我们已经 traefik 一年多了，它一直很棒。我们目前在 1.6.6 上，一切正常，一旦我们尝试升级到 1.7，我们所有的端点都会得到 502。知道为什么会发生这种情况吗？

我们正在尝试升级，因为 NS1 是作为 DNS 提供程序引入的，而且 HTTP 挑战似乎不再起作用。

这是我们当前的设置：

apiVersion: v1
data:
  traefik.toml: |
    # traefik.toml
    defaultEntryPoints = ["http", "https"]
    [web]
    address = ":8080"

    [entryPoints]
      [entryPoints.http]
        address = ":80"
        [entryPoints.http.redirect]
          entryPoint = "https"

      [entryPoints.https]
      address = ":443"
       [entryPoints.https.redirect]
         [entryPoints.https.tls]

    [kubernetes]
    [acme]
    email = "devops@something.com"
    storage = "/acme/acme.json"
    entryPoint = "https"
    acmeLogging = true
    caServer = "https://acme-v02.api.letsencrypt.org/directory"
    [[acme.domains]]
      main = "something.com"
    [[acme.domains]]
      main = "something.com"
    [acme.httpChallenge]
      entryPoint = "http"
    [retry]
    attempts = 5
    [accessLog]
    [traefikLog]
    filePath = "/acme/traefik.log"

        name: traefik
        ports:
        - containerPort: 80
          protocol: TCP
        - containerPort: 443
          protocol: TCP
        - containerPort: 8080
          protocol: TCP
        securityContext:
          privileged: true
        readinessProbe:
          tcpSocket:
            port: 80
          initialDelaySeconds: 20
        volumeMounts:
        - mountPath: /config
          name: config
        - mountPath: /acme
          name: acme
      volumes:
      - configMap:
          name: traefik
        name: config
      - hostPath:
          path: /etc/traefik
        name: acme

似乎我们得到了：

似乎 traefik 增加了它们在字节之间的时间，并且我们的内部缓存因此而超时。通过增加超时来修复。
