The change here enabled usage of timeout and retry for. [Test Case] 1. Launch an instance on openstack. 2. Verify inconsistent use of 'timeout' in /var/log/cloud-init.log $ grep http://169.254.169.254/openstack /var/log/cloud-init.log | grep 0/ | head -n 2 2017-03-03 16:51:23,824 - url_helper.py[DEBUG]: [0/1] open 'http://169.254.169.254/openstack' with {'url': 'http://169.254.169.254/openstack', 'allow_redirects': True, 'headers': {'User-Agent': 'Cloud-Init/0.7.9'}, 'method': 'GET', 'timeout': 10.0} configuration 2017-03-03 16:51:24,384 - url_helper.py[DEBUG]: [0/6] open 'http://169.254.169.254/openstack' with {'url': 'http://169.254.169.254/openstack', 'allow_redirects': True, 'headers': {'User-Agent': 'Cloud-Init/0.7.9'}, 'method': 'GET', 'timeout': 5.0} configuration 3. enable proposed, update, upgrade 4. clean rm -Rf /var/lib/cloud /var/log/cloud-init* 5. reboot 6. re-check step 2, expect see 'timeout' is consistent. [Regression Potential] low chance for regression. Slower boot times but more reliable on a non-perform ant metadata service. === End SRU Template === 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)) To manage notifications about this bug go to: https://bugs.launchpad.net/cloud-init/+bug/1657130/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~group.of.nepali.translators Post to : group.of.nepali.translators@lists.launchpad.net Unsubscribe : https://launchpad.net/~group.of.nepali.translators More help : https://help.launchpad.net/ListHelp
