docker-maven-plugin 使用经验

无法打包镜像是本地没有docker环境，或者有环境未开启相应端口

其实有更新的插件，但是还不够稳，用起来没这个快，就先放放，后面加上。

推送镜像到私服被拒绝 解决步骤

1. 确认私服地址是否配置正确
2. 确认私服证书是否已安装，或者 dockerCertPath 配置是否正确
3. 确认在 maven 的 pom.xml 文件是否已配置认证账号
4. 干掉 ~/.docker/config.json，如果怕出事就备份下

# Dockerfile 文件内容
FROM amazoncorretto:17.0.5
#FROM amazoncorretto:17.0.5
# 将 target 下的 jar 包复制为 app.jar
ARG JAR_FILE=./target/*.jar
COPY ${JAR_FILE} /app.jar
# 声明服务运行在8080端口
EXPOSE 8080
# 指定docker容器启动时运行jar包
ENTRYPOINT ["java", "-jar","/app.jar"]
# 指定维护者的名字
