HTTP Server Example

This GoFr example demonstrates a simple HTTP server which supports Redis and MySQL as datasources.

To run the example, follow the steps below:

1. Run with Docker Compose (recommended)

From the project root (/gofr):

docker compose -f examples/http-server/docker/docker-compose.yml up -d

• Explanation:

  • -f examples/http-server/docker/docker-compose.yml → path to the docker-compose file
  • up -d → builds (if needed) and runs services in detached mode

---

2. Build & Run Manually (without docker-compose)

Build the Docker image

From the project root (/gofr):

docker build -f examples/http-server/Dockerfile -t http-server:latest .

• Explanation:

  • -f examples/http-server/Dockerfile → path to the Dockerfile
  • -t http-server:latest → tag for the Docker image
  • . → build context (project root; needed for go.mod and go.sum)

Run the Docker container

docker run -p 9000:9000 --name http-server http-server:latest

• Explanation:

  • -p 9000:9000 → maps container port 9000 to host port 9000
  • --name http-server → optional, gives your container a name

• Use Compose when you want the whole stack (app + Redis + MySQL + Grafana + Prometheus).

• Use Docker build/run when you just want to run the app container alone.

To test the example, follow these steps:

1. Open your browser and navigate to http://localhost:9000/hello.
2. To view the GoFr trace, open https://tracer.gofr.dev and paste the traceid.
3. To access the Grafana Dashboard, open http://localhost:3000. The dashboard UI will be displayed. Use the default admin credentials to log in:
   • Username: admin
   • Password: password
