wshobson/linkerd-patterns

Linkerd 서비스 메시 패턴을 구현하여 경량화되고 보안에 중점을 둔 서비스 메시 배포를 지원합니다. Linkerd 설정, 트래픽 정책 구성, 최소 오버헤드로 제로 트러스트 네트워킹 구현 시 사용하세요.

linkerd-patterns란 무엇인가요?

이 스킬은 Linkerd 서비스 메시를 활용한 패턴들을 제공하여, 개발자와 운영 팀이 경량화된 서비스 메시를 손쉽게 배포하고 관리할 수 있도록 돕습니다. 주로 Kubernetes 환경에서 동작하며, Linkerd의 핵심 기능인 트래픽 분할, 재시도, 타임아웃, mTLS(상호 TLS) 인증, 접근 제어 정책 등을 구성하는 방법을 제시합니다. 특히 최소한의 리소스 오버헤드로 제로 트러스트 네트워킹을 구현하고자 할 때 유용하며, 다양한 배포 시나리오에서 빠르게 적용할 수 있는 실용적인 예제와 설정 코드를 포함합니다. 이 스킬은 Claude Code, Cursor, Codex 등 주요 AI 에이전트와 호환되며, 사용자는 자연어 명령으로 Linkerd 관련 작업을 자동화할 수 있습니다.

linkerd-patterns은(는) 무엇을 하나요?

Linkerd 서비스 메시 패턴을 구현하여 경량화되고 보안에 중점을 둔 서비스 메시 배포를 지원합니다. Linkerd 설정, 트래픽 정책 구성, 최소 오버헤드로 제로 트러스트 네트워킹 구현 시 사용하세요.

개요

이 스킬은 Linkerd 서비스 메시의 일반적인 패턴을 모아놓은 것으로, Kubernetes 환경에서 안전하고 효율적인 서비스 간 통신을 설정하는 데 도움을 줍니다. Linkerd는 CNCF(Cloud Native Computing Foundation)의 인큐베이팅 프로젝트로, 최소한의 성능 오버헤드로 서비스 메시 기능을 제공합니다.

주요 패턴

1. 트래픽 분할 (Traffic Split)

트래픽 분할을 통해 카나리 배포, A/B 테스트 등을 수행할 수 있습니다.

apiVersion: split.smi-spec.io/v1alpha2
kind: TrafficSplit
metadata:
  name: my-service-split
spec:
  service: my-service
  backends:
  - service: my-service-v1
    weight: 90
  - service: my-service-v2
    weight: 10

2. 재시도 및 타임아웃 (Retries and Timeouts)

일시적인 장애를 처리하기 위한 재시도와 응답 시간 제한을 설정합니다.

apiVersion: policy.linkerd.io/v1beta1
kind: Retry
metadata:
  name: my-retry
spec:
  routes:
  - name: my-route
    retry:
      budget:
        minRetriesPerSecond: 10
        percent: 0.2
      retryFor: |
        statusCode == 503
    timeout: 300ms

3. mTLS 및 인증 (mTLS and Authentication)

Linkerd는 기본적으로 mTLS를 활성화하여 서비스 간 통신을 암호화합니다.

apiVersion: policy.linkerd.io/v1beta1
kind: Server
metadata:
  name: my-server
  namespace: my-namespace
spec:
  podSelector:
    matchLabels:
      app: my-app
  port: 8080
  proxyProtocol: HTTP/1

4. 접근 제어 정책 (Access Control Policies)

메시 내 서비스 간 접근을 세밀하게 제어합니다.

apiVersion: policy.linkerd.io/v1beta1
kind: AuthorizationPolicy
metadata:
  name: my-policy
spec:
  targetRef:
    group: policy.linkerd.io
    kind: Server
    name: my-server
  requiredAuthenticationRef:
    group: policy.linkerd.io
    kind: MeshTLSAuthentication
    name: my-auth

사용 방법

  1. Linkerd가 설치된 Kubernetes 클러스터가 필요합니다.
  2. 원하는 패턴의 YAML 매니페스트를 적용합니다.
  3. linkerd check 명령어로 설정을 검증합니다.
# Linkerd 설치 확인
linkerd check --pre

# 메시에 네임스페이스 추가
kubectl annotate namespace my-namespace linkerd.io/inject=enabled

# 패턴 적용
kubectl apply -f my-pattern.yaml
