I'm new to Docker and struggling to use it with mongo and mongo_express. I found many StackOverflow posts about this issue, but none of them solved the problem I'm dealing with.
I'm making a website that requires a user login function, and usernames and passwords are supposed to be stored on mongod. However, it seems like my database server (node.js express) is not connected to the database that is located in another container. I think this is the reason why I receive this (MongooseServerSelectionError: getaddrinfo ENOTFOUND MongoDB).
Here is my docker-compose.yaml file, and express is node server, mongo is database, and mongo_express is a database management tool.
services:
express:
container_name: video-express

video_express_node:
And here is the connection part of server.js file.
mongoose.connect("mongodb://root:pass@mongodb:27017/videoUserDB", {
useNewUrlParser: true
});
If I connect to http://0.0.0.0:8081/db/admin/, I can open mongo-express page, so I assume the problem is the connection between server.js and mongod.
These are error messages I see now. There are some I cannot understand, but if you can identify the problem by these, that would be great.
