🔍 Service Discovery & Dynamic Configuration with TuskLang & Go

Introduction

Service discovery and dynamic config are the backbone of resilient, cloud-native systems. TuskLang and Go let you wire up Consul, etcd, or Kubernetes, reload configs live, and roll out features with zero downtime.

Key Features

- Consul/etcd/Kubernetes integration - Dynamic config reloading - Feature flags and environment switching - Zero-downtime deployments

Example: Service Discovery Config

[discovery]
backend: consul
uri: @env("CONSUL_URI")
register: @go("discovery.Register")
lookup: @go("discovery.Lookup")

Go: Consul Integration Example

package discovery
import (
  "github.com/hashicorp/consul/api"
)
func Register(service string) error {
  // Register with Consul
}
func Lookup(service string) (string, error) {
  // Lookup service address
}

Dynamic Config Reloading

- Use TuskLang’s @file.read and @env for live reloads - Go watches config files or Consul/etcd keys

Feature Flags & Env Switching

[feature_flags]
new_ui: @env("ENABLE_NEW_UI", false)

Zero-Downtime Deployments

- Use Go’s goroutines for hot reloads - TuskLang config: reload: @go("discovery.Reload")

Best Practices

- Store all service endpoints in TuskLang - Use @env for environment-specific config - Monitor with @metrics

Troubleshooting

- Check Go logs for discovery failures - Use TuskLang’s @cache for fallback endpoints

Conclusion

TuskLang + Go = service discovery that’s dynamic, resilient, and cloud-native.
