【问题描述】：

我已经用 Traefik 摆弄了几个小时，发现它非常有趣。但是，我遇到了一个我自己似乎无法解决的问题。

这是一个非常简单的设置，只是尝试测试 HTTP 到 HTTPS 的重定向和我的 SSL 证书。

我有以下docker-compose.yml

version: '2'

    services:
      traefik:
        image: traefik:v1.3.7-alpine
        ports:
          - "80:80"
          - "443:443"
          - "8080:8080"
        volumes:
          - /var/run/docker.sock:/var/run/docker.sock:z
          - /opt/dockerapp/rocketchat/traefik/traefik.toml:/etc/traefik/traefik.toml:ro,z
          - /opt/dockerapp/rocketchat/traefik/ssl:/etc/traefik/ssl/:ro,z
        command: --logLevel=DEBUG

我的traefik.toml 是

defaultEntryPoints = ["http", "https"]
[entryPoints]
  [entryPoints.http]
  address = ":80"
    [entryPoints.http.redirect]
    entryPoint = "https"
  [entryPoints.https]
  address = ":443"
    [entryPoints.https.tls]
      [[entryPoints.https.tls.certificates]]
        CertFile = "ssl/mycert.pem"
        KeyFile = "ssl/mycert.key"
[docker]
domain = "docker.local"
watch = true

[web]
address = ":8080"

但是，当我尝试运行它时：

docker-compose up

rocketchat_traefik_1 exited with code 1

这似乎表明我的证书有问题。我确信证书没问题，它是我们在 Apache 和 NGINX 上成功使用的通配符证书。

我已经检查了this possible answer，但是证书和私钥都匹配这些参数。

有人能解释一下吗？

谢谢！

尝试为 CertFile 和 KeyFile 设置绝对路径
这解决了我的问题！如果您将其添加为答案，我将很乐意接受它:)
太棒了！很高兴我能帮上忙

【解决方案1】：

看起来 traefik 没有找到您的证书。尝试为 CertFile 和 KeyFile 设置绝对路径，例如：

defaultEntryPoints = ["http", "https"]
[entryPoints]
  [entryPoints.http]
  address = ":80"
    [entryPoints.http.redirect]
    entryPoint = "https"
  [entryPoints.https]
  address = ":443"
    [entryPoints.https.tls]
      [[entryPoints.https.tls.certificates]]
        CertFile = "/etc/traefik/ssl/mycert.pem"
        KeyFile = "/etc/traefik/ssl/mycert.key"
[docker]
domain = "docker.local"
watch = true

[web]
address = ":8080"
