【问题描述】：

我为 kubernetes 集群安装了新的 gitlab 代理。这在我使用 KUBECTL 时有效，当我尝试使用 Helm 图表在 Azure Cloud 中部署时出现此错误。

我的 .gitlab-ci.yml

  variables:
  #registry variable
  REGISTRY: registry.gitlab.com
  #docker-image tag
  DOCKER_IMAGE_TAG: ${CI_COMMIT_SHA}
  #target variable
  TARGET: metrix9/wysiwys-ic

stages:
- build
- package
- deploy

gitlab agent:

我尝试导出 KUBECONFIG 并在管道中运行 helm repo update .. 但是出现了同样的错误......

【解决方案1】：

我正在为同样的问题而苦苦挣扎。首先使用带有 helm 和 kubectl 的图像（f.e. registry.gitlab.com/gitlab-org/cluster-integration/cluster-applications）并尝试在部署部分添加以下更改：

deploy app:
 stage: deploy-app
 variables:
  KUBE_CONTEXT: -->gitlabproject<--:-->name of the installed agent<--
 before_script:
  - if [ -n "$KUBE_CONTEXT" ]; then kubectl config use-context "$KUBE_CONTEXT"; fi
