webapps-deploy silently fails to update DOCKER_CUSTOM_IMAGE_NAME when using publish-profile auth with named image tags

[ajaymahadeven]

• Steps to reproduce: deploy a container app using publish-profile with a named tag (e.g. v2.5.4) — action reports success but DOCKER_CUSTOM_IMAGE_NAME retains the previous value
• Expected: container image config updated to the new tag
• Actual: config unchanged, app continues running old image
• Workaround: use azure/login + AZURE_CREDENTIALS instead of publish-profile
• Action version: v3
• App type: Azure Function App, Linux, container

Hey Ajay Mahadeven (@ajaymahadeven),
This looks a very basic scenario of container deployment so it is supposed to be working but I will repro it and get back to you.
Thank you for providing detailed description.

Hi Akshay Kumar (@kumaraksh1) , Did you have a chance to look at this.. Please and thank you.

Hey Ajay Mahadeven (@ajaymahadeven),
Thank you for being patient.

Your app is a Function App as you already mentioned (App type: Azure Function App, Linux, container).
Webapp-deploy can be used to deploy Function App and can be debugged why It's not working with publish profile but
I will highly recommend you use functions-actions for deploy a function app

Function-Actions - https://github.com/Azure/functions-action

I am closing this issue, feel free to reopen if you need it :)

Hi Akshay Kumar (@kumaraksh1),

Unfortunately, that's not possible in our case. We're using a custom Docker image for our Azure Function App, which requires containerisation and an App Service Plan.

The issue isn't about deploying a Function App—it's specifically that webapps-deploy with publish-profile auth doesn't update DOCKER_CUSTOM_IMAGE_NAME, even though the action reports success.

Could this please be reopened, as the underlying issue hasn't been addressed?

Thanks.

Hey Ajay Mahadeven (@ajaymahadeven),
I have re-opened the issue, let me investigate further.
