Hooks

Hooks provide a way to be notified of certain events during the operation of the Razor server; the behavior of a hook is defined by a hook type.

File layout for a hook type

Similar to brokers and tasks, hook types are defined through a .hook directory and files within that directory:

      layout: table
        columns:

Today

The main point of interaction between server and microkernel is the /svc/checkin/:id endpoint. It currently expects that the Microkernel peridoically posts the following JSON to that URL:

{
  "facts": { ... facts hash ... }
}
