I have created an Azure Function App via Terraform (code attached).
I have created a Dockerfile with my requirements and have pushed to ACR. My ACR has ACRPull permission.
After executed terrraform apply and azure function got created, the docker container is not running inside the function app.
After my function app got created in the Overview section I can Error in Runtime Version
I want my docker container to get executed inside the app after the function app is created successfully.
Attaching all logs and snapshots regarding the same.
Can I have some help on this issue please so that I can successfully run my docker container inside function app?

Sakshi Kokardekar 205 Reputation points MVP2025-03-26T16:37:02.1833333+00:00 It seems like your Azure Function App is not properly connecting to your Azure Container Registry (ACR) or there might be a configuration issue with the runtime stack. After applying Terraform, if you’re seeing a runtime version error, it could indicate that the function app is not set to use a custom container. I think you should once Double-check the linux_fx_version setting in your Terraform configuration—it should be set to the correct format, such as DOCKER|<ACR_NAME>.azurecr.io/<IMAGE_NAME>:<TAG>. Also, ensure that the app service has the correct identity with ACRPull permission and the WEBSITES_ENABLE_APP_SERVICE_STORAGE is set to false if you want to run the container statelessly. Review the logs for container startup failures, and verify that the ACR authentication is configured properly.
