In my last blog<\/a>, we discussed how to setup MongoDB replica set on Docker, and in this blog we’ll be discussing setting up MongoDB docker containers using Chef. After going through this blog, you will be able to setup multiple MongoDB customized docker containers with ease.
\n\"mongodb_docker\"<\/p>\n

Use Case:<\/b>\u00a0As discussed in the previous blog, we earlier use to setup MongoDB replica set of three docker containers using custom shell scripts. So, I thought it would great\u00a0if we can use configuration manager tool like Chef for docker<\/a> deployments and management. In this blog, I will be demonstrating how you can deploy MongoDB docker containers using chef.<\/p>\n

Pre-requisite:<\/b>\u00a0Before going ahead with this blog prior knowledge of working with MongoDB, Docker and Chef basics are required.<\/p>\n

    \n
      \n
    1. Download docker cookbook using command as mentioned below:<\/li>\n<\/ol>\n<\/ol>\n

      [js]knife cookbook download docker[\/js]<\/p>\n

        \n
          \n
        1. Chef Recipe: To create docker image and launch mongo DB containers:<\/li>\n<\/ol>\n<\/ol>\n

          [js]# Using docker_service for installation and configuration
          \ndocker_service ‘default’ do
          \n action [:create, :start]
          \nend<\/p>\n

          # Create docker image, if image not found locally
          \ndocker_image ‘neerjaj2\/mongodb-docker’ do
          \n tag ‘v0.1.0’
          \n source ‘\/home\/ubuntu\/chef-repo\/cookbooks\/docker-mongodb\/files\/default\/Dockerfile’
          \n action :build_if_missing
          \nend<\/p>\n

          # Below code can be used to pull docker image from docker hub
          \n"docker_image ‘neerjaj2\/mongodb’ do
          \n action :pull
          \nend"<\/p>\n

          # Launch docker container using above mentioned docker image
          \ndocker_container ‘launch’ do
          \n repo ‘neerjaj2\/mongodb-docker’
          \n tag ‘v0.1.0’
          \n hostname ‘mongo1’
          \n domain_name ‘ttnd.com’
          \n publish_all_ports
          \n command ‘–replSet ttnd –noprealloc –smallfiles’
          \nend [\/js]<\/p>\n

          Note: You can either pull docker image from docker hub or create a custom image on every. In the above example, we are creating a new image using chef-repo\/cookbooks\/docker-Mongodb\/files\/default\/Dockerfile to customize every run.<\/h6>\n
            \n
              \n
            1. Contents of Dockerfile are:<\/li>\n<\/ol>\n<\/ol>\n

              [js]FROM ubuntu:latest
              \nRUN apt-key adv –keyserver hkp:\/\/keyserver.ubuntu.com:80 –recv 7F0CEB10
              \nRUN echo ‘deb http:\/\/downloads-distro.mongodb.org\/repo\/ubuntu-upstart dist 10gen’ | tee \/etc\/apt\/sources.list.d\/10gen.list
              \nRUN apt-get update
              \nRUN apt-get install -y mongodb-10gen=2.2.3
              \nRUN mkdir -p \/data\/db
              \nEXPOSE 27017
              \nENTRYPOINT ["usr\/bin\/mongod"]
              \n[\/js]<\/p>\n

                \n
                  \n
                1. Also add dependency in chef-repo\/cookbooks\/docker-mongodb\/metadata.rb, as shown below:<\/li>\n<\/ol>\n<\/ol>\n

                  [js]depends ‘docker’, ‘~> 1.0′[\/js]<\/p>\n

                    \n
                  1. So, let\u2019s execute chef recipe using command mentioned below:<\/li>\n<\/ol>\n
                      \n
                        \n
                      • To run chef recipe on localhost, use below mentioned command. In case you want to bootstrap remote host you can do that using knife bootstrap command.<\/li>\n<\/ul>\n<\/ul>\n

                        [js]chef-client -z -r \u201crecipe[docker-mongodb]\u201d[\/js]<\/p>\n

                        \"mongodb<\/p>\n

                        From the above screenshot, you can see our chef recipe created new docker image neerjaj2\/mongodb-docker and deployed a MongoDB container using the same.<\/p>\n

                          \n
                            \n
                          • Let us check Mongodb docker container hostname and MongoDB daemon status:<\/li>\n<\/ul>\n<\/ul>\n

                            \"mongodb
                            \nYou can now play around this chef recipe and use it as per your requirement.<\/p>\n","protected":false},"excerpt":{"rendered":"
