Docker Network Configuration

Network Configuration for Docker containers

Docker automatically creates a DOCKER0 bridge and automatically assigns an IP segment when it starts. How do you change the IP of Docker?

Ip addr Show can view Docker0 's network information

IP addr del 172.17.0.1/16 dev docker0 delete original IP

IP addr Add 172.25.25.1/24 dev Docker0 adding a new IP

This adds a temporary IP message that restarts the device and reverts to the initial IP how to permanently change the Docker network

Systemctl Stop Docker first closes Docker
