Passwordless access for the service accounts is set up using the SSH key pair. Such accounts are usually labeled appropriately to point to the related automation. A service account is a headless account that is not associated with any real user. Service accounts are set up to access hosts remotely without having to input password. We will look at more complex scenarios that may be needed for automation after that.įollowing are the basic strategies involved (there could be any number of variations): Let’s look at some basic SSH usages first. SSH configuration for a user can be configured to get around that issue securely. It is very obvious that such interactive sessions are not feasible in an automated transaction. Doing such tasks using SSH is not difficult when done manually, in which case the user will be prompted for a password or passphrase. A very common example is running a script on a remote machine via SSH. ![]() Such access would normally involve providing credentials in the form of a password or key to login to the remote machine. In an automated job, the scripts used by it may have to access remote machines for fetching information from them or running programs on them. A common setup that DevOps engineers have to do as part of automation projects is configuring passwordless access to remote machines.
