使用BICEP实现Azure资源自动创建 - BICEP模块

使用BICEP实现Azure资源自动创建 - BICEP模块

BICEP一个非常大的进步就是可以支持module，类似于在terraform中做的一样，这种模式可以极大减少代码的冗余，让整个项目的结构变得更精简，直观

同样地，BICEP中模块的使用也不复杂，如果之前了解过terraform的话，相信上手起来应该会非常快

这次就用一个简单的例子做个demo

整体文件结构

--|main.bicep

--|modules/storage.bicep

--|modules/appService.bicep

简单做个说明，详细的云资源的定义是放在modules文件夹里，modules中的内容是可以给多个项目或者场景公用的，所以一般这里要定义的内容会非常多，而main文件中只是引用modules中的内容，然后给一些参数进行赋值即可，类似于编程语言中函数的定义和调用一样，基本是一个道理，还是比较容易理解的

modules/storage.bicep

@description('location which resources should be deployed')param location string = resourceGroup().location@description('name of storage account')@minLength(6)@maxLength(24)param storageAccountName string@description('kind of storage account')@allowed([ 'BlobStorage' 'BlockBlobStorage' 'FileStorage' 'Storage' 'StorageV2'])param storageAccountKind string = 'StorageV2'@description('sku of storage account')@allowed([ 'Premium_LRS' 'Premium_ZRS' 'Standard_GRS' 'Standard_GZRS' 'Standard_LRS' 'Standard_RAGRS' 'Standard_RAGZRS' 'Standard_ZRS'])param storageAccountSKU string = 'Standard_LRS'resource storageaccount 'Microsoft.Storage/storageAccounts@2021-02-01' = { name: storageAccountName location: location kind: storageAccountKind sku: { name: storageAccountSKU }}

modules/appService.bicep

@description('location which resources should be deployed')param location string = resourceGroup().location@description('name of app service plan')param appServicePlanName string@description('sku of app service plan')param appServiceSkuName string@description('capacity of app service plan')param appServiceCapacity int = 1@description('name of app service')param appServiceName string@description('OS of app service')@allowed([ 'Linux' 'Windows'])param appServicePlanKind string = 'Linux'resource appServicePlan 'Microsoft.Web/serverfarms@2020-12-01' = { name: appServicePlanName location: location sku: { name: appServiceSkuName capacity: appServiceCapacity } properties:{ reserved:true } kind:appServicePlanKind}resource webApplication 'Microsoft.Web/sites@2021-02-01' = { name: appServiceName location: location tags: { 'hidden-related:${resourceGroup().id}/providers/Microsoft.Web/serverfarms/appServicePlan': 'Resource' } properties: { serverFarmId: appServicePlan.id siteConfig:{ linuxFxVersion:'DOTNETCORE|3.1' } }}

main.bicep

@description('The name of the environment. This must be dev, test, or prod.')@allowed([ 'dev' 'test' 'prod'])param environmentName string = 'dev'@description('storage account name')param storageAccountName string = 'sa${take(uniqueString(resourceGroup().id), 10)}'@description('The number of App Service plan instances.')@minValue(1)@maxValue(10)param appServicePlanInstanceCount int = 1@description('sku of app service plan')param appServiceSkuName string = 'F1'@description('The Azure region into which the resources should be deployed.')param location string = resourceGroup().locationvar appServicePlanName = '${environmentName}-bicep-plan'var appServiceAppName = '${environmentName}-bicep-app'module appService 'modules/appService.bicep' = { name: 'appService' params:{ appServiceName:appServiceAppName appServicePlanName:appServicePlanName appServiceSkuName:appServiceSkuName location:location } }module storage 'modules/storage.bicep' = { name:'storage' params:{ storageAccountName:storageAccountName location:location storageAccountSKU:(environmentName == 'prod')? 'Standard_GRS' : 'Standard_LRS' }}

先用what-if 检查下

az deployment group what-if --template-file .\main.bicep --resource-group bicep

部署

az deployment group what-if --template-file .\main.bicep --resource-group bicep
