mongodb-replicaset

Simple replica set in docker with a web app to connect to it

An example of how to create a very simple replica set using docker's docker-compose file. It can be used for starting developing your app without needing to install a mongo server locally.

For starting this up

Just use:

docker-compose up

Url for the different mongo containers

• mongodb://mongo-rs0-1
• mongodb://mongo-rs0-2
• mongodb://mongo-rs0-3

Some commands for experimenting with the replica set

• docker exec mongodb-replicaset_mongo-rs0-1_1 bash -c 'mongo --eval "rs.status();"'
• docker stop mongodb-replicaset_mongo-rs0-2_1
• docker start mongodb-replicaset_mongo-rs0-2_1
