MongoDB

A clustered example of MongoDB running via docker. I made this so I can get used to some basic mongodb administration and maintenance stuff.

Getting Started

The mongodb service will forward it's published port to host port 27017. Make sure the port is not in use or change it to a different port.

Setup your mongodb cluster

Put user creation scripts in the provisioner/users directory

// Example
// provisioner/users/users.js

db.createUser({
  user: "admin",
  pwd: "password",
  roles: [{
    role: "dbOwner",
    db: "admin"
  }]
});

db.createUser({
  user: "client",
  pwd: "password",
  roles: ["readWriteAnyDatabase"]
});

db.createUser({
  user: "read-only",
  pwd: "password",
  roles: ["readAnyDatabase"]
});

Provision clustered and authenticated mongodb

# Start mongo with no authentication
docker-compose -f docker-compose-no-auth.yml up -d mongodb
# Run the provisioner to configure the cluster
docker-compose -f docker-compose-no-auth.yml up provisioner.mongodb
# Stop and remove the mongodb containers with no authentication
docker-compose down

You can find this and other helper scripts in the scripts directory.

Start mongodb

docker-compose up mongodb

Connect to your mongodb cluster using authentication

mongo mongodb://read-only:password@localhost:27017/admin?authSource=admin

To backup your database

docker-compose up backup.mongodb
