Ok I found this one. the function pkgos_read_admin_creds() in postinst
script is never run. instead the one in config is used.
(Probably we should delete the
pkgos_read_admin_creds() definition in postinst, since it is never used
there.)
Anyway. I understood the function itself.
And I found the bug !
The function looks for the config parameter
auth_host, which is not defined in metadata_agent.ini (it is in
neutron.conf)
It then overwrites the auth_url parameter.
But actually it should look first at auth_url, extract auth_host from
there and then write auth_url again.
If I define auth_host in metadata_agent.ini file, you're script seems to
work (this is a workaround for the problem).
But according to openstack code auth_host is not a defined configuration
option in metadata_agent.ini file.
I can imagine the following solutions:
- rewrite pkgos_read_admin_creds() to use auth_url values (and this
without braking other invocations of this function !)
- define pkgos_read_admin_creds_metadata_only() function as a
replacement in metadata-agent.
- introduce debconf neutron-metadata/auth_url and remove
neutron-metadata/auth_host and change the scripts accordingly.
I'm currently not capable of implementing any of these three solutions.
Any other ideas ?
Cheers
