✅ Kind(Kubernetes in Docker)

  • Docker 컨테이너 안에 쿠버네티스 클러스터를 실행할 수 있게 해주는 오픈소스 도구

1. Docker 컨테이너를 노드로 사용

  • Kubernetes 클러스터의 각 노드(Node) 는 실제 VM이나 서버 대신, 도커 컨테이너로 만들어집니다.
  • Kind는 이 노드 컨테이너들을 자동으로 생성하고 설정해줍니다.

2. 클러스터 구성

  • Kind는 컨트롤 플레인(Control Plane) 과 워커 노드(Worker Node) 를 도커 컨테이너로 구분하여 클러스터를 구성합니다.
    • 📦 kind-control-plane: Kubernetes API 서버, 스케줄러 등 포함
    • 📦 kind-worker, kind-worker2: 실제 애플리케이션이 배포되는 노드

✅ WSL2

  • Windows 안에서 리눅스를 실행할 수 있게 해주는 기능

🔧 WSL2의 특징

🧠 진짜 리눅스 커널 사용 WSL1보다 성능과 호환성이 좋아요
📂 윈도우 ↔ 리눅스 파일 공유 드래그&드롭, 복사/붙여넣기 가능
🐳 Docker 사용 가능 WSL2 위에서 Docker 실행이 가능해요
⚡ 빠른 부팅 가상머신보다 훨씬 빠르게 시작돼요

✅ 실습환경

  • WSL2 (Ubuntu) 에 Docker 설치
ssoon@DESKTOP-UQRJB87:~$ curl -fsSL https://get.docker.com -o get-docker.sh

ssoon@DESKTOP-UQRJB87:~$ sudo systemctl stop apparmor && sudo systemctl disable apparmor
  • Ubuntu 시스템에서 몇 가지 유용한 도구를 설치
    • bridge-utils: 네트워크 브릿지(네트워크 연결 관리)를 설정하는 도구.
    • net-tools: 네트워크 상태 확인(ifconfig, netstat 등) 도구.
    • jq: JSON 데이터를 보기 편하게 처리하는 도구.
    • tree: 폴더 구조를 트리 모양으로 보여주는 도구.
    • unzip: 압축 파일(.zip)을 푸는 도구.
    • kubectx: Kubernetes 클러스터 간 전환을 쉽게 해주는 도구.
    • kubecolor: Kubernetes 명령어(kubectl) 결과를 색깔로 보기 좋게 보여줘
