#DOCKER RUN IMAGE WITH IMAGE ID HOW TO#

But what happens when you already have a container?

The docker run command creates a new container from the specified image.

I had to stop the container from another terminal in the above case. In other words, you cannot enter anything, cannot run command inside the container like you did earlier: :~$ docker run -t ubuntu bash ThatвЂ™s a tricky situation because in that case, youвЂ™ll have a pseudo terminal (if you use the -t option) but you wonвЂ™t have the STDIN. :~$ docker run -i ubuntu bashД«6b79a9f7789 ubuntu 'bash' 27 seconds ago Exited (0) 9 seconds ago loving_galileo What happens if you only use the -t (terminal/tty) option? In that case, youвЂ™ll see an interactive prompt but if you exit the interactive prompt (using Ctrl+D or exit command), you exit the container and the container stops. :/# echo this is a new containerДЁ2766613e7bc ubuntu 'bash' 2 minutes ago Up 2 minutes determined_blackburnД¦098c44f2407 ubuntu 'bash' 27 seconds ago Exited (0) 8 seconds ago bold_benzДЁ2766613e7bc ubuntu 'bash' 2 minutes ago Up 2 minutes determined_blackburn What happens if you only use the -i (interactive) option? The problem here is that if you exit the container, the container stops. If you do not use the -d option, docker run will create a new container and youвЂ™ll have a terminal in interactive mode running bash shell.ДЄs you can see in the example below, the container is created and I am automatically inside the container (bash shell). What happens if you donвЂ™t run it as a daemon (-d option) in the background? In the above example, I didnвЂ™t name the container so it was randomly named determined_blackburn.ДЄnd as you can see, the container is running bash command in the background. :~$ docker run -it -d ubuntu bashДЁ2766613e7bc0ae98887bb1c776fa0de7f3c4771db9ac7ffc5db5c2c68ab497bД¬ONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMESДЁ2766613e7bc ubuntu 'bash' 4 seconds ago Up 3 seconds determined_blackburn The reason for running bash as command here is that the container wonвЂ™t stop immediately.

The -d option (daemon mode) keeps the container running in the background.

The -t option gives you a terminal (so that you can use it as if you used ssh to enter the container).

The -i option means that it will be interactive mode (you can enter commands to it).

The above command will create a new container with the specified name from the specified docker image. If you want to run a docker container with a certain image and a specified command, you can do it in this fashion: docker run -it -d -name container_name image_name bash IвЂ™ll explain in detail what the above two commands do and what is the -it option in the docker run and exec command. :~$ docker exec -it my_container bashД«in boot dev etc home lib lib64 media mnt opt proc root run sbin srv sys tmp usr var

HereвЂ™s an example where I create a new container with Ubuntu as the base image and then I enter the running Ubuntu container and run the ls command: :~$ docker run -it -d -name my_container ubuntu bashД§e77640bca686108ad415318278a1fa148e1c84d3b180276e19ec2b970ba9b67 You can create and run a container with the following command: docker run -it -d -name container_name image_name bashДЄnd then, if you want to enter the container (to run commands inside the container interactively), you can use the docker exec command: docker exec -it container_ID_or_name /bin/bash
