[Solved] Docker create unknown interface on host machine

I use latest docker version on ubuntu 20.04.01

I noticed it create unknown network interface on my host machine (additional to docker0). i dont have any container that use custom network interface or i haven’t created new docker network interface (only has default bridge, host and none)

That interface disappear if i stop docker service systemctl stop docker but it reappear once it started also i uninstalled sudo apt purge docker-ce docker-ce-cli containerd.io and installed again however doesn’t solve.

how to remove that permanently?

By not starting containers :slight_smile:

Each container will get a veth interface per network it participates in.

thanks for explanation.

HI All,

I was literally new to docker. can some one tell me how to run javaws command inside docker container. I created docker container for my java application and logged into it and ran
"javaws http://ip of container:port which i exposed in docker file/rtccClient/rtcc.jnlp" it says “bash: javaws: command not found”. I create image using ibmcom/websphere-liberty:latest as base image
