Docker CLi Cheatsheet that could follow when I forget about the basic commands :)
Docker Pull
- docker build image by Dockerfile
#docker build -t <image_name>:<tag> .

docker rmi ubuntu:22.04
Docker Container
# docker build container via image & run it via interactive mode
docker run -it --name my-ubuntu ubuntu:22.04 bash
# docker run on daemon mode, host:container port matching
docker run -d --name my-nginx -p 8080:80 nginx
# show all running docker containers
docker ps

docker ps -a
# docker start/stop/restart container <container_name>
docker start my-ubuntu
docker stop my-ubuntu
docker restart my-ubuntu
