cd doodle/cheers2019 && docker build -t vinkrish/cheers2019 .
docker run -it --rm vinkrish/cheers2019
docker login && docker push vinkrish/cheers2019

Have Dockerfile and then:

docker container run --publish 80:80 nginx
docker container run --name nginx-server --publish 80:80 --detach nginx

docker container run -d --name mysql -e MYSQL_ALLOW_EMPTY_PASSWORD=True mysql

docker container inspect mysql

docker container run --name mysql-db --env MYSQL_RANDOM_ROOT_PASSWORD=yes --publish 3306:3306 --detach mysql

docker volume ls
docker container rm mysql mysql2
docker volume inspect __volume_name

docker container top mysql-db
