Managing Compute Nodes
----------------------

Nodes in the compute cluster are shown on the **NODES** tab.

Clicking a node, you can see the following information about it:

-  node CPU and RAM usage,

-  node name, status, and IP address,

-  hosted virtual machines and their resource consumption.

The next subsections describe how to add nodes to and remove nodes from the compute cluster.

.. _Adding Nodes to Compute Cluster:

Adding Nodes to Compute Cluster
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

To add one or more nodes to your compute cluster, do the following:

#. Click **Add node** on the **NODES** tab.

#. On the **Add node** panel, select nodes to add to the compute cluster and click **Add**.

      :align: center
      :class: align-center

#. If required, configure network on each node: click the cogwheel icon, assign networks to node NICs to cover the required traffic types, and click **Apply**.

The added nodes will appear on the **NODES** tab.

.. _Releasing Nodes from Compute Cluster:

Releasing Nodes from Compute Cluster
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

.. warning:: When a node is released from the compute cluster, all virtual machines hosted on it are destroyed. To keep them, migrate them to other compute nodes first.

To release one or more nodes from the compute cluster, do the following:

#. On the **NODES** tab, either

   -  select the nodes and click **Release nodes** above the list, or
   -  click the ellipsis icon next to a node and select **Release**, or
   -  click a node to open its details, then click **Release node** on the top toolbar.

#. In the **Release node** window, confirm the action by clicking **Remove**.

The selected nodes will disappear from the **NODES** tab.
