使用 terraform 配置程序“local-exec”运行 shell 脚本会返回 Azure DevOps 中拒绝的权限返回拒绝的权限

Question

我正在尝试使用带有 null_resource 和 local-exec 的 pat 令牌来配置数据块。这是代码块：

resource "null_resource" "databricks_token" {
  triggers = {
    workspace = azurerm_databricks_workspace.databricks.id
    key_vault_access = azurerm_key_vault_access_policy.terraform.id
  }
  provisioner "local-exec" {
    command = "${path.cwd}/generate-pat-token.sh"
    environment = {
      RESOURCE_GROUP = var.resource_group_name
      DATABRICKS_WORKSPACE_RESOURCE_ID = azurerm_databricks_workspace.databricks.id
      KEY_VAULT = azurerm_key_vault.databricks_token.name
      SECRET_NAME = "DATABRICKS-TOKEN"
      DATABRICKS_ENDPOINT = "https://westeurope.azuredatabricks.net"
    }
  }
}

但是，我收到以下错误：

旁注，这是 Azure DevOps

知道如何解决权限被拒绝的问题吗？

Answer 1

此问题的根源在于 Azure DevOps 如何存储项目和存储库。这是他们文档中的一个片段，解释了为什么会发生这种情况。

https://learn.microsoft.com/en-us/azure/devops/pipelines/artifacts/build-artifacts?view=azure-devops&tabs=yaml#download-to-debug

在提示部分下，您将看到以下内容：

• 构建工件存储在 Windows 文件系统上，这会导致所有 UNIX 权限丢失，包括执行位。从 Azure Pipelines 或 TFS 下载项目后，您可能需要恢复正确的 UNIX 权限。

这意味着您下载的文件（在本例中为 shell 脚本）已擦除所有 UNIX 权限。为了解决这个问题，我添加了一个步骤，在执行 shell 脚本之前首先对 shell 脚本设置适当的权限。请参阅下面的示例，其中我已将修复添加到您提供的代码中。

resource "null_resource" "databricks_token" {
  triggers = {
    workspace = azurerm_databricks_workspace.databricks.id
    key_vault_access = azurerm_key_vault_access_policy.terraform.id
  }
  provisioner "local-exec" {
    command = "chmod +x ${path.cwd}/generate-pat-token.sh; ${path.cwd}/generate-pat-token.sh"
    environment = {
      RESOURCE_GROUP = var.resource_group_name
      DATABRICKS_WORKSPACE_RESOURCE_ID = azurerm_databricks_workspace.databricks.id
      KEY_VAULT = azurerm_key_vault.databricks_token.name
      SECRET_NAME = "DATABRICKS-TOKEN"
      DATABRICKS_ENDPOINT = "https://westeurope.azuredatabricks.net"
    }
  }
}

命令部分首先会设置shell脚本的执行权限，然后执行。
