CloudFormation Templates: ECS Cluster and Service, Legacy VPC Wrapper, and Automated Tests

In the latest batch of free Wittig CloudFormation templates, easily work with containerized projects with ECS, wrap a VPC into a needed format, and a new test suite.

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.

Architecture

Install the free template.

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.

Architecture

Install the free template.

Using a Dedicated Load Balancer for the Service

This template describes a fault tolerant and scalable ECS service that uses a dedicated load balancer for the service.

Architecture

Install the free template.

VPC Legacy Wrapper

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

Install the free template.

Automated Tests

The goal of the tests is to ensure that our templates are always working. The tests 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.
