Comment 3 for bug 1820928

This is not specific to ceilometer chart.

We observed keystone auth token issues after or during application apply.
All the openstack commands are broken because of the following error:
Failed to discover available identity versions when contacting http://keystone.openstack.svc.cluster.local/v3. Attempting to parse version from URL.
Unable to establish connection to http://keystone.openstack.svc.cluster.local/v3/auth/tokens: HTTPConnectionPool(host='keystone.openstack.svc.cluster.local', port=80): Max retries exceeded with url: /v3/auth/tokens (Caused by NewConnectionError('<requests.packages.urllib3.connection.HTTPConnection object at 0x7fc90f088cd0>: Failed to establish a new connection: [Errno -2] Name or service not known',))

In this case, keystone auth token issue happened during ceilometer chart installation. It failed to be installed because ceilometer-db-sync job failed. The ceilometer-db-sync job actually creates ceilometer resources through gnocchi REST API which requires to request keystone token.

We have similar error from internal sanity.
