多行 overrideValues Helm 安装 Azure DevOps

Question

是否可以在 Azure devOps 管道的 HelmDeploy 任务中指定要覆盖的值？例如，类似于下面的任务（显然不能完全按原样工作）：

  - task: HelmDeploy@0
              displayName: 'helm install'
              inputs:
                connectionType: 'Azure Resource Manager'
                azureSubscription: '$(RM_SERVICE_CONNECTION_NAME)'
                azureResourceGroup: '$(AKS_RESOURCE_GROUP)'
                kubernetesCluster: '$(AKS_NAME)'
                namespace: '$(AKS_NAMESPACE)'
                command: 'install'
                chartType: 'FilePath'
                chartPath: '$(deploymentChartName)'
                releaseName: test-release
                overrideValues: |
                  value1='value_1'
                  value2='value_2'

是否有任何类似于上述示例的格式可用？

Answer 1

恐怕overrideValues字段不能接受多行覆盖变量。正如 document 所说，多个值应该用逗号分隔值 key1=val1,key2=val2.

不过，您可以尝试使用 arguments 字段并传递变量。

见下文：

  - task: HelmDeploy@0
    displayName: 'helm install'
    inputs:
       connectionType: 'Azure Resource Manager'
       azureSubscription: '$(RM_SERVICE_CONNECTION_NAME)'
       ...
       ...
       arguments: >
          --set foo=bar
          --set foo1=bar1
          --set foo2=bar2

Answer 2

事实上，这个问题中的语法就是这样。新行以逗号连接。

documentation.

中也有说明

(Optional) Set values on the command line. You can specify multiple values by separating values with commas. For example, key1=val1,key2=val2. You can also specify multiple values by delimiting them with newline as so:
key1=val1
key2=val2
Please note that if you have a value which itself contains newlines, use the valueFile option, else the task will treat the newline as a delimiter. The task will construct the helm command by using these set values. For example, helm install --set key1=val1 ./redis

我在我的所有管道中都使用了这种语法，并且它按预期运行。

overrideValues: |
    value1='value_1'
    value2='value_2'

我们在这里使用管道的原因是我们想保留新行。此标准 yaml 语法记录在案 here.

Block Style Indicator: The block style indicates how newlines inside the block should behave. If you would like them to be kept as newlines, use the literal style, indicated by a pipe (|). If instead you want them to be replaced by spaces, use the folded style, indicated by a right angle bracket (>). (To get a newline using the folded style, leave a blank line by putting two newlines in. Lines with extra indentation are also not folded.)

回到值，如果单个值包含文档中所述的新行或根据我自己的经验包含空格，那么事情就会出现问题。这里建议的方法是使用值文件。
