개요

• nginx ingress controller 설치방법을 설명합니다.

helm 저장소 추가

helm repo add ingress-nginx https://kubernetes.github.io/ingress-nginx
helm repo update

설치

• infra namespace에 설치했습니다.

metallb설치가 필요합니다.

kubectl create ns infra
helm install -n infra nginx-ingress ingress-nginx/ingress-nginx

ingress 리소스 생성방법

• ingress v1버전 이후에서는 ingressClassName필드가 꼭 필요합니다. 없으면 404 Not Found에러가 발생합니다.
