Traefik，多个前端规则到一个 docker 容器

Question

我确实搜索了手册，但确实无法说得很清楚，即使使用关键字谷歌搜索也是如此。

我需要将/_ 代理到API 容器，类似www.mydomain.com/_ => API container 的一些规则

已经有一个指定的域指向这个 API 容器 api.mydomain.com => API container

这是我的docker-compose.yml，我只想添加一条规则，将/_ 也代理到这个容器。

version: '3.3'

services:

  testapi:

    image: git.xxxx.com/api/core/test:latest

    restart: always

    networks:
      - web
      - default

    expose:
      - "80"

    labels:
      - "traefik.enable=true"
      - "traefik.port=80"
      - "traefik.docker.network=web"
      - "traefik.backend=testapi"
      #this domain is used for app
      - "traefik.frontend.rule=Host:api.test.mydomain.com"
      #this is used for website.All I want is prxy "https://www.test.mydomain.com/_/" to this container
      - "traefik.frontend.rule1=Host:www.test.mydomain.com;PathPrefixStrp:/_"

Answer 1

您可以使用分段标签：

version: '3.3'

services:
 testapi:
   image: git.xxxx.com/api/core/test:latest
   restart: always
   networks:
     - web
     - default
   expose:
     - "80"
   labels:
     - "traefik.enable=true"
     - "traefik.port=80"
     - "traefik.docker.network=web"
     #this domain is used for app
     - "traefik.foo.frontend.rule=Host:api.test.mydomain.com"
     - "traefik.bar.frontend.rule=Host:www.test.mydomain.com,m.test.mydomain.com;PathPrefixStrp:/_"
