Configuration File to Cluster Class Variable Translations

This topic explains how variables in workload cluster configuration files translate to variable settings within a class-based Cluster objects and their ClusterBootstrap and other subordinate objects in Tanzu Kubernetes Grid (TKG). For an example Cluster object and its subordinate objects, see Example Cluster Object and Its Subordinate Objects below.

Overview: Configuration File and Cluster Class Variables

Configuration file variables and class-based cluster variables differ:

  • Configuration file variables are:

    • Formatted as environment variables, all-caps with underscores.
    • Set in a cluster configuration file that has a flat structure, or set as environment variables.
    • Listed and described in the Configuration File Variable Reference.
    • Example setting: 
      TKG_CUSTOM_IMAGE_REPOSITORY: stg-project.vmware.com

  • Class-based cluster variable settings are nested YAML settings within Cluster or ClusterBootstrap object specs:

    • Cluster object settings are:

      • Most of the cluster settings available, and can be changed arbitrarily.
      • Defined by the ClusterClass object set as the cluster’s spec.topology.class value.
      • Set in the controlPlane, workers or variables blocks under spec.topology.

      • Example setting:

        variables:
- name: imageRepository
  value:
    host: stg-project.vmware.com
    • ClusterBootstrap settings are a few one-time settings for container networking and other low-level infrastructure that cannot be changed in an existing cluster.

When you run the tanzu cluster create command with a cluster configuration file as described in Create a Class-Based Cluster, the Tanzu CLI performs this translation.

Node Configuration

The table below lists variables for configuring the control plane and worker nodes, and the operating system that the node instances run. For information about the variables in the Configuration File Variables column, see Node Configuration in Configuration File Variable Reference.

In the Class-based Cluster Object Structure column, all name / value pair settings are located in the Cluster object definition under spec.topology.variables. The example code in this column applies to Cluster objects on vSphere.

Pod Security Admission (PSA) Controller

The table below lists variables for configuring Pod Security Standards for Pod Security Admission Controller. For information about the variables in the Configuration File Variables column, see Pod Security Standards for Pod Security Admission Controller in Configuration File Variable Reference.

In the Class-based Cluster Object Structure column, all name / value pair settings are located in the Cluster object definition under spec.topology.variables.

Configuration File Variables Class-based Cluster Object Structure 
 POD_SECURITY_STANDARD_DEACTIVATED: false POD_SECURITY_STANDARD_AUDIT: privileged POD_SECURITY_STANDARD_WARN: privileged POD_SECURITY_STANDARD_ENFORCE: baseline 
 - name: podSecurityStandard value: deactivated: false audit: “privileged” enforce: “privileged” warn: “baseline” auditVersion: “v1.26” enforceVersion: “v1.26” warnVersion: “v1.26” exemptions: namespaces: [“kube-system”, “tkg-system”]

Cluster Autoscaler

When ENABLE_AUTOSCALER is true, the Tanzu CLI creates a Deployment object for Cluster Autoscaler and adds Cluster Autoscaler annotations to the Cluster object. For information about the variables in the Configuration File Variables column below, see Cluster Autoscaler in Configuration File Variable Reference.

Configuration File Variables Class-based Cluster and Autoscaler Deployment Object Structure 
 AUTOSCALER_SCALE_DOWN_DELAY_AFTER_ADD: 10m AUTOSCALER_SCALE_DOWN_DELAY_AFTER_DELETE: 10s AUTOSCALER_SCALE_DOWN_DELAY_AFTER_FAILURE: 3m AUTOSCALER_SCALE_DOWN_UNNEEDED_TIME: 10m AUTOSCALER_MAX_NODE_PROVISION_TIME: 15m AUTOSCALER_MAX_NODES_TOTAL: 0
In Cluster Autoscaler Deployment object:
 spec: containers: - args: … - –scale-down-delay-after-add=10m - –scale-down-delay-after-delete=10s - –scale-down-delay-after-failure=3m - –scale-down-unneeded-time=10m - –max-node-provision-time=15m - –max-nodes-total=0
 
 AUTOSCALER_MAX_SIZE_0: 12 AUTOSCALER_MIN_SIZE_0: 8 AUTOSCALER_MAX_SIZE_1: 10 AUTOSCALER_MIN_SIZE_1: 6 AUTOSCALER_MAX_SIZE_2: 8 AUTOSCALER_MIN_SIZE_2: 4
If AUTOSCALER_MAX_SIZE_ or AUTOSCALER_MIN_SIZE_ are not set, the annotations settings take the values of WORKER_MACHINE_COUNT_*.		 In the Cluster object, under spec.topology.workers:
 machineDeployments: - class: tkg-worker metadata: annotations: cluster.x-k8s.io/cluster-api-autoscaler-node-group-max-size: “12” cluster.x-k8s.io/cluster-api-autoscaler-node-group-min-size: “8” … name: md-0 - class: tkg-worker metadata: annotations: cluster.x-k8s.io/cluster-api-autoscaler-node-group-max-size: “10” cluster.x-k8s.io/cluster-api-autoscaler-node-group-min-size: “6” … name: md-1 …

Proxy and Private Image Registry

This section lists variables for using proxies and private image registries, for example in an internet-restricted deployment.

In the Class-based Cluster Object Structure column, all name / value pair settings are located in the Cluster object definition under spec.topology.variables.

Configuration File Variables Class-based Cluster Object Structure Notes 
 TKG_CUSTOM_IMAGE_REPOSITORY: example.com/yourproject TKG_CUSTOM_IMAGE_REPOSITORY_SKIP_TLS_VERIFY: true
 
 - name: imageRepository value: host: example.com/yourproject tlsCertificateValidation: enabled: false
 tldCertificateValidation.enabled reverses the boolean setting for TKG_CUSTOM_IMAGE_REPOSITORY_SKIP_TLS_VERIFY and is not written if its value is true. 
 TKG_HTTP_PROXY_ENABLED: true TKG_HTTP_PROXY: http://proxy.example.com:80 TKG_HTTPS_PROXY: https://proxy.example.com:3128 TKG_NO_PROXY: .noproxy.example.com,noproxy.example.com,192.168.0.0/24
 
 - name: proxy value: httpProxy: http://proxy.example.com:80 httpsProxy: https://proxy.example.com:3128 noProxy: - .noproxy.example.com - noproxy.example.com - 192.168.0.0/24 - […]
 Internally, the Tanzu CLI appends to the noProxy list values that are not set in a configuration file, as described in Proxy Configuration. 
 TKG_PROXY_CA_CERT: “LS0tLSBL[…]” TKG_CUSTOM_IMAGE_REPOSITORY_CA_CERTIFICATE: MIIEpgIH[…]"
 
 - name: trust value: - name: proxy data: LS0tLSBL[…] - name: imageRepository data: MIIEpgIH[…]
 Values are base64-encoded CA certificates.
TKG_PROXY_CA_CERT takes precedence over TKG_CUSTOM_IMAGE_REPOSITORY_CA_CERTIFICATE, and trust imageRespository value is not written if trust proxy value is set.		 
 ADDITIONAL_IMAGE_REGISTRY_1: “example.com/otherregistry-1” ADDITIONAL_IMAGE_REGISTRY_1_SKIP_TLS_VERIFY: false ADDITIONAL_IMAGE_REGISTRY_1_CA_CERTIFICATE: “LS0tLSBL[…]” ADDITIONAL_IMAGE_REGISTRY_2: “example.com/otherregistry-2” ADDITIONAL_IMAGE_REGISTRY_2_SKIP_TLS_VERIFY: true ADDITIONAL_IMAGE_REGISTRY_3: “example.com/otherregistry-3” ADDITIONAL_IMAGE_REGISTRY_3_SKIP_TLS_VERIFY: false ADDITIONAL_IMAGE_REGISTRY_3_CA_CERTIFICATE: “MIIEpgIH[…]”

Common Variables

The following table lists variables that are common to all target platforms.

For information about the variables in the Configuration File Variables column, see Common Variables for All Target Platforms in Configuration File Variable Reference.

In the Class-based Cluster Object Structure column, all name / value pair settings are located in the Cluster object definition under spec.topology.variables.

Antrea CNI

This section lists variables for configuring a cluster’s Antrea container network interface (CNI). The class-based cluster variables reside in the AntreaConfig object that is referenced under the ClusterBootstrap object’s spec.cni.refName property.

Class-based clusters support many Antrea configuration options that do not have corresponding TKG configuration file variables. For all Antrea configuration options that are settable for class-based Cluster objects, see Feature Gates and other topics in the Antrea documentation.

In the AntreaConfig Object Structure column, all settings are located in the AntreaConfig object definition, under spec.antrea.config.
