Deploy Virtual Servers via the Cloud UI
The CoreWeave Cloud UI is a responsive, Web-based dashboard enabling users to configure, deploy, and manage Virtual Servers. To view, manage, and deploy Virtual Servers in the Cloud UI, navigate to Virtual Servers from the left-hand menu.
If there are already existing Virtual Servers in the active namespace, they are listed here in the menu, just below the page header. Expand a Virtual Server's details by clicking the downward arrow beside its name. This view offers further information about the selected machine, such as the data center in which it is hosted, its host DNS name, its external IP address, the cost it incurs per hour, and more.
There are several different ways to deploy a Virtual Server - each method may suit a different use case. If this is your first time creating a Virtual Server, start by creating a brand new Virtual Server.
Create a brand new Virtual Server
If you haven't ever created a Virtual Server before, start here.
A new deployment is a blank slate. All settings are configured from scratch in order to build a custom-configured Virtual Server.
Create a Virtual Server from a template
If this is your first Virtual Server, it is recommended to begin by initiating a brand new configuration, using the Cloud UI to configure the Server.
At this time, when deploying a new Virtual Server, you may be asked if you'd like to try the new deploy form:
While both methods are functional, the following documentation covers deployment using the VS Deploy in Cloud options.
To start, navigate to the Virtual Servers page from the left-hand navigation of the Cloud UI, or click the Deploy Now button found in the Deploy Virtual Server box in the center of the homepage.
There are two quick ways to navigate to the Virtual Servers main screen from the homepage
All Virtual Servers are managed from the Virtual Servers page. Here, all existing Servers are listed, alongside the option to deploy new ones. To create a new Virtual Server, click the New Virtual Server button.
If you have no Virtual Servers, none will be listed - click "New Virtual Server" to create the first Server
Virtual Servers are configured and deployed from the New Virtual Server page. When creating a brand new Virtual Server, all configurations are manually selected here in order to create a machine custom-tailored to your needs.
The creation page consists of two panes: a Web UI on the right, and a YAML manifest editor on the left, revealed by clicking Edit YAML on the right-hand side of the screen.
The YAML editor gives the creator direct access to the Custom Resource Definition (CRD) that defines the Virtual Server object in Kubernetes, providing a high level of flexible customization and transparency. Exposing the Virtual Server's manifest also offers an opportunity for programmatic deployment via the Kubernetes CLI.
Changes made using either the GUI or the YAML editor are automatically reflected on both sides. For example, changing the name of the Virtual Server in the GUI's Name field automatically updates the value in the YAML manifest's
To hide the YAML editor from view, click Hide YAML. This tab transforms into Edit YAML once closed, and may be clicked again to re-open the YAML editor pane.
Sensitive values such as passwords are obscured by asterisks in the YAML editor when entered in the Cloud UI editor. Clicking on the YAML editor will reveal the entered password in the manifest.
The Web UI with the YAML editor open
Beside the page header, there are three buttons in the upper-right corner of the Web UI pane.
- The magic wand button reverts the current form to the last valid configuration.
- The arrow button resets the current form by clearing all fields.
The deployment page does not allow cloning running Servers. Be sure to shut down the source server before creating a clone of it.
A clone is a snapshot of an existing Virtual Server that includes the PVC containing the OS and all files. This means that deploying a clone of a Virtual Server creates an exact duplicate of an existing Virtual Server in the same state the original is in at the time the clone is created.
There are two ways to create Virtual Server clones.
From the New Virtual Server form, click Load or clone from existing in the upper-right to open the Select Template modal.
Select an existing Virtual Server in the drop-down given. Then, toggle the Clone (use resource as source) option to create an exact clone of the selected Virtual Server.
Toggle "Clone (use resource as source)" to clone a Virtual Server
Another way to deploy a clone is to choose a Server from the primary list on the Virtual Servers main page. To the right of the Virtual Server's detail pane is an ellipsis menu. Clicking it reveals further options, including Clone and, separately, Use as Template.
Changes to the cloned configuration may be made after the clone is created.
A template uses an existing Virtual Server as a model. Creating a new Virtual Server from a template creates a new Server using the same configuration as the selected source Server, but it does not copy the state of the source machine or the source machine's data the way cloning does.
The steps to deploy a Virtual Server from a template are similar to deploying a clone, but instead of toggling the Clone (use resource as source) option to the "on" position, ensure it is in the "off" position, and that the deployment button's text reads Use as template.
Clicking this button will automatically configure the form settings on the Virtual Server creation page to match those of the machine used as its source. Changes to the copied configuration may be made once the configuration is copied into the editor.
If configuration changes to the new Server are desired, it is generally safer to create a copy of a Server from a template rather than from a clone because templates do not copy the files or state of the source Server.
Leave Clone untoggled to create a Virtual Server template
A custom deployment loads the Operating System image from an existing PVC or from a remote HTTP source.
To deploy a custom Virtual Server, begin by following the same steps as if deploying a brand new Virtual Server. In the Operating System section of the configuration screen, select either Image From Remote Source for an HTTP source, or Image From PVC to load an OS from a PVC.
Choose a Custom option
In the Image From a Remote Source box, enter the URL of an OS in the text field provided in the box. Operating System images may be in
isoformats, and may optionally compressed with either
This option will not be shown if there are no eligible PVCs deployed in your namespace. Ensure the source Server is shut down before using its PVC as an image source for a new Server.
There are several additional tools in the Cloud UI for managing Virtual Servers.
Click the Virtual Server to expand its menu for more information and to see all options.
The status page also offers access to a virtual terminal, which provides immediate access to the Virtual Server through a VNC terminal once the Server is in a ready state. To open the virtual terminal, click the Terminal button in the Virtual Server's expanded menu, or click the ellipses on the right hand side of its name and select Terminal.
Clicking the Upgrade button redirects to the Hardware Selection page described above. From here, options such as GPU type, CPU core amounts, root disk size, may be adjusted.
For Virtual Servers running Windows, it may take time to install and upgrade the OS. Additionally, the Web-based terminal is not supported by Virtual Servers utilizing custom EDID.
The Events page is a basic diagnostic log of all actions involving the Virtual Server are recorded in a list, viewed by clicking the Events button.
The events listed under Events are short-lived, so should mostly be used for diagnostic purposes or for tracing the status of the Virtual Server.
Click any of the specification cards to learn more about each Virtual Server configuration option.
