az containerapp job update overwrites all scale rules instead of updating one

[acidbubbles]

Describe the bug

Run a command like this one:

az containerapp job update --name $NAME --resource-group $RG --scale-rule-name $SR_NAME --scale-rule-type "azure-queue" --scale-rule-metadata "accountName=$ACCOUNT_NAME" "queueName=$QUEUE_NAME" "queueLength=1" --scale-rule-auth "connection=connection-string-secret"

It will effectively create the desired scale rule. However, it will also delete all other existing scale rules.

I want to keep two scale rules.

Errors

Other scale rules deleted

Hi @acidbubbles

Yes, currently with az containerapp job update --name $NAME --resource-group $RG --scale-rule-name $SR_NAME --scale-rule-type "azure-queue" --scale-rule-metadata it will delete other scale rules.

There is a workaround:
use az containerapp job update --yaml to input all existing scale rules and new added scale rules.
You can use command
az containerapp show --name $NAME --resource-group $RG -o yaml to get the existing setting.

Thank you, that sounds like a reasonable workaround, I appreciate the info! Since there is no UI in the Azure Portal for the azure queue rules metadata yet, this behavior can be quite confusing and hard to spot.
