X-K8S leverages plugins for the better NFV performance in 5G use senario, like CMK (Cpu Manager for Kubernetes),
NFD (Node Feature Discovery), intel's userspace-cni-network-plugin, etc.
And based on the kubespray v2.12.1 as its deploy tool.

For the detail deploy instruction, check the kubespray's readme.

1. Python3
2. pip3

1. Disable and delete swap on all of your nodes.

2. If you want to enable sriov support on your kubernetes cluster.
   a. Create VF on all of your nodes.
   b. Create /etc/pcidp/config.json on each node base on your SRIOV NIC bus address.
   You can use lshw -class network -businfo to check the bus address of root device.
   For example, your config.json should look like...

   {
     "resourceList":
     [
       {
         "resourceName": "sriov_pool_a",
         "selectors": {
           "vendors": ["8086"],
           "pfNames" : ["enp4s0f0"]
         }
       },
       {
         "resourceName": "sriov_pool_b",
         "selectors": {
           "vendors": ["8086"],
           "pfNames" : ["enp129s0f0"]
         }
       }
     ]
   }

   Go check SRIOV manual for more information.

3. Enable root account and allow root remote login for each node.

4. Set password free login for root of deploy node on each node.

# at root of deploy node
ssh-copy-id <node1_ip>

On Deploy Node

1. Install requirement.

   cd x-k8s
   sudo pip3 install -r requirements.txt
   

2. Edit hosts.ini in /x-k8s/kubespray/inventory/mycluster/hosts.ini

3. Edit /x-k8s/kubespray/extraVars.yml to turn on the feature you want.
