y1新建cluster集群redis

一、准备

y1的kubeconfig(脱敏)

apiVersion: v1
kind: Config
clusters:
- name: "yumc1-middleware"
  cluster:
    server: "https://ksrancher.hwwt2.com/k8s/clusters/c-4nmx8"
- name: "yumc1-middleware-172.25.148.232"
  cluster:
    server: "https://172.25.148.232:6443"
    certificate-authority-data: "xxx"
- name: "yumc1-middleware-172.25.148.231"
  cluster:
    server: "https://172.25.148.231:6443"
    certificate-authority-data: "xxx"
- name: "yumc1-middleware-172.25.148.233"
  cluster:
    server: "https://172.25.148.233:6443"
    certificate-authority-data: "xxx"

users:
- name: "yumc1-middleware"
  user:
    token: "xxx"

contexts:
- name: "yumc1-middleware"
  context:
    user: "yumc1-middleware"
    cluster: "yumc1-middleware"
- name: "yumc1-middleware-172.25.148.232"
  context:
    user: "yumc1-middleware"
    cluster: "yumc1-middleware-172.25.148.232"
- name: "yumc1-middleware-172.25.148.231"
  context:
    user: "yumc1-middleware"
    cluster: "yumc1-middleware-172.25.148.231"
- name: "yumc1-middleware-172.25.148.233"
  context:
    user: "yumc1-middleware"
    cluster: "yumc1-middleware-172.25.148.233"

current-context: "yumc1-middleware"

2. redis yaml文件

cluster模式的redis yaml文件

apiVersion: cache.tongdun.net/v1alpha1
kind: RedisCluster
metadata:
  name: redis-cluster-cpos-01  
  namespace: redis
spec:
  app: cluster-cpos-01  # 取name中redis-* 后的值, pod之间共享资源根据该标签
  capacity: 8192
  dc: sh
  env: production
  image: harbor.hwwt2.com/ops/redis-cluster:latest
  monitorimage: harbor.hwwt2.com/ops/redis-exporter:latest
  netmode: ClusterIP
  proxyimage: ""      # 原项目代理密码 废弃
  proxysecret: ""     # 原项目代理密码 废弃
  realname: dba 
  secret: 'TKYdUe7pfT'          # redis密码设置 可以为空
  size: 3             # 初始redis集群主节点 也是slot分段数量  单台节点最高容量32GB 所以如128GB,就是至少为4
  storageclass: ""    # 目前都是本地盘
  vip: ""             # 暂时废弃
  labels:              
    plt: cpos
    sid: "1115"
    srv: cpos-redis-cluster-gray 

注意：

Image 和 monitorimage ，y0和y1不是一样，需要注意。

y1_k8s	image: harbor.hwwt2.com/ops/redis-cluster:latest monitorimage: harbor.hwwt2.com/ops/redis-exporter:latest
y0_k8s	image: harbor.hwwt2.com/ops/redis-cluster:test0.3monitorimage: harbor.hwwt2.com/ops/redis-exporter:paas1.0

HA模式的redis yaml文件

apiVersion: cache.tongdun.net/v1alpha1
kind: RedisStandby
metadata:
  name: redis-standby-kfc-storeinfo
  namespace: redis
spec:
  app: standby-kfc-storeinfo
  capacity: 8192   # redis容量
  dc: sh
  env: production
  image: harbor.hwwt2.com/ops/op-redis-5.0.9:v2
  monitorimage: harbor.hwwt2.com/ops/redis-exporter:paas1.0
  netmode: ClusterIP
  realname: dba
  secret: '2ghlmvl_AP'
  sentinelimage: harbor.hwwt2.com/ops/sentinel-standby:v1
  storageclass: ''
  vip: ''
  labels:              # 百胜云监控需要的标签
    plt: ecselection
    sid: "1005"
    srv: ecselection-redis-kfc-storeinfo
---

3. git信息

redis的yaml文件记录在git中

code.hwwt2.com/osc/_source...

rancher地址

ksrancher.hwwt2.com/p/c-4nmx8:p...

二、操作

查询已有的redis

# 
kubectl --kubeconfig=yumc1_k8s get RedisCluster -n redis

2. 创建 redis（apply）

# cpos 是redis yaml文件
kubectl --kubeconfig=yumc1_k8s apply -f cpos

3. 验证

# 查看创建的 redis-cluster-cpos-01 资源
kubectl --kubeconfig=yumc1_k8s get RedisCluster -n redis

在rancher上验证

三、补充

1. 最小规格

分片：8G，三分片。

2. 规格套餐
3. 白皮书
4. 删除操作

# 删除redis-cluster-cpos01 资源
kubectl --kubeconfig=yumc1_k8s delete RedisCluster redis-cluster-cpos01 -n redis
