Consul

A service networking platform by HashiCorp providing service discovery, health checking, distributed KV store, and multi-datacenter federation. Ships as a single binary with embedded Raft storage.

What You Can Do After Deployment

1. Visit your domain — the Consul web UI loads immediately, no login required in dev mode
2. Browse services — view all registered services and their health status
3. Explore nodes — inspect node metadata, health checks, and coordinates
4. Use the KV store — create, read, update, and delete key-value pairs directly from the UI
5. Register services — use the HTTP API to register services: curl -X PUT -d '{"Name":"web","Port":8080}' https://YOUR_DOMAIN/v1/agent/service/register
6. Query DNS — Consul provides DNS interface for service discovery
7. Health checking — define HTTP, TCP, script, or TTL-based health checks
