Service Discovery in Container Orchestration Frameworks on AWS

Service Discovery in Containers on AWS

Table of Contents

• Build services
• Setup cluster and deploy application
• Access application

This repo has a simple example that shows service discovery for different container orchestration frameworks.

The sample application uses three services:

1. webapp: Web application microservice uses greeter and name microservice to generate a greeting for a person.

2. greeter: A microservice returns a greeting based upon greet name/value keypair in the URL.

3. name: A microservice that returns person’s name based upon id name/value keypair in the URL.

These services are built as Docker image and deployed in Docker, Amazon ECS, Kubernetes and DC/OS.

All services are built as Node.js application. webapp service need to be configured using the following parameters:

1. NAME_SERVICE_HOST

2. NAME_SERVICE_PORT

3. NAME_SERVICE_PATH

4. GREETER_SERVICE_HOST

5. GREETER_SERVICE_PORT

6. GREETER_SERVICE_PATH

Build services

Build Docker images for different services:

docker-compose build

Setup cluster and deploy application

1. Docker

2. Amazon ECS

3. Kubernetes

4. DC/OS

Access application

Access the following URLs using curl or in browser:

http://<host>:<port>
http://<host>:<port>0?greet=ho
http://<host>:<port>?id=1
http://<host>:<port>?greet=ho&id=1

Framework	<host>	<port>
Docker	Master node public IP	80
ECS	External ALB Address	80
Kubernetes	Load Balancer Ingress	80
DC/OS	Public Slave Address	80

container-service-discovery's Issues

Running on my own kubenetes cluster.

Hi Arun,

just wondering if you had time to expand this to running on your own K8s cluster. I'm not using any cloud, I have k8s installed on several VM's on my network and am really struggling to work out how this all hangs together when your not using things like AWS load balancers etc.
