Container commands

Container commands enable us to start, stop, and restart containers, execute commands upon them, and also kill them.

exec

Throughout the book, we have executed commands using the Docker exec command. Docker Compose also provides this functionality.

$ docker compose exec task-manager ls
go.mod    go.sum    main.go         

If we check the existing containers, we will not see any extra containers provisioned:

$ docker ps -a
