 ### Conclusion
 
 By this stage you should have three Pi 4 B's running with Ubuntu 22.04.4 LTS each configured for SSH with a password or preferably a SSH private key and public key. Stay tuned for part 2 where we will dive into DHCP, NextDNS, NFS and install MicroK8s.

+### Conclusion
 
 By this stage you should have three Pi's each with MicroK8s, NFS CSI Driver, Cert Manager, Traefik, Ortelius and a NFS server up and running with Gimlet as the UI to Fluxcd which is all part of the management of our GitOps environment. Stay tuned for Part 4 where we unleash Cloudflare, LetsEncrypt with Traefik for automatic certificate renewal to provide secure services behind a single entrypoint.

-***FYI make sure you backup your persistent volumes on the NFS server***.
+### Conclusion
 
 In Part 4 we configured a certificate for our domain using Cloudflare, LetsEncrypt and Traefik. From my experience the crucial configuration change for any workloads to access the frontend securely was to enable the `ingress`, `TLS` and to change the `ingressClassName` to `traefik` in the Helm Release values.
