VM Problems
But a VM is very cheap:)

Let’s use container

Docker

OpenStack on Docker Problems• Well known
• Not support OpenvSwitch• Not support Cinder Volume
• Devstack failed to• Reserve keystone port • install nova-docker• Restart docker
• Nova-docker didn’t support Neutron ML2 Linuxbridge driver
• Neutron failed to ip6tables
14Copyright©2014 NTT corp. All Rights Reserved.
• OpenvSwitch• Select ML2 Linuxbridge as Neutron plugin
• Cinder Volume• Don’t use volume
• Reserve Keystone port ⇒ Bugfix #125740• Install nova-docker ⇒ Bugfix #128746• Restart docker
• Replace command (Workaround)• start-stop-daemon --stop --pidfile "/var/run/docker.pid”
• ML2 Linuxbridge driver ⇒ Bugfix #130520• Don’t use ip6tables
• Disable ipv6 in container(Workaround)• echo 1 > /proc/sys/net/ipv6/conf/default/disable_ipv6
OpenStack on Docker Run

• Jenkins runs shell script
Jenkins Run
#!/usr/bin/env bashset -emkdir -p $BUILD_NUMBER/logsdocker run -v $WORKSPACE/$BUILD_NUMBER/logs:/opt/stack/logs --privileged $DOCKER_IMAGE $GERRIT_REFSPEC
• Docker can bind mount a volume from the host
• Storing log became very easy
