public class DisplaySecretReconciler
extends Component

The properties of the display secret do not only depend on the VM definition, but also on events that occur during runtime.

The reconciler for the display secret is therefore a separate component.

The reconciler supports the following configuration properties:

• passwordValidity: the validity of the random password in seconds. Used to calculate the password expiry time in the generated secret.

public DisplaySecretReconciler(Channel componentChannel)

Instantiates a new display secret reconciler.

@Handler
public void onConfigurationUpdate(ConfigurationUpdate event)

On configuration update.

Parameters:

event - the event

reconcile

public void reconcile(VmDefChanged event,
 Map<String,Object> model,
 VmChannel channel)
               throws IOException,
TemplateException,
io.kubernetes.client.openapi.ApiException

Reconcile.

If the configuration prevents generating a secret or the secret already exists, do nothing. Else generate a new secret with a random password and immediate expiration, thus preventing access to the display.

Parameters:

event - the event

model - the model

channel - the channel

Throws:

IOException - Signals that an I/O exception has occurred.

TemplateException - the template exception

io.kubernetes.client.openapi.ApiException - the api exception

onPrepareConsole

@Handler
public void onPrepareConsole(PrepareConsole event,
 VmChannel channel)
                      throws io.kubernetes.client.openapi.ApiException

Prepares access to the console for the user from the event.

Generates a new password and sends it to the runner. Requests the VM (via the runner) to login the user if specified in the event.

Parameters:

event - the event

Throws:

io.kubernetes.client.openapi.ApiException - the api exception

onVmDefChanged

@Handler
public void onVmDefChanged(VmDefChanged event,
