Kubernetes service account automatic configuration

This topic tells you about the resources that you create for Kubernetes service account automatic configuration for AMR authentication and authorization.

Overview

This topic describes which resources play a role in the default configuration and how to troubleshoot. For more information about the resources, for example, if you use means to manage your service accounts or have other requirements related to roles and bindings, see User-defined kubernetes service account configuration

The package-level configuration has a component top level key (TLK) prefix and this topic describes how Tanzu Application Platform configurations can influence this prefix.

Observer

Observer configuration in the Tanzu Application Platform context has the prefix TLK amr.observer. For authentication and authorization, the Tanzu Application Platform profiles influence automatic configuration. Observer can only automatically configure itself when co-located with the CloudEvent Handler, which is in the full or view profile. If this is not the case auth.kubernetes_service_accounts.autoconfigure is set to false at installation.

If auth.kubernetes_service_accounts.enable and auth.kubernetes_service_accounts.autoconfigure are true, the observer package creates the following resources to set up authentication automatically in the amr-observer-system namespace:

  • a ServiceAccount named amr-observer-editor that observer uses to send requests to the CloudEvent Handler
  • a Secret named amr-observer-edit-token of type kubernetes.io/service-account-token which generates a long-lived token for the service account
  • a ClusterRole named tanzu:amr:observer:edit defining the necessary update permissions for all resources in cloudevents.amr.apps.tanzu.vmware.com
  • a ClusterRoleBinding named tanzu:amr:observer:editor binding the defined role to the service account

If auth.kubernetes_service_accounts.autoconfigure is set to false, you must configure the observer package with all the above resources manually. For information about how to set up the observer, see User-defined Kubernetes service account configuration.

CloudEvent Handler

You can find the CloudEvent Handler configuration in the Tanzu Application Platform context under the TLK amr.cloudevent_handler. This prefix is not stripped in this case.

On the package level, if amr.cloudevent_handler.auth.kubernetes_service_accounts.enable and amr.cloudevent_handler.auth.kubernetes_service_accounts.autoconfigure are true, the package creates the following resources to set up authentication automatically in the metadata-store namespace:

  • a ServiceAccount named amr-cloudevent-handler-editor that clients use to send requests to the CloudEvent Handler
  • a Secret named amr-cloudevent-handler-edit-token of type kubernetes.io/service-account-token which generates a long-lived token for the service account
  • a ClusterRole named tanzu:amr:cloudevent-handler:edit defining the necessary update permissions for all resources in cloudevents.amr.apps.tanzu.vmware.com
  • a ClusterRoleBinding named tanzu:amr:cloudevent-handler:editor binding the defined role to the service account

GraphQL handler

You can find the GraphQL configuration in the Tanzu Application Platform context under the TLK amr.graphql. This prefix is not stripped in this case.

If amr.graphql.auth.kubernetes_service_accounts.enable and amr.graphql.auth.kubernetes_service_accounts.autoconfigure are true, the package creates the following resources to set up authentication automatically in the metadata-store namespace:

  • a ServiceAccount named amr-graphql-viewer that clients use to send requests to the graphql interface
  • a Secret named amr-graphql-view-token of type kubernetes.io/service-account-token which generates a long-lived token for the service account
  • a ClusterRole named tanzu:amr:graphql:view defining the necessary get permissions for all resources in graphql.amr.apps.tanzu.vmware.com
  • a ClusterRoleBinding named tanzu:amr:graphql:viewer binding the defined role to the service account
