Red Hat Bugzilla – Bug 1258562
avahi-cname-manager validity check too restrictive
Last modified: 2017-05-31 14:22:11 EDT
Description of problem:
When using mDNS for development, if the namespace or app name contains a number, adding the CNAME alias will fail. This is a valid domain name and is allowed by OpenShift, which constrains both to alphanumeric characters.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Set up use of mDNS
2. Create app and/or namespace with a digit.
3. Deploy as normal
400 Invlaid CNAME
Note that the typo is in the original message.
Regex check is at https://github.com/openshift/origin-server/blob/master/extras/avahi-cname-manager/bin/avahi-cname-manager#L85 among other places.
We apologize, however, we do not plan to address this report at this time. The majority of our active development is for the v3 version of OpenShift. If you would like for Red Hat to reconsider this decision, please reach out to your support representative. We are very sorry for any inconvenience this may cause.
