Redis集群HA在kubernetes中不起作用

Question

我使用以下命令部署了https://github.com/bitnami/charts/tree/master/bitnami/redis-cluster

helm install redis-cluster bitnami/redis-cluster --create-namespace -n redis -f redis-values.yaml

redis-values.yaml

cluster:
  init: true
  nodes: 6
  replicas: 1

podDisruptionBudget:
  minAvailable: 2

persistence:
  size: 1Gi

password: "redis@pass"

redis:
  configmap: |-
    maxmemory 600mb
    maxmemory-policy allkeys-lru
    maxclients 40000
    cluster-require-full-coverage no
    cluster-allow-reads-when-down yes

sysctlImage:
  enabled: true
  mountHostSys: true
  command:
    - /bin/sh
    - -c
    - |-
      insta
      sysctl -w net.core.somaxconn=10000
      echo never > /host-sys/kernel/mm/transparent_hugepage/enabled
#      echo never > /host-sys/kernel/mm/transparent_hugepage/defrag


metrics:
  enabled: true

现在集群工作正常，但是如果我要删除任何pod，那么redis就会关闭，我开始收到redis的错误。

以下是我用于连接quarkus的配置：

quarkus.redis.hosts=redis://redis-cluster.redis.svc.local:6379
quarkus.redis.master-name=redis-cluster
quarkus.redis.password=redis@pass
quarkus.redis.client-type=cluster

Answer 1

不与服务连接，但使用节点更改自

quarkus.redis.hosts=redis://redis-cluster:6379

至

quarkus.redis.hosts=redis://redis-cluster-0.redis-cluster-headless.redis.svc.cluster.local:6379,redis://redis-cluster-1.redis-cluster-headless.redis.svc.cluster.local:6379,redis://redis-cluster-2.redis-cluster-headless.redis.svc.cluster.local:6379,redis://redis-cluster-3.redis-cluster-headless.redis.svc.cluster.local:6379,redis://redis-cluster-4.redis-cluster-headless.redis.svc.cluster.local:6379,redis://redis-cluster-5.redis-cluster-headless.redis.svc.cluster.local:6379

主机的格式如下：POD-NAME.HEADLESS-SVC-NAME.NAMESPACE.svc.cluster.local:PORT
