Fast Forward

If you have already assigned an FQDN to your load balancer, expand this box to fast-forward.

1. Proceed to the Verify section.

What You’ll Need

• A configured management environment.
• Your clone of the Arrikto GitOps repository.
• A working NGINX Ingress Controller deployment.

Procedure

1. Go to your GitOps repository, inside your rok-tools management environment:

   

   root@rok-toos:~/# cd ~/ops/deployments

2. Specify the FQDN to use for EKF:

   

   root@rok-tools:~/ops/deployments# export FQDN=<FQDN>

   Replace <FQDN> with your FQDN. For example:

   

   root@rok-tools:~/ops/deployments# export FQDN=ekf.example.com

3. Obtain the IP address of your Load Balancer and print its value:

   

   root@rok-tools:~# export ADDRESS=$(kubectl get services -n ingress-nginx ingress-nginx \ > -o jsonpath={.status.loadBalancer.ingress[].ip}) && echo ${ADDRESS?} 10.0.0.1

4. Create a DNS record in your nameservers, so that your FQDN resolves to the IP address of your Load Balancer.

Verify

1. Verify that your FQDN resolves to the IP of your Load Balancer:

   

   root@rok-tools:~/ops/deployments# host ${FQDN?} 10.0.0.1

Summary

You have successfully assigned an FQDN to your Load Balancer.
