BUG: resolv.conf should be readable by non-root users

Hi

I saw this thread resolv.conf should be world-readable that is closed.
I just hit the same bug. I have a Container with an alpine image.
Running my app as non-root, it can’t resolve any hosts. After some troubleshooting I see that the resolv.conf is only readable by root.

$ fly ssh console -s -a my-app ? Select VM: arn: xxx
x:x:x:x xxxx
Connecting to x:x:x:x... complete
xxx:/var/lib/sftpgo# ls -l /etc/resolv.conf
-rwx------    1 root     root            20 Feb 18 20:22 /etc/resolv.conf

As a workaround I am running my app as root. But that is something I would like to avoid.
I’ved tried doing chmod 0644 /etc/resolv.conf in the container file also tried to replace the resolv.conf entierly via the container. But that doesn’t bite.

They solved their problem by switching to an non-alpine base image.
