gci is a CI dispatching/status handling tool to integrate AWS CodeBuild with GitHub Push/Pull-Request webhook events, created with love of Serverless Architecture.

Yay, Serverless!

Pull Request:

• Invoking a pre-configured AWS CodeBuild project by hooking Push or Pull Reqeust webhook events.
• Setting GitHub's CI status based on status/result of builds on AWS CodeBuild.

gci allows you to provision multiple installations in one AWS account as follows:

As mentioned above, gci can be installed as many as you want to integrate with your GitHub repositories. If you want to build 3 repositories, you may provision 3 of gci installation for instance.

GitHub has a feature to show each commit's status like 'success', 'failure', 'pending' on their Commit/PR pages, and based on that status, we can protect any branches from CI failed branch to be merged.

GitHub accepts status creation via their APIs and many third-party CI services implement functionalities to integrate with that APIs to show their job status on GitHub.

On the other hand, AWS CodeBuild doesn't have such a feature to save its build project status to GitHub for now. gci is a missing piece of AWS CodeBuild to make things better. I heard that AWS CodeBuild now supports for building by GitHub push/PR and for updating GitHub status natively. We'll find another motivation to keep developing gci 😛

gci requires the following to be installed on your AWS account.

We use a Makefile to manage gci's lifecycle.

• GNU Make (if you are using macOS,brew install make is handy)

The Makefile depends on the following tools:

• Node.js v14.1.0 or later
• Yarn 1.22.0 or later
• AWS-CLI 1.11.132 or later
• curl

• AWS Account
• AdministratorAccess to your AWS Account (to use AWS CloudFormation in the installation command)
• GitHub Account

And the listed resources below are created in the process of installation, which means they are required as available AWS services in a region where you want to run gci.

• Amazon S3
• Amazon SNS
• Amazon CloudWatch Events
• AWS Lambda
• AWS CodeBuild
• AWS IAMv
• AWS CloudFormation

NOTE: Make sure you already have:
-AWS credentials for AWS CLI access.
- at least one AWS CodeBuild project created.

Create an S3 Bucket to store gci's artifacts to proceed.

$ aws s3api create-bucket \    --bucket {YOUR_S3_BUCKET_NAME} \    --create-bucket-configuration LocationConstraint=$AWS_DEFAULT_REGION

NOTE: Create an S3 bucket for each AWS region if you use gci in multiple AWS regions.

$ git clone https://github.com/toricls/github-codebuild-integration.git$ cd $(pwd)/github-codebuild-integration

OpenNew personal access token page and create one for a gci's installation.

Input token description likecodebuild-YOUR_REPO_NAME and enableadmin:repo_hook andrepo:status as scopes, then click theGenerate token button.

Copy the personal access token value and proceed to the next section, "Configure parameters".

Copy example configuration file and edit it to configure paramters for your GitHub repository.

$ export YOUR_PROJECT_NAME=xxxxxxxxxxxxxxxxx$ cp env/example.env env/$YOUR_PROJECT_NAME.env$ editor env/$YOUR_PROJECT_NAME.env

Next table describes about all available parameters of gci.

Package all artifacts and deploy to your AWS account. You can use this command to update your existing gci installation.

$ make deploy ENV_FILE_PATH=env/$YOUR_PROJECT_NAME.env

You can delete most of generated resources by executing:

$ make destroy ENV_FILE_PATH=env/YOUR-PROJECT-NAME.env

NOTE: CloudFormation doesn't delete CloudWatch's Log Groups. You may want to remove it manually on the AWS Management Console or via the AWS CLI. Also you may want to remove the S3 Bucket(s) you created.

Q. My IAM role is too weak to install your tool, I guess.

A. Ask your administrator and show him/her the following:

• Required Accounts & Resources section
• This tool uses CloudFormation with--capabilities "CAPABILITY_IAM" option

Q: I want to remove all resources of gci from my AWS account.

A: Read theUninstall section above :X

Q: I changed my repository name after gci install.

A: Change the value ofGITHUB_REPOSITORY_URL in your env file, then deploy again.

Q: I want to stop CI invoking for a bit.

A: OpenGitHubWebhookHandler function (the function name on the Lambda Management Console may something likeYOUR-PROJECT-NAME-GitHubWebhookHandler-XXXXXXXXXXX), then settrue to the environment variableDO_NOT_RUN.
Don't forget to back that value tofalse after your quick work.

Q: I need more than one AWS CodeBuild project for my GitHub repository.

A: I totally agree with you! It will be supported in the future. I think the feature will be implemented with a mapping configuration for 'branch name reg-expressions' and 'AWS CodeBuild projects'. But PRs are always welcome 😃

Q. Can you change the icon which shown at PR page's CI status?

A. GitHub shows the avatar of the user who owns the personal access token you provided. You can change the icon by using something likeMachine users to create a personal access token for gci.
