kubectl版本：

Client Version: version.Info{Major:"1", Minor:"9", GitVersion:"v1.9.5", GitCommit:"f01a2bf98249a4db383560443a59bed0c13575df", GitTreeState:"clean", BuildDate:"2018-03-19T15:59:24Z", GoVersion:"go1.9.3", Compiler:"gc", Platform:"linux/amd64"}
Server Version: version.Info{Major:"1", Minor:"9", GitVersion:"v1.9.0", GitCommit:"925c127ec6b946659ad0fd596fa959be43f0cc05", GitTreeState:"clean", BuildDate:"2017-12-15T20:55:30Z", GoVersion:"go1.9.2", Compiler:"gc", Platform:"linux/amd64"}

gitlab版本： 10.6-ce

gitlab runner image： gitlab / gitlab-runner：alpine-v10.3.0

我只是将一个kubernetes集群（不是GKE，只是我自己部署的k8s集群）集成到gitlab项目中，然后安装了一个gitlab-runner。

所有这一切，都是Adding an existing Kubernetes cluster。

之后，我添加了.gitlab-ci.yml一个阶段，并将其推送到了回购。这是内容：

build-img:
  stage: docker-build
  script:
#    - docker build -t $CONTAINER_RELEASE_IMAGE .
#    - docker tag $CONTAINER_RELEASE_IMAGE $CONTAINER_LATEST_IMAGE
#    - docker push $CONTAINER_IMAGE
    - env | grep KUBE
    - kubectl --help
  tags:
    - kubernetes
  only:
    - develop

然后我明白了：

$ env | grep KUBE
KUBERNETES_PORT_443_TCP_PORT=443
KUBERNETES_PORT=tcp://10.96.0.1:443
KUBERNETES_SERVICE_PORT=443
KUBERNETES_SERVICE_HOST=10.96.0.1
KUBERNETES_PORT_443_TCP_PROTO=tcp
KUBERNETES_SERVICE_PORT_HTTPS=443
KUBERNETES_PORT_443_TCP_ADDR=10.96.0.1
KUBERNETES_PORT_443_TCP=tcp://10.96.0.1:443
$ kubectl --help
/bin/bash: line 62: kubectl: command not found
ERROR: Job failed: error executing remote command: command terminated with non-zero exit code: Error executing in Docker Container: 1

kubectl尚未安装在跑步者中，并且找不到KUBE_TOKEN，KUBE_CA_PEM_FILE或KUBECONFIG等一些环境变量（请参阅Deployment variables }）。

搜索了gitlab的官方文档，什么都没有。

那么，我如何通过这个跑步者部署项目？

Answer 1

gitlab-runner没有内置命令，它旋转具有预定义图像的容器，然后从该容器中的脚本远程执行命令。

您尚未定义图片，因此将使用gitlab-runner设置中定义的默认图片。

所以，您可以先在script:或before_script:

中使用Install kubectl binary using curl

build-img:
  stage: docker-build
  before_script:
   - curl -LO https://storage.googleapis.com/kubernetes-release/release/$(curl -s https://storage.googleapis.com/kubernetes-release/release/stable.txt)/bin/linux/amd64/kubectl 
   - chmod +x ./kubectl
  script:
   - ...
   - ./kubectl --version

或使用带有kubectl的映像创建单独的部署阶段，例如roffe/kubectl：

stages:
- docker-build
- deploy

build-img:
  stage: docker-build
  script:
   - docker build -t $CONTAINER_RELEASE_IMAGE .
   - docker tag $CONTAINER_RELEASE_IMAGE $CONTAINER_LATEST_IMAGE
   - docker push $CONTAINER_IMAGE
  tags:
   - kubernetes

deploy:dev:
  stage: deploy 
  image: roffe/kubectl
  script:
   - kubectl .....
  tags:
   - kubernetes

如何通过k8s gitlab-ci转轮将内容部署到k8s集群？
