Comment 0 for bug 1657130

cloud-init sometimes times out and fails to fetch metadata in the OpenStack environment when the Controller node is under high workload.

The default timeout value is 5 seconds and it may be too small in some cases where the Controller node is too busy to respond to the metadata request from the instance in time.

There is a 'timeout' configuration setting, as in...

  datasource:
    OpenStack:
      timeout: 30

...but this value is not used by the get_data method in cloudinit/sources/DataSourceOpenStack.py, because get_data is called from cloudinit/sources/__init__.py with no keyword arguments:

                LOG.debug("Seeing if we can get any data from %s", cls)
                s = cls(sys_cfg, distro, paths)
                if s.get_data():
                    myrep.message = "found %s data from %s" % (mode, name)
                    return (s, type_utils.obj_name(cls))
