admin_port not being properly transposed when launching keystone

[Jeff Lane ]

I noticed this issue while trying to launch devstack. When I got to the point where keystone is supposed to start, it fails to start because of the following traceback:

Traceback (most recent call last):
  File "/opt/stack/keystone/bin/keystone-all", line 112, in <module>
    options = deploy.appconfig('config:%s' % paste_config)

If you look at the full debug output, admin_port is clearly identified as 35357:

(keystone-all): 2013-07-16 11:16:02,807 DEBUG cfg log_opt_values admin_endpoint = http://192.168.0.100:%(admin_port)s/
(keystone-all): 2013-07-16 11:16:02,807 DEBUG cfg log_opt_values admin_port = 35357

but the value of admin_port is not being resolved in the %(admin_port)s variable in the admin endpoint url.

See the full debug output here:
http://pastebin.ubuntu.com/5881166/

Including the command line used to generate that output.

The only way to work around this, I've found, is to enusre that instead of %(variable)s in the endpoint definition, the values are hard coded:

admin_endpoint = http://192.168.0.100:35357/
public_endpoint = http://192.168.0.100:5000/

Doing this in keystone.conf, I am able to successfully start keystone.

Unfortunately, changing the default configuration values won't fix this for existing configurations.

It looks like oslo.config is jumping in to apply the same functionality that we were applying here:

Is there a workaround for this? I'm hitting this every time now for the last 2 days and I'm not able to proceed.

[Apurva TN (athippe)]

I hardcoded the admin_port and public_port values in lib/keystone and it works fine for me.

[Abishek Subramanian (absubram)]

Can you please give me the full path to the file? I don't see a "lib/keystone" in /opst/stack/keystone

[Andrea Giardini (agiardini)]

I modified the file /etc/keystone/keystone.conf hardcoding admin_port and public_port and now it works

[Apurva TN (athippe)]

path would be devstack/lib/keystone

please help me about the how can i change for "redstack install" in rove-integration.

working around with a temp hack-
1. Edited devstack/lib/keystone to put values for update public_endpoint,cadmin_endpoint with relevant ports.
2. Add read and execute permissions for /usr/local/lib/python2.7/dist-packages/ and
    read permissions for /usr/lib/python2.7/dist-packages/

This appears to work OK in master. I'm using the following config values:

    public_port = 5001
    public_endpoint = http://localhost:%(public_port)s/
    admin_port = 35358
    admin_endpoint = http://localhost:%(admin_port)s/

Are you still having this issue and if you are what branch are you running?
