1、配置helm redis repo
helm repo add bitnami https://charts.bitnami.com/bitnami
2 安装下载helm redis
下面是默认安装,不过前往别直接拿着下面安装命令就安装,官方默认安装的默认参数配置往往和我们实际场景不一样,需要配置一些参数
helm install my-redis bitnami/redis --version 18.7.0
2.1 下载helm redis
helm pull bitnami/redis --version 18.7.0
2.2 查看storageclass
如果环境中没有storageclass,就需自己安装存储支持或者采用云厂商的storageclass,内网环境推荐openebs,测试nfs就行了。
我的默认storageclass是openebs-hostpath,我的k8s环境上安装的openebs来做存储支持。当然如果有其他支持storageclass的也可以,比如nfs、云厂商sc,这里不做过多解释。
[root@k8s-master01 redis]# kubectl get storageclass
NAME PROVISIONER RECLAIMPOLICY VOLUMEBINDINGMODE ALLOWVOLUMEEXPANSION AGE
openebs-device openebs.io/local Delete WaitForFirstConsumer false 20d
openebs-hostpath (default) openebs.io/local Delete WaitForFirstConsumer false 20d
2.3 通过指定my-values.yaml安装
不过在这里因为是安装单机版,并且需要配置一些参数,所以需要通过--values配置一些参数
global:
storageClass: "openebs-hostpath"
redis:
password: "redis123"
architecture: standalone
commonConfiguration: |-
appendonly yes
save "300 10"
master:
resources:
limits:
cpu: 2
memory: 4Gi
requests:
cpu: 500m
memory: 2Gi
nodeSelector: {}
tolerations: []
persistence:
size: 10Gi
service:
type: NodePort
nodePorts:
redis: "30202"
- storageClass可以不用配置,因为我的默认storageClass已经配置。
- password 配置密码
- architecture 配置单机部署
- commonConfiguration 配置redis的存储策略
- master 主redis相关配置
安装前测试:
helm -n newland install redis -f my-values.yaml ./redis --dry-run
安装:
helm -n newland install redis -f my-values.yaml ./redis
2.4 直接修改values.yaml
我用的比较多的是直接修改values.yaml,修改的参数和上面的一样,找到对应的位置修改
安装测试:
[root@k8s-master01 redis]# helm install redis -n newland ../redis --dry-run
安装:
[root@k8s-master01 redis]# helm install redis -n newland ../redis
2.5 查看安装情况
helm查看安装:
[root@k8s-master01 redis]# helm list
NAME NAMESPACE REVISION UPDATED STATUS CHART APP VERSION
[root@k8s-master01 redis]# helm list -n newland
NAME NAMESPACE REVISION UPDATED STATUS CHART APP VERSION

查看k8s安装情况:
[root@k8s-master01 redis]# kubectl get pod -n newland

2.6 测试redis安装情况
[root@k8s-master01 redis]# kubectl exec -n newland redis-master-0 -it -- /bin/sh
$ redis-cli -a 密码
Warning: Using a password with '-a' or '-u' option on the command line interface may not be safe.
127.0.0.1:6379> get a
(nil)
通过测试可以看出安装成功了,我们本地需要连接redis直接使用nodeport端口30379,如果是k8s内直接使用service:6379就行了
