kubernetes - 无法使用 k8ssandra 部署 Cassandra

Question

我正在使用下图将 Cassandra 集群部署到我的 gke 集群。 https://github.com/k8ssandra/k8ssandra/tree/main/charts/k8ssandra

然而，statefulset 停留在状态 1/2(cassandra 容器状态始终不健康)

这是我的 values.yaml

cassandra:
  auth:
    superuser: 
      secret: cassandra-admin-secret
  clusterName: cassandra-cluster
  version: "4.0.0"
  cassandraLibDirVolume:
    storageClass: standard
    size: 5Gi
  allowMultipleNodesPerWorker: true
  resources:
    requests:
      cpu: 500m
      memory: 2Gi
    limits:
      cpu: 500m
      memory: 2Gi
  datacenters:
  - name: dc1
    size: 1
    racks:
    - name: default 

stargate:
  enabled: true
  replicas: 1
  heapMB: 256
  cpuReqMillicores: 200
  cpuLimMillicores: 500

kube-prometheus-stack:
  enabled: False

NAME                                                READY   STATUS     RESTARTS   AGE
cassandra-cluster-dc1-default-sts-0          1/2     Running    0          77m

然后我描述了pod

Events:
  Type     Reason     Age                    From     Message
  ----     ------     ----                   ----     -------
  Warning  Unhealthy  2m11s (x478 over 81m)  kubelet  Readiness probe failed: HTTP probe failed with statuscode: 500

最后，我打印了cassandra容器的日志。

INFO  [nioEventLoopGroup-2-2] 2022-04-20 11:09:35,711 Cli.java:617 - address=/10.12.11.58:51000 url=/api/v0/metadata/endpoints status=500 Internal Server Error

和server-system-logger的日志

tail: cannot open '/var/log/cassandra/system.log' for reading: No such file or directory

我该如何解决这个问题？谢谢。

Answer 1

cassandra 容器中的消息说，一旦 Cassandra 启动并运行，它应该自行解决，这是正确的。

同样，在 Cassandra 启动之前，server-system-logger 容器没有可用的日志，更准确地说，在日志框架初始化之前。
