Azure deployment cfn-signal equivalent?

Question

I am utilizing cloud-init for my deployments both in AWS and Azure.

In AWS I can signal success/failure using cfn-signal to my CloudFormation stack. In Azure I have not found anything similar.

Example cloud-init:

#cloud-config
write_files:
  - path: /etc/my_script.sh
    permissions: '0775'
    content: |
      #!/bin/bash
      set -Eeuo pipefail

      trap error_report ERR

      error_report() {
        # Some error reporting stuff, including
        cloud-init collect-logs
        # Send them somewhere
        # cfn-signal -e 1 # Present in AWS-version only
      }

      echo 'This is a successful command'
      # some other commands that might fail
      cfn-signal -e 0     # Present in AWS-version only
runcmd:
  - [ bash, /etc/my_script.sh ]

Failing runcmd does not fail the whole cloud-init configuration. I am missing the piece where I can somehow signal the deployment either a success or failure. Failure would be enough, really.

Any help is greatly appreciated. Thanks in advance.

Its not supported.

so that product teams takes this into backlog and work on it.

But you have a lengthy workaround. You can have a custom script extension along with the cloud init.
In the custom script extension , you can have a loop to check for the required condition for the specified time.
Once the conditions achieved, Then you can exit the script with 0 exit code. If that times out or fails, Then exit the script with failure exit code. With that you can identify in ARM template
