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.

Answer 2

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

Answer 3

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

Answer 4

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
