Introducing Replicasets

The way to achieve fault tolerance in MongoDB is through the use of replica sets.

stateDiagram-v2 [*] --> Application direction LR state Application Application --> replicaset state replicaset { direction RL Primary:primary Secondary1:secondary Secondary2:secondary Secondary1-->Primary : Fetch Oplog Secondary2-->Primary : Fetch Oplog }

Two or more secondary nodes along with a primary node forms a replica set. Application makes all the read/write calls to the primary node which propagate all the write requests synchronously or asynchronously to the secondary nodes.

The Secondary nodes fetches the data via Oplog pull from Primary or other nodes.

The solution to address this problem was to have a Domain Name System for the local network, which works to resolve local and external addresses with a reverse proxy to redirect calls based on DNS resolution.

In this article we will see the steps required to create and configure MongoDB replicaset containers on persistent volumes using Docker Compose. Compose was developed to define, configure and spin-up multi-container docker applications with single command, further reducing . Extensive usage of Docker with several container management quickly becomes cumbersome, Compose overcomes this problem and allows to easily handle multiple containers at once using YAML configuration docker-compose.yml

Docker Containers offer easy setup, customization and scalability. In this article, i will walk you through how to use Docker to setup MongoDB standalone and replica set containers within minutes.

The article is divided in two parts, the first part is setting up the standalone MongoDB container and second part is setting up and grouping MongoDB containers as member of replica set with Docker.

Let’s get started.
