如何在docker中以非root用户身份写入卷容器？ [英] How do I write to a volume container as non-root in docker?

问题描述

如何挂载非root容器用户可写的卷？我可以将非root用户拥有的卷或将权限设置为777。

How do I mount a volume writable by a non-root container user? I am ok with either the volume being owned by the non-root user or permissions being set to 777.

Dockerfile：

Dockerfile:

FROM alpine
RUN adduser -D myuser
USER myuser

构建映像：

docker build -t example .

运行图像，查看/ app用户不可写

Run image, see /app unwritable by user

% docker run -i -t -v myapp:/app example /bin/sh
/ $ whoami
myuser
/ $ ls -lha / | grep app
drwxr-xr-x    2 root     root        4.0K Nov 12 21:01 app
/ $ 

我们可以看到该应用程序是全局可读的，但只能由root用户写入。

We can see app is globally readable but only writable by root.

推荐答案

尚不支持，并在问题2259 中进行了研究。

会影响其他图像像 docker-java 。

That is not yet supported, and is studied in issue 2259.
That affect other images like docker-java.

基本上，您必须小丑并复制（使用正确的用户）卷中的数据，这不是很方便。

Basically, you have to chown and copy (with the right user) your data in the volume, which is not very convenient.
