一、部署Redis到k8s上：通過資源管理建立

### --- 下載官方redis.conf配置模板：
~~~     官方地址：

[root@k8s-master01 redis]#  wget -c http://download.redis.io/redis-stable/redis.conf

### --- 取消配置檔案中的空格及註釋#號

[root@k8s-master01 redis]# grep -v "#" redis.conf |grep -v "^$"

### --- 獲取到的配置檔案引數如下

[root@k8s-master01 redis]# vim redis.conf 

bind 0.0.0.0
protected-mode yes
port 6379
tcp-backlog 511
timeout 0

pidfile /var/run/redis_6379.pid
loglevel notice
logfile "/tmp/redis.log"        # log日誌地址
databases 16
always-show-logo no
set-proc-title yes
proc-title-template "{title} {listen-addr} {server-mode}"
stop-writes-on-bgsave-error yes
rdbcompression yes
rdbchecksum yes
dbfilename dump.rdb
rdb-del-sync-files no
dir /data                       # dir地址更改為data
replica-serve-stale-data yes
replica-read-only yes
repl-diskless-sync no
repl-diskless-sync-delay 5
repl-diskless-load disabled
repl-disable-tcp-nodelay no
replica-priority 100
acllog-max-len 128
lazyfree-lazy-eviction no
lazyfree-lazy-expire no
lazyfree-lazy-server-del no
replica-lazy-flush no
lazyfree-lazy-user-del no

aof-use-rdb-preamble yes
lua-time-limit 5000
slowlog-log-slower-than 10000

set-max-intset-entries 512
zset-max-ziplist-entries 128
zset-max-ziplist-value 64
hll-sparse-max-bytes 3000

hz 10
dynamic-hz yes
aof-rewrite-incremental-fsync yes
rdb-save-incremental-fsync yes
jemalloc-bg-thread yes

二、建立redis-configmap：

### --- 建立redis-configmap：通過資源管理平臺來建立配置檔案，通過configmap的配置來修改

~~~     ——>建立configmap：資源配置——>ConfigMap——>選擇叢集：test1
~~~     ——>namespace:ratel-test1——>configmap名稱：redis-conf——>Data名稱：redis.conf
~~~     ——>資料：redis.conf模板——>Create——>END

三、建立redis-deployment

### --- 下載一個redis的5.0.4-alpine映象

[root@k8s-master01 redis]# docker images | grep redis
redis                                                             latest         bc8d70f9ef6c   5 days ago      105MB
redis                                                             5.0.4-alpine   631bf69df08e   2 years ago     50.9MB

### --- 建立redis-deployment

~~~     # 建立deployment：deployment——>
~~~     ——>Metadata：選擇叢集：test1——>Namespace：retal-test1——>Name：redis-single-node——>重啟策略——>Always——>DNS策略：ClusterFirst——>節點故障停留時間——>副本數：1——>儘量部署在不同宿主機上——>NEXT
~~~     ——>Volumes：volumes——>名稱：redis-conf——>Voume型別：ConfigMap——>ConfigMap名稱：redis-configmap——>Next

~~~     # ——>Containers：容器名稱：redis-single-node——>映象地址：redis:5.0.4-alpine
~~~     ——>啟動命令：sh,,,-c,,,redis-server"/mnt/redis.conf"
~~~     ——>Memory Request&limit（單位：Mi）：10~399
~~~     ——>LivenessProbe健康檢查：準備時間：10；檢查埠：6379；檢查方式：tcpSocket
~~~     ——>ReadinessProbe：準備時間：10；檢查埠：6379；檢查方式：tcpSocket
~~~     ——>映象下載策略：IfNotPresent——>容器埠：6379
~~~     ——>檔案掛載：Volume名稱：redis-conf；掛載目錄：/mnt；只讀：true——>Next

~~~     # ——>Init Containers：——>Next
~~~     ——>Services：新增Service——>預設——>Next
~~~     ——>Ingress：Create——>END

四、檢視建立的redis單節點pod

### --- 檢視啟動的redis的pod

[root@k8s-master01 redis]# kubectl get po -n ratel-test1 -owide
NAME                                READY   STATUS    RESTARTS   AGE   IP              NODE           NOMINATED NODE   READINESS GATES
redis-single-node-df78c5db8-jlbcn   1/1     Running   0          15m   172.25.92.115   k8s-master02   <none>           <none>

### --- 檢視啟動的svc

[root@k8s-master01 redis]# kubectl get svc -n ratel-test1 -owide
NAME                TYPE        CLUSTER-IP       EXTERNAL-IP   PORT(S)    AGE   SELECTOR
redis-single-node   ClusterIP   10.107.230.191   <none>        6379/TCP   41m   app=redis-single-node

### --- 檢視啟動的ep

[root@k8s-master01 redis]# kubectl get ep -n ratel-test1 -owide
NAME                ENDPOINTS            AGE
redis-single-node   172.25.92.115:6379   41m
