안녕하세요. AWS Blueprints Hands On 내용을 공유하기 위해 작성한 글입니다.

참고 : https://catalog.workshops.aws/eks-blueprints-for-cdk/en-US

1. Create multiple EKS clusters using Pipelines

2. Implement Blueprints add-ons

3. Deploy your teams’ workloads

GitOps를 쓰는 이유

개발자에게 익숙한 절차
빠른 복구와 자동화
여러 배포 모드 작동 가능
확장성 및 안정성
실행 중인 환경에서 애플리케이션 분리됨

ArgoCD

Argo CD is a declarative, GitOps continuous delivery tool for Kubernetes. The Argo CD add-on provisions ArgoCD into an EKS cluster, and can optionally bootstrap your workloads from public and private Git repositories.

Configure and Deploy EKS Clusters

// lib/pipeline.ts
import * as cdk from 'aws-cdk-lib';
import { Construct } from 'constructs';
import * as blueprints from '@aws-quickstart/eks-blueprints';
import * as cpactions from 'aws-cdk-lib/aws-codepipeline-actions';import { TeamPlatform, TeamApplication } from '../teams'; // HERE WE IMPORT TEAMSexport default class PipelineConstruct extends Construct {
  constructor(scope: Construct, id: string, props?: cdk.StackProps){
    super(scope, id)const account = props?.env?.account!;
    const region = props?.env?.region!;
    
    const blueprint = blueprints.EksBlueprint.builder()
    .account(account)
    .region(region)
    .addOns(
      new blueprints.ClusterAutoScalerAddOn,
      new blueprints.ArgoCDAddOn
      )
    .teams(new TeamPlatform(account), new TeamApplication('burnham',account)); // HERE WE ADD THE TEAMS
  
    blueprints.CodePipelineStack.builder()
      .name("eks-blueprints-workshop-pipeline")
      .codeBuildPolicies(blueprints.DEFAULT_BUILD_POLICIES)
      .repository({
          codeCommitRepoName: 'my-eks-blueprints-pipeline',
          targetRevision: 'main',
          codeCommitOptions:{
            trigger: cpactions.CodeCommitTrigger.EVENTS
          }
      })
      // WE ADD THE STAGES IN WAVE FROM THE PREVIOUS CODE
      .wave({
        id: "envs",
        stages: [
          { id: "dev", stackBuilder: blueprint.clone('us-west-2')},
          { id: "test", stackBuilder: blueprint.clone('us-east-2')},
          { id: "prod", stackBuilder: blueprint.clone('us-east-1')}
        ]
      })
      .build(scope, id+'-stack', props);
 }
}

//new blueprints.ArgoCDAddOn 추가

// lib/pipeline.ts
.addOns(
      new blueprints.ClusterAutoScalerAddOn,
      new blueprints.ArgoCDAddOn
      )

kubectl update

aws eks update-kubeconfig — region us-west-2 — name dev-blueprint — role-arn <arn:aws:iam::XXXXXXXXXXX>

Manage workloads on ArgoCD

Expose argocd-server

kubectl patch svc blueprints-addon-argocd-server -n argocd -p '{"spec": {"type": "LoadBalancer"}}'export ARGOCD_SERVER=`kubectl get svc blueprints-addon-argocd-server -n argocd -o json | jq --raw-output '.status.loadBalancer.ingress[0].hostname'`kubectl get svc -n argocd
