Execute a program within a docker, the easy way…

I know that you can just exec into the docker and run a program, but to do it from outside the docker?  (Using linux)

Inside docker you use:

docker exec -ti <dockername> /bin/bash

…and then:

ls -al /etc

Outside of the docker environment:

docker exec -ti <dockername> /bin/bash -c “ls -al /etc”

Another example to import a database into mysql:

docker exec -i <dockername> mysql -uroot -p<SECRET> < <FLENAME>.sql
