在Kubernetes中,可以通过配置Pod的控制器来实现容器的自动转移。以下是一些常用的方法:
apiVersion: apps/v1
kind: Deployment
metadata:
name: my-deployment
spec:
replicas: 3
selector:
matchLabels:
app: my-app
template:
metadata:
labels:
app: my-app
spec:
containers:
- name: my-container
image: my-image
apiVersion: apps/v1
kind: DaemonSet
metadata:
name: my-daemonset
spec:
selector:
matchLabels:
app: my-app
template:
metadata:
labels:
app: my-app
spec:
containers:
- name: my-container
image: my-image
apiVersion: apps/v1
kind: StatefulSet
metadata:
name: my-statefulset
spec:
replicas: 3
selector:
matchLabels:
app: my-app
template:
metadata:
labels:
app: my-app
spec:
containers:
- name: my-container
image: my-image
通过以上配置,Kubernetes可以在节点故障时自动将Pod转移到其他节点,保证应用程序的高可用性。
