Azure self-hosted agent kubernetes task fails

问题

我使用 Azure 自托管代理，使用 VMSS，运行代理上的 Kubernetes@1 任务时返回以下错误：couldn't get current server API group list: Get "https://<aks>.hcp.westeurope.azmk8s.io/api?timeout=32s": dial tcp: lookup <aks>.hcp.westeurope.azmk8s.io on 127.0.0.53:53: no such host。AKS 不是私有的，当在 Azure 提供的代理上运行时，此设置是有效的。我尝试运行的任务如下：

  1. steps:
  2.   - task: Kubernetes@1
  3.     displayName: "Rollout <deployment-name>"
  4.     inputs:
  5.       connectionType: "Kubernetes Service Connection"
  6.       kubernetesServiceEndpoint: <serviceEndpoint>
  7.       namespace: <namespace>
  8.       command: "rollout"
  9.       arguments: "restart deployment <deployment-name>"

代理运行在 Ubuntu 20.04 LTS 上。

使用 AzureCLI@2 任务获取凭据并执行 kubectl 命令是可行的，但这不是最佳解决方案，我想使用 Kubernetes@1 任务。以下是可行的 AzureCLI@2 任务示例：

  1. steps:
  2.  - task: AzureCLI@2
  3.     inputs:
  4.       azureSubscription: $(azureSubscription)
  5.       scriptType: bash
  6.       scriptLocation: inlineScript
  7.       inlineScript: |
  8.         az aks get-credentials --resource-group <resource-group> --name <aks-name>
  9.         kubectl rollout -n <namespace> restart deployment <deployment-name>

编辑：

  • 我使用的是服务帐户而不是 kube 配置文件。
  • 我有一个带有预安装 kubectl 命令的自定义映像。
英文:

I am using Azure self-hosted agents using VMSS, when running Kubernetes@1 task on the agent it returns this error couldn&#39;t get current server API group list: Get &quot;https://&lt;aks&gt;.hcp.westeurope.azmk8s.io/api?timeout=32s&quot;: dial tcp: lookup &lt;aks&gt;.hcp.westeurope.azmk8s.io on 127.0.0.53:53: no such host. AKS is not private and this setup was working when running on agents provided by Azure. The task I am trying to run looks like this:

  1. steps:
  2.   - task: Kubernetes@1
  3.     displayName: &quot;Rollout &lt;deployment-name&gt;&quot;
  4.     inputs:
  5.       connectionType: &quot;Kubernetes Service Connection&quot;
  6.       kubernetesServiceEndpoint: &lt;serviceEndpoint&gt;
  7.       namespace: &lt;namespace&gt;
  8.       command: &quot;rollout&quot;
  9.       arguments: &quot;restart deployment &lt;deployment-name&gt;&quot;

Agent is running on Ubuntu 20.04 LTS.

Using AzureCLI@2 task which obtains credentials and executes kubectl command does work, but it is not optimal solution and I would like to use Kubernetes@1 task. This is example of working AzureCLI@2 task:

  1. steps:
  2.  - task: AzureCLI@2
  3.     inputs:
  4.       azureSubscription: $(azureSubscription)
  5.       scriptType: bash
  6.       scriptLocation: inlineScript
  7.       inlineScript: |
  8.         az aks get-credentials --resource-group &lt;resource-group&gt; --name &lt;aks-name&gt;
  9.         kubectl rollout -n &lt;namespace&gt; restart deployment &lt;deployment-name&gt;

EDIT:

  • I am using Service Account and not kube config file.
  • I have a custom image which comes with preinstalled kubectl command.

得分: 1

Step 1: 创建 VMSS 并通过连接到 VMSS 安装 kubectl。在 VMSS 上运行以下命令以安装 kubectl。

  1. $curl -LO "https://dl.k8s.io/release/$(curl -L -s https://dl.k8s.io/release/stable.txt)/bin/linux/amd64/kubectl"
  2. $sudo install -o root -g root -m 0755 kubectl /usr/local/bin/kubectl

有关更多关于安装 kubectl 的信息，请参考这个链接。

Step 2: 将 VMSS 添加为 ADO 组织的自托管代理。

Step 3: 使用 kube config 文件创建了一个 服务连接。

Step 4: 通过选择在 step 2 中创建的池运行流水线，并验证结果。

  1.   - task: Kubernetes@1
  2.     displayName: "Rollout nginx-deployment"
  3.     inputs:
  4.       connectionType: 'Kubernetes Service Connection'
  5.       kubernetesServiceEndpoint: 'svc-aks'
  6.       namespace: 'default'
  7.       command: 'rollout'
  8.       arguments: 'restart deployment nginx-deployment'
  9.       secretType: 'dockerRegistry'
  10.       containerRegistryType: 'Container Registry'

请注意，上述是对您提供的步骤的简要翻译。如有需要，请随时提出问题。

I have followed the steps given below and it worked for me.

Step 1: Create VMSS and install a kubectl by connecting to the VMSS.
Run the below commands on VMSS to install kubectl.

  1. $curl -LO &quot;https://dl.k8s.io/release/$(curl -L -s https://dl.k8s.io/release/stable.txt)/bin/linux/amd64/kubectl&quot;
  2. $sudo install -o root -g root -m 0755 kubectl /usr/local/bin/kubectl
