This article covers list of commands that you should know to manage docker containers in your local machine or server. some of the important commands are docker list containers, start a container and stop container from docker.
Docker container is an isolated packages of software that you can use to run your application, code or any infrastructure. basically, it helps to manage your application code without conflicting with your current machine/server setup.
There are few commands that you need to know to manage docker container. let's start with basic commands.
To start/stop a docker container, you can do that using the command,
docker container start [OPTIONS] <Container id>
Note: you can specify the name or you can just specify the first two digits of the container id.
To stop the container, you need to specify the
stop in the docker container command.
docker container stop [OPTIONS] <Container id>
To stop all the running container, you can use the command,
docker stop $(docker ps -a -q)
Once you stop all containers, you can remove it using the command,
docker container prune
To list all the docker container, you can do that using the command,
docker container ls [OPTIONS]
you can add options such as
--all or -ait shows all the containers in the docker
--size or -s, displays the container along with size
--latest or -lshows latest container first
--last or -nit shows the lastly created containers
To kill a docker container, you can use the command
docker container kill [OPTIONS] <Container ID>
there is a difference between
docker stop and
docker kill container commands.
docker stop will send a signal
SIGTERM and then after some grace period it sends the signal
SIGKILL to stop the containers whereas in
docker kill command, it sends the
SIGKILL command directly.
you need to be careful with
docker kill command, my personal suggestion would be to use
docker stop command. to explain it a simple way, difference is like shutting down your computer vs forcefully removing the plug from socket to turn off the machine.
So far, we have seen the important command that you need to know for docker containers. try to use the above commands and play with it to get hands-on experience. if you feel like any important commands are missing, let me know in the comments below. Happy Coding 🙂
