Question
Why docker0 network interface is shown on the Plesk server?
# ip a | grep docker
3: docker0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc noqueue state DOWN group default
inet 172.17.0.1/16 brd 172.17.255.255 scope global docker0
Answer
The docker0 network interface is added on the server, after installation of the Docker extension.
The docker0 network interface is the bridge device for Docker.
All traffic from the Docker containers flows over it to the Docker daemon, which handles routing on behalf of the container.
