Quick Sample to Create a VM – Azure Bicep

Hey everyone,

I’m trying out Bicep for my current side project and have created a small vm to host a PostgreSQL instance. There weren’t a lot of samples to reference in order to get this going so I thought I’d upload it:

I’ve added a github repo if you find that a little easier to go through but all of the code is available below: https://github.com/Buzzology/bicep-vm.git

Update the resource group in the parameters file and then run the following command to deploy it:

az deployment group create --template-file ./main.bicep  --parameters ./parameters/parameters.prod.json -g "{YOUR_RESOURCE_GROUP}"
// main.bicep
targetScope = 'subscription' // tenant', 'managementGroup', 'subscription', 'resourceGroup'

param vmPgsqlUsername string
param vmPgsqlPassword string
param resourceGroupName string = 'not-set'
param namePrefix string = 'not set'


module vnet_generic './vnets/vnet-generic.bicep' = {
  name: 'vnet'
  scope: resourceGroup(resourceGroupName)
  params: {
    namePrefix: '${namePrefix}-vnet'
  }
}


module vm_pgsql './virtual-machines/postgresql/vm-postgresql.bicep' = {
  name: 'vm-pgsql'
  scope: resourceGroup(resourceGroupName)
  params: {
    namePrefix: '${namePrefix}-vm'
    subnetId: vnet_generic.outputs.subnetId
    username: vmPgsqlUsername
    password: vmPgsqlPassword
  }
}
 

output vmName string = vm_pgsql.name
// vnets\vnet-generic.bicep
param namePrefix string = 'unique'
param location string = resourceGroup().location

var name = '${namePrefix}-${uniqueString(resourceGroup().id)}'
var subnetName = 'main-subnet'

resource vnet_generic 'Microsoft.Network/virtualNetworks@2020-08-01' = {
  name: name
  location: location
  properties: {
    addressSpace: {
      addressPrefixes: [
        '10.0.0.0/24'
      ]
    }
    subnets: [
      {
        name: subnetName
        properties: {

          privateEndpointNetworkPolicies: 'Enabled'

        }
      }
    ]
    virtualNetworkPeerings: []
    enableDdosProtection: false
  }
}


output vnetId string = vnet_generic.id
output subnetId string = '${vnet_generic.id}/subnets/${subnetName}'

// virtual-machines\gneral\vm-small

          }
          primary: true
