1️⃣ 준비

Nginx 차트 다운로드

helm repo add bitnami https://charts.bitnami.com/bitnami
helm repo update

helm pull oci://registry-1.docker.io/bitnamicharts/nginx --untar

Pulled: registry-1.docker.io/bitnamicharts/nginx:20.0.7

Error: failed to untar: a file or directory with the name nginx already exists

2️⃣ 설정

Nginx 사용자 Values 파일 생성

cp values.yaml dev-nginx-values.yaml

• prd-values.yaml 파일 편집
• 아래 내용 남기고 삭제

3️⃣ 설치

Nginx 설치 (standalone)

cd nginx
helm install my-nginx . -n my-dev --create-namespace -f dev-nginx-values.yaml

NAME: my-nginx
LAST DEPLOYED: Sun Jun  8 14:10:34 2025
NAMESPACE: my-dev
STATUS: deployed
REVISION: 1
TEST SUITE: None
NOTES:
CHART NAME: nginx

Did you know there are enterprise versions of the Bitnami catalog? For enhanced secure software supply chain features, unlimited pulls from Docker, LTS support, or application customization, see Bitnami Premium or Tanzu Application Catalog. See https://www.arrow.com/globalecs/na/vendors/bitnami for more information.

** Please be patient while the chart is being deployed **
NGINX can be accessed through the following DNS name from within your cluster:

    my-nginx.my-dev.svc.cluster.local (port 80)

To access NGINX from outside the cluster, follow the steps below:

1. Get the NGINX URL by running these commands:

    export NODE_PORT=$(kubectl get --namespace my-dev -o jsonpath="{.spec.ports[0].nodePort}" services my-nginx)
    export NODE_IP=$(kubectl get nodes --namespace my-dev -o jsonpath="{.items[0].status.addresses[0].address}")
    echo "http://${NODE_IP}:${NODE_PORT}"

WARNING: There are "resources" sections in the chart not set. Using "resourcesPreset" is not recommended for production. For production installations, please set the following values according to your workload needs:
  - cloneStaticSiteFromGit.gitSync.resources
+info https://kubernetes.io/docs/concepts/configuration/manage-resources-containers/

Nginx POD 확인

kubectl get pods -n my-dev -l app.kubernetes.io/instance=my-nginx

NAME                        READY   STATUS    RESTARTS   AGE
my-nginx-6587b665d8-cltx9   1/1     Running   0          4m46s

Nginx 차트 버전

helm ls -n my-dev

NAME            NAMESPACE       REVISION        UPDATED                                 STATUS

4️⃣ 검증

Nginx 서비스 포트 확인

kubectl get svc -l app.kubernetes.io/instance=my-nginx -n my-dev

NAME       TYPE       CLUSTER-IP     EXTERNAL-IP   PORT(S)                      AGE

Nginx 콘솔 접속

참고

자주 쓰는 명령어

# helm 삭제 후 재 생성
helm delete my-nginx -n my-dev
helm install my-nginx . -n my-dev -f dev-nginx-values.yaml --create-namespace
