在docker中已装入卷中的权限被拒绝

Question

I'm mounting a volume from my local host in a docker container using docker-compose (added the volumes entry id docker-compose.yml)

This works well, but when I try to run py.test I get permission errors:

OSError: [Errno 13] Permission denied: '/foo/bar/.coverage' etc

Also, when I try to create the .coverage dir when I'm logged in to the container I get:

mkdir .coverage
mkdir: cannot create directory '.coverage': Permission denied

Any ideas on how to solve this?

Answer 1

You can do anything (like a volume mount) in the docker container as long as the Docker itself has the right permission. You should exec your container using following:

docker exec -it -u 0 Container_NAME /bin/bash

And then execute py.test, I just hope you're not doing su - to some user within py.test

这可能是由于该目录上的文件上下文，尝试将其更改为“沙盒”文件：

chcon -Rt svirt_sandbox_file_t /foo/bar/

Answer 3

Got the same issue and fixed it by adding a chmod -R 777 in my Dockerfile (adapt 777 to your permissions but you need a read/write) on the root folder of my test package (foo/bar/ in your case). I made it recursive because I run my test coverage in my sub-folders as well.
