springboot部署到k8s步骤
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
上篇文章已讲过 springboot构建docker镜像并推送到阿里云
创建secret
登录私有仓库需要创建secret，存储docker registry的认证信息
创建secret
~$ 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
创建deployment的yaml文件
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: {}
~$修改k8sdemo.yaml文件
#1.修改副本数量为2
#2.挂在secret
apiVersion: apps/v1
kind: Deployment
metadata:
creationTimestamp: null
labels:
app: k8sdemo
name: k8sdemo
spec:
replicas: 2
selector:
matchLabels:
app: k8sdemo
strategy: {}
template:
metadata:
creationTimestamp: null
labels:
app: k8sdemo
spec:
imagePullSecrets:
- name: fdf-docker-secret
containers:
- image: registry.cn-chengdu.aliyuncs.com/fandf/k8s-test:1.0.0
name: k8s-test
resources: {}
status: {}创建deployment
~$ 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创建service, nodePort
#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
