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
此结果是“ 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。如果仅将第一行放进去，然后将nginx.conf和ssl.conf的另外两行注释掉，那么该映像中将包含这两个文件及其默认内容。 完整的docker compose文件为：
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
我使用linuxserver / letsencrypt来获得ssl证书。在手动将nginx.conf内容放入“默认”文件后，我设法运行了所有内容，并且证书和nginx正常工作。 Docker撰写版本

这里的用户：$ {CURRENT_UID}是1001：1002，但是有了这个，如果没有这个，在〜/ test / nginxletsencrypt_config / nginx目录中运行“ sudo cat ssl.conf”后，ssl.conf文件是空文件。 / p>
=================新编辑
我看到了nginx的日志，并且有这个
nginx | nginx: [emerg] host not found in upstream "web:8000" in /config/nginx/site-confs/default:2
表示“默认”文件不为空。然后文件被复制。但是为什么我不能用
列出它cat ./nginxletsencrypt_config/nginx/site-confs/default
或
sudo cat ./nginxletsencrypt_config/nginx/site-confs/default
答案 0 :(得分：2)
所以我能够重现您的问题
$ cat nginxletsencrypt_config/nginx/site-confs/default
$ ls -ialh nginxletsencrypt_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:/#
您可以看到inodes中的nginxletsencrypt_config有所不同，因此它是一个空白文件。我的直觉是因为容器中文件系统的层数。
这是Docker中的错误吗？可能是的，或者这可能是一个特例，需要对它发生的原因有更深入的了解
