<p>I am using Google Kubernetes Engine and have the Google HTTPS Load Balancer as my ingress.</p>

<p>Right now the load balancer uses Let's Encrypt certificates. However, is there a simple way to ensure that the certificates are automatically renewed prior to their 90 day expiry?</p>

<p>You have not specified how you configured Let's Encrypt for your load balancer. Right now Google does not offer this for you, so I assume you mean you set the Let's Encrypt certificate yourself. In this case, Google can't renew your certificate.</p>

<p>Until there's an official support you can install a third-party add-on like <code>cert-manager</code> to automate certificate configuration and renewal. There's a GKE tutorial for doing this at <a href="https://github.com/ahmetb/gke-letsencrypt" rel="nofollow noreferrer">https://github.com/ahmetb/gke-letsencrypt</a>.</p>
