porter

porter is a platform built on AWS APIs to enable continuous delivery of Docker containers to EC2.

Lots of useful documentation is built into porter itself.

Run porter help, and most porter commands with no arguments for details on how to call them.

Features

  • Interactive command line interface (CLI) packaged as a statically linked binary
  • Multi-region, multi-AZ, blue-green deployments
  • Secrets management
    • S3 with SSE-KMS or bring your own secrets storage
  • Works in EC2-Classic, Default VPC, and Custom VPCs
  • Highly customizable
    • Programmable deployment pipeline and EC2 host-level customizations to help with everything from testing to client side deployments
    • Customizable AWS infrastructure by overriding any part of the default CloudFormation template
  • Rapidly bootstrap an empty AWS account with porter bootstrap commands
  • Easily integrates with any CI/CD software
  • Easy to adopt and unobtrusive
  • Allows developers to provision a single-region stack using the same CloudFormation template used in other environments to verify feature and bug fixes without needing to integrate in a shared environment (e.g. QA2)
  • Configurable deployment blackout windows

Project fit

Porter is a great fit for a lot of different projects, and not a great fit for others. Here's some examples of each

Good fit

  • Typical single-tenant N-tier services
  • Projects practicing continuous delivery
  • Dockerized, 12factor services
  • Teams wanting to use AWS that don't have the resources to build a deployment pipeline but find CodePipeline, CodeDeploy, ECS, and ElasticBeanstalk too constraining.
  • Mid-large companies / operations teams
    • Possibly with a multiple AWS accounts
    • Looking to provide a PaaS (porter + CI/CD + automated onboarding == PaaS)
    • Wanting to prevent "CI snowflakes": service-specific one-off logic baked into CI jobs. Porter's CI integration surface area is intentionally very small.
  • Multi-region services
  • Client applications (SPA, web-deployed clients) with a backend service
    • Have OAuth2 flows? porter create-stack can help
  • Projects looking to vastly simplify host provisioning (burn your cookbooks)

Poor fit

  • Mid-large projects consisting of many microservices, or projects needing the cost efficiency of clustering technologies (e.g. DCOS, Kubernetes)
  • Projects that manually release software. Porter was born and bred to support a fully automated CD environment. That said it is possible to add manual verification steps to a porter deployment.
  • Entirely stateless services (not even in-memory caching) - consider Lambda
  • Projects needing cloud-agnostic or alternative infrastructure provisioning - consider Terraform
  • Projects need cloud-agnosticism. Porter is tied to AWS.

Getting started

Prerequisites

To use this platform effectively the following is required

  • Comfortable using a command line interface (CLI)
  • Basic understanding of Docker such as what a Dockerfile contains, and the docker build and docker run commands
  • Basic understanding of HTTP, DNS, and SSH

To customize this platform or the infrastructure created, an excellent understanding of CloudFormation templates is required.

Downloading and installing

Download, rename, and chmod the latest release for your platform from the releases page

porter has two runtime dependencies: git and docker.
