You can customize a CNF's infrastructure according to its unique requirements. Customizing the infrastructure requirements enables you to create a cluster, customize, and deploy the network functions without any manual user inputs.
Network functions from different vendors have their own unique set of infrastructure requirements. Defining these requirements in the network functions ensure that they are instantiated and deployed in a cluster without you having to log in to their master or worker nodes.
To customize the cluster according to network function requirements, you must add the requirements in the network function catalog. Go to Network Functions > Catalogs tab. Click the network function that requires a customization and select the Source tab.
infra_requirementsto the TOSCA. In this extension you can define the node, Containers as a Service (CaaS), and Platform as a Service (PaaS) components:
node_components, you can define the requirements for the node. These requirements include kernel type, kernel version, kernel arguments, required packages, tuned configuration. You can also define additional networks to be configured for worker node. All the changes are applied on the worker nodes of the nodepool.
caas_components, define the CaaS components such as CNIs to be installed on each worker node. At presents, supports SRIOV.
infra_requirementsin the CNF catalog, the nodepool is customized according to the differences detected between the CNF catalog and the actual configuration present in the nodepool during instantiation.
