On your journey of making a CI/CD pipeline on AWS with these tools, you completed AWS CodeCommit.

Next few days you'll learn these tools/services:

1. CodeBuild

2. CodeDeploy

3. CodePipeline

4. S3

What is CodeBuild?

AWS CodeBuild is a fully managed build service in the cloud. CodeBuild compiles your source code, runs unit tests, and produces artefacts that are ready to deploy. CodeBuild eliminates the need to provision, manage, and scale your build servers.

Task-01 :

• Read about the Buildspec file for Codebuild.

  A Buildspec file is a YAML file that defines the build process for your CodeBuild project. It contains a series of commands that CodeBuild will execute to build and package your application.

• Create a simple index.html file in CodeCommit Repository

• You have to build the index.html using the nginx server

CodeCommit

1. Log in to the AWS console and navigate to Codecommit > Create a repository

2. As we already created a repo in part 1, I am using the same repo and cloning it.

1. Connect to the instance and use the Git clone command

    $ git clone <your-codecommit-repo-clone-https-url>
   

2. Enter the HTTPS GIT Credentials that you created and downloaded from the code commit

   

3. Now create an index.html file inside the repo and commit it to repo

   

   

   

   Now check the repository on the CodeCommit, we should see the index.html file

Task-02 :

CodeBuild

1. Codebuild will be built from the CodeCommit repo files only.

2. Click on Build Projects> Create Build project

1. Provide the source details AWS CodeCommit and Repo/branch details

1. We need to create a service role so that CodeBuild can communicate with CodeCommit, CodeDeploy, S3, artifact and other resources

2. Select New service role and the Role name will be automatically provided

1. We are using Use a buildspec file to run the CodeBuild, so connect to the instance and write a buildspec

2. Buidspec is like a configuration file that specifies a set of commands to run

version: 0.2
phases:
  install:
    commands:
      - echo Installing NGINX
      - sudo apt-get update
      - sudo apt-get install nginx -y
  build:
    commands:
      - echo Build started on `date`
      - cp index.html /var/www/html/
  post_build:
    commands:
      - echo Configuring NGINX

artifacts:
  files:
    - /var/www/html/index.html

https://github.com/rjthapaa/AWS-DevOps-Project/blob/main/buildspec.yml

Artifacts are the storage location of our S3 bucket.

Now push this buildspec.yml from local to a CodeCommit.

Review the push changes in CodeCommit

Batch configuration and Artifacts / Cloud are optional

Leave the rest to defaults and Click on Create Build project

1. Our build project for Nginx is ready

1. Now click on Start build and check the status

1. You can check every phase in Phase details

1. Add the project source code to S3 Bucket using artifacts

Select the Build project and click on Edit > Artifacts

Create an s3 bucket of your choice

Type will be the storage location - Amazon S3 and provide the Bucket name of S3.

Give an output folder in the name section to store the buildspec

Select Packaging as None

Click on Update artifacts and start build again

The build got successful and the buildspec.yml will be updated in the selected s3 bucket

Let's move to the S3 bucket and check the directory of index.html

Index.html file is copied to the specified S3 bucket from the Code build.

Select the index.html file in the S3 bucket and click on open to access the server
