I've set up a Docker container for my node app and ran it using
docker run -p 4500:4500 my_node_app It launched pm2 in no-daemon mode. CTRL+C and exit don't work. I've tried docker stop my_node_app in another terminal window but to no avail. Appreciate any help.
You will be able to see currently running docker containers using below command.
docker ps
Then copy the CONTAINER ID of the running container and execute the following command
docker stop <container_id>
Please replace with a real value.
dockerd in the console.
docker kill was the correct answer until I read superuser.com/questions/756999/…, so it is worth pointing out that stop will actually kill the container. It just kills it by trying to be polite (at first). :-)
You can try this, pretty easy script
docker container kill $(docker ps | awk '/lookup_value/ {print $1}') Explained
List containers in tabular structure
docker ps Result
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 763e1a00808e 7bb2586065cd "docker-entrypoint.s…" 2 months ago Up 2 weeks 3306/tcp, 33060/tcp mysql_1 763e1a00999b 7bb2586065cd "docker-entrypoint.s…" 1 months ago Up 2 weeks 3307/tcp, 33061/tcp mysql_2 Isolate your container
awk /mysql_1/ Result
763e1a00808e 7bb2586065cd "docker-entrypoint.s…" 2 months ago Up 2 weeks 3306/tcp, 33060/tcp mysql_1 Isolate first tab value which is the container ID
awk ' /mysql_1/ {print $1}' Result
763e1a00808e So in conclusion this will isolate and send the kill or stop command the container id matching the image name
docker container kill $(docker ps | awk '/image_name/ {print $1}')
grep, it's actuall a quite useful answer. hard to upvote it, though, because of the bad grep usage.
Do docker container ls to find the container name if you don't know it already, then docker kill container_name.

docker ps -a -q?alternative aws
docker kill $(docker ps -q) docker ps -q get id all containers
The command docker kill $(docker ps -q) uses to stop running containers.
Breaking it down:
docker ps -q: This part of the command is used to list the IDs of the currently running Docker containers. The -q option stands for "quiet" and is used to only display the container IDs without any additional information.
$(docker ps -q): This command substitution syntax ($(...)) takes the output of docker ps -q (which is a list of container IDs) and substitutes it into the overall command.
docker kill: sending a signal to stop a running container. It is equivalent to running docker stop, but with a default signal of SIGKILL, which forcefully terminates the container.
Putting it all together, docker kill $(docker ps -q) stops all running Docker containers by obtaining their IDs from the output of docker ps -q and then using docker kill to send the stop signal to each identified container.
This command is useful when you want to quickly stop all running containers on your Docker host. Keep in mind that this forcefully terminates the containers, and any unsaved data or state in those containers may be lost. Use it with caution, especially in a production environment.
