Traefik Ingress（Kubernetes）没有收到letsencrypt证书

Question

我用let'sencrypt ACME配置了Traefik（掌舵图），但我没有收到任何证书。 Traefik Ingress在80和443端口上网。

traifik.toml

logLevel = "INFO"
InsecureSkipVerify = true
defaultEntryPoints = ["http","https"]
[entryPoints]
  [entryPoints.http]
  address = ":80"
  compress = true
  [entryPoints.https]
  address = ":443"
  compress = true
    [entryPoints.https.tls]
      [[entryPoints.https.tls.certificates]]
      CertFile = "/ssl/tls.crt"
      KeyFile = "/ssl/tls.key"
[kubernetes]
[acme]
email = "[email protected]"
storage = "/acme/acme.json"
entryPoint = "https"
onHostRule = true
caServer = "https://acme-staging-v02.api.letsencrypt.org/directory"
acmeLogging = true
  [acme.httpChallenge]
  entryPoint = "http"
[web]
address = ":8080"

与Traefik一起进入IngressClass

                "servicePort": 443
              }
            }
          ]
        }
      },
      {
        "host": "www.domain.com",
        "http": {
          "paths": [
            {
              "backend": {
                "serviceName": "www-domain",
                "servicePort": 443
              }
            }
          ]
        }
      }
    ]
  },
  "status": {
    "loadBalancer": {}
  }
}

我试过使用http-01和tls-sni-01挑战。 dns-01是没有选项，因为我的DNS提供商没有API。

Answer 1

你如何将letsencrypt配置注入你的traefik Ingress服务/守护进程？

Traefik没有正式对Kubernetes Ingress文档进行过密切关注。但这是一个good guide。寻找“外部Traefik入口控制器”，您需要一个kv后端来存储您的证书。

您也可以尝试与Traefik合作的cert-manager。

Answer 2

建议不要在Kubernetes上使用内置的ACME对Traefik的支持，因为设置故障转移/冗余变得困难。如Rico所述，Cert-manager是一个更好的解决方案，也是Traefik团队目前推荐的:)
