I have deployed a windows container which runs successfully in my local sytem using docker. Moved the image to Azure container registry and deployed the image from ACR to Azure Container service kubernetes cluster cluster. It says it has been deployed successfully but we can't access it using the public IP assigned to it.
Docker File
# The `FROM` instruction specifies the base image. You are
# extending the `microsoft/aspnet` image.
FROM microsoft/aspnet
# The final instruction copies the site you published earlier into the container.

Added the security rules for ACS to access ACR repos as stated in this link - https://thorsten-hans.com/how-to-use-a-private-azure-container-registry-with-kubernetes-9b86e67b93b6 and updated my docker file as below fixed my issues,

CMD ["ping", "-t", "localhost"]
your pod fails to get created due to you not having secret for ACR:
kubectrl create secret docker-registry <SECRET_NAME> --docker-server <REGISTRY_NAME>.azurecr.io --docker-email <YOUR_MAIL> --docker-username=<SERVICE_PRINCIPAL_ID> --docker-password <YOUR_PASSWORD>
