GCloud Home Directory Permissions for new users

Is there a way to override the default home directory permissions for new users on a compute engine instance?

I tried to modify /etc/adduser.conf, but it does not seem to be used for accounts created automatically when accessing the instance for the first time using the GCloud SDK.

You need to change the parameter UMASK in the file /etc/login.defs in order to change the default home directory permission for new users created from the GCloud SDK.

The value of UMASK for default is 022 that means rwx-rw--rw-,you can simply subtract the umask from the base permissions to determine the final permission for directory as follows: 777 – 022 = 755

Directory base permissions : 777 umask value : 022 Subtract to get permissions of new directory (777-022) : 755 (rwxr-xr-x)

The above is an example of value 022 but you can set your UMASK as you need, in this link you can find how to calculate the UMASK value https://www.cyberciti.biz/tips/understanding-linux-unix-umask-value-usage.html.
