Flush Expired Openstack Keystone Tokens

without comments

After a while of running Openstack and performing a lot of testing (especially Tempest) you may find that your database seems to get pretty full … and this is partly down to expired keystone token’s that remain in the DB table.

To resolve this simply setup a periodic Cron job to execute

1
# /usr/bin/keystone-manage token_flush

This will remove all expired tokens to help clean-up the DB a bit

Of course, this action better to insert as cron task:

1

3
4
# cat keystone_token_flush
#!/bin/bash

10 * * * * root /usr/bin/keystone-manage token_flush

Any client speaking to OpenStack Swift can also be used to store objects
in a Pithos deployment…

It is lie in some cases ….
