docker-traefik's Introduction

🐋 Docker 🐁 Traefik 🦄 .Localhost

Use Traefik to proxy Docker containers for *.localhost development. Assuming *.localhost domains resolve to the loopback interface.

Now updated to provided HTTPS for a custom domain.

Usage

Create a bridge network named traefik:

docker network create -d bridge traefik

Create an .env file (chmod 600):

TRFK_HOST_IP=127.0.0.1
TRFK_HTTP_PORT=80
TRFK_HTTPS_PORT=443
TRFK_ACME_DOMAIN=example.dev
[email protected]
TRFK_ACME_PROVIDER=cloudflare
TRFK_ACME_RESOLVER="1.1.1.1:53"
CF_DNS_API_TOKEN="see: https://go-acme.github.io/lego/dns/cloudflare/"

Start the Traefik container (this repo):

docker-compose up -d

Discovery

Traefik will automatically discover containers in the traefik network that use labels. See docker-compose.yml for the full example service.

Insecure .localhost domain:

labels:
  - "traefik.enable=true"
  - "traefik.http.routers.whoami.rule=Host(`whoami.localhost`)"
  - "traefik.http.services.whoami.loadbalancer.server.port=80"

Secure domain:

labels:
  - "traefik.enable=true"
  - "traefik.http.routers.whoami.entrypoints=websecure"
  - "traefik.http.routers.whoami.rule=Host(`whoami.${TRFK_ACME_DOMAIN}`)"
  - "traefik.http.services.whoami.loadbalancer.server.port=80"

Or via the dynamic.yml config file:

http:
  routers:
    whoami:
      entryPoints: ['websecure']
      rule: "Host(`whoami.{{ env "TRFK_ACME_DOMAIN" }}`)"
      service: whoami
  services:
    whoami:
      loadBalancer:
        servers:
          - url: "http://whoami"
