Permissions Issues when running nasher init on docker volume

[deltreey]

I ran into a weird issue where running the command instructed in the README would error constantly:

docker run --rm -v $(pwd):/nasher squattingmonk/nasher:latest init --default

The error was as follows:

Initializing into /nasher
Creating package file at /nasher/nasher.cfg
Error: Cannot open /nasher/nasher.cfg
Error: Could not create package file at /nasher/nasher.cfg

After 2 days of fighting with it, I found that setting permissions was unreliable, but forcing docker to run under the current uid did work:

docker run --rm -u `id -u $USER` -v $(pwd):/nasher squattingmonk/nasher:latest init --default

Not sure if the preferred solution is to simply update the docs, but here ya go!
