Known Issues

• DOCKER-USER iptables chain is missing docker/for-linux#810. Users cannot perform additional container network traffic filtering on top of this iptables chain. You are not affected by this issue if you are not customizing iptables chains on top of DOCKER-USER.

  Workaround is to insert the iptables chain after docker daemon starts.

  iptables -N DOCKER-USER
  iptables -I FORWARD -j DOCKER-USER
  iptables -A DOCKER-USER -j RETURN
