Docker compose 容器中的空文件，使用docker compose with volumes初始化现有文件的映像

我正在尝试使用现有的配置文件初始化容器。我拥有的文件是nginx.conf和ssl.conf。卷配置设置如下：

volumes:
      - ./nginxletsencrypt_config:/config
      - ./nginxConfig/nginx.conf:/config/nginx/site-confs/default
      - ./nginxConfig/ssl.conf:/config/nginx/ssl.conf

这个结果是“default”和ssl.conf文件，它们具有root:root所有者，甚至被标记为可执行文件。如果我只放第一行，并注释掉nginx.conf和ssl.conf的另外两行，那么图像中就有这两个文件，其中包含它们的默认内容。 完整的docker compose文件是：

version: '2'
services:
    nginx:
        restart: always
        image: linuxserver/letsencrypt
        container_name: nginx
        ports:
          - 443:443
          - 80:80
        cap_add:
          - NET_ADMIN
        environment:
          - HOST_HOSTNAME=prod
          - PUID=1001 # get on dockerhost through command "id <user>"
          - PGID=1002
          - TZ=Europe/London
          - URL=domainname.com
          - VALIDATION=http
          - EMAIL=contact@email.fr
          - STAGING=false
        volumes:
          - ./nginxletsencrypt_config:/config
          - ./nginxConfig/nginx.conf:/config/nginx/site-confs/default
          - ./nginxConfig/ssl.conf:/config/nginx/ssl.conf

=============================================

将docker更新至最新版本并在clear Environment上测试后（以前未安装旧的docker）：

表示“默认”文件不为空。然后文件被复制了。但为什么我不能将其与

cat ./nginxletsencrypt_config/nginx/site-confs/default

或

---

所以我可以复制你的问题

$cat nginxletsencrypt\u config/nginx/site confs/default
$ls-ialh nginxletsencrypt\u config/nginx/site confs/default
23518410-rwxr-xr-x 1 tarunlalwani staff 0B Jul 9 12:37 nginxletsencrypt_config/nginx/site confs/default
$ls-ialh nginxConfig/nginx.conf
23492731-rw-rw-r--@1 tarunlalwani staff 22B Jul 8 13:14 nginxConfig/nginx.conf
$docker compose exec nginx sh
root@9d6d58328d33：/#ls-alhi-config/nginx/site-confs/default
23492731-rw-rw-r--1 abc abc 22 Jul 8 08:44 config/nginx/site confs/default
root@9d6d58328d33:/#

正如您所看到的，

nginxletsencrypt\u config

中的

inode

是不同的，因此它是一个空白文件。我的直觉是，这是因为容器中的文件系统层

---

这是docker的一个错误吗？可能是的，或者这可能是一种特殊情况，需要更深入地理解为什么会发生这种情况

My be您将在无法使用

docker compose

1.23.2版进行复制时获得更多帮助。当容器启动时，卷按预期工作，文件也在其中。是否有任何特殊原因导致您在

docker compose

文件顶部省略了

version

？另外，请确保卷部分中的主机路径有效（无误）。因此，您不需要

root:root

permissions？@TarunLalwani root:root，如果文件正确复制且内容在其中，则不会出现问题。目前它们是空的。我想根用户就是问题所在。这些文件可能首先是从具有根所有者的容器中创建的，然后作为另一个用户运行对这些文件的写入。虽然我不明白为什么文件首先创建为空，而不是直接与内容一起复制。@makkasi，我在Ubuntu 16.04上尝试过，但无法重现您的问题，请参见屏幕截图
