docker - 将 Traefik 前端重定向替换与 PathPrefixStrip 相结合

Question

我在 traefik.frontend.redirect 和 PathPrefixStrip 之间遇到一些冲突。下面的 docker-compose.yml 文件始终将 www.mysite.nl/adminer 路由到 WordPress 容器。如果我省略重定向规则，它会正常工作，并且我会被路由到管理员实例。我怎样才能使这些规则一起发挥作用？

深入了解docker-comose.yml:

version: '3'
services:
  wordpress:
    image: wordpress:latest 
    restart: $RESTART
    container_name: ${COMPOSE_PROJECT_NAME}_wp
    depends_on:
      - mysql
    networks:
      - web
    labels:
      - 'traefik.backend=$COMPOSE_PROJECT_NAME'
      - 'traefik.entrypoint=https'
      - 'traefik.enable=true'
      - 'traefik.frontend.rule=Host:mysite.nl, www.mysite.nl, cdn.mysite.net'
       # omitting these rules make the adminer instance reachable
      - 'traefik.frontend.redirect.regex=^https?://mysite.nl/(.*)'
      - 'traefik.frontend.redirect.replacement=https://www.mysite.nl/$${1}'
  mysql:
    image: mysql:latest
    restart: $RESTART
    container_name: ${COMPOSE_PROJECT_NAME}_db
    networks:
      - web
  adminer:
    image: adminer:4.6.2
    restart: $RESTART
    container_name: ${COMPOSE_PROJECT_NAME}
    depends_on:
      - mysql
    networks:
      - web
    labels:
      - 'traefik.backend=${COMPOSE_PROJECT_NAME}_adminer'
      - 'traefik.entrypoint=https'
      - 'traefik.enable=true'
      - 'traefik.frontend.rule=Host:www.mysite.nl;PathPrefixStrip:/adminer'

networks:
  web:
    external:
      name: traefik_${COMPOSE_PROJECT_NAME}_web

Answer 1

您遇到的问题是由于规则重叠造成的。

请求www.mysite.nl/adminer

同时匹配:traefik.frontend.rule=主机:mysite.nl、www.mysite.nl、cdn.mysite.net和 traefik.frontend.rule=Host:www.mysite.nl;PathPrefixStrip:/adminer

因此 Traefik 不知道将请求路由到哪个。

使用traefik.frontend.priority标签设置匹配顺序(来自https://docs.traefik.io/configuration/backends/docker/#on-containers)
