What ports does Traefik expose by default?

Traefik binds to port 80 for HTTP, 443 for HTTPS, and 8080 for the API/dashboard. The ports are configurable via the `entryPoints` flags.

How do I enable Let’s Encrypt in Traefik?

Add the `--certificatesresolvers.le.acme.email=you@example.com` flag and enable `--certificatesresolvers.le.acme.httpchallenge`. Traefik will serve the challenge on port 80 automatically.

Can I use Traefik with Minikube?

Yes, just deploy Traefik as a DaemonSet or Deployment and enable the Kubernetes Ingress provider. The dashboard will still be accessible via the port you expose.

Does Incident.io support GitHub Actions?

Incident.io offers a GitHub Action that creates incidents from workflow failures, syncing the status back to Slack and Jira.

What if I need a load-balanced TCP service?

Traefik’s TCP routers allow you to expose TCP services on any port, similar to HTTP routers but without path-based rules.

Is Traefik safe for production?

Traefik follows best practices for TLS termination, zero-configuration security, and has an active open-source community. Enterprise adds HA and auto-renewals for mission-critical workloads.

Traefik + Incident.io: The DevOps Duo That Cuts Incident Response Time

Table of Contents

TL;DR

Traefik turns Docker or Kubernetes labels into instant routes, so you don’t have to touch config files.
Incident.io stitches Slack, Jira, and GitHub into a single incident response flow that documents everything automatically.
Together they give you a single UI for routes, TLS, and incident status, slashing context switching.

Why this matters

Every time I spin up a new microservice, I used to wrestle with a maze of virtual hosts, port numbers, and an admin console that only told me the status after I broke something. The pain was twofold: first, I had to write and maintain a configuration file for each proxy; second, I spent half my day chasing alerts, hunting for the right team, and then figuring out what happened after the fact. Traefik solves both problems in one go. It reads Docker or Kubernetes labels and builds routes on the fly. It exposes a built-in dashboard that shows every route, middleware, and service in real time. And when you pair it with Incident.io, the moment an alert hits your monitoring stack, a Slack command can declare the incident, a Jira ticket is created, and a status page updates in seconds. The result? Faster resolution, fewer missed alerts, and a single source of truth for both traffic and incidents.

Core concepts

Reverse proxy for microservices Traefik is an open-source reverse proxy and load balancer that sits between your clients and your services. It forwards HTTP, TCP, and UDP traffic to the right backend, adding TLS termination, load balancing, and health checks under the hood. Citation: Traefik — Traefik Proxy Documentation (2024)
Dynamic routing via container labels When you run a container, you can annotate it with traefik.enable=true, traefik.http.routers.myapp.rule=Host(myapp.local), and Traefik will pick it up instantly. No config reload, no extra file. Citation: Traefik — Traefik Docker Provider Documentation (2024)
Automatic TLS with Let’s Encrypt Traefik can request a TLS certificate for each host using the ACME protocol. It stores the keys in acme.json and renews them 30 days before expiry, so you never need to touch cert.pem again. Citation: Traefik — Traefik TLS/ACME Certificate Resolver (2024)
Plugin ecosystem Over 100 community-built plugins exist: cache, geoblocks, IP whitelisting, Cloudflare, captcha, robots.txt, and more. You can add them with a single line in the static config. Citation: Traefik — Traefik Plugin Catalog (2024)
Ingress controller for Kubernetes Traefik implements the Kubernetes Ingress spec. It also supports Nginx-style annotations, making migration a breeze. Citation: Traefik — Traefik Kubernetes Ingress Provider Documentation (2024)
Middleware for security and observability Built-in middlewares include HTTP basic auth, IP allow list, rate limiting, and custom headers. Citation: Traefik — Traefik HTTP Middlewares IPAllowList (2024)
Citation: Traefik — Traefik HTTP Middlewares RateLimit (2024)
Real-time dashboard and API The dashboard, exposed on port 8080, shows all active routers, services, and middlewares. The API can be queried programmatically for integrations. Citation: Traefik — Traefik API & Dashboard Documentation (2024)

How to apply it

Spin up Traefik in Docker Compose

services:
  traefik:
    image: traefik:v3.3
    command:
      - "--api.insecure=true"
      - "--providers.docker=true"
      - "--entrypoints.web.address=:80"
      - "--entrypoints.websecure.address=:443"
      - "--certificatesresolvers.le.acme.httpchallenge.entrypoint=web"
      - "[email protected]"
    ports:
      - "80:80"
      - "443:443"
      - "8080:8080"
    volumes:
      - "/var/run/docker.sock:/var/run/docker.sock:ro"
      - "./acme.json:/acme.json:rw"

Citation: Traefik — Traefik Docker Provider Documentation (2024)

Tag your services

services:
  whoami:
    image: traefik/whoami
    labels:
      - "traefik.enable=true"
      - "traefik.http.routers.whoami.rule=Host(***whoami.local***))"
      - "traefik.http.services.whoami.loadbalancer.server.port=80"

Traefik will pick up whoami.local automatically.

Add middleware

services:
  traefik:
    labels:
      - "traefik.http.middlewares.auth.basicauth.users=admin:$apr1$HfXqB1$5gYQq8p9S8uH0YfF0u1B0"
      - "traefik.http.routers.whoami.middlewares=auth"

Citation: Traefik — Traefik HTTP Middlewares BasicAuth (2024)

Expose metrics Add a Prometheus exporter or use Traefik’s own metrics endpoint on port 9100.
Hook Incident.io
- Install the Incident.io app in your Slack workspace.
- Create a channel, e.g. #incident-response.
- In the channel, run /incident new to declare a fresh incident.
- The Incident.io bot will create a ticket in Jira, post a status page update, and sync a GitHub issue. Citation: Incident.io — Incident.io Slack Integration (2025)
Automate notifications Connect your monitoring system (Datadog, Prometheus Alertmanager, etc.) to Incident.io via the API. When an alert triggers, Incident.io auto-groups it with existing incidents, or creates a new one.
Observe Open http://localhost:8080/dashboard/ to see the live routing map. Open https:///status to see the live status page.

Pitfalls & edge cases

High-availability needs Traefik Enterprise The open-source version can run multiple replicas, but they don’t share state, so routing tables can diverge. Enterprise offers a shared datastore and auto-renewal of certificates. Citation: Traefik — Traefik Enterprise High Availability Documentation (2024)
Auto-renewals fail if DNS is misconfigured ACME challenges rely on either HTTP-01 or DNS-01. If you use DNS-01, the chosen provider must be supported and credentials must be set in the environment. Citation: Traefik — Traefik TLS/ACME Certificate Resolver (2024)
Middleware mis-configuration can block traffic A too-strict IPAllowList or a mis-typed rule can silently drop legitimate requests. Always test in a staging environment.
Plugin compatibility Some community plugins may depend on older Traefik APIs and break after a major upgrade. Keep a changelog and test plugins after each Traefik release.
Not the fastest option Traefik introduces a small additional hop for TCP traffic, which might be noticeable under extremely high load. If latency is mission-critical, benchmark against Nginx or Envoy first.

Open questions we still wrestle with

How do we scale Traefik in a multi-cluster, multi-region setup without Enterprise?
Can we declaratively expose services that don’t use Docker labels (e.g., legacy services in ECS)?
What is the overhead of the Incident.io AI alert grouping in a very noisy environment?

Conclusion

Traefik brings dynamic routing, TLS automation, and a rich plugin ecosystem to your stack with a single image. Pair it with Incident.io and you get an incident response flow that auto-creates tickets, updates status pages, and feeds AI-driven insights back into your monitoring loop. The biggest upside is the reduced context switching: one dashboard shows routes, one platform shows incidents, and your alerts flow straight into a single narrative.

Actionable next steps

Spin up a local Traefik instance with Docker Compose (copy the snippet above).
Add a sample service with a host rule.
Connect the Traefik dashboard to your internal monitoring.
Install the Incident.io Slack app and declare your first incident.
Iterate: add a rate-limit middleware, try the geoblock plugin, and see how the status page updates in real time.

If you’re a DevOps engineer or SRE managing a microservices garden, Traefik + Incident.io is worth the learning curve. If you only need a single static site, a lightweight reverse proxy like Caddy might be simpler.
