使用 Ansible 和 Helm 在 AKS 集群上部署 Loki 导致“等待条件超时”错误

Question

我正在尝试使用 Ansible 和 Helm 在我的 AKS 集群上部署 Loki。我集群的版本目前是1.24.10。我正在使用以下配置：

Loki图表版本：5.0.0 球童版本：2.8.0 当我使用 Grafana Helm 图表 (https://grafana.github.io/helm-charts) 部署 Loki 时，我的管道中出现以下错误：

Failure when executing Helm command. Exited 1.
stdout: Release "loki" does not exist. Installing it now.
stderr: Error: timed out waiting for the condition
stderr: |-
Error: timed out waiting for the condition

检查我的 Loki pod（loki-write 和 loki-read）在CrashLoopBackOff 中的日志后，我发现了以下错误：

level=error ts=2023-04-19T15:46:46.224948881Z caller=log.go:171 msg="error running loki" err="mkdir /data: read-only file system\nerror creating index client\ngithub.com/grafana/loki/pkg/storage.(*store).storeForPeriod\n\t/src/loki/pkg/storage/store.go:270\ngithub.com/grafana/loki/pkg/storage.(*store).init\n\t/src/loki/pkg/storage/store.go:164\ngithub.com/grafana/loki/pkg/storage.NewStore\n\t/src/loki/pkg/storage/store.go:147\ngithub.com/grafana/loki/pkg/loki.(*Loki).initStore\n\t/src/loki/pkg/loki/modules.go:655\ngithub.com/grafana/dskit/modules.(*Manager).initModule\n\t/src/loki/vendor/github.com/grafana/dskit/modules/modules.go:120\ngithub.com/grafana/dskit/modules.(*Manager).InitModuleServices\n\t/src/loki/vendor/github.com/grafana/dskit/modules/modules.go:92\ngithub.com/grafana/loki/pkg/loki.(*Loki).Run\n\t/src/loki/pkg/loki/loki.go:457\nmain.main\n\t/src/loki/cmd/loki/main.go:110\nruntime.main\n\t/usr/local/go/src/runtime/proc.go:250\nruntime.goexit\n\t/usr/local/go/src/runtime/asm_amd64.s:1598\nerror initialising module: store\ngithub.com/grafana/dskit/modules.(*Manager).initModule\n\t/src/loki/vendor/github.com/grafana/dskit/modules/modules.go:122\ngithub.com/grafana/dskit/modules.(*Manager).InitModuleServices\n\t/src/loki/vendor/github.com/grafana/dskit/modules/modules.go:92\ngithub.com/grafana/loki/pkg/loki.(*Loki).Run\n\t/src/loki/pkg/loki/loki.go:457\nmain.main\n\t/src/loki/cmd/loki/main.go:110\nruntime.main\n\t/usr/local/go/src/runtime/proc.go:250\nruntime.goexit\n\t/usr/local/go/src/runtime/asm_amd64.s:1598"

这是我在任务下

main.yml

文件中的部署部分：

              retention_period: 4464h

此外，我没有使用任何 PVC，而是使用 Blob 存储容器来发送我的 Loki 日志。 PVC 不是我的选择。

有人可以帮助我了解导致此错误的原因以及如何解决它吗？
