learning docker from amigoscourse

1. Image is a template for creating an environment of your choice
2. (docker pull imageName)
3. (docker images) - see the list of images
4. (docker run imagename)
5. (docker container ls) = (docker ps)
6. (docker run -d imageName) - run in detached mode
7. (docker stop containerID/container name)
8. (docker run -d -p 8080:80 imageName) -  80/TCP is the port no. of the container which can be seen in the docker ps, here we map the localhost 8080 to the port 80 of the container
   * We can access the image on webpage by entering localhost:8080
9. (docker run -d -p 8080:80 -p 3000:80 imageName) - can map multiple ports
10. (docker stop containerID/container name)
11. (docker ps -a) to show all the containers alongside that had stopped
12. (docker rm containername/id)
13. (docker ps -aq) - give only ids of all the containers
14. docker rm $(docker ps -aq) - delete the things given bt this command
15. (docker run --name containerName imageName) - we can manually name container instead of the random name given by pc
16. (export DOCKER_FORMAT="ID\t{{.ID}}\nNAME\t{{.Names}}\nImage\t{{.Image}}\nPORTS\t{{.Ports}}\nCOMMAND\t{{.Command}}\nCREATED\t{{.CreatedAt}}\nSTATUS\t{{.Status}}\n"
