|Management Endpoint||✓||Hostname/IP address of Prism Central|
|Username||✓||Username of the Prism Central user|

Choose what Nutanix cluster the virtual machine will be scheduled to.
|Cluster||✓||Name of the Nutanix cluster where the VM should be deployed (case sensitive)|
In the Instance Options section, configure the number of vCPUs, memory, and disk size for the VMs created by this template.
|CPUs||Number of vCPUs allocated to the VM (cores)||2|
|Memory||Amount of RAM allocated to the VM (MB)||2 GB|
|Template Image||✓||Name of the Disk Image template to clone as the VM's primary disk (must support cloud-init)|
|VM Disk Size||New size of the VM's primary disk (in GiB)|
|Additional Disk Size||Size of an additional disk to add to the VM (in GiB)|
|Storage Container||Storage container UUID in which to provision an additional disk|
|Cloud Config YAML||Cloud-init to provide to the VM (will be patched with Rancher root user)|
|Network||✓||Name(s) of the network(s) to attach to the VM|
|VM Categories||Name(s) of any categories to be applied to the VM|
The node template allows a VM to be provisioned with multiple networks. In the Network field, you can click Add to add any networks available to you in AOS.
A category is a grouping of entities into a key value pair. Typically, VMs are assigned to a category based on some criteria. Policies can then be tied to those entities that are assigned (grouped by) a specific category value.
Cloud-init allows you to initialize your nodes by applying configuration on the first boot. This may involve things such as creating users or authorizing SSH keys.
To make use of cloud-init initialization, paste a cloud config using valid YAML syntax into the Cloud Config YAML field. Refer to the cloud-init documentation for a commented set of examples of supported cloud config directives.
Note that cloud-init based network configuration is not recommended and only supported via user data
runcmd rather than by NoCloud or other network configuration datasources.
Nutanix IP Address Management (IPAM) or another DHCP service is recommended.
In the Engine Options section of the node template, you can configure the container daemon. You may want to specify the container version or a container image registry mirror.
If you're provisioning Red Hat Enterprise Linux (RHEL) or CentOS nodes, leave the Docker Install URL field as the default value, or select none. This will bypass a check for Docker installation, as Docker is already installed on these node types.
If you set Docker Install URL to a value other than the default or none, you might see an error message such as the following:
Error creating machine: RHEL ssh command error: command: sudo -E yum install -y curl err: exit status 1 output: Updating Subscription Management repositories.
