5.5 构建项目运行基础应用容器镜像
在harbor-server主机上操作
5.5.1 创建项目目录
[root@harbor-server ~]# mkdir tomcatdir
[root@harbor-server ~]# cd tomcatdir
5.5.2 生成Dockerfile文件
[root@harbor-server tomcatdir]# echo "tomcat is running" >> index.html
[root@harbor-server tomcatdir]# vim Dockerfile
[root@harbor-server tomcatdir]# cat Dockerfile

5.5.3 使用docker build构建容器镜像
[root@harbor-server tomcatdir]# docker build -t 192.168.10.23/library/tomcat:8575 .
5.5.4 推送容器镜像至harbor容器镜像仓库
[root@harbor-server tomcatdir]# docker images

5.6 项目构建及发布
5.6.1 项目构建及发布步骤
第一步：jenkins获取项目代码
第二步：jenkins对项目代码编译，由maven完成
第三步：jenkins使用docker对编译完成的项目代码进行打包，打包成容器应用镜像
第四步：jenkins把打包的容器应用镜像上传到harbor
第五步：jenkins通过ssh插件完成对web-server进行运行容器应用镜像的操作
5.6.2 创建项目任务
Dockerfile：
REPOSITORY=192.168.10.23/library/solo:${Tag}
# 构建镜像
cat > Dockerfile << EOF
