I use Windows 10 home on my PC and SSHing to up to 5 Linux IaaS machines with either Debian/ArchLinux as server environments.
I use Ansible to orchestrate and continuously integrate and continuously upgrade data in these remote server environments.
I consider using the same SSH private key for both WSL-Ansible and Putty (or WSL-OpenSSH for that matter).
The user for both Ansible and Putty/SSH is a sudoer.
Is that problematic?
