A clustered mongoDB docker image allows you spinning up a mongoDB cluster in a few seconds.

This image is available on DockerHub in this link https://hub.docker.com/r/godois/mongodb-clustered/

• Shell script
• Docker

Note: The fastest way to get this application up and running locally is using Docker. Be sure that you have at least Docker 1.13.0 installed on your machine.

1. Clone this repository

$ git clone https://github.com/godois/clustered-mongodb-docker-image.git

2. Building the local image

You should execute the follow command in the project directory

$ docker build -t localhost/mongodb-clustered:1.0 .

You will need to run the follow steps to run a single node mongodb.

First, create a network in case of you need to communicate to another container. The name of the network defined is mongodb-net

$ docker network create --subnet=192.170.0.0/16 mongodb-net

So, run the following command:

$ docker run -d -it \
      --name mongodb-singlenode \
      --hostname="mongonode1.example.com" \
      --ip 192.170.1.1 \
      --net mongodb-net \
      -p 27017:27017 -p 28017:28017 \
      -e MONGODB_REPLICASET=false \
      -e MONGODB_MASTER=false \
      -e MONGODB_CLUSTER_NAME=false \
      -e MONGODB_ENDPOINTS=false \
      -v /tmp/mongodb-master/data:/opt/mongodb/data \
      -v /tmp/mongodb-master/log:/opt/mongodb/log \
      godois/mongodb-clustered:1.0

Explaining docker run parameters:

• --name - it defines the container name.
• --hostname - it sets up the hostname that will be visible to the network.
• --ip - it sets up the ip that will be visible to the network.
• --net - it defines the network which this container will be part of.
• -p - it binds the container port to the host port.
• -p - it binds the container port to the host port.
• -e - it allows you to send an environment variable to the container, which will be available into the entry-point shell script.
• -v - it binds the container file system to the host file system.

Note: Volumes are used to persist container data in the host. If you don´t do that, all information inside or generated by the container will be lost.
