Adding SSH credentials
Add SSH credentials to use for connecting to the target machines being managed by LCM.
Add SSH credentials to connect to target machines being managed by Lifecycle Manager (LCM).
The Login User and SSH Login options allow LCM to remotely log in to a machine over SSH using a password or private key. LCM requires superuser privileges to install software and manage configurations on a target machine. The Escalate Privileges options allow specifying SU or SUDO mechanisms to elevate privileges if necessary after the remote login.
All passwords and private keys are encrypted and safely stored by Lifecycle Manager.
