In the modern era, deploying the code on the multiple server is a challenging one. In classic, people normally use FTP\/SFTP to upload the files and restart application. In this article, we are gonna explain how to use code deploy aws service to deploy the code on aws instances.<\/p>\n

There are two ways to deploy the code to the instances.<\/p>\n

    \n
  1. Aws S3<\/li>\n
  2. Git Hub<\/li>\n<\/ol>\n

    We are going to cover how to deploy code from git hub. Incase if you want use, amazon s3, please refer amazon code deploy document.<\/p>\n

    Implementation:<\/h4>\n

    Let’s start with\u00a0IAM role creation. We need to create 2 IAM roles for the services ec2 and code deploy to communicate each other.<\/p>\n

      \n
    1. CodeDeployInstanceRole<\/li>\n
    2. CodeDeployServiceRole<\/li>\n<\/ol>\n

      Create a new Role(IAM > Create New Role <\/strong>). Enter the Role name as CodeDeployServiceRole <\/strong>and attach the below policy.<\/p>\n

      + AwsCodeDeployRole<\/p>\n

      Create another role. Enter the Role Name as CodeDeployInstanceRole <\/strong>and attach the below policy.<\/p>\n

      + AmazonEc2RolePolicyForAWSCodeDeploy
      \n+ AutoScalingNotificationAccessRole<\/p>\n

      <\/h5>\n
      Launching Instance with IAM Role:<\/h5>\n

      From previous step, we have created 2 policies and its time to use these policies at the time of instance launch.<\/p>\n

      While launching the instance, make sure to select “IAM role” <\/span><\/strong>as “CodeDeployInstanceRole” and complete the installation launch process. Please follow the below post to install LAMP, LEMP on the server which we have launched depends on your requirement.<\/span><\/p>\n

      Install apache, php5.6 ubuntu <\/a><\/p>\n

      Install Nginx, Php, MariaDB on Ubuntu 16.04.1<\/a><\/p>\n

      Install Dependency:<\/h5>\n

      In this example, we are using ubuntu host. Lets start with dependency installation.<\/p>\n

      apt-get -y install python-pip<\/code><\/code><\/p>\n

      apt-get -y install ruby<\/code><\/p>\n

      apt-get -y install wget<\/code><\/p>\n

      Download the codedeploy-agent install.<\/p>\n

      wget https:\/\/aws-codedeploy-eu-central-1.s3.amazonaws.com\/latest\/install<\/code><\/p>\n

      Install the application<\/p>\n

      chmod +x .\/install
      \n.\/install auto<\/code><\/p>\n

      Start the codedeploy-agent.<\/p>\n

      service codedeploy-agent start<\/code><\/p>\n

      Deployment Script:<\/p>\n

      Code deploy requires\u00a0appspec.yml\u00a0<\/em> files which is mandatory for codedeploy to work. Create appspec.yml and upload it in git repo. The sample configuration can be downloaded from the below URL.<\/p>\n

      appspec.yml<\/a><\/p>\n

       <\/p>\n

      version: 0.0\r\nos: linux\r\nfiles:\r\n  - source: \/\r\n    destination: \/var\/www\/html\r\n    except:\r\n    owner: ubuntu\r\n    group: ubuntu\r\npermissions:\r\n  - object: \/var\/www\/html\r\n    owner: ubuntu\r\n    group: ubuntu\r\n    mode: 755\r\n    type:\r\n      - directory\r\n  - object: \/var\/www\/html\r\n    owner: ubuntu\r\n    group: ubuntu\r\n    type:\r\n      - file\r\n\r\nhooks:\r\n  BeforeInstall:\r\n    - location: scripts\/install_codedeployment\r\n      timeout: 40\r\n      runas: root\r\n  ApplicationStart:\r\n    - location: scripts\/restart_nginx.sh\r\n      timeout: 30\r\nrunas: root\r\n<\/pre>\n
      Create a directory\u00a0scripts\u00a0<\/strong>on git and upload the following files on the git repository.<\/p>\n
      restart_nginx.sh<\/a><\/p>\n
       <\/p>\n
      \r\n#!\/bin\/bash\r\nservice nginx restart\r\n<\/pre>\n
      Create CodeDeploy Application:<\/h5>\n
      Login to Aws Management Console<\/p>\n
      Move the pointer to Services > CodeDeploy<\/strong><\/p>\n
      Select Create Application<\/strong><\/p>\n
      Add the application details<\/p>\n
      \n
      Application name<\/span><\/em>:<Your Application Name><\/em>
      \n<\/span><\/p>\n
      Deployment group name<\/span><\/em>:<Deployment Group Name>
      \n<\/span><\/p>\n
      Deployment type: In-Place Deployment<\/em><\/p>\n
      Add Instances:<\/em><\/p>\n
