public class DisplaySecretReconciler extends org.jgrapes.core.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.

    • DisplaySecretReconciler

      public DisplaySecretReconciler(org.jgrapes.core.Channel componentChannel)
      Instantiates a new display secret reconciler.
      Parameters:
      componentChannel - the component channel

  • Method Details

    • onConfigurationUpdate

      @Handler public void onConfigurationUpdate(org.jgrapes.util.events.ConfigurationUpdate event)
      On configuration update.
      Parameters:
      event - the event

    • reconcile

      public void reconcile(VmDefinition vmDef, Map<String,Object> model, VmChannel channel, boolean specChanged) throws IOException, freemarker.template.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:
      vmDef - the VM definition
      model - the model
      channel - the channel
      specChanged - the spec changed
      Throws:
      IOException - Signals that an I/O exception has occurred.
      freemarker.template.TemplateException - the template exception
      io.kubernetes.client.openapi.ApiException - the api exception

    • onGetDisplaySecret

      @Handler public void onGetDisplaySecret(GetDisplaySecret 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
      channel - the channel
      Throws:
      io.kubernetes.client.openapi.ApiException - the api exception

    • onVmResourceChanged

      @Handler public void onVmResourceChanged(VmResourceChanged event, org.jgrapes.core.Channel channel)
      On vm def changed.
      Parameters:
      event - the event
      channel - the channel
