Omada Controller behind traefik

Few things to consider and requirements,

  • traefik in the Docker
  • Valid Domain required
  • Cloudflare is Authoritative DNS server

Above things can be manipulated based on the requirements

Install docker​

Install docker with the following,

curl -sSL https://get.docker.com | sh -

Post docker installation documentation can be found here.

traefik​

Before deploying traefik, we need few things. First create a directory traefik in home directory with mkdir trafik. Everything will be inside this directory.

traefik config​

Create traefik.yaml and add following content modify the given details

api:
  dashboard: true
  debug: true
entryPoints:
  http:
    address: ":80"
    http:
      redirections:
        entryPoint:
          to: https
          scheme: https
  https:
    address: ":443"
  dnsovertls:
    address: ":853"
serversTransport:
  insecureSkipVerify: true
providers:
  docker:
    endpoint: "unix:///var/run/docker.sock"
    exposedByDefault: false
  file:
    directory: /config
    watch: true
certificatesResolvers:
  cloudflare:
    acme:
      email: [email protected]
      storage: acme.json
      dnsChallenge:
        provider: cloudflare
        resolvers:
          - "1.1.1.1:53"
          - "1.0.0.1:53"

What's going on inside

  • Dashboard is exposed
  • Debugging is enabled for troubleshooting.
  • Here 2 entry points are defined, http at port 80 and https at port 443.
  • http is redirecting to entry point https.
  • Using docker provider at /var/run/docker.sock.
  • Using file config for defining routes, services & entrypoints and stored in /config directory.
  • Using Cloudflare for certificate resolution. Update with actual email.

network​

Create a network for traefik usage.

docker network create proxy

docker compose​

traefik deployment with compose as following

---

services:
  traefik:
    image: traefik:latest
    container_name: traefik
    restart: always
    security_opt:
      - no-new-privileges:true
    networks:
      - proxy
    ports:
      - 80:80
      - 443:443
    dns:
      - 1.1.1.1
      - 1.0.0.1
    environment:
      - CF_API_EMAIL=${CF_API_EMAIL}
      # - CF_API_KEY=${CF_API_KEY}
      - CF_API_TOKEN=${CF_API_TOKEN}
    volumes:
      - /etc/localtime:/etc/localtime:ro
      - /var/run/docker.sock:/var/run/docker.sock:ro
      - ./traefik.yml:/traefik.yml:ro
      - ./data/acme.json:/acme.json
      - ./data/config:/config:ro
    labels:
      - "traefik.enable=true"
      - "traefik.http.routers.traefik.entrypoints=http"
      - "traefik.http.routers.traefik.rule=Host(`traefik.example.com`)"
      - "traefik.http.middlewares.traefik-auth.basicauth.users=<user:password>"
      - "traefik.http.middlewares.traefik-https-redirect.redirectscheme.scheme=https"
      - "traefik.http.middlewares.sslheader.headers.customrequestheaders.X-Forwarded-Proto=https"

      - "traefik.http.routers.traefik-secure.rule=Host(`traefik.example.com`)"
      - "traefik.http.routers.traefik-secure.middlewares=traefik-auth"
      - "traefik.http.routers.traefik-secure.tls=true"
      - "traefik.http.routers.traefik-secure.tls.certresolver=cloudflare"
      - "traefik.http.routers.traefik-secure.tls.domains[0].main=example.com"
      - "traefik.http.routers.traefik-secure.tls.domains[0].sans=*.example.com"
      - "traefik.http.routers.traefik-secure.service=api@internal"

networks:
  proxy:
    external: true

Few things before deploying this.

Cloudflare Credentials​

Generate Cloudflare token with Zone and DNS scopes or Use legacy API key with Email. Save them in .env file.

CF_API_EMAIL=
CF_API_KEY=
CF_API_TOKEN=

Config​

Create a directory data with

mkdir data

Create a acme.json to store cert data

touch data/acme.json
warning

Do not edit acme.json file.

Create config directory and omada.yaml to store file config for defining routes and etc

mkdir data/config
touch data/config/omada.yaml

Basic auth for traefik dashboard​

Generate username/password pair with following

echo $(htpasswd -nB user) | sed -e s/\\$/\\$\\$/g

Update the labels in compose file

labels:
  - "traefik.http.middlewares.traefik-auth.basicauth.users=<user:password>"

Deploy traefik​

To deploy traefik

docker compose up -d

This will deploy the traefik container and completes acme challenge and generates certificate from Let's Encrypt. This config can be found on GitHub.

note

If anything goes wrong, check container logs.

Omada routes​

Add the following content to data/config/omada.yaml

---
http:
  routers:
    oc-router:
      entryPoints:
        - "https"
      service: oc-service
      rule: "Host(`omada.example.com`)" # change it to actual address
      tls: {}
      middlewares:
        - default-headers
        - https-redirect

  services:
    oc-service:
      loadBalancer:
        servers:
          - url: https://10.20.20.119:8043 # change it to actual ip of the controller

  middlewares:
    https-redirect:
      redirectScheme:
        scheme: https
        permanent: true

    default-headers:
      headers:
        frameDeny: true
        sslRedirect: true
        browserXssFilter: true
        contentTypeNosniff: true
        forceSTSHeader: true
        stsIncludeSubdomains: true
        stsPreload: true
        stsSeconds: 15552000
        customFrameOptionsValue: SAMEORIGIN
        customRequestHeaders:
          X-Forwarded-Proto: https

    default-whitelist:
      IPAllowList:
        sourceRange:
        - "10.0.0.0/8"
        - "192.168.0.0/16"
        - "172.16.0.0/12"
        - "100.64.0.0/10"

    secured:
      chain:
        middlewares:
        - default-headers

In traefik.yaml, file config is set as following

providers:
  file:
    directory: /config
    watch: true # updates the config with out restart

Config will be auto updates by traefik and no need to restart the container. Omada controller is available at omada.example.com.
