Limit allowed chars in username or do not use username in code

De situatie

I used [email protected] as username and got an error when generating the Prototype.

Wat er gebeurde er en wat had je verwacht?

Error on Prototype generatie (uses username in domainname, i guess)
Deployment.apps "[email protected]" is invalid: [metadata.name: Invalid value: "[email protected]": a lowercase RFC 1123 subdomain must consist of lower case alphanumeric characters, '-' or '.', and must start and end with an alphanumeric character (e.g. 'example.com', regex used for validation is 'a-z0-9?(.a-z0-9?)*'), metadata.labels: Invalid value: "[email protected]": a valid label must be an empty string or consist of alphanumeric characters, '-', '_' or '.'...

If you solve by choosing not to use the username you might generate a random string instead, but I would advise to solve by limiting allowed chars to domain name RFC + Check code for possible more uses of the username (other limitations).

Hi @FranSlot , This is a similar bug as the one last week. There should be a mapping from the name to the subdomain. For instance, apply a function that removes all characters that are not allowed, or (even better?) substitute them with an allowed character.
