我上周在 kubernetes 上部署了哨兵，使用这个掌舵图稳定/哨兵。
Pod 工作正常，但我无法访问该网站，每次我访问端点时它都会崩溃。
我检查了工人，哨兵网和邮政豆荚的日志，看到了这个。
这是网站窗格的日志：

您必须手动迁移架构， 运行以下命令以迁移架构：
kubectl exec -it <your-pod-name> sentry upgrade
求解。 谢谢大家的帮助。问题是我没有足够的 RAM 来运行迁移脚本，所以我将 VPS 升级到 8GB RAM，然后它就可以工作了。
由于迁移脚本有一些内存泄漏，因此 Pod 至少需要 4GB 可用内存才能运行。在 Github 上查看此评论
面临类似的问题。在我们的例子中，我们已经启用了入口(Nginx(。并且此设置与service.type冲突：LoadBalancer，只需将其更改为ClusterIP并再次执行清除设置即可。
TLDR - DB init 在"安装后"事件(所有部署的组件都处于就绪状态(时启动，但在 LoadBallancer、入口和--wait组合的情况下，Web 服务必须分配 IP (https://github.com/helm/helm/blob/master/docs/using_helm.md#helpful-options-for-installupgraderollback(。由于某种原因，它不是真的，Web 服务总是返回false.将服务设置从LoadBalancer更改为ClusterIP后，问题消失了。
