今天小编给大家分享一下springboot项目怎么部署到k8s上的相关知识点,内容详细,逻辑清晰,相信大部分人都还太了解这方面的知识,所以分享这篇文章给大家参考一下,希望大家阅读完这篇文章后有所收获,下面我们一起来了解一下吧。
springboot项目打包镜像部署到镜像仓库
登录私有镜像仓库,拉去镜像
创建deployment
暴露服务访问端口
登录私有仓库需要创建secret,存储docker registry的认证信息
~$ kubectl create secret docker-registry fdf-docker-secret --docker-server=registry.cn-chengdu.aliyuncs.com --docker-username=17602117026 --docker-password=用户密码 secret/fdf-docker-secret created ~$ ~$ ~$ kubectl get secret NAME TYPE DATA AGE fdf-docker-secret kubernetes.io/dockerconfigjson 1 15s
创建好之后,后续需要挂载到pod上
快速创建一个deployment,导出yaml文件
~$ kubectl create deployment k8sdemo --image=registry.cn-chengdu.aliyuncs.com/fandf/k8s-test:1.0.0 --dry-run=client -o yaml > k8sdemo.yaml ~$ cat k8sdemo.yaml apiVersion: apps/v1 kind: Deployment metadata: creationTimestamp: null labels: app: k8sdemo name: k8sdemo spec: replicas: 1 selector: matchLabels: app: k8sdemo strategy: {} template: metadata: creationTimestamp: null labels: app: k8sdemo spec: containers: - image: registry.cn-chengdu.aliyuncs.com/fandf/k8s-test:1.0.0 name: k8s-test resources: {} status: {} ~$
修改k8sdemo.yaml文件
#1.修改副本数量为2 #2.挂在secret apiVersion: apps/v1 kind: Deployment metadata: creationTimestamp: null labels: app: k8sdemo name: k8sdemo spec: replicas: 2 selector: matchLabels: app: k8sdemo strategy: {} template: metadata: creationTimestamp: null labels: app: k8sdemo spec: imagePullSecrets: - name: fdf-docker-secret containers: - image: registry.cn-chengdu.aliyuncs.com/fandf/k8s-test:1.0.0 name: k8s-test resources: {} status: {}
~$ kubectl apply -f k8sdemo.yaml deployment.apps/k8sdemo created ~$ kubectl get deploy NAME READY UP-TO-DATE AVAILABLE AGE k8sdemo 0/2 2 0 12s ~$ kubectl get deploy NAME READY UP-TO-DATE AVAILABLE AGE k8sdemo 2/2 2 2 24s ~$ kubectl get pod NAME READY STATUS RESTARTS AGE k8sdemo-65d45fb49f-l4kx5 1/1 Running 0 28s k8sdemo-65d45fb49f-pqsjw 1/1 Running 0 28s
#port 服务端口 target-port pod端口 ~$ kubectl expose deploy k8sdemo --port=9001 --target-port=9001 --type=NodePort service/k8sdemo exposed ~$ ~$ kubectl get svc k8sdemo NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE k8sdemo NodePort 10.96.10.79 <none> 9001:31921/TCP 12s ~$ curl http://127.0.0.1:31921/api/v1/user/name zhangsan
可以看到serviced的ip为10.96.10.79 对外端口为 31921,安全组需开放该端口才能访问
到这里我们服务部署就算完成了,看一下所有的节点
~$ kubectl get secret,pod,svc,deploy NAME TYPE DATA AGE secret/fdf-docker-secret kubernetes.io/dockerconfigjson 1 52m NAME READY STATUS RESTARTS AGE pod/k8sdemo-65d45fb49f-l4kx5 1/1 Running 0 39m pod/k8sdemo-65d45fb49f-pqsjw 1/1 Running 0 39m NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE service/k8sdemo NodePort 10.96.10.79 <none> 9001:31921/TCP 5m51s service/kubernetes ClusterIP 10.96.0.1 <none> 443/TCP 301d NAME READY UP-TO-DATE AVAILABLE AGE deployment.apps/k8sdemo 2/2 2 2 39m ~$
