Warning: When you configure the Tanzu Kubernetes Grid Integrated Edition tile, do not use spaces in any field entries. This includes spaces between characters as well as leading and trailing spaces. If you use a space in any field entry, the deployment of Tanzu Kubernetes Grid Integrated Edition fails.

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 AZ where you want to deploy the TKGI API and TKGI Database.

    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 infrastructure subnet that you created for Tanzu Kubernetes Grid Integrated Edition component VMs, such as the TKGI API and TKGI Database VMs.
  5. Under Service Network, select the services subnet that you created for Kubernetes cluster VMs.
  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

      Note: If you deployed a global HTTP load balancer for Ops Manager without a certificate, you can configure the load balancer to use this newly-generated certificate. To configure your Ops Manager load balancer front end certificate, see Configure Front End in Preparing to Deploy Ops Manager on GCP Manually.

  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.
  4. Under Worker VM Max in Flight, enter the maximum number of non-canary worker instances to create or update 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. 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-T, and are a beta feature on vSphere with Flannel.

  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, Tanzu Kubernetes Grid Integrated Edition 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 should 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.

  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.
    Plan pane configuration
  18. (Optional) To allow users to create pods with privileged containers, select the Allow Privileged option. For more information, see Pods in the Kubernetes documentation.

    Note: Enabling the Allow Privileged option means that all containers in the cluster will run in privileged mode. Pod Security Policy provides a privileged parameter that can be used to enable or disable Pods running in privileged mode. As a best practice, if you enable Allow Privileged, define PSP to limit which Pods run in privileged mode. If you are implementing PSP for privileged pods, you must enable Allow Privileged mode.

  19. (Optional) Enable or disable one or more admission controller plugins: PodSecurityPolicy and SecurityContextDeny. For more information see Using Admission Control Plugins for Tanzu Kubernetes Grid Integrated Edition Clusters.

    Note: To use PodSecurityPolicy features, you must use Ops Manager v2.10.17 or later.

  20. (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

  21. (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.

  22. (Optional) To configure when the node drains, enable 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 kills 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.

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.

    This 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 Tanzu Kubernetes Grid Integrated Edition tile is aborted.

  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 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.

Resource Config

To modify the resource configuration of Tanzu Kubernetes Grid Integrated Edition and specify your TKGI API load balancer, 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. For the TKGI Database job:

    • Leave the LOAD BALANCERS field blank.
    • (Optional) If you do not use a NAT instance, select INTERNET CONNECTED. This allows component instances direct access to the internet.

  4. For the TKGI API job:

    • Enter the name of your TKGI API load balancer in the LOAD BALANCERS field, prefixed with tcp:. For example, tcp:TKGI-API-LB. Replace TKGI-API-LB with the name of your TKGI API load balancer. The name of your TKGI API load balancer is the name you configured in the Create a Load Balancer section of Creating a GCP Load Balancer for the TKGI API.

      Note: After you click Apply Changes for the first time, BOSH assigns the TKGI API VM an IP address. BOSH uses the name you provide in the LOAD BALANCERS field to locate your load balancer and then connect the load balancer to the TKGI API VM using its new IP address.

      * (Optional) If you do not use a NAT instance, select INTERNET CONNECTED. This allows component instances direct access to the internet.

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