如何獲取基於 AWS kops 的 kubernetes 集群 IP 地址以連接 gitlab CICD 管道

Question

我正在嘗試創建基本的 gitlab CICD 管道，它將基於 node.js 的后端部署到基於 AWS kops 的 k8s 集群。為此，我創建了gitlab-ci.yml文件，該文件將用於部署整個 CICD 管道，但是我對如何部署感到困惑to get kubernetes cluster IP address so I can use it in gitlab-ci.yml to set as - kubectl config set-cluster k8s --server="$CLUSTER_ADDRESS" where I want CLUSTER_ADDRESS to configure with gitlab in gitlab-ci.yml.

任何幫助，將不勝感激。

variables:
  DOCKER_DRIVER: overlay2
  REGISTRY: $CI_REGISTRY
  IMAGE_TAG: $CI_REGISTRY_IMAGE
  K8S_DEPLOYMENT_NAME: deployment/$CI_PROJECT_NAME
  CONTAINER_NAME: $CI_PROJECT_NAME

stages:
  - build
  - build-docker
  - deploy


build-docker:
  image: docker:latest
  stage: build-docker
  services:
    - docker:dind
  tags:
    - privileged
  only:
    - Test
  script:
    script:
    - docker login -u gitlab-ci-token -p $CI_BUILD_TOKEN $REGISTRY
    - docker build --network host -t $IMAGE_NAME:$IMAGE_TAG -t $IMAGE_NAME:latest .
    - docker push $IMAGE_NAME:$IMAGE_TAG
    - docker push $IMAGE_NAME:latest
deploy-k8s-(stage):
  image:
    name: kubectl:latest
    entrypoint: [""]
  stage: deploy
  tags:
    - privileged
  # Optional: Manual gate

  dependencies:
    - build-docker
  script:
    - kubectl config set-cluster k8s --server="$CLUSTER_ADDRESS"
    - kubectl config set clusters.k8s.certificate-authority-data $CA_AUTH_DATA
    - kubectl config set-credentials gitlab-service-account --token=$K8S_TOKEN
    - kubectl config set-context default --cluster=k8s --user=gitlab-service-account --namespace=default
    - kubectl config use-context default
    - kubectl set image $K8S_DEPLOYMENT_NAME $CI_PROJECT_NAME=$IMAGE_TAG
    - kubectl rollout restart $K8S_DEPLOYMENT_NAME

如果您當前的 kubeconfig 上下文設置為相關集群，您可以運行以下命令來獲取所需的集群地址：

kubectl config view --minify --raw \
    --output 'jsonpath={.clusters[0].cluster.server}'

如果沒有，您可以添加--context <cluster name> 。

在大多數情況下，這將是https://api.<cluster name> 。
