无法将配置目录挂载到Nextcloud Docker容器中 [英] Cannot mount Config directory in Nextcloud Docker container

问题描述

我正在尝试在本地创建自定义的Nextcloud配置，然后能够使用此处定义的卷将其安装到适当的文件夹中:

I'm trying to create a custom Nextcloud config locally, then have the ability to mount it to the appropriate folder using volumes as defined here: https://github.com/nextcloud/docker#persistent-data. All the volume mounts work except for the config mount... Why is that being treated differently here?

0)输入一个新的/空目录(不包含子目录或其他文件).

0) Enter a new/emptry directory (containing no sub-directories or additional files).

1)创建一个仅包含以下内容的docker-compose.yml文件:

1) Create a docker-compose.yml file containing only the below contents:

version: "3.4"

services:
  nextcloud:
    image: nextcloud:latest
    volumes:
      - "./nextcloud/custom_apps:/var/www/html/custom_apps"
      - "./nextcloud/config:/var/www/html/config"
      - "/data/nextcloud:/var/www/html/data"
      - "./themes:/var/www/html/themes"

2)docker-compose up -d

2) docker-compose up -d

工作.我应该能够在./nextcloud/config本地查看/var/www/html/config的内容，然后插入客户config.php，然后在容器内对其进行更新.

Work. I should be able to see the /var/www/html/config contents locally at ./nextcloud/config, and then insert a customer config.php, which is then updated within the container.

启动容器时出现错误，特定于 config 目录.如果删除上面的./nextcloud/config:/var/www/html/config卷安装，则容器将启动而不会出现错误.

An ERROR when bringing up the container, specific to the config directory. If I remove the ./nextcloud/config:/var/www/html/config volume mount above, then the container will start without error.

推荐答案

我无法使用您的步骤进行复制(Ubuntu 18.04).

I could not reproduce using your steps (Ubuntu 18.04).

从这里开始依次运行docker-compose up -d和docker-compose logs，我看不到任何错误.然后，在容器上运行docker inspect时，我看到以下内容:

From here, running docker-compose up -d then docker-compose logs, I see no errors. Then, when running docker inspect on the container, I see the following:

...
"Volumes": {
    "/var/www/html": {},
    "/var/www/html/config": {},
    "/var/www/html/custom_apps": {},
    "/var/www/html/data": {},
    "/var/www/html/themes": {}
},
...

这表明安装座工作正常.

Which suggests the mount has worked without problem.

我建议您做什么:

1. 检查目录./nextcloud/config存在并且不是文件
2. 检查您的Docker和Docker Compose安装是最新的
3. 尝试使用docker run -it -v ./nextcloud/config:/var/www/html/config <containername> /bin/bash运行Docker容器，以了解安装是否可以手动工作
4. 尝试在一个最小的示例上执行相同的操作，例如入门示例

1. Check the directory ./nextcloud/config exists and is not a file
2. Check your Docker and Docker Compose installation is up-to-date
3. Try running the Docker container with docker run -it -v ./nextcloud/config:/var/www/html/config <containername> /bin/bash to explore if the mount works manually
4. Try to do the same on a minimal example such as the Getting started example
