62-Configure the K3s “DHCP” LoadBalancer service

Prerequisite: Already provision K3s cluster and cloud provider on test plan

• 59-Create K3s Kubernetes Cluster
• 61-Deploy Harvester cloud provider to k3s Cluster

Create Nginx workload for testing

1. Create a test-nginx deployment with image nginx:latest.
2. Add pod label test: test.

Create a DHCP LoadBalancer

1. Open Kubectl shell.
2. Create test-dhcp-lb.yaml file.

   apiVersion: v1
   kind: Service
   metadata:
       annotations:
       cloudprovider.harvesterhci.io/ipam: dhcp
       name: test-dhcp-lb
       namespace: default
   spec:
       ports:
       - name: http
       nodePort: 30172
       port: 8080
       protocol: TCP
       targetPort: 80
       selector:
       test: test
       sessionAffinity: None
       type: LoadBalancer
   

3. Run k apply -f test-dhcp-lb.yaml to apply it.
4. The Pool LoadBalancer should get an IP from vip-pool and work.

Expected Results

1. Can create load balance service correctly
2. Can route workload to nginx deployment
