Hey Seongsoo,

I don't think it's supported because most of the time, I believe users end up having a single keystone even in a multiple region environment.

Are you looking for this in order or Keystone to use the closer Keystone?

Thanks
Mohammed

Subject: [magnum] Is magnum support region_name in keystone auth config?
 
You don't often get email from ppiyakk2@printf.kr. Learn why this is important
Hi magnum team.

It seems that a magnum does not support region_name which is in the keystone_auth and keystone_authtoken section in magnum conf.

The internal keystone client of keystoneauth1 only uses the lowest UUID of endpoints for keystone url. [1]

And also KeystoneClientV3 's get_auth[2] and get_legacy_auth[3] also don't support region_name as an argument.

So, My question is how can I make magnum only use the keystone URL written in the config?

Best regards
