Ways to run a Docker container

1. To run a single task: This could be a shell script or a custom app.

docker container run alpine hostname

1. Interactively: This connects you to the container similar to the way you SSH into a remote server.

docker container run --interactive --tty --rm ubuntu bash

1. In the background: For long-running services like websites and databases.

docker container run \
 --detach \
 --name mydb \
 -e MYSQL_ROOT_PASSWORD=my-secret-pw \
 mysql:latest
