Dockerised MongoDB cluster - DO NOT USE FOR PRODUCTION

Requirements

• Docker
• Docker Compose

Setup

• Update your device's hosts file with the following entries pointing to 127.0.0.1:

  • 127.0.0.1 mongo-node-1
  • 127.0.0.1 mongo-node-2
  • 127.0.0.1 mongo-node-3
  • 127.0.0.1 mongo-node-4
  • 127.0.0.1 mongo-node-5

• From a terminal, run ./start.sh. This will spin up 6 docker containers, 5 mongodb nodes and a mongo-express instance.

• You should be able to connect to the cluster with the connection string mongodb://mongo-node-1:27017,mongo-node-2:27018,mongo-node-3:27019,mongo-node-4:27020,mongo-node-5:27021/?replicaSet=rs0

• As an example, $ mongo mongodb://mongo-node-1:27017,mongo-node-2:27018,mongo-node-3:27019,mongo-node-4:27020,mongo-node-5:27021/?replicaSet=rs0
