突然之间(2018 年 3 月 3 日下午 3 点左右)，我们的 Grafana Docker 实例在 Swisscom Application Cloud (cloudfoundry) 中停止工作。应用云最近有什么变化吗？关于在哪里查看有任何提示吗？

Answer 1

此时我们更新了cloudfoundry/diego以使用garden-runc grootfs并替换garden-sched。
grafana/grafana docker 镜像(latest/5.0.4)包含一个volume指令，该指令在garden-runc v1.12.1(最新)上处理不正确。花园容器中缺少必要的 grafana 文件。请参阅garden-runc issue了解更多详情。

解决方法

可以从 Dockerfile 中删除volume指令。docker build 和 docker Push 到另一个存储库。

从 Dockerfile 中删除此行

VOLUME ["/var/lib/grafana", "/var/log/grafana", "/etc/grafana"]
