New CloudFormation Templates - ECS Cluster & Service, legacy VPC wrapper, automated tests

Michael Wittig – 28 Feb 2017

We released v3 of our free and open source CloudFormation templates. This release brings:

ECS

EC2 Container Service (ECS) is a highly scalable, fast, container management service that makes it easy to run, stop, and manage Docker containers on a cluster of Amazon EC2 instances. To run an application on ECS you need the following components:

We provide you templates for the ECS cluster and the service. You need to publish the Docker image.

ECS cluster

This template describes a fault tolerant and scalable ECS cluster on AWS. The cluster scales the underlying EC2 instances based on memory and CPU reservation. In case of a scale down, the instance drains all containers before it is terminated.

ECS service

This template describes a fault tolerant and scalable ECS service on AWS. The service scales based on CPU utilization.

The image needs to expose port 80 or the AWS::ECS::TaskDefinition needs to be adjusted!

We provide two service templates:

  • service-cluster-alb.yaml uses the cluster’s load balancer and path based routing. If you want to run multiple services on the same cluster they all will use the same domain name but start with different paths (e.g. https://yourdomain.com/service1/ and https://yourdomain.com/service2/).
  • service-dedicated-alb.yaml includes a dedicated load balancer (ALB). You can then use a separate domain name for each service.

Using the cluster’s load balancer and path based routing

This template describes a fault tolerant and scalable ECS service that uses the cluster’s load balancer and path based routing.

VPC legacy wrapper

If you have an existing VPC you can wrap it into our required form using a legacy VPC wrapper.

Automated tests

The goal of the tests is to ensure that our templates are always working. The test are implemented in Java 8 and run in JUnit 4.

If you run this tests, many AWS CloudFormation tests are created and charges will apply!

widdix GmbH sponsors the test runs on every push and once per week to ensure that everything is working as expected.

I'm an independent consultant, technical writer, and programming founder. All these activities have to do with AWS. I'm writing this blog and all other projects together with my brother Andreas.

In 2009, we joined the same company as software developers. Three years later, we were looking for a way to deploy our software—an online banking platform—in an agile way. We got excited about the possibilities in the cloud and the DevOps movement. It’s no wonder we ended up migrating the whole infrastructure of Tullius Walden Bank to AWS. This was a first in the finance industry, at least in Germany! Since 2015, we have accelerated the cloud journeys of startups, mid-sized companies, and enterprises. We have penned books like Amazon Web Services in Action and Rapid Docker on AWS, we regularly update our blog, and we are contributing to the Open Source community. Besides running a 2-headed consultancy, we are entrepreneurs building Software-as-a-Service products.

We are available for projects.
