Traefik 2.2 无法获取letsencrypt证书

Question

我有一个带有 MongoDB 容器、python 后端服务和搬运工的应用程序。 Traefik 用于路由到 portainer 和后端（一个 API 端点）。路由工作完美。但是，我想使用 SSL，但 Traefik 2.2 没有获取 LetsEncrypt 证书。

Dockerfile（我在打包一个容器，做一个acme.json的chmod）

FROM traefik:v2.2

COPY traefik /etc/traefik

RUN chmod 600 /etc/traefik/acme.json

docker-compose.yml:

version: "3.3"

services:

  backend:
    image: registry.gitlab.com/uuuu/backend:latest

我在日志中没有看到任何错误。但是我在浏览器中得到了这个：

ea351828037eb97754d6ed00d36a2108.e645b5289e7388055e4ecd78af554f8.traefik.default.
 
Fehlercode: MOZILLA_PKIX_ERROR_SELF_SIGNED_CERT

我有什么遗漏吗？

Answer 1

我自己想出来的。我必须将它添加到每个服务的 docker-compose 文件中：

traefik.http.routers.fiverr-autocompletion.tls.domains[0].main=app.mydomain.com

那么正确的 docker-compose 如下所示：

version: "3.3"

services:

  backend:
    image: registry.gitlab.com/uuuu/backend:latest
    container_name: backend
    ports:
      - 5000
    environment:

      - CONNECTOR_MAX_WORKERS=$CONNECTOR_MAX_WORKERS
      - LOGLEVEL=$LOGLEVEL
      - MONGODB_URI=mongodb://scraper-db/blubb
    depends_on: 
      - db
    labels:
      - 'traefik.enable=true'
      - 'traefik.http.routers.backend.rule=Host(`app.mydomain.com`)'
      - 'traefik.http.routers.backend.rule=PathPrefix(`/api/bla/`)'
      - 'traefik.http.routers.backend.tls.domains[0].main=app.mydomain.com'
