Each entry in matchImages is an image 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.\n\nA match exists between an image name and a matchImage entry when all of the below are true\n\nBoth contain the same number of domain parts and each part matches. The URL path of match image 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.\n\nSome example values of matchImages patterns are\n\n123456789.dkr.ecr.us-east-1.amazonaws.com .azurecr.io gcr.io ..registry.io foo.registry.io:8080/path\n\nAttribution: Adapted from Kubernetes Documentation under CC-BY-4.0.
