Make docker use IPv4 for port binding

Question

I have docker host and inside I have one container.

The docker host is binding the port on IPv6 interface only, not on IPv4.

This is the output

Answer 1

For CentOS users,

I've got same issue on CentOS7 and setting net.ipv4.ip_forward to 1 solves the issue. Please, refer to Docker Networking Disabled: WARNING: IPv4 forwarding is disabled. Networking will not work for more details.
