I tried to find the method about undeleting the container directly, but it doesn't seem to exist.
There is a workaround using Powershell to call the Rest API.
PUT https://myaccount.blob.core.windows.net/destinationcontainer?restype=container&comp=undelete
This is the code sample:
# login
Connect-AzAccount
# get accessToken
$resource = "https://storage.azure.com"
$context = [Microsoft.Azure.Commands.Common.Authentication.Abstractions.AzureRmProfileProvider]::Instance.Profile.DefaultContext
$accessToken = [Microsoft.Azure.Commands.Common.Authentication.AzureSession]::Instance.AuthenticationFactory.Authenticate($context.Account, $context.Environment, $context.Tenant.Id.ToString(), $null, [Microsoft.Azure.Commands.Common.Authentication.ShowDialog]::Never, $null, $resource).AccessToken
#request REST API
$uri = "{Request URI}"
Invoke-RestMethod -Method 'Put' -Uri $uri -Headers @{ Authorization = "Bearer " + $accessToken }
You need to add Request Headers to make it work.
