Azure DevOps - 应用服务 - 并行插槽交换

Question

This Deploy Task is super cool. I want to do two at once. Is there a way to do this via DevOps tasks? If not are there any know work-arounds? I tried this with Azure PowerShell but the commands didn't fire, even though it works locally :(

Start-Job -Name API {
    #Switch-AzureRmWebAppSlot -SourceSlotName "staging" -DestinationSlotName "production" -ResourceGroupName "CoolResGroup" -Name "something-api-east"
}

Write-Host "API Staging <-> Prod swap initiated"

Start-Job -Name Web {
    #Switch-AzureRmWebAppSlot -SourceSlotName "staging" -DestinationSlotName "production" -ResourceGroupName "CoolResGroup" -Name "something-web-east"
}

Write-Host "Web Staging <-> Prod swap initiated"

Wait-Job -Name API
Wait-Job -Name Web

If (Get-Job -Name API -ea silentlycontinue)
{
    Write-Host "API state: $((Get-Job -Name API).State)"
} 
Else 
{
    Write-Host "API slot swap complete."
}

If (Get-Job -Name Web -ea silentlycontinue)
{
    Write-Host "Web state: $((Get-Job -Name Web).State)"
} 
Else 
{
    Write-Host "Web slot swap complete."
}

By default those powershell cmdlets are blocking, so you either need to start them in a background thread, or convert them to API calls (they shouldn't be blocking). This way you can perform those 2 calls more or less at the same time.

This would, however, complicate your flow, as you'd need to detect if both swaps completed fine (so an extra check you'd need to make).

Alternatively you are better of using A\\B deployments. Links: https://www.hanselman.com/blog/ABTestingAndTestingInProductionWithAzureWebApps.aspx
