Ingress and networking

Add an ingress Helm Chart to an application
Find the Helm Chart provided by ReleaseHub for generating an ingress for your application in our GitHub repository.
You can either copy the contents of the ReleaseHub helm-ingress repository into your source control repository or reference the Helm chart using a remote repository chart:
charts:
- name: <service>-ingress
  add: release-ingress
  repo_url: https://raw.githubusercontent.com/releasehub-com/helm-ingress/main/
  directory: <path in your repo to values.yaml>
  install: release-ingress/release-ingress
  values: values.yaml
Configure the ingress Helm Chart values
You need a values.yaml file in your source control repository to use the Helm Chart.
Customize the values.yaml file to reference the service you would like to expose to the Internet. For example, here is a values.yaml file for a service named frontend:
service:
  name: frontend
  externalPort: 5000
ingress:
  hosts:
    - ${FRONTEND_INGRESS_HOST}
  annotations:
    kubernetes.io/ingress.class: nginx
    nginx.ingress.kubernetes.io/force-ssl-redirect: "true"
Important version information
If you are using a Kubernetes cluster on v1.20 or below, add the following to your chart's definition to pin the version to an older chart:
charts:
- name: <service>-ingress
  version: 2.1.0
  ...
Add a load balancer to a chart
If you are using AWS with EKS, include the following annotations to your service to create a Network Load Balancer (NLB) and assign an external DNS name. This example configures a TLS-enabled LDAPS port (636) and non-TLS LDAP port (389):
apiVersion: v1
kind: Service
metadata:
  name: fid-service
  annotations:
    service.beta.kubernetes.io/aws-load-balancer-type: external                                              # This creates an NLB
    service.beta.kubernetes.io/aws-load-balancer-nlb-target-type: ip                                         # Do not touch
    service.beta.kubernetes.io/aws-load-balancer-scheme: internet-facing                                     # Or, "private"
    service.beta.kubernetes.io/aws-load-balancer-cross-zone-load-balancing-enabled: "true"                   # Recommended
    service.beta.kubernetes.io/aws-load-balancer-ssl-cert: <fill in your ACM certificate here>               # Optional for using TLS
    service.beta.kubernetes.io/aws-load-balancer-ssl-ports: "636"                                            # Optional for using TLS
    service.beta.kubernetes.io/aws-load-balancer-ssl-negotiation-policy: ELBSecurityPolicy-TLS13-1-2-2021-06 # Optional for using TLS
    external-dns.alpha.kubernetes.io/hostname: <fill in the hostname to use with a values file or similar>
