从jenkins访问用于桌面的kubernetes docker

标签： docker jenkins kubernetes

我已经为台式机安装了一个kubernetes docker，它工作正常。然后，我安装并配置了一个詹金斯容器。 现在，我想从jenkins容器部署到kubernetes。 我安装了Kubernetes Continuous Deploy插件，并使用“ kubectl config view”命令的结果配置了凭据

apiVersion: v1
clusters:
- cluster:
    insecure-skip-tls-verify: true
    server: https://localhost:6445
  name: docker-for-desktop-cluster
contexts:
- context:
    cluster: docker-for-desktop-cluster
    user: docker-for-desktop
  name: docker-for-desktop
current-context: docker-for-desktop
kind: Config
preferences: {}

当我尝试从jenkins部署到kubernetes时，出现此错误

显然错误是kubernetes的地址，但我不知道如何检索正确的地址。 我尝试了在Service > Kubernetes > Deploy下的kubernetes中可以看到的那个，但是它不起作用。在哪里可以找到正确的？

1 个答案:

答案 0 :(得分：0)

您的问题出在kubeconfig文件中，准确地说，在以下部分中：

  

服务器：https://localhost:6445

它当然在本地机器的上下文中有效，但是当您尝试使用它从节点/代理jenkins容器内部访问Kubernetes集群时无效。容器具有唯一的主机名，因此从容器与https://localhost地址进行通信就像在自言自语。

解决方案：

请用“ host.docker.internal”，“ docker.for.win.localhost”（如果您在Windows上）或仅将本地计算机的本地IP地址替换为“ localhost”，如下所示：

apiVersion: v1
clusters:
- cluster:
    insecure-skip-tls-verify: true
    server: https://docker.for.win.localhost:6445
  name: docker-for-desktop-cluster
contexts:
- context:
    cluster: docker-for-desktop-cluster
    user: docker-for-desktop
  name: docker-for-desktop
current-context: docker-for-desktop
...
