aws-architect v6.7.96

AWS Architect

A hardened orchestrator for deploying Lambda microservices and S3 backed websites to AWS, using best practices, and an SDK that handles every possible edge case, with a focus on safety.

This is an open source project managed by the Authress Engineering team.

Features

• Standardized CF template to deploy microservice to Lambda, API Gateway, Route 53, etc..
• Standardized CF template for S3 bucket hosting for a website
• Default configuration to automatically handle the creation of pull request deployments to test infrastructure before production
• Working templated sample and make.js file to run locally and CI build.
• Lambda/API Gateway setup for seamless integration.
• Automatic creation of AWS resources when using including:
  • Lambda functions
  • API Gateway resources
  • Environments for managing resources in AWS
  • S3 Buckets and directories
  • S3 static website hosting
• Developer testing platform, to run lambdas and static content as a local express Node.js service, to test locally. Integrates with OpenAPI-Factory

Usage

Library Functions

let packageMetadataFile = path.join(__dirname, 'package.json');
let packageMetadata = require(packageMetadataFile);

let apiOptions = {
  sourceDirectory: path.join(__dirname, 'src'),
  description: 'This is the description of the lambda function',
  regions: ['eu-west-1']
};
let contentOptions = {
  bucket: 'WEBSITE_BUCKET_NAME',
  contentDirectory: path.join(__dirname, 'content')
};
let awsArchitect = new AwsArchitect(packageMetadata, apiOptions, contentOptions);

// Package a directory in a zip archive and deploy to an S3 bucket, required for stage deployment and CF stack deployment
let options = {
  bucket: 'BUCKET_NAME'
};
publishLambdaArtifactPromise(options = {}) {...}

// Validate a cloud formation stack template using CloudFormation
validateTemplate(stackTemplate) {...}

// Deploy a Cloudformation template to AWS, should be used to create all the infrastructure required and run only on master branches
let stackConfiguration = {
  stackName: 'STACK_NAME'
  changeSetName: 'NAME_OF_CHANGE_SET'
};
let parameters = { /** PARAMETERS_FOR_YOUR_TEMPLATE, but also include these unless being overwritten in your template */
  serviceName: packageMetadata.name,
  serviceDescription: packageMetadata.description,
  dnsName: packageMetadata.name.toLowerCase()
};
deployTemplate(stackTemplate, stackConfiguration, parameters) {...}

// Deploy the stage of your microservice stack, to be called for each build in master or a pull-request.
publishAndDeployStagePromise(options) {
  // options.stage
  // options.functionName
  // options.deploymentBucketName
  // options.deploymentKeyName
}

// Deploy just a new version of a lambda function
deployLambdaFunctionVersion(options) {
  // options.stage
  // options.functionName
  // options.deploymentBucketName
  // options.deploymentKeyName
}

// Removes a deployed stage, to be used on pull-request created stages (API gateway has a limit fo 5 stages)
removeStagePromise(stage) {...}

// Creates a website, see below
publishWebsite(version, options) {...}

// Debug the running service on port at http://localhost:port/api
run(port, logger) {...}

Example: S3 Website Deployment

AWS Architect has the ability to set up and configure an S3 bucket for static website hosting. It provides a mechanism as well to deploy your content files directly to S3. Specify bucket in the configuration options for contentOptions, and configure the PublishWebsite function in the make.js file.

  awsArchitect.publishWebsite('deadc0de-1', options)
  .then((result) => console.log(`${JSON.stringify(result, null, 2)}`))
  .catch((failure) => console.log(`Failed to upload website ${failure} - ${JSON.stringify(failure, null, 2)}`));

  .promoteToStage('deadc0de-1', 'production')
  .then((result) => console.log(`${JSON.stringify(result, null, 2)}`))
  .catch((failure) => console.log(`Failed copying stage to production ${failure} - ${JSON.stringify(failure, null, 2)}`));

Configuration Options: Publishing the website has an options object which defaults to:

{
  // provide overrides for paths to change bucket cache control policy, default 600 seconds,
  cacheControlRegexMap: [
    { regex: '/index.html/', value: 'public, max-age=10' },
    { explicit: 'only.this.static.file', value: 'public, max-age=10' }
    { value: 'public, max-age=600' }
  ]
}

CLI: Creating a microservice: init

This will also configure your aws account to allow your build system to automatically deploy to AWS. Run locally

• Create git repository and clone locally
• npm install aws-architect -g
• aws-architect init
• npm install
• Update:
  • package.json: package name, the package name is used to name your resources
  • make.js: Deployment bucket, Resource, and DNS name parameters which are used for CF deployment

Built-in SAM and CFN templates:

See template service documentation for how individual parts of the service are configured.
