1.创建nginx.yaml文件
apiVersion: apps/v1
kind: Deployment
metadata:
name: nginx-deployment
spec:
selector:
matchLabels:
app: nginx
replicas: 2 # 告知 Deployment 运行 2 个与该模板匹配的 Pod
template:
metadata:
labels:
app: nginx
spec:
containers:
- name: nginx
image: nginx:1.14.2
ports:
- containerPort: 80
kubectl apply -f nginx.yaml
可以通过以下命令伸缩容器
kubectl scale deployment nginx-deployment --replicas=1
#当然也可以使用下面的命令更改参数进行缩容或者扩容
kubectl edit deployment nginx-deployment
