Connecting to MongoDB

An example of how you would connect to MongoDB and perform basic CRUD operations.

Requirements

• MongoDB version 4 and above.

Setup

1. Launch a shell session and start MongoDB (server) via Docker:

   $ docker-compose up
   

2. You can connect to Mongo via the console:

   $ docker exec -it mongo mongo -u nobody -p secrets go-recipes
   

3. You can press CTRL-C and CTRL-D on the mongo-server and mongo-cli respectively to stop the containers. Don't forget to remove the containers as well.

   $ # This should remove both mongo-server and mongo-cli
   $ docker-compose down
   

4. Run Go programL

   $ go run ./main.go
   

5. Alternatively, you can run everything with the following command.

   $ make
   

Notes

• We deliberately hard code the password to connect to MongoDB to keep the sample code simple and easy to understand. Do not do this in your code, especially production code.
