Azure Function Apps can occasionally encounter challenges in downloading the required PowerShell modules within the 10-minute timeout period imposed by Microsoft during startup. To mitigate this issue, you can preload large PowerShell modules directly into the Function App’s storage, ensuring they are readily available without relying on external downloads during the initialization process. In this post, we’ll walk through all the necessary steps to ensure the required PowerShell modules are available in your Azure Function App.<\/p>\n\n\n\n
Creating the Function App<\/h1>\n\n\n\n
\n
Head to the Azure Portal and create a Function App. <\/li>\n\n\n\n
As of 24.09.2024 be sure to use PS Core 7.4 or newer. <\/li>\n\n\n\n
Create a new storage account and add the Azure Files connection. <\/li>\n\n\n\n
Public access can be disabled, we\u2019ll enable IP based access later on: <\/li>\n\n\n\n
To add application insights, it might need a new log analytics workspace. <\/li>\n\n\n\n
Skip continuous deployment, assign relevant tags and create the function app. <\/li>\n<\/ul>\n\n\n\n
Configuration of relevant settings<\/h1>\n\n\n\n
With our newly created Function App, we can start configuring all the relevant settings.<\/p>\n\n\n\n
\n
First, it’s a good practice to restrict public access to your Function App unless explicitly required. Begin by modifying the access restrictions to limit interaction to your specific public IP address. Navigate to Settings > Networking > Public Network Access<\/strong>, and set it to Disabled<\/strong>. This will block general public access to your Function App. Later, we’ll configure IP-based access to ensure secure communication.<\/li>\n<\/ul>\n\n\n\n
<\/p>\n\n\n\n
\n
Add the Public IP(s) from which you\u2019ll be managing the Function App. <\/li>\n\n\n\n
Navigate to Functions<\/strong> > App files<\/strong>, select host.json<\/strong>, and set the functionTimeout<\/strong> to the maximum of 10 minutes. Additionally, set managedDependency<\/strong> to false<\/strong>. Be aware that if you use managed dependencies, it may take several minutes to download the PowerShell module. Instead, we’ll upload the PowerShell module directly into the Function App storage.<\/li>\n<\/ul>\n\n\n\n
