Runway is a lightweight wrapper around infrastructure deployment (e.g. CloudFormation, Terraform, Serverless) & linting (e.g. yamllint) tools to ease management of per-environment configs & deployment.
AWS Cloud Development Kit (CDK)¶
The CDK module type is deployed using the AWS Cloud Development Kit (CDK). Runway uses system installed npm to install the CDK per-module. This means that the CDK must be included as a dev dependency in the package.json of the module.
CloudFormation & Troposphere¶
The CloudFormation module type is deployed using Runway’s CloudFormation engine (CFNgin). It is able to deploy raw CloudFormation templates (JSON & YAML) and Troposphere templates that are written in the form of a Blueprints.
Kubernetes manifests can be deployed via Runway offering an ideal way to handle core infrastructure-layer (e.g. shared ConfigMaps & Service Accounts) configuration of clusters by using Kustomize overlays.
The Serverless module type is deployed using the Serverless Framework. Runway uses system installed npm to install Serverless per-module. This means that Serverless must be included as a dev dependency in the package.json of the module.
This module type performs idempotent deployments of static websites. It combines CloudFormation stacks (for S3 buckets & CloudFront Distribution) with additional logic to build & sync the sites.
A start-to-finish example walkthrough is available in the Conduit quickstart.
The CloudFront Distribution that is created by default can take a significant amount of time to spin up on initial deploy (5 to 60 minutes is not abnormal). Incorporating CloudFront with a static site is a common best practice, however, if you are working on a development project it may benefit you to add the staticsite_cf_disable parameter.
Runway provides a simple way to run the Terraform versions you want with variable values specific to each environment. Terraform does not need to be installed prior to using this module type. Runway maintains a cache of Terraform versions on a system, downloading and installing different versions as needed.
