Multiple users log into same VM as same "user"

[Steve Lorimer]

Hi all

I have multiple users connecting to the same VM using ssh.

I've added each user's ~/.ssh/id_rsa.pub file to metadata/ssh keys

They are all able to successfully login, but I'm hitting linux permissions problems when one user creates a file and another attempts to later write to it - as the file is not world writeable, and their user names and/or groups don't match.

How can I allow each user to log into the VM using a private key, but share the same user identity on the VM?

Thanks

Steve

add each user to a group, and set permissions with the group involved might work.

Hello Steve,

If a user presents their private SSH key, then they can use a third-party tool to connect to any instance that is configured with the matching public SSH key file, even if they are not a member of your Cloud Platform project. This article explains how to control access to Linux instances by creating SSH keys and editing public SSH key metadata.

Please note a private SSH key file that the user should stores on their local machines.
