  • This is a bug report
  • This is a feature request
  • I searched existing issues before opening this one

Expected behavior

DOCKER-USER iptables chain should exist in docker-ce 19.03.3 just like it did in previous releases.

Actual behavior

Install docker-ce 19.03.3 and there is no DOCKER-USER iptables chain.

Steps to reproduce the behavior

Install docker-ce 19.03.3 on Ubuntu 16.04 or CentOS 7.
iptables -nvL
There is no DOCKER-USER listed in the output.
