CDK construct to create GitHub Actions self-hosted runners. A webhook listens to events and creates ephemeral runners on the fly.

/**
 * (experimental) Create all the required infrastructure to provide self-hosted GitHub runners.
 * 

* It creates a webhook, secrets, and a step function to orchestrate all runs. Secrets are not automatically filled. See README.md for instructions on how to setup GitHub integration. *

* By default, this will create a runner provider of each available type with the defaults. This is good enough for the initial setup stage when you just want to get GitHub integration working. *

*

 * new GitHubRunners(this, 'runners');
 * 
*

* Usually you'd want to configure the runner providers so the runners can run in a certain VPC or have certain permissions. *

*

 * const vpc = ec2.Vpc.fromLookup(this, 'vpc', { vpcId: 'vpc-1234567' });
 * const runnerSg = new ec2.SecurityGroup(this, 'runner security group', { vpc: vpc });
 * const dbSg = ec2.SecurityGroup.fromSecurityGroupId(this, 'database security group', 'sg-1234567');
 * const bucket = new s3.Bucket(this, 'runner bucket');
 * // create a custom CodeBuild provider
 * const myProvider = new CodeBuildRunnerProvider(
 *   this, 'codebuild runner',
 *   {
 *      labels: ['my-codebuild'],
 *      vpc: vpc,
 *      securityGroups: [runnerSg],
 *   },
 * );
 * // grant some permissions to the provider
 * bucket.grantReadWrite(myProvider);
 * dbSg.connections.allowFrom(runnerSg, ec2.Port.tcp(3306), 'allow runners to connect to MySQL database');
 * // create the runner infrastructure
 * new GitHubRunners(
 *   this,
 *   'runners',
 *   {
 *     providers: [myProvider],
 *   }
 * );
