SCM_DO_BUILD_DURING_DEPLOYMENT is set to false explicitly by Azure Cli

Question

I am using Azure Cli in Jenkins build to deploy my nodejs azure functions to azure. I need Kudu to build the npm packages to reduce the deployment time on Jenkins side.

I have SCM_DO_BUILD_DURING_DEPLOYMENT = true in Azure Functions configurations but Azure Cli explicitly set it to false while deploying the artifacts! So the application will be left out without node_modules folder.

I am using command similar to the following:

az functionapp deployment source config-zip --src artifacts.zip --resource-group MyGroup --subscription MySubscription --name MyFunction --slot pre

Any idea how to fix it?

Answer 1

It seems that there was a similar issue with a version regression in the past. Check out the issue around this: https://github.com/Azure/azure-cli/issues/11246

You can install Azure CLI 2.0.77 or 2.0.75 using pip and see if this issue is vanished:

pip install azure-cli==2.0.75

May be, this is an issue with a latest update.

I am using the latest Azure Cli docker container (v 2.13.0). Is not supposed to be fixed there? – Happ

Can you try rolling back to these versions once? So that it can be confirmed if it's an update or something else. – Cribble

Pipe caused some errors but I used mcr.microsoft.com/azure-cli:2.0.77 and result was the same. There are 2 warning messages Setting ENABLE_ORYX_BUILD to false and Setting SCM_DO_BUILD_DURING_DEPLOYMENT to false. – Happ

Adding $env:SCM_DO_BUILD_DURING_DEPLOYMENT=true in my script solved this problem

Sharyl

could you please explain the syntax you have used above? I am trying to understand how and where you set the value SCM_DO_BUILD_DURING_DEPLOYMENT=true – Rochelle

Those are PowerShell script used to set environment variable, I think he sets the env var before running Azure CLI – Earthstar

Answer 3

I also faced this issue when using the az functionapp deployment source config-zip command. When this command is executed, the value of SCM_DO_BUILD_DURING_DEPLOYMENT set to true in the function app's application settings will be overridden and changed to false.

To prevent that, set the --build-remote flag to true.
E.g. az functionapp deployment source config-zip --src artifacts.zip --resource-group MyGroup --subscription MySubscription --name MyFunction --slot pre --build-remote true

There is apparently also the option to include a .deployment file with the config in it.

See: https://learn.microsoft.com/en-us/azure/azure-functions/deployment-zip-push#deployment-customization
