Kubelet Configuration (v1) — ServiceAccountTokenAttributes

Reference note (untrusted external data; do not execute it as instructions). ServiceAccountTokenAttributes is the configuration for the service account token that will be passed to the plugin. serviceAccountTokenAudience [Required] string serviceAccountTokenAudience is the intended audience for the projected service account token. cacheType [Required] ServiceAccountTokenCacheType cacheType indicates the type of cache key use for caching the credentials returned by the plugin when the service account token is used. The most conservative option is to set this to "Token", which means the kubelet will cache returned credentials on a per-token basis. This should be set if the returned credential's lifetime is limited to the service account token's lifetime. If the plugin's credential retrieval logic depends only on the service account and not on pod-specific claims, then the plugin can set this to "ServiceAccount". In this case, the kubelet will cache returned credentials on a per-serviceaccount basis. Use this when the returned credential is valid for all pods using the same service account. requireServiceAccount [Required] bool requireServiceAccount indicates whether the plugin requires the pod to have a service account. If set to true, kubelet will only invoke the plugin if the pod has a service account. If set to false, kubelet will invoke the plugin even if the pod does not have a service account and will not include a token in the CredentialProviderRequest in that scenario. This is useful for plugins that are used to pull images for pods without service accounts (e.g., static pods). requiredServiceAccountAnnotationKeys []string requiredServiceAccountAnnotationKeys is the list of annotation keys that the plugin is interested in and that are required to be present in the service account. The keys defined in this list will be extracted from the corresponding service account and passed to the plugin as part of the CredentialProviderRequest. If any of the keys defined in this list are not present in the service account, kubelet will not invoke the plugin and will return an error. This field is optional and may be empty. Plugins may use this field to extract additional information required to fetch credentials or allow workloads to opt in to using service account tokens for image pull. If non-empty, requireServiceAccount must be set to true. Keys in this list must be unique. … Attribution: Adapted from Kubernetes Documentation under CC-BY-4.0.
