带有自托管代理的azure devops : can't deploy to aks cluster

Question

我想创建 azure devops 发布管道来构建 docker 镜像并将其部署到 aks 集群。

对 acr 的构建和部署运行良好，但对 aks 的部署不起作用。

这是运行管道后的结果:

这是错误日志:

Unable to connect to the server: dial tcp: lookup xxxx on192.168.1.1:53: no such host

您似乎正在使用私有(private)群集(创建 AKS 群集时启用了“私有(private)群集”选项)。

Kubectl 是一个 kubernetes 控制客户端。它是与 kubernetes 集群连接的外部连接提供程序。我们无法从外部连接私有(private)集群。

但是，在创建集群后我们无法禁用此选项。我们需要删除集群并创建一个新集群，并禁用“私有(private)集群”选项。

或者，您可以设置另一个自托管代理，该代理将与群集位于同一 Vnet 中，并有权访问 AKS 和 Azure Pipelines。

参见Options for connecting to the private cluster

The API server endpoint has no public IP address. To manage the APIserver, you'll need to use a VM that has access to the AKS cluster'sAzure Virtual Network (VNet). There are several options forestablishing network connectivity to the private cluster.

• Create a VM in the same Azure Virtual Network (VNet) as the AKS cluster.
• Use a VM in a separate network and set up Virtual network peering. See the section below for more information on this option.
• Use an Express Route or VPN connection.
• Use the AKS command invoke feature.
• Use a private endpoint connection.

Creating a VM in the same VNET as the AKS cluster is the easiestoption. Express Route and VPNs add costs and require additionalnetworking complexity. Virtual network peering requires you to planyour network CIDR ranges to ensure there are no overlapping ranges.
