1.准备好需要准备的springboot项目，新建Dockerfile文件

#Dockerfile文件内容
FROM openjdk:8-jdk-alpine 
ADD ./target/wechart-0.0.1-SNAPSHOT.jar app.jar
EXPOSE 8080 
ENTRYPOINT ["java","-jar","/app.jar"]

            
            
                com.spotify
                dockerfile-maven-plugin
                1.3.6
                
                   ${project.artifactId}
                
            

2.新建阿里云镜像仓库

3.新建githup仓库，根据提示，推送代码

 4.新建访问秘钥TOKEN

5.配置项目所需要的环境信息，找到项目下的setting设置，点击secrets，开始配置

TOKEN为刚新建的令牌

6.在.githubworkflows文件夹下新建yml文件
