"az ml online-deployment update" doesn't update instance_type from yaml file

[joaocc]

Hi,
We are trying to change the instance_type of an existing online-endpoint deployment from "defaultinstancetype" to something else (already created).

We updated the yaml file that was used to create the endpoint originally to point to the new instance_type

---
$schema: https://azuremlschemas.azureedge.net/latest/kubernetesOnlineDeployment.schema.json

endpoint_name: ENDPOINT_NAME_00
type: kubernetes
name: DEPLOYMENT_NAME_00

instance_type: NEW_INST_TYPE_00
# instance_type: defaultinstancetype
instance_count: 1
...

Command executed
az ml online-deployment update -f ./azml.deployment.yml -o json --resource-group RGNAME --subscription SUBS_ID --workspace-name WS_NAME

Any alternative besides the following?

• remove/redeploy endpoint+deployment
• deploy new deployment, move traffic there, to then remove previous deployment?

We were not able to finds anything in the documentation mentioning that instance_types cannot be created.
If argument is ignored, prob would be safer to either abort update or, at least, provide a warning (even if in verbose mode).

Thanks

Hi Joao, today deployment update can't change instance type. The recommended behavior is #2 as you mentioned that deploy a new deployment, move traffic there, and delete the old one. This method is much more secure than updating the old deployment itself.

Thanks.
Maybe this could be added to documentation or, as above, provided as warning on "az ml online-deployment update".
