Docker node.js mongodb authentication error

Was reading this: Using authenticationDatabase option while connecting to mongodb from nodejs

However it doesn't seem to help me.

I'm running all of the following commands in a Dockerfile. I Do the same setup on my local computer and it works, just no when building the container.

Start up mongod without auth to add users:

/usr/bin/mongod --fork --smallfiles --logpath /var/log/mongodb.log

Bash command to create users:

mongo insta /tmp/create_db.js

create_db.js file:

db.createUser(
    {
        user: "owner",
        pwd: "insta1",
        roles: [
            { role: "dbOwner", db: "insta" }
        ]
    }
);
db.createUser(
    {
        user: "normal",
        pwd: "insta1",
        roles: [
            { role: "readWrite", db: "insta" }
        ]
    }
);
db.createCollection("test");

Now I stop the mongod instance:

/usr/bin/mongod --shutdown

Start up mongod instance with auth:

/usr/bin/mongod --auth --fork --smallfiles --logpath /var/log/mongodb.log

I can connect with the following:

mongo -u normal -p insta1 --authenticationDatabase insta

Now I try to connect in node.js:

MongoClient.connect('mongodb://normal:insta1@127.0.0.1:27017/insta', async (error, db) => {
  console.log(error);
  //...more code
})

I get the error:

MongoError: Authentication failed

npm test is where it screws up. I don't really know where the error is?
