[Bitbucket Pipeline] Design bitbucket-pipeline and eksctl to upgrade EKS cluster

Hello các bạn mình đã có 1 bài upgrade eks bằng eksctl.

[EKS] Upgrade eks cluster by eksctl

Sau khi chúng ta đã understanded các command thì design bitbucket-pipeline để upgrade eks cluster.

Đầu tiền bạn cần set up các env chung.

eks-upgrade

AWS_ACCESS_KEY_ID: xxxx
AWS_SECRET_ACCESS_KEY: xxxx
regionName: us-west-2
eksClusterName: xxxx

Và đây là file bitbucket-pipelines.yml

pipelines:
  custom:
    ### Running eksctl
    ### Create eksClusterName, regionName in Deployment ENV
    upgrade-eks:
      - variables:
          - name: upgradeToVersion
            default: '1.20'  
            allowed-values:         # optionally restrict variable values
              - '1.20'
              - '1.21'
      - step:
          name: 'Set environment variables'
          deployment: eks-upgrade
          image: weaveworks/eksctl:latest
          script:
            - printenv | xargs echo export > .envs
          artifacts:
            - .envs
      - step:
          name: 'Get Cluster infomations'
          image: weaveworks/eksctl:latest
          script:
            - source .envs
            - eksctl get cluster --name $eksClusterName --region $regionName --output yaml
      - step:
          name: 'Upgrade EKS Controller'
          image: weaveworks/eksctl:latest
          trigger: manual
          script:
            - source .envs
            - eksctl upgrade cluster --name $eksClusterName --region $regionName  --version $upgradeToVersion --approve
      - step:
          name: 'Create New Node Group'
          image: weaveworks/eksctl:latest
          trigger: manual
          script:
            - source .envs
            - eksctl create nodegroup --cluster $eksClusterName --region $regionName

    run-kubectl-command:
      - variables:
          - name: namespace
            default: 'default'  
            allowed-values:
              - 'default'
              - 'kube-system'
          - name: command
            default: 'get node'
      - step:
           name: "Run kubectl command"
           deployment: eks-upgrade
           image: bitbucketpipelines/aws-eks-kubectl-run:latest
           script:
             - aws eks --region $regionName update-kubeconfig --name $eksClusterName
             - echo "run command --> kubectl -n $namespace $command"
             - kubectl -n $namespace $command

    get-nodegroup-eks:
      - step:
          name: "Get Node Group EKS"
          deployment: eks-upgrade
          image: weaveworks/eksctl:latest
          script:
            - eksctl get nodegroup --cluster $eksClusterName --region $regionName

    delete-nodegroup-eks:
      - variables:
          - name: nodeGroupName
      - step:
          name: "Delete Node Group EKS"
          deployment: eks-upgrade
          image: weaveworks/eksctl:latest
          script:
            - eksctl delete nodegroup --cluster $eksClusterName --region $regionName --name $nodeGroupName

Sau khi deploy hết thì bạn cần kiểm tra lại các ingress có hoạt động ko nhé.
