What patterns are valid in kubernetes for the names of containers and ports?
I had underscores in the names of ports and containers and got an error. Replacing the underscores with hyphens worked.
Container names and port names must conform to the RFC 1123 definition of a DNS label.
Names must be no longer than 63 characters, must start and end with a lowercase letter or number, and may contain lowercase letters, numbers, and hyphens.
Expressed as a regular expression:
[a-z0-9]([-a-z0-9]*[a-z0-9])?Here's the applicable code in GitHub for checking container names, checking port names, and defining acceptable names.
