Module are responsible for achieving desired external system states based on a resource in Entropy.
This is how the module interface looks like:
type Module interface {
Plan(ctx context.Context, spec Spec, act ActionRequest) (*resource.Resource, error)
Sync(ctx context.Context, spec Spec) (*resource.State, error)
}
Every Module has a Plan and a Sync method which plays it's part in the resource lifecycle.
Entropy currently support firehose and kubernetes modules, with more lined up.
