部署service
1.创建 deployment
student@ubuntu:~/job$cat nginx-one.yaml
apiVersion: extensions/v1beta1
kind: Deployment
metadata:
name: nginx-one
labels:
system: secondary
spec:
replicas: 2
template:
metadata:
labels:
app: nginx
spec:
containers:
- image: nginx
imagePullPolicy: Always
name: nginx
ports:
- containerPort: 80
protocol: TCP
student@ubuntu:~/job$kubectl create -f nginx-one.yaml
- 创建service
student@ubuntu:~/job$kubectl expose deployment nginx-one
service/nginx-one exposed
student@ubuntu:~/job$kubectl get svc
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
kubernetes ClusterIP 10.96.0.1 <none> 443/TCP 5d17h
nginx-one ClusterIP 10.106.204.175 <none> 80/TCP 4s
student@ubuntu:~/job$curl 10.106.204.175
<!DOCTYPE html>
<html>
<head>
<title>Welcome to nginx!</title>
<style>
body {
width: 35em;
配置NodePort
student@ubuntu:~/job$kubectl expose deployment nginx-one --name=nginx-node-port --type=NodePort
service/nginx-node-port exposed
student@ubuntu:~/job$kubectl get svc
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
kubernetes ClusterIP 10.96.0.1 <none> 443/TCP 5d17h
nginx-node-port NodePort 10.101.146.38 <none> 80:31555/TCP 3s
nginx-one ClusterIP 10.106.204.175 <none> 80/TCP 99s
使用label管理资源
1.删除pod
student@ubuntu:~/addons/efk$kubectl get pod --show-labels
NAME READY STATUS RESTARTS AGE LABELS
nginx-one-c5b5c6f7c-l569b 1/1 Running 0 17m app=nginx,pod-template-hash=c5b5c6f7c
nginx-one-c5b5c6f7c-xf2gj 1/1 Running 0 17m app=nginx,pod-template-hash=c5b5c6f7c
student@ubuntu:~/addons/efk$kubectl delete pod -l app=nginx
pod "nginx-one-c5b5c6f7c-l569b" deleted
pod "nginx-one-c5b5c6f7c-xf2gj" deleted
2.删除deployment
student@ubuntu:~/addons/efk$kubectl get deployments. --show-labels
NAME DESIRED CURRENT UP-TO-DATE AVAILABLE AGE LABELS
nginx-one 2 2 2 2 21m system=secondary
student@ubuntu:~/addons/efk$kubectl get deployments. --show-labels
NAME DESIRED CURRENT UP-TO-DATE AVAILABLE AGE LABELS
nginx-one 2 2 2 2 21m system=secondary
3.给资源添加标签
student@ubuntu:~/addons/efk$kubectl get nodes --show-labels
NAME STATUS ROLES AGE VERSION LABELS
node-193 Ready worker 5d16h v1.12.1 beta.kubernetes.io/arch=amd64,beta.kubernetes.io/fluentd-ds-ready=true,beta.kubernetes.io/os=linux,kubernetes.io/hostname=node-193,node-role.kubernetes.io/worker=
ubuntu Ready master 5d17h v1.12.1 beta.kubernetes.io/arch=amd64,beta.kubernetes.io/fluentd-ds-ready=true,beta.kubernetes.io/os=linux,kubernetes.io/hostname=ubuntu,node-role.kubernetes.io/master=
student@ubuntu:~/addons/efk$kubectl label nodes key=value
error: resource(s) were provided, but no name, label selector, or --all flag specified
student@ubuntu:~/addons/efk$kubectl label nodes ubuntu key=value
node/ubuntu labeled
student@ubuntu:~/addons/efk$kubectl get nodes --show-labels
NAME STATUS ROLES AGE VERSION LABELS
