Docker for the Absolute Beginner - Hands On - DevOps | Udemy

 

docker run: runs the container

• downloads the image if it is not locally stored
• appending a command behind allows execution of the command after running the container
• running the container with -d tag allows it to run in the background and not on the console

docker ps: lists current running containers

• by adding -a, it also shows stopped or exited containers

docker stop: stops a running container by ID or name

docker rm: remove a container

• not able to be seen with docker ps -a

docker images: lists current downloaded images

 

docker rmi: removes downloaded image by name

 

docker pull: downloads an image without running it

 

The container runs as long as the process inside is running. The completed process exits the container.

 

docker exec: executes the command to a running container

 

docker attach: attaches to a running background container
