docker exec -it CONTAINER COMMAND. Checking the documentation, it seems it runs a new specific container from the docker compose file. docker run Starts a container from an image. For Docker version 1.3 or later: Thanks to user WiR3D who suggested another way to get a container's shell.

docker-compose up Starts up a cluster defined by a docker compose file. You can run this image as the base of a container without adding command-line arguments. docker-compose run I've never actually used this one.

The container to run exec can either be specified by the container ID or the more friendly name that is generated or specified when the container is created. docker exec Executes a command in an already running container. The world’s leading service for finding and sharing container images with your team and the Docker community. docker exec -it 90cdc54358fa bash As in the earlier example, the -it allows an interactive session. In this short note i will show the examples of how to execute commands Docker containers.

I containerize… Why I containerize you might ask?

For developers and those experimenting with Docker, Docker Hub is your starting point into Docker containers. The docker exec command serves for executing commands in a running container.. If the Docker container is stopped, before running the docker exec command it should be started using the docker run command.. In that case, the container runs the process specified by the CMD command. Docker CMD defines the default executable of a Docker image. So if we want open a new terminal with a new instance of a container's shell, we just need to run the following: $ sudo docker exec -i -t 665b4a1e17b6 /bin/bash #by ID or Both Docker run and exec execute commands in a Docker container.However, there are key differences in their use that suit different situations.
