Mapping of host URL with agent-grpc service

Follow the instruction below to map a host URL with agent-grpc service.

1. Get the load balancer IP of controller agent in the ISD installed namespace using the below command.

   kubectl get svc -n isd | grep agent-grpc

2. In this example the Load Balancer IP address is 34.172.225.153 Refer to the below output.

   $ kubectl get svc -n isd | grep agent-grpc
   agent-grpc                               LoadBalancer   10.68.9.229    34.172.225.153   9001:31016/TCP               2d21h

3. You need to map this Load Balancer IP to any of the DNS providers. Check the DNS entry using the nslookup command as shown below.

    nslookup isdcontroller.agent.opsmx.net

   Refer the below output

   Server:		127.0.0.53
   Address:	127.0.0.53#53
   Non-authoritative answer:
   Name:	isdcontroller.agent.opsmx.net
   Address: 34.172.225.153

4. Run the below command to edit the controller config map “opsmx-controller-controller1”.

   kubectl edit cm opsmx-controller-controller1  -n isd

   Replace the agentHostname and remoteCommandHostname in the config map under “data” section as mentioned below and save it.

   apiVersion: v1
   data:
     configFile: |
       serviceHostname: opsmx-controller-controller1
       agentHostname: isdcontroller.agent.opsmx.net
       remoteCommandHostname: isdcontroller.agent.opsmx.net
       controlHostname: opsmx-controller-controller1
       #agentAdvertisePort: "443"

5. Delete the controller pod using the below command.

   kubectl delete po -l app=opsmx-controller-controller1  -n isd

6. Now you are done with the Controller configuration. This DNS can be used while configuring the agent with Argo.
