  • Bootstrap instances with specific software at start-up.

  • Download and update agents on a defined schedule, including the SSM Agent.

  • Configure network settings.

  • Join instances to a Windows domain (only Windows Server instances).

What is an association?

A State Manager association is a configuration that is assigned to your managed instances. The configuration defines the state that you want to maintain on your instances. For example, an association can specify that antivirus software must be installed and running on your instances, or that certain ports must be closed. The association specifies a schedule for when the configuration is applied once or reapplied at specified times. The association also specifies actions to take when applying thechef configuration. For example, an association for antivirus software might run once a day. If the software isn't installed, then State Manager installs it. If the software is installed, but the service isn't running, then the association might instruct State Manager to start the service.
