Docker

Configuration

• delete network link sudo ip link del docker0
• sudo ip link add name docker0 type bridge && sudo ip addr add dev docker0 172.17.0.1/16
• modify daemon.json:
• DNS https://development.robinwinslow.uk/2016/06/23/fix-docker-networking-dns/
  • nslookup <some-site> to get DNS SERVER
  • Add "dns": ["<DNS SERVER>"] to /etc/docker/daemon.json
  • sudo service docker restart

Usage

• docker inspect $(docker ps -aq) | less - inspect all
• start a container
  • docker run --rm -it alpine:latest sh
  • docker run --rm alpine:latest tail -f /dev/null
• host.docker.internal - resolves to the internal IP address used by the host
• access host:

  • extra_hosts:
    - host.docker.internal:10.36.1.55
    

• Fix route after VPN sudo route add -net 172.17.0.0 netmask 255.255.0.0 dev docker0
• fix vim echo "export TERM=xterm" >> ~/.bashrc
• Disconnect Ctrl-p + Ctrl-q
• Build && Run d build -t foo . && docker run -it foo
• Wait command tail -f /dev/null
• Clean
  • docker rmi $(docker images --format '{{.ID}}' --filter=dangling=true)
  • docker volume rm $(docker volume ls -f dangling=true -q)
  • docker images -a | grep "pattern" | awk '{print $3}' | xargs docker rmi
