# providers is a list of credential provider helper plugins that will be enabled by the kubelet.
# Multiple providers may match against a single image, in which case credentials
# from all providers will be returned to the kubelet. If multiple providers are called
# for a single image, the results are combined. If providers return overlapping
# auth keys, the value from the provider earlier in this list is used.
providers:
  # name is the required name of the credential provider. It must match the name of the
  # provider executable as seen by the kubelet. The executable must be in the kubelet's
  # bin directory (set by the --image-credential-provider-bin-dir flag).
  - name: ecr-credential-provider
    # matchImages is a required list of strings used to match against images in order to
    # determine if this provider should be invoked. If one of the strings matches the
    # requested image from the kubelet, the plugin will be invoked and given a chance
    # to provide credentials. Images are expected to contain the registry domain
    # and URL path.
    #
    # Each entry in matchImages is a pattern which can optionally contain a port and a path.
    # Globs can be used in the domain, but not in the port or the path. Globs are supported
    # as subdomains like '*.k8s.io' or 'k8s.*.io', and top-level-domains such as 'k8s.*'.
    # Matching partial subdomains like 'app*.k8s.io' is also supported. Each glob can only match
    # a single subdomain segment, so `*.io` does **not** match `*.k8s.io`.
    #
    # A match exists between an image and a matchImage when all of the below are true:
    # - Both contain the same number of domain parts and each part matches.
    # - The URL path of an matchImages must be a prefix of the target image URL path.
    # - If the matchImages contains a port, then the port must match in the image as well.
    #
    # Example values of matchImages:
    # - 123456789.dkr.ecr.us-east-1.amazonaws.com
    # - *.azurecr.io
    # - gcr.io
    # - *.*.registry.io
    # - registry.io:8080/path

    # tokenAttributes is the configuration for the service account token that will be passed to the plugin.
    # The credential provider opts in to using service account tokens for image pull by setting this field.

      # 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. This is useful for plugins
      # that are used to pull images for pods without service accounts (e.g., static pods).

      # to the plugin as part of the CredentialProviderRequest. If any of the keys defined in this list
