  • My homelab stack in 2026: what runs, why, and how it all connects
    Everything HTTP goes through Traefik. It's the reverse proxy in front of every Docker-hosted service, and the main reason I chose it over Nginx or Caddy is Docker-native autodiscovery. When I bring up a new container with the right labels, it appears behind a subdomain with automatic TLS, no config file reload required. That removes enough friction that I'm less tempted to leave things running unproxied on bare... - Source: dev.to / 3 months ago
  • Traefik vs HAProxy: Reverse Proxy Showdown
    Traefik (v3.6) is a cloud-native edge router that watches Docker, Kubernetes, and other providers for service changes. When you deploy a new container with the right labels, Traefik automatically creates a route and provisions an SSL certificate. Configuration is split between a static config file (entry points, providers) and dynamic config (Docker labels on each service). - Source: dev.to / 6 months ago
  • Traefik vs Caddy: Which Reverse Proxy?
    Traefik (v3.6) is a cloud-native edge router written in Go. It watches Docker, Kubernetes, and other providers for service changes and automatically creates routes based on labels. Configuration is split between a static config file and dynamic config via labels or files.

  • Controlling Kubernetes Network Traffic – Part 1
    Traefik is a modern, cloud-native reverse proxy and load balancer that also serves as a Kubernetes Ingress Controller. It acts as an in-cluster application that integrates with the Kubernetes API to automatically detect Ingress resources and dynamically configure itself to route incoming HTTP/HTTPS traffic to the appropriate backend services within the cluster. - Source: dev.to / 10 months ago
  • Why We Moved API Authentication from the Gateway to Our Microservices
    Then we started looking into Kong alternatives, and found multiple options: Envoy, Traefik, etc... But migrating from Kong plugin into those would be a bit painful and wasn't guaranteed to be smooth as we use a single domain and it can point to only one of those Ingress controllers. - Source: dev.to / 11 months ago
