Describe the bug

The DNS record is not deleted with the Complete deployment mode.

Command Name az deployment group create

Errors:

To Reproduce:

1. Create bicep file sample.dns.bicep:

   
   param zoneName string  = 'my.local'
   var defaultTtl = 3600

resource zone 'Microsoft.Network/dnsZones@2018-05-01' = { name: zoneName location: 'global' }

resource _root_A 'Microsoft.Network/dnsZones/A@2018-05-01' = { name: '@' parent: zone properties: { TTL: defaultTtl ARecords: [ { ipv4Address: '1.1.1.1' } ] } }

2. Run the deployment
`az deployment group create --name test1 --resource-group dns-test  --template-file .\sample.dns.bicep --mode Complete`
All good, records created
3. Change the file to (so remove the record):

param zoneName string = 'my.local' var defaultTtl = 3600

resource zone 'Microsoft.Network/dnsZones@2018-05-01' = { name: zoneName location: 'global' }

2. Run the deployment
`az deployment group create --name test1 --resource-group dns-test  --template-file .\sample.dns.bicep --mode Complete`

Deployment is OK, but record is still there.

Hello, I'm also facing the same problem. Is there any chance to resolve it in near future? My az version: azure-cli 2.51.0

[viniciushsantana]

Still happening on Azure CLI 2.61.0.

This seems to be intentional, this case is described in the docs: https://learn.microsoft.com/en-us/azure/azure-resource-manager/templates/deployment-modes
