K8s 应用 - Redis(集群)
以下是初始化Redis集群的步骤:
1. 创建一个Kubernetes集群,确保已经安装了Kubectl和Minikube。
2. 创建一个Redis镜像的Kubernetes deployment:
```
apiVersion: apps/v1
kind: Deployment
metadata:
name: redis
spec:
selector:
matchLabels:
app: redis
replicas: 3
template:
metadata:
labels:
app: redis
spec:
containers:
- name: redis
image: redis:5.0.5-alpine
ports:
- containerPort: 6379
command:
- redis-server
- --appendonly
- "yes"
```
3. 创建一个Redis集群的Kubernetes service:
```
apiVersion: v1
kind: Service
metadata:
name: redis
spec:
selector:
app: redis
ports:
- protocol: TCP
port: 6379
targetPort: 6379
clusterIP: None
```
4. 启动一个Kubernetes pod,用于初始化Redis集群:
```
apiVersion: v1
kind: Pod
metadata:
name: redis-init
spec:
containers:
- name: redis
image: redis:5.0.5-alpine
command:
- sh
- -c
- |
redis-cli --cluster create \
$(kubectl get pods -l app=redis -o jsonpath='{range.items[*]}{.status.podIP}:6379 ') \
--cluster-replicas 1
```
5. 等待Redis集群初始化完成,可以使用redis-cli验证集群状态:
```
$ redis-cli -c -p 6379
127.0.0.1:6379> cluster info
...
cluster_state:ok
...
```
以上就是初始化Redis集群的步骤。注意,在生产环境中,应该考虑更复杂的部署方案,例如使用持久化存储,设置密码等。
