Issue

  • How to increase the OpenStack Keystone Ticket Timeout?
  • Some operations are getting a Timeout from Keystone before it completes. Is it possible to increase the ticket validation?

Resolution

  • If you are experiencing some kind of timeout or the Keystone Ticket is expiring during an operation, for instance when you upload a glance image and it takes more time than the ticket, you can increase the keystone ticket changing the keystone.conf file:
    Inside the /etc/keystone/keystone.conf you have the following option:
# Amount of time a token should remain valid (in seconds).
# (integer value)
expiration=3600

You can safely change it to a new value in order to fit in your needs, for instance 7200 or another value:

# Amount of time a token should remain valid (in seconds).
# (integer value)
expiration=7200

Afterwards keystone needs to be restarted.

Note: If you have more than one controller and runs it behind an HAProxy, you can safely change the parameter expiration in the keystone.conf in each controller and then restart each one separately. HAProxy will take care to redirect the services to a active service.

The keystone expiration setting can be configured via Director using the following parameter file:

parameter_defaults:
    ControllerExtraConfig:
        keystone::token_expiration: 28800
