Target Environment Requirements
Credentials
Except for the Is Package Installed operation, Accounts used when executing jobs against operations contained within this package must adhere to the following requirements:
- The target machine must have a local admin user that will be used for running the operations;
You must enable* SSH Remote Login for the user above
- Configuration for the user must be added to the sudoers file on the target machine to allow the above user to sudo without a password (example: __someadminuser ALL = (ALL) NOPASSWD:ALL__).
KeySafe Configuration
When creating SIS jobs for operations within this package, they need to be run on the target machine as a user who has the correct privileges.
To configure your Target Machine account authentication in KeySafe:
- In the Admin console, navigate to: System > Security > KeySafe;
- Click on + then select
Username + Password
; - Give the KeySafe Key a Title (this is the name/identifier for the target machine account as you will see it when creating an IT Automation Job or adding an IT Automation node to a Business Process or Runbook);
- Optionally add a description;
- Populate the Username field with the domain/local account username for the account being used on the target machine;
- Populate the Password field with the password for the above account;
- Select Create Key to save.
Once you have created your KeySafe Key, you can use it when creating IT Automation Jobs from this package. See screenshots to the right for examples.
