Saikrishna 42ffa8df71 Auto-generate multus conf. Do not exit sriov DS
Instead of relying on configmap to be created/customized by the user to
generate multus conf, we autogenerate it using the current default CNI
conf file on the host. This way CNI's with host specific conf details
will continue to work.

```
{
  "type": "calico",
  "nodename": "clr-01",
   ...
}
```

Since SR-IOV device may not be present on all nodes, the daemonset
should not exit as this will put the pod in restart loop. This would
cause the kubelet and runtimes to repeatedly restart, as per
initContainer logic.

# Multi-Network
## Daemonset
We launch a `Daemonset` with an `initContainer` which sets up the CNI
directories on the host with the necessary binaries and configuration files.
> NOTE: SR-IOV devices are not necessary to test multi-network capability
### Customization
The device plugin will register the SR-IOV enabled devices on the host, specified as
`rootDevices` in [sriov-conf.yaml](sriov-conf.yaml). Helper [systemd unit](systemd/sriov.service)
file is provided, which enables SR-IOV for the above `rootDevices`
> NOTE: This assumes homogenous nodes in the cluster
### Pre-req (SR-IOV only)
One each SR-IOV node make sure `VT-d` is enabled in the BIOS and `intel_iommu=on` on kernel commandline.
Setup systemd to bring up VFs on designated interfaces bound to network driver or `vfio-pci`
```bash
# Make sure vfio-pci is loaded on boot
echo 'vfio-pci' | sudo tee /etc/modules-load.d/sriov.conf
sudo systemctl restart systemd-modules-load.service
sudo cp systemd/sriov.sh /usr/bin/sriov.sh
sudo cp systemd/sriov.service /etc/systemd/system/
sudo systemctl daemon-reload
sudo systemctl enable --now sriov.service
```
### Install
To install and configure `multus-cni` on all nodes, along with
`sriov-cni`, `vfioveth-cni` and `sriov-network-device-plugin`
```bash
kubectl apply -f .
kubectl get nodes -o json | jq '.items[].status.allocatable' # should list "intel.com/sriov_*"
```
## Tests
### Default only
To test if default connectivity is working
```bash
kubectl apply -f test/pod.yaml
kubectl exec test -- ip a # should see one interface only
```
### Bridge
To test multus with second interface created by `bridge` plugin
```bash
kubectl apply -f test/bridge
kubectl exec test-bridge -- ip a # should see two interfaces
ip a show mynet # bridge created on host if it doesnt exist already
```
### SR-IOV
To test multus with second interface created by `sriov` plugin
```bash
kubectl apply -f test/sriov
kubectl exec test-sriov -- ip a # second interface is a VF
kubectl exec test-sriov-dpdk -- ip a # veth pair with details of VF
kubectl exec test-sriov-dpdk -- ls -l /dev/vfio

# Kata Admission controller webhook
Implement a simple admission controller webhook to annotate pods with the
Kata runtime class.
## How to build the admission controller
First build the admission controller image and the associated
Kubernetes yaml files required to instantiate the admission
controller.
```bash
$ docker build -t katadocker/kata-webhook-example:latest .
$ ./create_certs.sh
```
> **Note:**
> Image needs to be published for the webhook needs to work. Alternately
> on a single machine cluster change the `imagePullPolicy` to use the locally
> built image.
## Making Kata the default runtime using an admission controller
Today in `crio.conf` `runc` is the default runtime when a user does not specify
`runtimeClass` in the pod spec. If you want to run a cluster where Kata is used
by default, except for workloads we know for sure will not work with Kata, use
the [admission webhook](https://kubernetes.io/docs/reference/access-authn-authz/extensible-admission-controllers/#admission-webhooks)
and sample admission controller we created by running
```bash
$ kubectl apply -f deploy/
```
The webhook mutates pods to use the kata runtime class for all pods except
those with
* `hostNetwork: true`
* namespace: `rook-ceph` and `rook-ceph-system`
