Consul service

This repo contains a simple Go backend comprised of:

• 1 frontend facing service web
• 1 backend service backend

web uses Consul for service discovery to connect to backend instances and issue requests against it. Several Consul checks are also registered with Consul agent:

• TTL based checks which are basically heartbeats issued from services towards Consul agent
• HTTP healthecks which are basically HTTP requests issues from the Consul agent against defined services' healthcheck endpoints

To observe the state of the system please open http://localhost:8500/ in your browser.

How to run

docker-compose up -d

Optionally one can dynamically adjust number of backend services to observe how they dynamically register and deregister with Consul agent.

docker-compose up --no-recreate -d --scale backend=5

How to teardown

docker-compose down --remove-orphans
