Caddy

Caddy can manage https certificate automatically.

compose.yml

services:
  caddy:
    image: caddy:latest
    container_name: caddy
    restart: unless-stopped
 
    networks:
      - web
    ports:
      - "80:80"
      - "443:443"
 
    volumes:
      - ./Caddyfile:/etc/caddy/Caddyfile
      - ./data:/data
      - ./config:/config
 
networks:
  web:
    external: true

Then run in docker

cd ~/services/caddy
docker compose up -d

Write Caddyfile to map your site. Example like

Caddyfile

auth.xiaobenmao.win {
    reverse_proxy authentik-server-1:9000
}

bits.xiaobenmao.win {
    reverse_proxy bits-wordpress:80
}

wiki.xiaobenmao.win {
    reverse_proxy pkb:8080
}

For any change in Caddyfile during its run, reload it using

cd ~/services/caddy
docker compose exec caddy caddy validate --config /etc/caddy/Caddyfile && \
docker compose exec caddy caddy reload --config /etc/caddy/Caddyfile
