-To create a new image containing the customizations:
-
-Edit `packer/custom.json` to increment the tag, then run this script (needs
-[Packer](https://www.packer.io/) in your path)
-
-```
-./script/build_customizations_image

-
-Then edit `kubernetes/gitea-server.yaml` to use the new tag

-# HTTP(S) load balancing with Ingress
-
-## Resources
-
-Features of GKE Ingress from the Google Cloud docs:
-https://cloud.google.com/kubernetes-engine/docs/concepts/ingress
-
-It does hostname-aware HTTP(S) load balancing, and is billed like a regular
-Load Balancer (https://cloud.google.com/compute/pricing#lb). The advantages are
-that we can use one set of firewall rules (ports 80 and 443) for multiple
-services, and easy Let's Encrypt certificates for services with no built-in
-support for it
-
-This 3 part article was a good resource:

-
-I couldn't find information about setting
-`ingress.kubernetes.io/rewrite-target` to `/` anywhere else, without it only 
-`/` worked on an host, all other URLs would go to the default backend and
-return a 404.

-## cert-manager
-
-### Create the cert-manager resources
-
-cert-manager provides a Let's Encrypt certificate issuer, and lets you mount it
-in an Ingress resource, making it possible to use HTTP ACME challenges
-
-Get the reserved IP you created in the first step:
-
-    $ gcloud compute addresses list --global
-    NAME        ADDRESS/RANGE   TYPE      PURPOSE  NETWORK  REGION  SUBNET  STATUS
-    ingress-ip  35.244.164.133  EXTERNAL                                    IN_USE
-
-Set the DNS record for the domain you want a Let's Encrypt cert for to this IP.
-
-Now it's time to create the cert-manager
-
-https://docs.cert-manager.io/en/release-0.8/getting-started/install/kubernetes.html
-
-    kubectl create namespace cert-manager
-
-    kubectl apply -f https://github.com/jetstack/cert-manager/releases/download/v0.8.1/cert-manager.yaml --validate=false
-
-I had to run the apply command twice for it to create all the resources. On the
-first run I got these errors. Running it a second time successfully created all
-the resources
-
-    unable to recognize "cert-manager.yaml": no matches for kind "Issuer" in version "certmanager.k8s.io/v1alpha1"
-    unable to recognize "cert-manager.yaml": no matches for kind "Certificate" in version "certmanager.k8s.io/v1alpha1"
-    unable to recognize "cert-manager.yaml": no matches for kind "Issuer" in version "certmanager.k8s.io/v1alpha1"
-    unable to recognize "cert-manager.yaml": no matches for kind "Certificate" in version "certmanager.k8s.io/v1alpha1"
-
-We name the ingress explicitely so it only runs on one. Having only one IP to
-set on the DNS records makes the HTTP validation easier. Using the class would
-attach the validation endpoint to all Ingresses of that class

-## Add another service
-
-To add another service behind the Ingress, you set the DNS entry for its domain
-to the Ingress IP, deploy your service, create a NodePort to expose it, and
-finally add its host to the Ingress config (both tls and rules, see example
-above)
