Where is the value of deployment().name coming from in Azure Deployment? - azure

Question

As part of our template files, we have a variable defined partially by deployment method's deployment().name, similar to this:
"myVariable": "[concat(SOME_CUSTOM_STRING_HERE, deployment().name)]"
The variable is then used as the deployment label for our Classic Cloud Service resources which includes the build number.
{
"apiVersion": "2015-12-01",
"type": "deploymentSlots",
"name": "staging",
"properties": {
"deploymentLabel": "[variables('myVariable')]",
...
},
...
}
Perhaps deployment().name can be set and not defined by Azure, but I haven't been able I haven't been able to find it.
However, the variable's value is different under Cloud Service Extended Support. This time the value is a long hash and the name of the Cloud Service resource, even thought the definition remains as shown above. The variable is used in a tag:
{
"apiVersion": "2021-03-01",
"type": "Microsoft.Compute/cloudServices",
"name": "RESOURCE_NAME",
"location": "[LOCATION]",
"tags": {
"DeploymentLabel": "[variables('myVariable')]",
...
},
...
}
So did the value of deployment().name template function change for deployments of Extended Support version of cloud service? If not, can it be set and how?

Answer 1

From the Azure Devops side, if you are running the deployment the task itself has the deployment name like deployment mode. if its not provided, automatically it gets generated
deploymentMode: 'Incremental'
deploymentName: 'deploymentname'
if its powershell then please check the link below

Answer 2

you set the name when you deploy a resource:
{
"apiVersion": "2021-03-01",
"type": "Microsoft.Compute/cloudServices",
"NAME": "MYRESOURCE",
"location": "[LOCATION]",
"tags": {
"DeploymentLabel": "[variables('myVariable')]",
...
},
...
}
