首先你需要構建 docker 鏡像，並且 push 到 registry 參考這裡
創建密鑰
kubectl create secret docker-registry docker-hub \ --docker-server=https://index.docker.io/v1/ \ --docker-username=netkiller \ --docker-password=passw0rd \ --docker-email=netkiller@msn.com
查看是否創建成功
iMac:spring neo$ kubectl get secret NAME TYPE DATA AGE default-token-fhfn8 kubernetes.io/service-account-token 3 2d23h docker-hub kubernetes.io/dockerconfigjson 1 15s
springboot.yml 編排腳本
apiVersion: v1
kind: Service
metadata:
name: springboot
namespace: default
labels:
app: springboot

ports:
- port: 8888
nodePort: 30000
selector:

apiVersion: apps/v1
kind: Deployment
metadata:

spec:
replicas: 3

iMac:spring neo$ kubectl create -f springboot.yml deployment.apps/springboot created iMac:spring neo$ kubectl expose deployment springboot --type="LoadBalancer" service/springboot exposed iMac:spring neo$ minikube service list |----------------------|---------------------------|--------------|---------------------------| | NAMESPACE | NAME | TARGET PORT | URL | |----------------------|---------------------------|--------------|---------------------------| | default | kubernetes | No node port | | default | springboot | 8888 | http://192.168.64.2:30000 | | kube-system | kube-dns | No node port | | kube-system | registry | No node port | | kubernetes-dashboard | dashboard-metrics-scraper | No node port | | kubernetes-dashboard | kubernetes-dashboard | No node port | |----------------------|---------------------------|--------------|---------------------------| iMac:spring neo$ minikube service springboot --url http://192.168.64.2:30000
http://192.168.64.2:30000 是訪問地址，Kubernetes 會負載均衡到後面的三個 pod 上。
iMac:config neo$ curl -k https://config:s3cr3t@192.168.64.2:30000/netkiller-dev.json
{"sms":{"gateway":{"url":"https://sms.netkiller.cn/v1","username":"netkiller","password":"123456"}}}
刪除服務
iMac:spring neo$ kubectl delete -f springboot.yml service "springboot" deleted deployment.apps "springboot" deleted
