title: How do I override/add parameters using Azure AZ
body: <p>Previously my script looked like this using AzureRM</p>
  
  <pre><code>New-AzureRmResourceGroupDeployment `
  -Name LocalTestDeployment `
  -ResourceGroupName xxx-${env}-${location} `
  -Mode Incremental `
  -TemplateFile ..\webapp\azuredeploy.json `
  -TemplateParameterFile ..\webapp\azuredeploy.parameters-dev.json `
  -azureEnvironment ${env} `
  -locationKey ${location}
  </code></pre>
  
  <p>How would I do the same in Azure AZ?</p>
  
  <p>This is how far I have gotten from what I can find in the documentation, but how do I do with the last two lines where I override/add extra properties to the template?</p>
  
  <pre><code>az group deployment create `
  --name LocalTestDeployment `
  --resource-group xxx-${env}-${location} `
  --mode Incremental `
  --template-file ..\webapp\azuredeploy.json `
  --parameters `@..\webapp\azuredeploy.parameters-dev.json `
  -azureEnvironment ${env} `
  -locationKey ${location}
  </code></pre>
