How to enable MongoDB authentication with docker-compose ?

efe136 profile image Efkan Isazade Updated on ・2 min read

By default there is no authentication in MongoDB. It means that it comes with empty authentication. So we should create users and roles manually. There are lots of ways to create MongoDB docker-compose with authentication. The most popular one of them is to write a bash script with user and roles then use it in docker-compose and another way is to create an init-mongodb.js file with users and roles and use it in docker-compose. But in this post, I will show you how you could create MongoDB docker-compose and then add users and roles manually. Lets start...

Run MongoDB docker-compose without authentication

First of all we should run MongoDB docker-compose without auth. Using docker-compose up -d we could run it.

Enable MongoDB auth in docker-compose

In order to enable auth in MongoDB we will use --auth flag in docker-compose. After that we could use docker-compose up -d command again, to run MongoDB container.

Connect MongoDB with defined authentication

In this step we can connect our db with defined authentication. Firstly again we need to run docker exec -it mongodb bash command in order to enter inside the container. Now we are in so we can connect our db. Here I write 2 command one of them is to connect admin db and another one is to connect demo db.

mongo -u root -p root --authenticationDatabase admin
mongo -u demo -p demo12345 --authenticationDatabase demo
