Bug 1955969: - Makes port names unique. #181

adduarte · 2021-05-05T22:54:08Z

The bugzilla in question is rooted on attempting to create
ports with the same name.

This patch uses the subnet and netids as name suffixes for ports.

Also limits the length of the port name to no more than 255 characters, which is in line with what the current neutron db schema can tolerate.

Do you plan on changing port names in Terraform as well?

Also this requires a review by the Kuryr folk:

The logic for shortening the the port name in case it's too long takes the last 255 chars, I would have personally kept the first chars since the name is supposed to be for humans. Not that it matters, I expect we never end up in a situation where the port name is that long anyway...

mandre · 2021-05-07T06:46:27Z

@adduarte I hope you don't mind, I changed the commit message. Your commit still had the WIP tag in its subject.

EmilienM · 2021-05-07T07:15:58Z

/hold
until someone explains correctly why we don't comment the code here.
I requested that we comment the 255 number to explain why we made that decision.
Having it in the commit message is not enough. It is good practice to comment directly in the code.

Thank you.

You're entirely correct, I've made the requested change.

Please note that backporting this to 4.7 will break CNO's ability to deploy an API LB through Octavia, effectively breaking installation with Kuryr. It'd require some more effort to make it work.
