Folder Permission in Alpine images are not root group writeable

[vbasem]

The folder permissions for /var/lib/arangodb3 /var/lib/arangodb3* are not being properly set to 775 as mentioned in the Dockerfile:

echo chgrp -R 0 /var/lib/arangodb3 /var/lib/arangodb3-apps && \
echo chmod -R 775 /var/lib/arangodb3 /var/lib/arangodb3-apps &

The echo is rendering the command ineffective. This causes environments that disallow root user to fail when starting the ID container which needs to write to those folders which only have read permission by default.

I fixed it locally by rebuilding the image by simply removing the echo in the 2 commands above.

Was the echo on purpose?

Hello @vbasem,

This was fixed in d46dfa8 and soon will appear at https://hub.docker.com/_/arangodb?tab=description.

To make the directories root writeable on a image is not a good idea. Usually root it's prohibited (by psp) to run a image as root.
As well, it's a bad practice to write to image filesystem as well!
