Class Resource (1.6.0)

Resource(mapping=None, *, ignore_unknown_fields=False, **kwargs)

An OS policy resource is used to define the desired state configuration and provides a specific functionality like installing/removing packages, executing a script etc.

The system ensures that resources are always in their desired state by taking necessary actions if they have drifted from their desired state.

Classes

ExecResource

ExecResource(mapping=None, *, ignore_unknown_fields=False, **kwargs)

A resource that allows executing scripts on the VM.

The ExecResource has 2 stages: validate and enforce and both stages accept a script as an argument to execute.

When the ExecResource is applied by the agent, it first executes the script in the validate stage. The validate stage can signal that the ExecResource is already in the desired state by returning an exit code of 100. If the ExecResource is not in the desired state, it should return an exit code of 101. Any other exit code returned by this stage is considered an error.

If the ExecResource is not in the desired state based on the exit code from the validate stage, the agent proceeds to execute the script from the enforce stage. If the ExecResource is already in the desired state, the enforce stage will not be run. Similar to validate stage, the enforce stage should return an exit code of 100 to indicate that the resource in now in its desired state. Any other exit code is considered an error.

NOTE: An exit code of 100 was chosen over 0 (and 101 vs 1) to have an explicit indicator of in desired state, not in desired state and errors. Because, for example, Powershell will always return an exit code of 0 unless an exit statement is provided in the script. So, for reasons of consistency and being explicit, exit codes 100 and 101 were chosen.
