Kubernetes 실습 및 서비스 구축

윈도우 wsl2 ubuntu와 docker 연동

kind 설치

root@DESKTOP-Q4VBHGG:/home/yellownyou# curl -Lo ./kind https://github.com/kubernetes-sigs/kind/releases/download/v0.10.0/kind-linux-amd64
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current

전역에서 사용 할 수 있도록 위치를 이동

root@DESKTOP-Q4VBHGG:/home/yellownyou# mv ./kind /usr/local/bin/

vscode를 통한 wsl 원격 접속

하단 버튼을 클릭 후 ubuntu 고르

노드 설정 kind-node.yaml

kind: Cluster
apiVersion: kind.x-k8s.io/v1alpha4
nodes:
  - role: control-plane
  - role: worker
  - role: worker
  - role: worker

 

클러스터 생성

root@DESKTOP-Q4VBHGG:/home/yellownyou# kind create cluster --name kubernetes --config ./kind-node.yaml
Creating cluster "kubernetes" ...
 ✓ Ensuring node image (kindest/node:v1.20.2) 🖼
 ✓ Preparing nodes 📦 📦 📦 📦
 ✓ Writing configuration 📜
 ✓ Starting control-plane 🕹️
 ✓ Installing CNI 🔌
 ✓ Installing StorageClass 💾
 ✓ Joining worker nodes 🚜
Set kubectl context to "kind-kubernetes"
You can now use your cluster with:

kubectl cluster-info --context kind-kubernetes
