We work on the shared folder, and create a file newfile from within a temporary container. NOTE: if you’re using something like docker on mac, you won’t run into those permission issues, as the file sharing is done through NFS and your local files will have the right user. mount 'type=bind,src=$(pwd)/shared,dst=/opt/shared' \ Here is a simple example of creating a new file with wrong permissions: $ docker run -it -rm \ Taking ownership of the files from your shared folder can be done with chown. It’s tedious and there is a better way: read on to learn learn how to build, configure and run your Docker containers correctly, so you don’t have to fight permission errors and access your files easily.įirst, let’s look at a “quick fix” which gets tedious quickly, before introducing better alternatives you want to use instead. One frequent solution, is to “chown” your shared folder again and again.

The file permissions and ownership are all wrong. The user of the container (root in the worst case) is completely different than the one on the host.

Is this what you see when accessing files that were created from within your Docker container? Avoiding Permission Issues With Docker-Created Files Permission denied
