[k8s] Pods 구성 및 도메인 연동 실습

문제

wordpress 이미지를 3개의 파드로 구성된 디플로이먼트로 생성하시오. 이후 해당 파드의 내용물이 https://mydomain.click/wp 라는 URL로 외부에 출력되도록 만드시오.

 

 

1. NameSpace 생성

kubectl create namespace wordpress

 

2. Ingress Controller 설치

외부 요청을 클러스터 내부의 여러 서비스로 "경로 기반' "호스트기반"으로 라우팅 하기 위해 설치

helm upgrade --install ingress-nginx ingress-nginx --repo https://kubernetes.github.io/ingress-nginx --namespace ingress-nginx --create-namespace --set controller.admissionWebhooks.enabled=false

 

3. Deployment, Ingress, Service 생성

 

yaml 구성
