Publish Buildkite webhook events to AWS SNS, enabling easy consumption by Lambda or other subscribers in the AWS ecosystem.

• Setup
• Examples
  • Basic
  • Custom domain

Usage

The webhook token should be stored as a secure string in AWS Systems Manager Parameter Store. To allow multiple tokens, use a comma separated list. This token is verified before publishing messages.

Multiple HTTP resources can be created. Each corresponds to a separate SNS topic.

SNS messages have an attribute "event" with the contents of X-Buildkite-Event. You may use this for subscription filter policies.

Inputs

Name	Type	Description	Default
deploy_version	string	Arbitrary version to force deployment of API gateway	"1"
endpoints	list	Names of endpoints	["all"]
name	string	Namespace for resources	"buildkite-events"
token_ssm_path	string	Parameter Store path to webhook token	-

Outputs

Name	Type	Description
gateway_api_id	string	ID of API gateway
gateway_invoke_url	string	URL of deployed API
gateway_stage_name	string	Stage name of API gateway
sns_topic_arns	list	ARNs of SNS topics

Requests can be made against "${gateway_invoke_url}/${endpoint}". (Or use a custom domain)

Examples

Basic

module "buildkite-events" {
  token_ssm_path = "/buildkite/webhook-token"
  source         = "github.com/rivethealth/terraform-aws-buildkite-events"
}

Custom domain

data "aws_acm_certificate" "buildkite-events" {
  domain   = "buildkite-events.example.com"
  statuses = ["ISSUED"]
}

module "buildkite-events" {
  token_ssm_path = "/buildkite/webhook-token"
  source         = "github.com/rivethealth/terraform-aws-buildkite-events"
}

resource "aws_api_gateway_base_path_mapping" "buildkite-events" {
  api_id      = "${module.buildkite-events.gateway_api_id}"
  stage_name  = "${module.buildkite-events.gateway_stage_name}"
  domain_name = "${aws_api_gateway_domain_name.buildkite-events.domain_name}"
}

resource "aws_api_gateway_domain_name" "buildkite-events" {
  certificate_arn = "${data.aws_acm_certificate.buildkite-events.arn}"
  domain_name     = "buildkite-events.example.com"
}

Note that a custom domain name will not be ready for several minutes.
