Changing the 
image
of a Kubernetes Deployment is not displayed as a change with 
pulumi up --refresh
. I changed it directly with 
kubectl edit
. The details view of 
pulumi up
shows that the 
image
will be refreshed in the stack, though. What do I do wrong? (The code is from 
pulumi new kubernetes-typescript
with fixed 
image
& 
minikube
provider.)
k8s_simple-change-detection-failure.ts
Simple test: 
kubectl edit deploy nginx-...
& change to 
image: nginx:1.16.1-alpine
`pulumi version`: 
v1.2.0
package.json

@future-barista-68134 are you able to assist with this?

Sure, I can take a look at this for you Dominik. Looks like you're trying to POC out the kubernetes functionality?

No, just created a MWE to test if it occurs there, as well. Do you get the same result? I stumbled upon this behaviour sometimes. Last while deploying 
kube-prometheus
which has many K8s resources.
I’m seeing the change in the details of the 
refresh
stage (either 
pulumi refresh
or 
pulumi up --refresh
). But I don’t see that 
pulumi up
doesn’t want to change the image back to what’s defined in the code, i.e. 
nginx:1.6.1
.
@future-barista-68134 I’ve found that this bug is already in an issue: https://github.com/pulumi/pulumi-kubernetes/issues/694
@microscopic-florist-22719 indicated that this is expected behavior with legacy diff because the kubectl scale command apparently doesn’t set the 
<http://kubectl.kubernetes.io/last-applied-configuration|kubectl.kubernetes.io/last-applied-configuration>
annotation.
The solution is to use the new Kubernetes provider option 
enableDryRun: true
(hint: there may be stability issues with it as mentioned in the Github issue).

Okay, I've made the engineering team aware. Currently is there anything about using enableDryRun that will block you from your desired workflow for now?

@future-barista-68134 No, using 
enableDryRun
seems fine for now. Didn’t use it in bigger projects, yet. Currently working on other things. Sorry for the late answer. Just realized that I don’t get any notification from threads. Best is you always @mention me. Then it’s sure I’ll receive a notification.
