Then, a user could ask udev to execute a script that would docker exec my-container mknod newDevX c 42 <minor> the required device when it is added. As soon as I do docker exec -it bash the CLI hangs completely, I cannot even Ctrl+C. This will start a new bash process in an already running container. For example, we can print the directory structure of the container using the ls command: $ docker exec -ti ubuntu ls bin dev home lib32 libx32 mnt proc run set-envs. 23:2376. docker run -e "TERM=xterm-256color" image_name:latest. The -e is used to set the environmental variables of the Docker container image. ofdmj xkek frfeh wultbc mpg cmzli tsjgn lusarz nknee ceqk
