docker - 如何在Docker for Windows中浏览容器文件？我的文件夹映射不起作用

Question

我运行Windows机器，对docker还是 super 陌生，我正尝试在我的站点上为HomeAssistant设置LetsEncrypt。

我在Windows计算机中的C:/ Docker / LetsEncrypt中创建一个文件夹，然后运行此命令。

PS C:\Users\test> docker run -it --rm -p 80:80 --name certbot -v "C:Docker/LetsEncrypt/etc/letsencrypt:/etc/letsencrypt" -v "C:Docker/LetsEncrypt/var/lib/letsencrypt:/var/lib/letsencrypt" -v "C:Docker/LetsEncrypt/var/log/letsencrypt:/var/log/letsencrypt" quay.io/letsencrypt/letsencrypt:latest certonly --standalone --standalone-supported-challenges http-01 --email myemail@mail.com -d mysite.duckdns.org

这是我得到的结果

Warning: This Docker image will soon be switching to Alpine Linux.
You can switch now using the certbot/certbot repo on Docker Hub.
The standalone specific supported challenges flag is deprecated. Please use the --preferred-challenges flag instead.

IMPORTANT NOTES:
 - Congratulations! Your certificate and chain have been saved at:
   /etc/letsencrypt/live/mysite.duckdns.org/fullchain.pem
   Your key file has been saved at:
   /etc/letsencrypt/live/mysite.duckdns.org/privkey.pem
   Your cert will expire on 2018-06-22. To obtain a new or tweaked
   version of this certificate in the future, simply run certbot
   again. To non-interactively renew *all* of your certificates, run
   "certbot renew"
 - Your account credentials have been saved in your Certbot
   configuration directory at /etc/letsencrypt. You should make a
   secure backup of this folder now. This configuration directory will
   also contain certificates and private keys obtained by Certbot so
   making regular backups of this folder is ideal.
 - If you like Certbot, please consider supporting our work by:

   Donating to ISRG / Let's Encrypt:   https://letsencrypt.org/donate
   Donating to EFF:                    https://eff.org/donate-le  

看起来一切正常，除了我的Windows机器中找不到文件fullchaim.pem和privkey.pem，该文件位于C:\ Docker \ LetsEncrypt \ etc \ letsencrypt之内。

我想念什么？

Answer 1

这是您执行的命令

PS C:\Users\test> docker run -it --rm -p 80:80 --name certbot 
    -v "C:Docker/LetsEncrypt/etc/letsencrypt:/etc/letsencrypt" 
    -v "C:Docker/LetsEncrypt/var/lib/letsencrypt:/var/lib/letsencrypt" 
    -v "C:Docker/LetsEncrypt/var/log/letsencrypt:/var/log/letsencrypt" 
    quay.io/letsencrypt/letsencrypt:latest 
    certonly --standalone --standalone-supported-challenges 
    http-01 --email myemail@mail.com -d mysite.duckdns.org

docker允许您在本地计算机上安装目录，以便在启动的容器内部将相同的目录映射到新名称，但是目录内容相同。例如在上面说

    -v "C:Docker/LetsEncrypt/etc/letsencrypt:/etc/letsencrypt" 

这是一个卷对，其中:定界符的左侧是您的机器C:Docker/LetsEncrypt/etc/letsencrypt本地的目录，而右侧是根据/etc/letsencrypt从容器内部的透 View 调用同一目录的位置...此映射释放了容器的内部透 View 与给定人员的本地目录结构隔离...现在仔细查看此消息:

- Congratulations! Your certificate and chain have been saved at:
/etc/letsencrypt/live/mysite.duckdns.org/fullchain.pem

这是从容器内部的 Angular 来看的...所以现在您已经掌握了一些知识，可以发现丢失的 key 在哪里

解决方案在容器内时显示

/etc/letsencrypt/live/mysite.duckdns.org/fullchain.pem

该文件已映射到您本地计算机上的位置

C:Docker/LetsEncrypt/etc/letsencrypt/live/mysite.duckdns.org/fullchain.pem
