K8S Redis 連接

我已經為 HA Redis 安裝了 Bitnami Helm Chart： https ://bitnami.com/stack/redis/helm

aleg@Azure:~$ kubectl get pods | grep redis
redis-1580896952-master-0                              1/1     Running   0         67m
redis-1580896952-slave-0                               1/1     Running   0          67m
redis-1580896952-slave-1                               1/1     Running   0          65m

aleg@Azure:~$ kubectl get svc | grep redis
redis-1580896952-headless             ClusterIP      None           <none>          6379/TCP                     67m
redis-1580896952-master               ClusterIP      10.0.244.169   <none>          6379/TCP                     67m
redis-1580896952-slave                ClusterIP      10.0.250.136   <none>          6379/TCP                     67m

我應該如何連接它？服務或主控吊艙或其他什麼？請指教。

範例：使用 Redis 部署 PHP 留言板應用程序很好地解釋了這一點。

解釋了整個設置過程，然後設置和公開留言簿前端描述瞭如何公開服務於 HTTP 請求的 Web 前端。它被配置為連接到redis-master寫入請求的redis-slave服務和讀取請求的服務。

範例deployment如下所示：

apiVersion: apps/v1 # for versions before 1.9.0 use apps/v1beta2
kind: Deployment
metadata:
 name: frontend
 labels:
   app: guestbook
spec:
 selector:
   matchLabels:
     app: guestbook
     tier: frontend
 replicas: 3
 template:
   metadata:
     labels:
       app: guestbook
       tier: frontend
   spec:
     containers:
     - name: php-redis
       image: gcr.io/google-samples/gb-frontend:v4
       resources:
         requests:
           cpu: 100m
           memory: 100Mi
       env:
       - name: GET_HOSTS_FROM
         value: dns
         # Using `GET_HOSTS_FROM=dns` requires your cluster to
         # provide a dns service. As of Kubernetes 1.3, DNS is a built-in
         # service launched automatically. However, if the cluster you are using
         # does not have a built-in DNS service, you can instead
         # access an environment variable to find the master
         # service's host. To do so, comment out the 'value: dns' line above, and
         # uncomment the line below:
         # value: env
       ports:
       - containerPort: 80

使用該設置，您只需要創建前端服務：

apiVersion: v1
kind: Service
metadata:
 name: frontend
 labels:
   app: guestbook
   tier: frontend
spec:
 # comment or delete the following line if you want to use a LoadBalancer
 type: NodePort 
 # if your cluster supports it, uncomment the following to automatically create
 # an external load-balanced IP for the frontend service.
 # type: LoadBalancer
 ports:
 - port: 80
 selector:
   app: guestbook
   tier: frontend

我建議閱讀有關Redis的文件。
