单yaml 文件多资源共存
同一个 yaml 文件中包含多资源的写法,比如deployment, service ,pv 等
以deployment 和service 并存为例
deployment 和 service 文件
deployment 文件
kubectl run tomcat11 --image=registry.cn-hangzhou.aliyuncs.com/misa/tomcat:9.0 --replicas=2 --port=8080 --dry-run -o yaml > deploy.yaml
[root@master1 feng]# cat deploy.yaml
apiVersion: extensions/v1beta1
kind: Deployment
metadata:
creationTimestamp: null
labels:
run: tomcat11
name: tomcat11
spec:
replicas: 2
selector:
matchLabels:
run: tomcat11
strategy: {}
template:
metadata:
creationTimestamp: null
labels:
run: tomcat11
spec:
containers:
- image: registry.cn-hangzhou.aliyuncs.com/misa/tomcat:9.0
name: tomcat11
ports:
- containerPort: 8080
resources: {}
status: {}
service 文件
kubectl expose deployment tomcat11 --port=8080 --type=NodePort --dry-run -o yaml > svc.yaml
[root@master1 feng]# cat svc.yaml
apiVersion: v1
kind: Service
metadata:
creationTimestamp: null
labels:
run: tomcat11
name: tomcat11
spec:
ports:
- port: 8080
protocol: TCP
targetPort: 8080
selector:
run: tomcat11
type: NodePort
status:
loadBalancer: {}
合并方式1
两个对象中间用 --- 隔开,不然会只能识别到一个
[root@master1 feng]# cat svc.yaml >> add.yaml
[root@master1 feng]# echo "---" >> add.yaml
[root@master1 feng]# cat deploy.yaml >> add.yaml
[root@master1 feng]# kubectl create -f add.yaml
service "tomcat11" created
deployment.extensions "tomcat11" created
合并方式2
用 kind: List 来定义集合,将其他对象,deployment, service,pvc 等作为子项。
注意 deployment service 等子项每行前面再加2给空格。
[root@master1 feng]# cat deploy.yaml >> add2.yaml
[root@master1 feng]# cat svc.yaml >> add2.yaml
# 每行前面插入2个空格
[root@master1 feng]# sed -i 's/^/ /g' add2.yaml
vim add2.yaml
增加前三行内容
子项的 apiVersion 行首的第一个空格换成 -
[root@master1 feng]# kubectl create -f add2.yaml
deployment.extensions "tomcat11" created
service "tomcat11" created
[root@master1 feng]# cat add2.yaml
apiVersion: v1
kind: List
items:
