[Udemy] Pod 생성 및 삭제

Pod 생성

 

# AKS 생성

 

Portal에서 AKS 클러스터 생성

 

AKS를 생성하게 되면, 이에 필요한 인프라 리소스들도 자동으로 생성된다.

차근차근히 알아가보자!

 

# AKS 클러스터에 대한 Kubernetes 구성 파일(kubeconfig)을 설정

# az login
az login

# Configure Cluster Creds (kube config) for Azure AKS Clusters
az aks get-credentials --resource-group aks-rg1 --name aksdemo1

# Get Worker Node Status
kubectl get nodes
---
NAME                                STATUS   ROLES    AGE   VERSION
aks-agentpool-29221675-vmss000000   Ready    <none>   18m   v1.30.7
aks-agentpool-29221675-vmss000001   Ready    <none>   18m   v1.30.7

# Get Worker Node Status with wide option
kubectl get nodes -o wide

 

# Pod 생성

# Template
kubectl run <desired-pod-name> --image <Container-Image> 

# Replace Pod Name, Container Image
kubectl run my-first-pod --image stacksimplify/kubenginx:1.0.0

 

# Pod 확인

# List Pods
kubectl get pods

# Alias name for pods is po
kubectl get po

# List Pods with wide option
kubectl get pods -o wide

# describe 명령어로 더 구체적으로 pod 확인

kubectl describe pod my-first-pod

외부에서 Pod 내 애플리케이션에 접근하기 위해서, Nodeport 또는 Load Balancer가 필요한데

다음 시간에 적용해보기로 하고 Pod를 삭제해보자

 

# Pod 삭제

# To get list of pod names
kubectl get pods

# Delete Pod
kubectl delete pod <Pod-Name>
kubectl delete pod my-first-pod
