AWS CodeBuild Jenkins Plugin

The AWS CodeBuild plugin for Jenkins provides a build step for your Jenkins project.

Setup Jenkins

We have written a blog post for setting up Jenkins with AWS CodeBuild plugin pre-installed. Learn more: https://aws.amazon.com/blogs/devops/simplify-your-jenkins-builds-with-aws-codebuild/.

Plugin Installation (optional)

If you already have a Jenkins setup and would like to only install the AWS CodeBuild plugin, then the recommended approach would be to search for "AWS CodeBuild Plugin for Jenkins" in the Plugin Manager on your Jenkins instance.

Plugin Usage

Using AWS CodeBuild with source available outside of your VPC

  1. Create Project on the AWS CodeBuild console.

    • Switch to the region you would prefer to run the build in.
    • You can optionally set the Amazon VPC configuration to allow CodeBuild build container to access resources within your VPC.
    • Make sure to write down the project's name.
    • (Optional) If your source repository is not natively supported by CodeBuild, you can set the input source type for your project as S3 for the CodeBuild project.
  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.
  4. 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 (or the relevant source repository provider's Jenkins 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.

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:::{{inputBucket}}"],
            "Action": ["s3:GetBucketVersioning"]
        },
        {
            "Effect": "Allow",
            "Resource": ["arn:aws:s3:::{{inputBucket}}/{{inputObject}}"],
            "Action": ["s3:PutObject"]
        },
        {
            "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"]
        }
	]
}

Using the AWS CodeBuild plugin with the Jenkins Pipeline plugin

Use the snippet generator (click "Pipeline Syntax" on your pipeline project page) to generate the pipeline script that adds CodeBuild as a step in your pipeline. It should generate something like

awsCodeBuild projectName: 'project', credentialsType: 'keys', region: 'us-west-2', sourceControlType: 'jenkins'

Additionally, this returns a result object which exposes the following methods which can be useful to later steps:

  • getBuildId(): returns the build ID of the build (similar to codebuild-project-name:12346789-ffff-0000-aaaa-bbbbccccdddd)
  • getArn(): returns the ARN of the build (similar to arn:aws:codebuild:AWS_REGION:AWS_ACCOUNT_ID:build/CODEBUILD_BUILD_ID, where CODEBUILD_BUILD_ID is the same information returned in getBuildId)
  • getArtifactsLocation(): returns the S3 ARN of the artifacts location (similar to arn:aws:s3:::s3-bucket-name/path/to/my/artifacts)

AWS Credentials in Jenkins

When using credentialsType: 'keys' or creating new CodeBuild Credentials in Jenkins, the plugin will attempt to use the default credentials provider chain if AWS access and secret keys are not defined. If you are running Jenkins on an EC2 instance, leave the AWS Access Key and AWS Secret Key fields blank to use your EC2 instance profile.
