提问by Alex
I want to create a docker image with seleniumand chromecorrectly installed, so I choose a base image with these properties. Therefore, the first line of the Dockerfileis as follows:
我想创建一个码头工人形象与selenium和chrome正确安装，所以我选择具有这些特性的基础图像。因此，第一行Dockerfile如下：
FROM selenium/node-chrome:3.7.1-argon
Then the next command is
然后下一个命令是
RUN apt-get update
which created the following error while creating the docker image:

As hinted by:
正如所暗示的：
Acquire (13: Permission denied)
获取（13：权限被拒绝）
I believe this is due to your base image:
我相信这是由于您的基本图像：
https://github.com/SeleniumHQ/docker-selenium/blob/master/NodeChrome/Dockerfile
https://github.com/SeleniumHQ/docker-selenium/blob/master/NodeChrome/Dockerfile
As you can see it swaps from the default user context of 'root' to 'seluser'.
如您所见，它从“root”的默认用户上下文切换到“seluser”。
You can either:
您可以：
- wear this as a consequence of the base image (i.e. use sudo)
- swap back:
USER root - or consider creating your own docker image to avoid swapping in the first place
- 作为基础图像的结果佩戴它（即使用 sudo）
- 换回：
USER root - 或者考虑创建自己的 docker 镜像以避免首先交换
Hope that helps mate.
