Use custom base images or images other than default ones on deployment Scripts?

Question

Following the documentation - A Bicep deployment script runs within an Azure Container Instance (ACI), which pulls an image from the Microsoft Container Registry. The documentation states:

"The ACI downloads container images from the Microsoft Container Registry. If you use a firewall, allowlist the URL mcr.microsoft.com to download the image."

I would like to know if it's possible to use a custom image instead of the default one pulled from the MCR. My goal is to use a custom image that allows me to pull modules from JFrog or a private registry from the deployment script. Would this be supported?

Answer 1

Apologies - clearly I misread your question.

AFAIK, this is not supported. You can verify this by reviewing the resource definition https://learn.microsoft.com/en-us/azure/templates/microsoft.resources/deploymentscripts?pivots=deployment-language-bicep

Answer 2

Yep - follow https://learn.microsoft.com/en-us/azure/container-instances/container-instances-quickstart-bicep?tabs=CLI

In particular, @description('Container image to deploy. Should be of the form repoName/imagename:tag for images stored in public Docker Hub, or a fully qualified URI for other registries. Images from private registries require additional registry credentials.')
