如何解决“无法在键输入中找到任何PEM数据”错误？

Question

我正在使用Docker Swarm为Traefik设置HTTPS提供的证书，并且不会加载失败的failed to find any PEM data in key input

我尝试使用相对路径和绝对路径进行设置（请参阅https://github.com/containous/traefik/issues/2001），但似乎无法解决问题。

我使用的证书是自签名的，但是可以与Nginx完美结合。

Traefik配置在撰写中

Answer 1

回答我自己的问题：这就是我在上面的Compose文件中传递命令行参数的方式。

Traefik这样不接受证书：

      - "--defaultentrypoints=http,https"
      - "--docker"
      - "--docker.swarmMode"
      - "--docker.exposedByDefault=false"
      - "--docker.domain=sdb.it"
      - "--docker.watch"
      - "--entryPoints='Name:http Address::80 Redirect.EntryPoint:https'"
      - "--entryPoints='Name:https Address::443 TLS:/etc/ssl/certs/sonarqube.crt,/etc/ssl/certs/sonarqube.key'"
      - "--loglevel=DEBUG"

但是，如果您删除了我错误地放在entryPoints参数中的引号，它会做到：

    command:
      - --defaultentrypoints=http,https
      - --docker
      - --docker.swarmMode
      - --docker.exposedByDefault=false
      - --docker.domain=sdb.it
      - --docker.watch
      - --entryPoints=Name:http Address::80 Redirect.EntryPoint:https
      - --entryPoints=Name:https Address::443 TLS:/etc/ssl/certs/sonarqube.crt,/etc/ssl/certs/sonarqube.key
