本文主要是介绍初试Docker desktop与OpenVINO DL Workbench的使用入门，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
一，初试Docker desktop
你可以使用WIN+R 输入powershell启动powershell，也可以用anaconda的powershell 快捷方式，我选择用anaconda-powershell，进入命令界面后开始测试
运行: docker --version
(base) PS C:\Users\space> docker --version
Docker version 19.03.8, build afacb8b
从Docker Hub中拉出hello-world映像并运行一个容器: docker run hello-world
(base) PS C:\Users\space> docker run hello-world
Unable to find image 'hello-world:latest' locally
latest: Pulling from library/hello-world
0e03bdcc26d7: Pull complete Digest: sha256:d58e752213a51785838f9eed2b7a498ffa1cb3aa7f946dda11af39286c3db9a9
Status: Downloaded newer image for hello-world:latest
Hello from Docker!
This message shows that your installation appears to be working correctly.
To generate this message, Docker took the following steps:
1. The Docker client contacted the Docker daemon.
2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
(amd64)
3. The Docker daemon created a new container from that image which runs the
executable that produces the output you are currently reading.
4. The Docker daemon streamed that output to the Docker client, which sent it
to your terminal.
To try something more ambitious, you can run an Ubuntu container with:
$ docker run -it ubuntu bash
Share images, automate workflows, and more with a free Docker ID:
https://hub.docker.com/
For more examples and ideas, visit:
https://docs.docker.com/get-started/

设置
关于设置这里就不多说了，因为docker desktop有图形化的设置界面，很容易找到各个要设置的选项。
二，OpenVINO DL Workbench的使用入门
根据OpenVINO官方文档
参考：https://docs.openvinotoolkit.org/latest/_docs_Workbench_DG_Install_from_Docker_Hub.html#windows
在ubuntu和windows下的操作稍有不同，但大同小异，我以windows为例，
首先，打开powershell 命令窗口，输入命令
docker run -p 127.0.0.1:5665:5665 --name workbench -it openvino/workbench:latest如果一切正常的话，docker会帮你把文件包从Docker Hub上拉到本地，大概结果如下，
PS C:\Users\space> docker run -p 127.0.0.1:5665:5665 --name workbench -it openvino/workbench:latest
Unable to find image 'openvino/workbench:latest' locally
latest: Pulling from openvino/workbench
5bed26d33875: Pull complete
f11b29a9c730: Pull complete
930bda195c84: Pull complete
78bf9a5ad49e: Pull complete
。。。这里有好多包，省略
f45b6c5bd647: Pull complete
Digest: sha256:546ffa3ca4469a7b2f2df40da6b7258b997136bef033e183d89f35a99ee0f32a
Status: Downloaded newer image for openvino/workbench:latest
。。。又省略一大段内容
2020-06-19 11:31:40.149 UTC [14] LOG: redo done at 0/1636940
2020-06-19 11:31:40.149 UTC [14] LOG: last completed transaction was at log time 2020-06-04 17:02:56.370138+00

[E:] [BSL] found 0 ioexpander device这时，系统提示你可以进入服务器了，打开浏览器，输入
http://127.0.0.1:5665.
可以看到OpenVINO workbench界面，
在命令窗口按Ctrl + C （事际上我是先后用Ctrl + Z ---- Ctrl + C）可以停止workbench服务。
然后在命令窗口创建文件夹：
mkdir C:\workbench
根据官网的说法，再运行
docker run -p 127.0.0.1:5665:5665 --name workbench --volume /C/workbench:/home/openvino/.workbench -d openvino/workbench:latest报错：冲突，已经在使用中：
PS C:\Users\space> docker run -p 127.0.0.1:5665:5665 --name workbench --volume /C/workbench:/home/openvino/.workbench -d openvino/workbench:latest
C:\Program Files\Docker\Docker\resources\bin\docker.exe: Error response from daemon: Conflict. The container name "/workbench" is already in use by container "4e283c7e0bd2397f32ec7413543574d74f55602c913630462c46b121aeba35b4". You have to remove (or rename) that container to be able to reuse that name.
See 'C:\Program Files\Docker\Docker\resources\bin\docker.exe run --help'.
PS C:\Users\space>
下面是我的处理方法，
（1）先查看一下当前状态
PS C:\Users\space> docker ps -a
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
4e283c7e0bd2 openvino/workbench:latest "bash /opt/intel/ope…" 2 hours ago Up 2 hours 127.0.0.1:5665->5665/tcp workbench
22583a1d1487 ubuntu "bash" 2 hours ago Exited (127) 2 hours ago romantic_cannon
447ed27e3e03 hello-world "/hello" 2 hours ago Exited (0) 2 hours ago trusting_neumann
（2）这时候执行docker rm是不成功的，
PS C:\Users\space> docker rm 4e283c
Error response from daemon: You cannot remove a running container 4e283c7e0bd2397f32ec7413543574d74f55602c913630462c46b121aeba35b4. Stop the container before attempting removal or force remove
（3）这时只能先用docker stop停止服务
PS C:\Users\space> docker stop 4e283c
4e283c
（4）然后再移除该container才可以，
PS C:\Users\space> docker rm 4e283c
4e283c
（5）这样，就可以顺利重新启动container了，
PS C:\Users\space> docker run -p 127.0.0.1:5665:5665 --name workbench --volume /C/workbench:/home/openvino/.workbench -d openvino/workbench:latest
b26f548fbdca3f6ed2fcb140c438d9cd48f96bb27f07f66e4f09391374db617b
当然，假设不用docker rm的话，用docker start ...也是可以的，官网里并没有具体介绍，我通常就是这么干的。另外，特别注意，那个登陆的token不会再在powershell命令窗口显示，现在已经保存到这里了，
C:\workbench\token.txt
最后，晒一张登陆成功的图片吧！
