我将如何配置一个需要循环变量的字典?

How would I configure a dictionary which requires variables in a loop?

我有一个 docker_container,我想为多个用户部署它,并在用户之后命名 traefik 路由。但我对如何实现这一目标感到困惑。

这是我的资料:

- name: Run syncthing
  docker_container:
    name: "{{ item.name }}-syncthing"
    image: "lscr.io/linuxserver/syncthing"
    state: started
    restart_policy: "always"
    env:
      PUID: "1000"
      PGID: "1000"
    volumes:
      - "{{ item.data_dir }}:/data"
... other volumes
    labels:
      traefik.enable: true
      "traefik.http.routers.{{ item.name }}-syncthing.entrypoints": websecure
      "traefik.http.routers.{{ item.name }}-syncthing.rule": Host(`{{ item.name }}.{{ fqdn_real }}`)
      "traefik.http.routers.{{ item.name }}-syncthing.tls": true
      "traefik.http.routers.{{ item.name }}-syncthing.tls.certresolver": le 
      "traefik.http.routers.{{ item.name }}-syncthing.service": "{{ item.name }}-syncthing"
      "traefik.http.routers.{{ item.name }}-syncthing.middlewares": "{{ item.name }}-basicauth"
      "traefik.http.services.{{ item.name }}-syncthing.loadbalancer.server.port": 8080
      "traefik.http.middlewares.{{ item.name }}-syncthing-basicauth.basicauth.users": "{{ item.auth }}"
  with_items: "{{ syncthing_containers_info }}"

还有一个 syncthing_config_info 这样的:

syncthing_containers_info:
  - { name: "c1", data_dir: "/mnt/data/c1/data", auth: "..." }
  - { name: "c2", data_dir: "/mnt/data/c2/data", auth: "..." }
  - { name: "c3", data_dir: "/mnt/data/c3/data", auth: "..." }

该代码段不起作用,因为 ansible 不喜欢语法所以我尝试 thiswith_nested 但我在尝试时遇到了类似的嵌套循环问题set_fact 与示例中一样,因为标签集取决于 syncthing_containers_info。我有更好的方法吗?

听起来你需要 labels: 是一个实际的 dict 因为 yaml 键不受 jinja2 插值的影响

    labels: >-
      {%- set key_prefix = "traefik.http.routers." ~ item.name ~"-syncthing" -%}
      {{ {
      "traefik.enable": True,
      key_prefix ~ ".entrypoints": "websecure",
      key_prefix ~ ".rule": "Host(`" ~ item.name ~"."~ fqdn_real ~"`)",
      key_prefix ~ ".tls": True,
      key_prefix ~ ".tls.certresolver": "le",
      key_prefix ~ ".service": item.name ~ "-syncthing",
      key_prefix ~ ".middlewares": item.name ~ "-basicauth",
      "traefik.http.services." ~ item.name ~ "-syncthing.loadbalancer.server.port": 8080,
      "traefik.http.middlewares." ~ item.name ~"-syncthing-basicauth.basicauth.users": item.auth,
      } }}

(请注意,我没有对此进行测试,只是从你的问题中观察了一下,但这是一般的想法)
