Demo code and microservices for the HashiCorp Consul 101 course.
Email training@hashicorp.com or see https://www.hashicorp.com/training for details.
To run both microservices with Docker Compose (but without Consul), run docker compose up.
$ cd demo-consul-101
$ docker-compose up
You can view the operational application dashboard at http://localhost:8080
A subsequent evolution of the application would involve registering each service with Consul and using Consul DNS to configure services to discover each other.
More documentation is coming. In the meantime, you can start a local demo with:
consul agent -dev -config-dir="./demo-config-localhost" -node=laptop
Then start instances of dashboard-service and counting-service
cd services/dashboard-service
PORT=9002 go run main.go
cd services/counting-service
PORT=9003 go run main.go
cd services/counting-service
PORT=9004 go run main.go
consul connect proxy -sidecar-for counting-1
consul connect proxy -sidecar-for counting-2
consul connect proxy -sidecar-for dashboard
