iotedge: Edge running on AKS is not updating module images with new tag and version in IotHub

Hey all,

We have an edge device running on AKS and our release pipeline on every deployment updates the image tag as well as module version. We are using automatic deployments. I see that the deployments are being applied on the devices, but the module image is actually not updating iot hub.

I have been using Helm chart from below https://edgek8s.blob.core.windows.net/staging

Screenshot for reference:

Edge agent version: Version - 1.0.10-dev.35780923 (0d09dc260e49baed02df9021a0046610d081bc0a) Edge agent image: azureiotedge/azureiotedge-agent:0.1.0-beta11 Iotedged image: azureiotedge/azureiotedge-iotedged:0.1.0-beta11

Also, Iotedged pod seems to be generating every log as error.

Expected Behavior

Tell us what should happen Module images should be correctly updated whenever a new deployment is made with different image tag.

Current Behavior

Module images are still showing old values while the deployment is already applied to edge device.

Steps to Reproduce

Provide a detailed set of steps to reproduce the bug.

1. Setup an edge device in AKS cluster
2. Create a deployment and apply it to the device.
3. Create another deployment with same priority and update the module tag to a higher version.
4. Validate image tag in Iot Hub.

Context (Environment) - PreProd
