The above stated command would invoke the bash of the container associated with the specified image name in an interactive shell because of the −i flag. You can launch the bash of a container using the following command − sudo docker run −it bash The Compute Engine and Docker images created by the image builder are stored in the same project as the image builder. Sharing Compute Engine and Docker images. Note that to execute the command inside the container using exec command, your container must be in the running state otherwise it would throw you an error specifying that the container with that container Id is not running.Īnother way to run a command inside a docker container environment is to launch the bash of that particular container and execute commands inside it.

You can copy the container ID of the container in which you want to run the command. The above command will display all the containers with their names, ids and other information.
