Why use AWS CodeBuild for Continuous Delivery in Ruby on Rails application?

There are several reasons why one should use AWS CodeBuild for Continuous Delivery. Firstly, AWS CodeBuild is a fully managed build service that eliminates the need for you to manage your own build infrastructure. This means that you can focus on developing your application without worrying about the underlying infrastructure required to build and test your code. Additionally, AWS CodeBuild is highly scalable and can handle builds of any size, from small applications to large enterprise applications.

Secondly, AWS CodeBuild integrates seamlessly with other AWS services such as AWS CodePipeline and AWS Elastic Beanstalk, allowing you to create a fully automated continuous delivery pipeline. AWS CodePipeline is a continuous delivery service that automates the release process for your application, while AWS Elastic Beanstalk is a fully managed service that makes it easy to deploy and scale web applications. By integrating these services with AWS CodeBuild, you can automate the entire software development process, from code changes to production deployment.

Finally, AWS CodeBuild is highly customizable and supports a wide range of programming languages and build tools. This means that you can use AWS CodeBuild to build and test applications written in any language, using any build tool. Additionally, AWS CodeBuild allows you to customize your build environment by specifying the operating system, runtime, and build tools that you want to use. This level of customization ensures that your build environment is tailored to your specific needs, allowing you to build and test your application more efficiently.

Prerequisites

To complete the "AWS CodeBuild Continuous Delivery for Ruby on Rails" tutorial, you will need the following prerequisites:

1. An AWS account: You will need an AWS account to access the AWS services required for this tutorial.

2. A Ruby on Rails application: You should have a Ruby on Rails application that you want to deploy using AWS CodeBuild.

3. AWS Command Line Interface (CLI): You will need to install the AWS CLI on your local machine to interact with AWS services.

4. Git: You should have Git installed on your local machine to clone the sample application and push changes to your repository.

5. Docker: You will need to install Docker on your local machine to build and test your application using AWS CodeBuild.

6. AWS Elastic Beanstalk Command Line Interface (EB CLI): You will need to install the EB CLI on your local machine to deploy your application to AWS Elastic Beanstalk.

7. Basic knowledge of AWS services: You should have a basic understanding of AWS services such as AWS CodeBuild, AWS CodePipeline, and AWS Elastic Beanstalk.

Ruby on Rails AWS CodeBuild step by step setup and configuration

Integrating AWS CodeBuild into a Ruby on Rails project involves several steps. First, you need to create a build specification file that defines the build environment and commands to build and test your application. To create a build specification file, create a file named buildspec.yml in the root directory of your project and add the following code:

version: 0.2

phases:
  install:
    runtime-versions:
      ruby: 2.7
    commands:
      - echo Installing dependencies...
      - bundle install --path vendor/bundle
  build:
    commands:
      - echo Building application...
      - bundle exec rake assets:precompile
      - bundle exec rake db:migrate
  post_build:
    commands:
      - echo Build completed on `date`
artifacts:
  files:
    - '**/*'

This build specification file specifies the Ruby version, installs dependencies, builds the application, and creates an artifact that includes all files in the project directory.

Next, you need to create a CodeBuild project in the AWS Management Console. To create a CodeBuild project, navigate to the CodeBuild console, click on "Create build project", and configure the project settings. You will need to specify the source code location, build specification file location, and build environment settings. Once you have created the project, you can run a build by clicking on "Start build" in the CodeBuild console.

To integrate CodeBuild with other AWS services such as CodePipeline and Elastic Beanstalk, you can use the AWS CLI to create and configure the necessary resources. For example, to create a CodePipeline pipeline that uses CodeBuild to build and test your application, you can use the following AWS CLI command:

aws codepipeline create-pipeline --cli-input-json file://pipeline.json

This command creates a pipeline that uses CodeBuild as a build provider and deploys the application to Elastic Beanstalk.

Finally, you can deploy your application to Elastic Beanstalk using the EB CLI. To deploy your application, navigate to the root directory of your project and run the following command:

eb deploy

This command packages and deploys your application to Elastic Beanstalk, where it can be accessed by users.

AWS CodeBuild configuration options in Ruby on Rails

Here are the AWS CodeBuild configuration options for Ruby on Rails integration:

1. image: The Docker image to use for the build environment. For Ruby on Rails, you can use an image that includes Ruby and other required dependencies.

2. compute-type: The compute type to use for the build environment. This determines the amount of CPU and memory allocated to the build environment.

3. environment-variables: Environment variables to set in the build environment. For Ruby on Rails, you may need to set environment variables such as RAILS_ENV and DATABASE_URL.

4. phases: The build phases to run, such as install, pre_build, build, and post_build. For Ruby on Rails, you may need to run commands to install dependencies, build the application, and run tests.

5. artifacts: The artifacts to create and upload to S3. For Ruby on Rails, you may want to create an artifact that includes the compiled assets and database migrations.

6. cache: The cache settings to use for the build environment. This can improve build performance by caching dependencies and other files between builds.

7. service-role: The AWS Identity and Access Management (IAM) role to use for the build environment. This role determines the permissions that the build environment has to access AWS services.

8. source: The source code location for the build. For Ruby on Rails, you can use a Git repository or an S3 bucket to store the source code.

9. timeout: The maximum amount of time allowed for the build to complete. If the build exceeds this time limit, it will be terminated.

10. encryption-key: The AWS Key Management Service (KMS) key to use for encrypting artifacts and logs. This can help ensure the security of your build artifacts and logs.
