Engineering Team, which is subscribed to cloud-init. https://bugs.launchpad.net/bugs/1802598 Title: EphemeralIPv4Network: when device has requested existing network config, but link is down, network setup does not bring link up Status in cloud-init: Expired Bug description: EphemeralIPv4Network exists in success too early on network devices with link down. When run against a network interfaces which already has the requested ip configuration and routes but hapeens to be "link down", EphemeralIPv4Network.bringup_device exits immediately after determining that the device has the expected ip address. EphemeralIPv4Network should instead ensure that all configured aspects of a network interface are properly setup before returning the context. Steps to reproduce: echo > ephemeral_test.py <<EOF #!/usr/bin/python3 from cloudinit import log from cloudinit.net.dhcp import EphemeralDHCPv4 from cloudinit.cmd.devel import addLogHandlerCLI LOG = log.getLogger('ephemeraldhcp') addLogHandlerCLI(LOG, log.DEBUG) with EphemeralDHCPv4() as lease: print('LEASE: %s' % lease) EOF chmod 755 ephemeral_test.py lxc launch ubuntu-daily:bionic b1 lxc file push ephemeral_test.py b1/ # lxc has already completed configured the device, so we expect to only see the following ip commands # 'ip', '-family', 'inet', 'addr', 'add' ... # 'ip', 'route', 'show', '0.0.0.0/0' lxc exec b1 /ephemeral_test.py | grep Running # bringing down the link, I'd want to see EphemeralIPv4Network performing a call to [ip link set eth0 up ] lxc exec b1 ip link eth0 down lxc exec b1 /ephemeral_test.py | grep Running To manage notifications about this bug go to: https://bugs.launchpad.net/cloud-init/+bug/1802598/+subscriptions -- Mailing list: https://launchpad.net/~yahoo-eng-team Post to : yahoo-eng-team@lists.launchpad.net Unsubscribe : https://launchpad.net/~yahoo-eng-team More help : https://help.launchpad.net/ListHelp
