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 matchImages: ".dkr.ecr..amazonaws.com" ".dkr.ecr..amazonaws.com.cn" ".dkr.ecr-fips..amazonaws.com" ".dkr.ecr.us-iso-east-1.c2s.ic.gov" ".dkr.ecr.us-isob-east-1.sc2s.sgov.gov" # defaultCacheDuration is the default duration the plugin will cache credentials in-memory # if a cache duration is not provided in the plugin response. This field is required. defaultCacheDuration: "12h" # Required input version of the exec CredentialProviderRequest. The returned CredentialProviderResponse # MUST use the same encoding version as the input. Current supported values are: # - credentialprovider.kubelet.k8s.io/v1 apiVersion: credentialprovider.kubelet.k8s.io/v1 # Arguments to pass to the command when executing it. # +optional # args: # - --example-argument # Env defines additional environment variables to expose to the process. … Attribution: Adapted from Kubernetes Documentation under CC-BY-4.0.
