Resource Naming Convention Validator (DNS-1123)

Kubernetes resource names must be valid DNS-1123 labels: lowercase letters, digits and dashes, starting and ending with an alphanumeric character. The Resource Naming Convention Validator checks a name against these rules and reports any problems.

Paste a candidate name and get an immediate valid/invalid verdict with reasons.
