java应用运行在docker，并且其他组件也在docker

docker启动redis容器

# create redis
docker run -d --name redis-container -p 6379:6379 redis:latest

创建java 应用

dockerfile

FROM  openjdk:17##Pre-create related directories
RUN mkdir -p /data/etax/ms-app
WORKDIR /data/etax/ms-appEXPOSE 10133
COPY ./target/fe-msv-ntp-ms3-1.0.0-SNAPSHOT.jar /data/etax/ms-app/app.jar
ENTRYPOINT ["java","-jar","app.jar"]

构建命令

# docker build
docker build -t test-docker:v3 ./# app
docker run -d --name test-docker-app -p 10133:10133 test-docker:v3

SpringBoot 项目搭建

启动类

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;@SpringBootApplication
public class AppApplication {public static void main(String[] args) {SpringApplication.run(AppApplication.class, args);}
}
