Overview

This is a reference design and implementation of an environment template to provision self service developer environments running on Amazon ECS. This reference design is based on Rafay's Environment Manager.

---

Source Code for Template

The Terraform source code and related assets are available in a public Git repo as shown below

---

Design & Architecture

This design assumes an ECS cluster will be created and assigned on-demand to the developer for their applications.

---

Initial Setup

The platform team is expected to setup the Environment Manager templates in a Rafay project that will then be used by developers for self service provisioning of ECS clusters.

Request for Environment

When a developer requests a cluster via self service, a series of automated workflows need to be performed to fulfil this request. The sequence diagram below describes the high level steps.

Important

Although the recommended workflow assumes and recommends using an Integration with an Identity Provider (IdP) to provide a Single Sign On (SSO) experience, organizations can also use locally managed users.
