If you already have a Jenkins server on which you want to use the plugin, you can skip to the Plugin Installation section. If not, you can either:

1. Download Jenkins at jenkins.io and run it directly with java -jar jenkins.war.
2. Create a Jenkins server on Amazon EC2 with AWS Marketplace.

Build AWS CodeBuild Jenkins plugin locally by running:

mvn install

This command will generate a aws-codebuild.hpi file which will be installed on your Jenkins server.

• In Jenkins, choose Manage Jenkins > Manage Plugins > Advanced > Upload Plugin > Browse (select the aws-codebuild.hpi file) > Upload to install the AWS CodeBuild plugin.

1. Create Project on the AWS CodeBuild console.
   • Switch to the region you would prefer to run the build in.
   • Make sure to write down the project's name.
2. Create AWS IAM user to be used by the Jenkins plugin.
   • Create a policy similar to the one following this section.
   • Go to the IAM console, and create a new user.
     • Access type should be: Programmatic Access.
     • Attach policy to user that you created previously.
3. Create a freestyle project in Jenkins.
   • On the Configure page, choose Add build step > Run build on AWS AWS CodeBuild.
   • Configure your build step.
     • Enter Region, Credentials from the user created previously, and ProjectName.
     • Select Use Project source.
     • Save the configuration and run a build from Jenkins.

Policy sample for IAM user:

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Resource": ["arn:aws:logs:{{region}}:{{awsAccountId}}:log-group:/aws/codebuild/{{projectName}}:*"],
            "Action": ["logs:GetLogEvents"]
        },
        {
            "Effect": "Allow",
            "Resource": ["arn:aws:s3:::{{outputBucket}}/*"],
            "Action": ["s3:GetObject"]
        },
        {
            "Effect": "Allow",
            "Resource": ["arn:aws:codebuild:{{region}}:{{awsAccountId}}:project/{{projectName}}"],
            "Action": ["codebuild:StartBuild",
                       "codebuild:BatchGetBuilds",
                       "codebuild:BatchGetProjects"]
        }
	]
}

To use AWS CodeBuild inside of a VPC the Jenkins plugin is going to pull the source from your repository inside of your VPC, zip it up and place the source into the Amazon S3 input bucket for the project you specified. To do this we need to make some modifications to the setup above.

1. Create an Amazon S3 bucket.

   • Bucket must be versioned.

2. Create Project on the AWS CodeBuild console.

   • Use Amazon S3 as the source type.
     • Use the bucket you created previously.
     • Specifiy an Amazon S3 object key.
   • Make sure to write down the project's name.

3. Create AWS IAM user to be used by the Jenkins plugin.

   • Create a policy similar to the one following this section.
   • Go to the AWS IAM console, and create a new user.
     • Access type should be: Programmatic Access.
     • Attach policy to user that you created previously.

4. Create a freestyle project in Jenkins.

• For the Source Code Management make sure to select how you would like to retrieve your source. You may need to install the GitHub Plugin to your Jenkins server.
• On the Configure page, choose Add build step > Run build on AWS CodeBuild.
• Configure the build step.
  • Enter Region, Credentials from the user created previously, and Project name.
  • Select Use Jenkins source.
  • Save the configuration and run a build from Jenkins.

        },

        },
        {

        }
