add egress CRD

[backguynn]

Description based on K8s
To use Egress, you must first create the following LoadBalancer service.

apiVersion: v1
kind: Service
metadata:
  name: loxilb-egress-service
  namespace: kube-system
  annotations:
    loxilb.io/usepodnetwork: "yes"
spec:
  externalTrafficPolicy: Local
  type: LoadBalancer
  loadBalancerClass: loxilb.io/loxilb
  selector:
    app: loxilb-app
  ports:
  - name: loxilb-ha
    port: 2020
    targetPort: 8080
    protocol: TCP

And apply the egress CRD to K8s.

kubectl apply -f https://raw.githubusercontent.com/loxilb-io/kube-loxilb/refs/heads/main/manifest/crds/egress-crd.yaml

An example yaml file for creating egress is as follows.

apiVersion: "egress.loxilb.io/v1"
kind: Egress
metadata:
  name: test-egress
spec:
  #address: IP list of the Pod on which you want the egress rule applied
  addresses:        
  - 10.42.1.2/32
  - 10.42.0.5/32
  #vip: IP in addresses is SNATed to the corresponding VIP.
  vip: 172.18.0.254
