Access mongo shell running in docker container in linux script

Question

I want to create a bash script that removes a user from a mongodb database that is running inside a docker container.

Normally through the terminal I would execute docker exec -it mycontainername bash

and then once I'm in the container I execute mongo mydbname --eval "db.users.remove({"firstname":"Bob"})"

I just have no idea how to do it in a linux bash script.

After I execute script that contains the docker exec command, it leaves the script and opens the docker container's terminal and prompts me to enter a command.

Would using the detached -d flag work?

Answer 1

Found out you can replace bash with the name of the shell you want to open, so in this case mongo.
