Spring Boot 2.3.0发布了支持了build-image，但是由于墙的问题，本人一直没有尝试成功

jib（https://github.com/GoogleContainerTools/jib）是google发布的镜像构建工具，详细介绍和使用方法，可以看官方网站

注意事项

• 假如项目中存在多个包含main函数的类，需要指定运行主类
• 在mac中，假如出现安装了docker，但是提示为找到docker时，可以在mvn运行加上参数jib.dockerClient.executable=/usr/local/bin/docker

pom.xml中配置jib

构建本地镜像

mvn compile jib:dockerBuild

启动运行容器，其中CONSUL_HOST，DB_HOST，DB_PORT，DB_USERNAME，DB_PASSWORD，KAFKA_BROKERS是在bootstrap.yml中自定义的变量（对应为consul.host，db.host，db.port，db.username，db.password，kafka.brokers），SPRING_CLOUD_CONSUL_DISCOVERY_IP_ADDRESS本身为Spring Cloud的配置

docker run --name app-service-local -p 8002:8002 -e CONSUL_HOST={consul地址} -e SPRING_CLOUD_CONSUL_DISCOVERY_IP_ADDRESS={用于服务发现的IP地址} -e DB_HOST={数据库地址} -e DB_PORT={数据库端口} -e DB_USERNAME={数据库用户名} -e DB_PASSWORD={数据库密码} -e KAFKA_BROKERS={kafka地址} --restart always -d app-service:2.2.8.RELEASE
