Create acme.json

sudo touch /etc/docker/volumes/traefik/acme.json
sudo chmod 600 /etc/docker/volumes/traefik/acme.json

Create network

sudo docker network create traefik

Start traefik

sudo docker-compose up -d

You can no access the Traefik dashboard at https://traefik.$example.com$ with the credentials you set in traefik_dynamic.yml.

Add Labels to wg-easy

To add labels to your wg-easy service, you can add the following to your docker-compose.yml file:

File: /etc/docker/containers/wg-easy/docker-compose.yml

services:
  wg-easy:
    ...
    container_name: wg-easy
    networks:
      ...
      traefik: {}
    labels:
      - "traefik.enable=true"
      - "traefik.http.routers.wg-easy.rule=Host(`wg-easy.$example.com$`)"
      - "traefik.http.routers.wg-easy.entrypoints=websecure"
      - "traefik.http.routers.wg-easy.service=wg-easy"
      - "traefik.http.services.wg-easy.loadbalancer.server.port=51821"
    ...

networks:
  ...
  traefik:
    external: true

Restart wg-easy

cd /etc/docker/containers/wg-easy
sudo docker-compose up -d

You can now access wg-easy at https://wg-easy.$example.com$ and start the setup.
