Issue:
AKS unable to pull image from ACR.
Solution:
The problem was building the Docker image on a MacBook (ARM architecture) but deploying on an amd64 environment. The fix was to build the image for amd64:
docker buildx build --platform linux/amd64 -t <image-name>:amd64 .
After pushing the image to ACR, deployment could pull and run it successfully. This ensures compatibility for ARM-to-amd64 deployments.
If you have any other questions or are still running into more issues, please let me know. Thank you again for your time and patience throughout this issue.
