Installing and deploying a MongoDB cluster in Docker

Installing MongoDB in Docker

MongoDB image in use: https://registry.hub.docker.com/u/tutum/mongodb/

Start a container with this image (note that MongoDB is standalone mode at this point):

Docker run-d--name=mongodb-p 27017:27017-p 28017:28017 tutum/mongodb:3.0

Docker logs MongoDB

Output information:

========================================================================

You can now connect to the this MongoDB server using:

MONGO admin-u admin-p 5elst6ktjrqv--host

Remember to change the above password as soon as possible!

========================================================================

MONGO Admin-u admin-p 5ELST6KTJRQV

# set a password for admin when running a container

Docker run-d--name=mongodb-p 27017:27017-p 28017:28017-e mongodb_pass= "Mypass" Tutum/mongodb

# Set empty password when running a container

Docker run-d--name=mongodb-p 27017:27017-p 28017:28017-e auth=no Tutum/mongodb

# login MongoDB and Change password

MONGO admin-u admin-p vjq6u0dshdn7--host

> Db.changeuserpassword ("USERNAME", "PASSWORD")

Deploying a MongoDB cluster in Docker

Start the MongoDB container (all nodes) in Replset mode:

Docker run-d--name mongodb-p 27017:27017-p 28017:28017 tutum/mongodb:3.0 mongod--replset "Rs0"

Log in to the container, connect to MongoDB, and create the cluster: (only on the primary node)

Docker exec-it Mongodb/bin/bash

Mongo

> Rs.initiate ()

> rs.add ("node002.example.com")
> rs.add ("node003.example.com")

> rs.status ()
