How to detach from Docker Compose
Overview
Docker Compose is a tool that we use when we need to run multiple containers. First, we create a .YML file and write all its configurations. Next, with a single command, we can start all the services.
Command
We can run Docker Compose using the following command.
docker compose run <container name>
We can detach from Docker Compose with below two methods:
- Run docker in the detach mode.
- Detach from an already running docker container.
Run docker in detach mode
We can run Docker Compose in detach mode and provide an option of --dtach or -d to docker compose run command.
Command
The following command shows how we can provide this option to run docker-compose in detach mode.
docker compose run -d <container name>
Detach from an already running Docker container
Following are the two modes of detaching from an already running container.
- Default mode
- Iterative mode
Default mood
If we run a container without an -it or -d option, the "CTRL-c" command will kill the container instead of detaching it. To override this behavior, we need to pass –sig-proxy=false, and then we can use "CTRL-c" as detach command.
Command
The following command shows how to override the "CTRL-c" behavior.
docker run --name test_redis --sig-proxy=false <container name>
Iterative mode
If our container is running in an iterative mode, "CTRL-c" acts as the command for the iterative session, and we use "CTRL-p" or "CTRL-q" to detach.
Command
The following command shows how to override the "CTRL-c" behavior in an iterative session.
docker compose run -it <container name>
