Install docker:[1]
apt-key adv --keyserver hkp://pgp.mit.edu:80 --recv-keys 2C52609D echo 'deb https://apt.dockerproject.org/repo ubuntu-trusty main' >> /etc/sources.list.d/docker.list apt-get update apt-get install docker-engine
Issues
- DNS inside containers may have 4.4.4.4 and 8.8.8.8 hard coded, so they won't see your local LAN.
- Docker creates a network interface on 172.17.0.0/16, which may conflict with VPNs and/or Vagrant, LXC, etc.
In /etc/default/docker.io add your settings:
DOCKER_OPTS="--dns 192.168.your.dns --bip=169.254.0.1/16"
If you're using systemd, these need to go in /etc/systemd/system/docker.service.d/docker.conf instead:
[Service] ExecStart= ExecStart=/usr/bin/docker -d -H fd:// --dns 192.168.your.dns --bip=169.254.0.1/16
You may also need this on there as well:
--fixed-cidr=169.254.0.0/16
Restarting docker won't pick these changes up - you need to blow away the interface and whatnot as well:
systemctl daemon-reload systemctl stop docker ip link set docker0 down brctl delbr docker0 iptables -t nat -F systemctl start docker
Notes
