Options missing from metadata_agent.ini

[Matt Kassawara]

The metadata agent requires at least the following authentication options, but they are missing from the auto-generated metadata_agent.ini file:

[DEFAULT]
auth_uri = http://controller:5000
auth_url = http://controller:35357
auth_region = RegionOne
auth_type = password
project_domain_id = default
user_domain_id = default
project_name = service
username = neutron
password = password

Hi Matt,

Just to confirm that these config items were not in the static 'metadata_agent.ini' file either? If so then how did users config the settings in releases prior to Mitaka?

Thanks,
Martin

In Liberty and prior releases, the metadata_agent.ini file contained similar options [1] that became defunct by changes to the keystone middleware library. The file should contain the current variant of these options. After deprecation, I manually implemented the current variant of these options in the installation guide. However, the current metadata_agent.ini file generated by DevStack lacks these options, which tells me that the agent apparently reads them from elsewhere... perhaps the neutron.conf file. Not exactly sure when this changed, but I need to investigate further to determine the validity of this bug.

The metadata agent apparently no longer requires these options. Digging around led me to a couple of patches [1][2]. The first patch significantly impacts documentation and contains the DocImpact flag. At the time, the DocImpact flag generated bugs in the openstack-manuals repository. For some reason, the bug generated by this patch [3] was changed to "fix released" without any documentation patches. So, I'm changing the bug in openstack-manuals to "triaged" and need to address it.
