在Kubernetes(K8s)中,可以通过使用Deployment对象来管理PHP应用程序,并配置自动故障恢复功能。以下是在Kubernetes中实现PHP应用故障自动恢复的步骤:
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
通过以上步骤,可以实现在Kubernetes集群中管理PHP应用程序,并配置自动故障恢复功能,以确保应用程序的高可用性和稳定性。
