eks-app-helm-chart: Deploying Applications on Amazon EKS with Helm
This document provides the configuration details for the eks-app-helm-chart.
The chart creates a deployment, a service, a pod disruption budget, an ingress resource, and HPA.
Amazon EKS Auto Mode
If you are using EKS Auto Mode this chart is application ready. You can deploy the chart as is, and it will create the necessary resources for you.
- IngressClass Controller:
eks.amazonaws.com/albby default, if you are using a different ingress controller, you can change theingressClass.controllervalue. - Ingress Annotations: since the default IngressClass Controller is
eks.amazonaws.com/alb, the default annotations are set toalb.ingress.kubernetes.io/target-type: ipandalb.ingress.kubernetes.io/scheme: internet-facing. If you are using a different ingress controller, you can change theingress.annotationsvalue.- More information on the annotations can be found here.
