 - 클러스터 : kubernetes-admin@kubernetes

 - 새로운 네임스페이스 생성 및 네임스페이스에 포드 생성

  . namespace name : ecommerce

  . pod Name : eshop-main

  . image : nginx:1.17

  . env : DB=mysql

# kubectl config use-context kubernetes-admin@kubernetes 
Switched to context "kubernetes-admin@kubernetes".

# kubectl create namespace ecommerce
namespace/ecommerce created

# kubectl get namespaces
NAME              STATUS   AGE

ecommerce         Active   6s
kube-node-lease   Active   100d
kube-public       Active   100d
kube-system       Active   100d

# kubectl run eshop-main --image=nginx:1.17 --env=DB=mysql --dry-run=client
pod/eshop-main created (dry run)

# kubectl run eshop-main --image=nginx:1.17 --env=DB=mysql --namespace ecommerce --dry-run=client -o yaml
apiVersion: v1
kind: Pod
metadata:
  creationTimestamp: null
  labels:
    run: eshop-main
  name: eshop-main
  namespace: ecommerce
spec:
  containers:
  - env:
    - name: DB
      value: mysql
    image: nginx:1.17
    name: eshop-main
    resources: {}
  dnsPolicy: ClusterFirst
  restartPolicy: Always
status: {}

# kubectl run eshop-main --image=nginx:1.17 --env=DB=mysql --namespace ecommerce
pod/eshop-main created

# kubectl get pod --namespace ecommerce 
NAME         READY   STATUS    RESTARTS   AGE
eshop-main   1/1     Running   0          8m23s

※ pod 생성하기 전에 --dry-run=client 넣어서 잘 실행되는지와 yaml 형식으로도 이상없는지 확인
