minikube部署应用并访问(minikube安装)

windows、docker、minikube

minikube tunnel

另起一个终端，创建deployment，设置服务类型LoadBalancer，使用官方镜像内部端口80

kubectl create deployment my-nginx --image=nginx:latest
kubectl expose deployment my-nginx --type=LoadBalancer --port=80
kubectl get svc

此时tunnel

访问外部ip+端口localhost:80

创建一个springboot应用的demo
编写pom.xml

	
        myspringbootk8simage
        
            
                org.springframework.boot
                spring-boot-maven-plugin
                2.4.2
            
            
            
                com.spotify
                docker-maven-plugin
                1.0.0
                
                    ${project.artifactId}
                    
                        1.0.1
                    
                    src/main/docker
                    
                        
                            /
                            ${project.build.directory}
                            ${project.build.finalName}.jar
                        
                    
                
            
            
        
    

写一个控制器

@RestController
public class HelloController {
    @RequestMapping("/hello")
    public String hello(){
        return "hello minikube";
    }
}

Dockerfile

FROM openjdk:8-jdk-alpine
VOLUME /tmp
#将myspringbootk8simage.jar复制到容器内部 并且别名叫myspringbootk8simage.jar
ADD myspringbootk8simage.jar myspringbootk8simage.jar
#相当于在容器中用cmd命令执行jar包  指定外部配置文件
ENTRYPOINT ["java","-jar","/myspringbootk8simage.jar"]

maven打个包

Build Success后，在Dockerfile文件所在目录打开终端，创建镜像

docker build -t springboot-k8s . 

将镜像push到docker hub

docker login
docker tag springboot-k8s sunzhexun/springboot-k8s
docker push sunzhexun/springboot-k8s

部署到minikube(tunnel要保持开启)

 kubectl create deployment hello-k8s --image=sunzhexun/springboot-k8s:1.0
 kubectl expose deployment hello-k8s --type=LoadBalancer --port=8080
 kubectl get deployments
 kubectl get svc

minikube dashboard

通过外部ip访问
