An annotation is a pair of key-value. The key has two parts, viz. a name and an optional prefix in DNS format. The limitations on name is 63, prefix 253 chars. The limitation on total size of all key+value pairs combined is 256KB. https://kubernetes.io/docs/concepts/overview/working-with-objects/annotations/#syntax-and-character-set Fixes: https://github.com/containers/podman/issues/21663 Signed-off-by: Vikas Goel <vikas.goel@gmail.com>
