AtlasDeployment stuck in deployment is updating state

[vmanikes]

What did you do to encounter the bug?
Steps to reproduce the behavior:
I have a deployment with autoscaling enabled

            autoScaling:
              compute:
                enabled: true
                maxInstanceSize: M20
                minInstanceSize: M10
                scaleDownEnabled: true
              diskGB:
                enabled: true

Now when I change scaleDownEnabled: false, the deployment is stuck in updating state

NAME         READY   ATLAS STATE   MONGODB VERSION
data-vault   False   UPDATING      8.0.4

And when I describe

Events:
  Type    Reason              Age                     From             Message
  ----    ------              ----                    ----             -------
  Normal  DeploymentUpdating  4m47s (x3600 over 32d)  AtlasDeployment  deployment is updating

What did you expect?
Deployment should have been updated successfully

What happened instead?
Deployment is stuck in a loop

This is definitely a bug. To disable autoscaling I had to remove the autoscaling block from the spec entirely and I had to look at the source code to comprehend this.

P.S the autoscaling actually gets disabled when I set autoscaling.enabled = false but the deployment never becomes ready

Hi @vmanikes,
Thanks for the report. We are actively looking into the issue.

Hi @vmanikes!

Thank you, again, for bringing this issue to our attention. Our team has successfully reproduced the error, and we can confirm it is a bug. As a temporary workaround, you can remove autoscaling configuration and add it back once the cluster is idle, as you have already discovered. Our team is actively investigating a more permanent solution by assessing the possibility of removing the validation constraints around autoscaling without impacting the usability of the resource. Please note that developing and testing a proper fix might take some time. We appreciate your patience and will keep you updated on our progress.
