells in your automated pipeline. For more information, see the API reference.


Resource Config

To modify the resource configuration of Tanzu Kubernetes Grid Integrated Edition, follow the steps below:

  1. Select Resource Config.

  2. For each job, review the Automatic values in the following fields:

    • INSTANCES: Tanzu Kubernetes Grid Integrated Edition defaults to the minimum configuration. If you want a highly available configuration (beta), scale the number of VM instances as follows:
      1. To configure your Tanzu Kubernetes Grid Integrated Edition database for high availability (beta), increase the INSTANCES value for TKGI Database to 3.
      2. To configure your Tanzu Kubernetes Grid Integrated Edition API and UAA for high availability (beta), increase the INSTANCES value for TKGI API to 2 or more.

        Warning: High availability mode is a beta feature. Do not scale your TKGI API or TKGI Database to more than one instance in production environments.

    • VM TYPE: By default, the TKGI Database and TKGI API jobs are set to the same Automatic VM type. If you want to adjust this value, we recommend that you select the same VM type for both jobs.

      Note: The Automatic VM TYPE values match the recommended resource configuration for the TKGI API and TKGI Database jobs.

    • PERSISTENT DISK TYPE: By default, the TKGI Database and TKGI API jobs are set to the same persistent disk type. If you want to adjust this value, you can change the persistent disk type for each of the jobs independently. Using the same persistent disk type for both jobs is not required.
  3. Under each job, leave NSX CONFIGURATION and NSX-V CONFIGURATION blank.

    Warning: To avoid workload downtime, use the resource configuration recommended in About Tanzu Kubernetes Grid Integrated Edition Upgrades and Maintaining Workload Uptime.



Step 3: Apply Changes

After configuring the Tanzu Kubernetes Grid Integrated Edition tile, follow the steps below to deploy the tile:

  1. Return to the Ops Manager Installation Dashboard.
  2. Click Review Pending Changes. Select the product that you intend to deploy and review the changes. For more information, see Reviewing Pending Product Changes.
  3. Click Apply Changes.



Step 4: Install the TKGI and Kubernetes CLIs

The TKGI CLI and the Kubernetes CLI help you interact with your Tanzu Kubernetes Grid Integrated Edition-provisioned Kubernetes clusters and Kubernetes workloads. To install the CLIs, follow the instructions below:



Step 5: Verify NAT Rules

If you are using NAT mode, verify that you have created the required NAT rules for the Tanzu Kubernetes Grid Integrated Edition Management Plane. See Create Management Plane in Installing and Configuring NSX-T Data Center v3.0 for TKGI for details.

In addition, for NAT and No-NAT modes, verify that you created the required NAT rule for Kubernetes control plane nodes to access NSX-T Manager. For details, see Create IP Blocks and Pool for Compute Plane in Installing and Configuring NSX-T Data Center v3.0 for TKGI.

If you want your developers to be able to access the TKGI CLI from their external workstations, create a DNAT rule that maps a routable IP address to the TKGI API VM. This must be done after Tanzu Kubernetes Grid Integrated Edition is successfully deployed and it has an IP address. See Create Management Plane in Installing and Configuring NSX-T Data Center v3.0 for TKGI for details.



Step 6: Configure Authentication for Tanzu Kubernetes Grid Integrated Edition

Follow the procedures in Setting Up Tanzu Kubernetes Grid Integrated Edition Admin Users on vSphere in Installing Tanzu Kubernetes Grid Integrated Edition > vSphere.
