docker + traefik vhost to container proxy ( single machine )

lets create tnet first with:

docker network create tnet

then create traefik folder and put following contents to docker-compose.yml

version: "3.9"
services:
  traefik:
    image: traefik
    restart: always
    command:
      - "--log.level=DEBUG"
      - '--providers.docker.exposedByDefault=false'
      - "--entrypoints.web.address=:80"
      - "--entrypoints.websecure.address=:443"
      - "--serverstransport.insecureskipverify=true"
      - "--certificatesresolvers.le.acme.storage=/acme.json"
      - "--certificatesresolvers.le.acme.tlschallenge=true"
      - "--certificatesresolvers.le.acme.httpchallenge.entrypoint=web"
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
    labels:
      - traefik.enable=true
    ports:
      - "80:80"
      - "443:443"
    networks:
      - lanuske


networks:
  tnet:
    name: tnet
    external: true

enter traefik directory and run docker-compose up -d

and config for each "microservice"

version: "3.9" 
  # other containres
  # db:
  # image: mariadb:latest

  # this with traefik tags, will be exposed to the internet with a subdomain name
  nginx:
    image: nginx
    restart: always
    labels:
      - traefik.enable=true
