Run agent locally
In this section you will:
Let’s connect to our Rudder server by SSH:
vagrant ssh server sudo -i # to get a root access
We will use the
rudder command that gives access to all Rudder actions.
But first, let’s explain a bit how things work on the agent. We saw that the server generates an applicable configuration that contains the expected state of the machine.
The agent that runs on all of these machines will download the latest version of its policies, and apply them locally. To trigger this process manually, run:
rudder agent update # to update the policies rom the server rudder agent run # to apply these policies locally
This will display the state of all applied components, including the ones you have defined before.
The rest of the components are called system techniques, you can ignore them for now. They are responsible for maintaining the Rudder services themselves, and hence are not editable by users.
Let’s get back to the web interface, on the dashboard (click on the Dashboard link in the left menu, or directly on the Rudder logo):
You can see that compliance information got back to the server, and is used to display the current state in the dashboard.
Now you can go to our node details by using the quick search filter, and searching for "node".
Go to the "Compliance reports" tab. You will see the applied policy and the current compliance regarding it. If you click on a line it will unfold until you get to the actual applied component.
We have now finished our first policy application, from definition, using a new technique or a built-in one, to the actual application on our Rudder server.
We will now dig a bit deeper on what the policy mode (we modified) is, and how to use it.
