-    A label's key and value must begin with a letter or number, and may contain letters, numbers, hyphens, dots, and underscores, up to 63 characters each. Optionally, the key can begin with a valid DNS subdomain prefix and a single slash (`/`). In this case, the maximum allowed length of the domain prefix is 253 characters. For instance, `example.com/my-app` is a valid key for a label.

In this case, the maximum *total* length of the key is 128 characters, with up to 62 characters after the forward slash. The prefix must adhere to RFC 1123 DNS subdomain restrictions.
