To create a VPC using the Cloud Console, navigate to the VPCs page. This page lists all currently deployed VPCs along with their statuses.To open the VPC creation form, click the Create a VPC button on the top right of the screen.The configuration fields on this page include:
Value
Description
Name
Specify a name for the VPC.
Zone
A dropdown menu where you can select a Zone. A VPC must exist in the same Zone as the cluster it will be attached to. See Regions for more information.
Allow Public Prefix Announcement
Specifies whether the VPC should allow public prefixes advertised from Nodes to be imported into public facing networks, making them accessible from the Internet.
VPC Prefixes
A list of additional prefixes associated with the VPC. For example, CKS clusters use these prefixes for Pod and Service CIDR ranges.
Host Prefixes
Unique IPv4 IP ranges assigned to hosts in the VPC, validated for IPv4 CIDR format with prefix.
Custom DNS Servers
DNS servers announced via DHCP, validated for IP format.
A VPC requires at least three unique prefixes to be compatible with a CKS cluster. Prefixes cannot use any address in the RFC6598 (Carrier-Grade NAT) range of 100.64.0.0/10.For example, your VPC prefixes could be something like this:
Prefix
Description
10.0.0.0/13
Pod CIDR Range
10.16.0.0/22
Service CIDR Range
10.16.4.0/22
Internal Load Balancer CIDR Range
Click the Add a Prefix button.The New VPC Prefix window opens, where you can enter the prefix details.Additional configuration settings for the VPC are found under Advanced Settings.
Value
Description
Disable External Propagate
Disables external propagation for this prefix, preventing the advertisement of the address space to external networks.
You can add additional Host Prefixes at any time, but you cannot remove an existing Host Prefix.
Host prefixes define the IP address ranges assigned to the Nodes within a VPC, which are used for network communications between Nodes and other resources within the VPC. To add a new range of host IP addresses, click the Add a Prefix button to open the New Host Prefix window.Each CoreWeave features a default Host Prefix, which is assigned automatically unless a different prefix is specified. The default Host Prefixes for each AZ are:
SUNK users take note: If network.hostPrefixes is supplied, it should have a minimum prefix length of /18. Prefixes smaller than /18 do not have physical location based IP addresses which are used for calculating adjacency.
The VPCs page displays a list of your current VPCs and their statuses.You can sort VPCs by Name, Zone, Age, or Status. Use the arrow buttons near each field to sort the list accordingly.
To make changes to an existing VPC, click the vertical ellipse menu button to the right of the VPC’s name. Then, click the Edit button.This opens the Edit VPC window, which includes all the same options presented in the Create VPC window.
