Trying to list some Docker commands:
1. docker run
Run a container from an image
2. docker run nginx
Will run an instance of the nginx application on the docker host.
3. docker ps
Lists all running containers
4. docker ps -a
Will list all containers (running, stopped and exited ones)
5. docker stop <id or name>
Stops a container
6. docker rm <id or name>
Remove stopped or exited containers
7. docker images
List of images on the host
8. docker rmi <image name>
To remove an image.
9. docker pull <imagename>
Pulls an image. Logically if the image is not present and if we run a `docker run` command, it will pull the image if not found locally. This takes time and we can pull and keep an image locally if needed.
10. docker run <repository name>
Runs in the foreground
11. docker run -d <repository name>
Runs in the background.
12. docker attach <container ID>
This is used to attach to a container running in the background. To get the ID, use the `docker ps` command.
