二: 把路径 换了
这时在eclipse中直接运行就会发现已经可以识别图的内容了
原图
识别 结果:
三:把文件上传到服务 器之中,这个应该都会上传
上传以后,进行测试
执行命令 : java A
原图:
识别结果:
四:创建dockerfile
执行命令: vi Dockerfile
写以下内容:
五:通过dockerfile文件来创建镜像
执行命令: docker build -t 镜像名 . (注意后有个点)
六: 创建容器
因为我们的图片是服务器上的,也就是主机上的,所以容器是无法访问到图片,
这时要在创建容器时,要挂载宿主机的图片地址到镜像中
docker run --name photo_one -it -v /home/pi/dev/dev01/images:/home/pi/dev/dev01/images photo_huazy
可以看容器已经正常运行了
这时如果 执行ctrl + c 直接退出容器了,,如果 在创建容器时,在镜像前面 加上 - d 就不会退出了
六：查看
１：docker ps -a 就可以看到已经刚才的容器了
２：启动: docker start 容器名
３：查看状态 :ｄｏｃｋｅｒ ｐｓ
４：查看容器实时 日志 docker logs 容器名 -f -t
