在Kubernetes(K8s)中,可以通過使用Deployment對象來管理PHP應用程序,并配置自動故障恢復功能。以下是在Kubernetes中實現PHP應用故障自動恢復的步驟:
apiVersion: apps/v1
kind: Deployment
metadata:
name: php-app
spec:
replicas: 3
selector:
matchLabels:
app: php-app
template:
metadata:
labels:
app: php-app
spec:
containers:
- name: php-container
image: php:latest
ports:
- containerPort: 80
apiVersion: v1
kind: Pod
metadata:
name: php-app
spec:
containers:
- name: php-container
image: php:latest
ports:
- containerPort: 80
livenessProbe:
httpGet:
path: /
port: 80
initialDelaySeconds: 30
periodSeconds: 10
readinessProbe:
httpGet:
path: /
port: 80
initialDelaySeconds: 10
periodSeconds: 5
apiVersion: autoscaling/v2beta2
kind: HorizontalPodAutoscaler
metadata:
name: php-app
spec:
scaleTargetRef:
apiVersion: apps/v1
kind: Deployment
name: php-app
minReplicas: 3
maxReplicas: 10
metrics:
- type: Resource
resource:
name: cpu
targetAverageUtilization: 50
通過以上步驟,可以實現在Kubernetes集群中管理PHP應用程序,并配置自動故障恢復功能,以確保應用程序的高可用性和穩定性。
