Create Multiple Builds from the Same Source Using Different AWS CodeBuild Build Specification Files

In June 2017, AWS CodeBuild announced you can now specify an alternate build specification file name or location in an AWS CodeBuild project.

In this post, I’ll show you how to use different build specification files in the same repository to create different builds. You’ll find the source code for this post in the GitHub repo.

Requirements

The AWS CLI must be installed and configured.

Solution Overview

I have created a C program (cbsamplelib.c) that will be used to create a shared library and another utility program (cbsampleutil.c) to use that library. I’ll use a Makefile to compile these files.

I need to put this sample application in RPM and DEB packages so end users can easily deploy them. I have created a build specification file for RPM. It will use make to compile this code and the RPM specification file (cbsample.rpmspec) configured in the build specification to create the RPM package. Similarly, I have created a build specification file for DEB. It will create the DEB package based on the control specification file (cbsample.control) configured in this build specification.

RPM Build Project:

The following build specification file (buildspec-rpm.yml) uses build specification version 0.2. As described in the documentation, this version has different syntax for environment variables. This build specification includes multiple phases:

  • As part of the install phase, the required packages is installed using yum.
  • During the pre_build phase, the required directories are created and the required files, including the RPM build specification file, are copied to the appropriate location.
  • During the build phase, the code is compiled, and then the RPM package is created based on the RPM specification.

As defined in the artifact section, the RPM file will be uploaded as a build artifact.

version: 0.2

env:
	 variables:
	 	 build_version: "0.1"

phases:
  install:
	 	commands:
	 	 	- yum install rpm-build make gcc glibc -y
	pre_build:
	 	commands:
	 	  - curr_working_dir=`pwd`
	 	  - mkdir -p ./{RPMS,SRPMS,BUILD,SOURCES,SPECS,tmp}
	 	  - filename="cbsample-$build_version"
	 	  - echo $filename
	 	  - mkdir -p $filename
	 	  - cp ./*.c ./*.h Makefile $filename
	 	  - tar -zcvf /root/$filename.tar.gz $filename
	 	  - cp /root/$filename.tar.gz ./SOURCES/
	 	  - cp cbsample.rpmspec ./SPECS/
	build:
	 	commands:
	 	 	- echo "Triggering RPM build"
	 	 	- rpmbuild --define "_topdir `pwd`" -ba SPECS/cbsample.rpmspec
	 	 	- cd $curr_working_dir

artifacts:
	files:
	 	- RPMS/x86_64/cbsample*.rpm
	discard-paths: yes

Using cb-centos-project.json as a reference, create the input JSON file for the CLI command. This project uses an AWS CodeCommit repository named codebuild-multispec and a file named buildspec-rpm.yml as the build specification file. To create the RPM package, we need to specify a custom image name. I’m using the latest CentOS 7 image available in the Docker Hub. I’m using a role named CodeBuildServiceRole. It contains permissions similar to those defined in CodeBuildServiceRole.json. (You need to change the resource fields in the policy, as appropriate.)

After the cli-input-json file is ready, execute the following command to create the build project.

$ aws codebuild create-project --name CodeBuild-RPM-Demo --cli-input-json file://cb-centos-project.json

}

When the project is created, run the following command to start the build. After the build has started, get the build ID. You can use the build ID to get the status of the build.

DEB Build Project:

In this project, we will use the build specification file named buildspec-deb.yml. Like the RPM build project, this specification includes multiple phases. Here I use a Debian control file to create the package in DEB format. After a successful build, the DEB package will be uploaded as build artifact.

	 	 	 - dpkg-deb --build ./cbsample-$build_version

	 files:
	 	 - cbsample-*.deb<

Here we use cb-ubuntu-project.json as a reference to create the CLI input JSON file. This project uses the same AWS CodeCommit repository (codebuild-multispec) but a different buildspec file in the same repository (buildspec-deb.yml). We use the default CodeBuild image to create the DEB package. We use the same IAM role (CodeBuildServiceRole).

	 	 	 	 	 	 "key": "Name",
	 	 	 	 	 	 "value": "Debian Demo Build"
	 	 	 	 }
	 	 ]
}

Using the CLI input JSON file, create the project, start the build, and check the status of the project.

$ aws codebuild create-project --name CodeBuild-DEB-Demo --cli-input-json file://cb-ubuntu-project.json

$ aws codebuild list-builds-for-project --project-name CodeBuild-DEB-Demo

$ aws codebuild batch-get-builds --ids CodeBuild-DEB-Demo:e535c4b0-7067-4fbe-8060-9bb9de203789

After successful completion of the RPM and DEB builds, check the S3 bucket configured in the artifacts section for the build packages. Build projects will create a directory in the name of the build project and copy the artifacts inside it.

$ aws s3 ls s3://codebuild-demo-artifcat-repository/CodeBuild-RPM-Demo/
2017-07-20 16:16:59 	 	 	 8108 cbsample-0.1-1.el7.centos.x86_64.rpm

$ aws s3 ls s3://codebuild-demo-artifcat-repository/CodeBuild-DEB-Demo/
2017-07-20 16:37:22 	 	 	 5420 cbsample-0.1.deb

Override Buildspec During Build Start:

It’s also possible to override the build specification file of an existing project when starting a build. If we want to create the libs RPM package instead of the whole RPM, we will use the build specification file named buildspec-libs-rpm.yml. This build specification file is similar to the earlier RPM build. The only difference is that it uses a different RPM specification file to create libs RPM.

Using the same RPM build project that we created earlier, start.

$ aws codebuild start-build --project-name CodeBuild-RPM-Demo --buildspec-override buildspec-libs-rpm.yml
{
	 	 "build": {
	 	 	 	 "buildComplete": false,	
	 	 	 	 "initiator": "prakash",	
	 	 	 	 "artifacts": {
	 	 	 	 	 	 "location": "arn:aws:s3:::codebuild-demo-artifcat-repository/CodeBuild-RPM-Demo"
	 	 	 	 },	
	 	 	 	 "projectName": "CodeBuild-RPM-Demo",	
	 	 	 	 "timeoutInMinutes": 15,	
	 	 	 	 "buildStatus": "IN_PROGRESS",	
	 	 	 	 "environment": {
	 	 	 	 	 	 "computeType": "BUILD_GENERAL1_SMALL",	
	 	 	 	 	 	 "privilegedMode": false,	
	 	 	 	 	 	 "image": "centos:7",	
	 	 	 	 	 	 "type": "LINUX_CONTAINER",	
	 	 	 	 	 	 "environmentVariables": []
	 	 	 	 },	
	 	 	 	 "source": {
	 	 	 	 	 	 "buildspec": "buildspec-libs-rpm.yml",	
	 	 	 	 	 	 "type": "CODECOMMIT",	
	 	 	 	 	 	 "location": "https://git-codecommit.eu-west-1.amazonaws.com/v1/repos/codebuild-multispec"
	 	 	 	 },	
	 	 	 	 "currentPhase": "SUBMITTED",	
	 	 	 	 "startTime": 1500562366.239,	
	 	 	 	 "id": "CodeBuild-RPM-Demo:82d05f8a-b161-401c-82f0-83cb41eba567",	
	 	 	 	 "arn": "arn:aws:codebuild:eu-west-1:012345678912:build/CodeBuild-RPM-Demo:82d05f8a-b161-401c-82f0-83cb41eba567"
	 	 }
}

After the build is completed successfully, check to see if the package appears in the artifact S3 bucket under the CodeBuild-RPM-Demo build project folder.

$ aws s3 ls s3://codebuild-demo-artifcat-repository/CodeBuild-RPM-Demo/
2017-07-20 16:16:59 	 	 	 8108 cbsample-0.1-1.el7.centos.x86_64.rpm
2017-07-20 16:53:54 	 	 	 5320 cbsample-libs-0.1-1.el7.centos.x86_64.rpm

Conclusion

In this post, I have shown you how multiple buildspec files in the same source repository can be used to run multiple AWS CodeBuild build projects. I have also shown you how to provide a different buildspec file when starting the build.

For more information about AWS CodeBuild, see the AWS CodeBuild documentation. You can get started with AWS CodeBuild by using this step by step guide.
