How to run mongo in docker and restore dump there

There are cases happening quite often when you wanna check some functionality against data array provided from somewhere via mongodump utility. You may want to run some local server or just run some handcrafted queries. If you do not have mongodb installed locally then running it in docker sounds like a best way for me. So let's get our hands dirty a bit. Not too much luckily.

So first let's pull suitable mongodb docker image.

copied bash

docker pull mongo:4.2-bionic

Next let's run the container on some available port. In my case I did it on 8091 but we can use anything we want

copied bash

docker run --name test-mongo -d -rm -p 8091:27017 mongo:4.2-bionic

So now we have our mongo running and waiting for data being loaded there. To restore the dump we'll use mongorestore utility. There are several ways to get it installed on our system but I like have it as part of mongodb-database-tools. Go ahead to official docs and install the tools.

Other option to run mongo instance is to leverage docker-compose. For this create file docker-compose.mongo-dev.yml with content:

copied yaml

services:
  db:
    image: mongo:4.2-bionic
    volumes:
      - tmp_mongo_db-volume:/data/db
    ports:
      - 8091:27017

volumes:
  tmp_mongo_db-volume:

To spin up container run followin command:

copied bash

docker-compose -f docker-compose.mongo-dev.yml up -d

And now you can connect to your running mongo instance via whatever mongo client you use. I prefer studio3t.

After that we can run mongorestore command pointing to our local running docker container with mongodb server.

copied bash

mongorestore --host localhost --port 8091 --db some_collection ~/path/to/dump/some_collection
