No such container found when running docker exec service

When I run this command, I receive the following error:

Error: No such container: service

What could be the problem? A quick google does not give any answers.

Have you built the containers with docker-compose build? What does docker image ls show?

This is the snapshot of docker image ls

I used the steps of the ODK guide for digital ocean which indeed includes docker-compose build.

I cant upgrade the server either with git pull. Perhaps I deleted some crucial files...

The command on newer versions of Central will be docker exec central_service_1 sh -c "find /tmp/tmp-* -type f -mmin +60 -delete";

That said, you shouldn't need to run this command because newer version of Central don't have the bug the command fixes.
