This section explains how to deploy a compute node using an existing template
Edit me
Deploy a Compute Node with Default Template
The parameter DEFAULT_TEMPLATE defines the global default template to deploy compute nodes. If the node does not have a pre-defined template, it will use the global default version. The default template for a particular node can be defined by using the snow set node --template <template_name>. More information about how to setup per node basis templates available here.
snow deploy <compute_node(s)>
Deploy a Compute Node with a Specific Template
In order to deploy a compute node using a specific template, use the following command:
snow deploy <compute_node(s)> <template_name>
More information about that available in Template Overview
