The Azure Functions Core Tools provide a local development experience for creating, developing, testing, running, and debugging Azure Functions.

v1 (v1.x branch): Requires .NET 4.7.1 Windows Only

v2 (master branch): Self-contained cross-platform package

Both v1 and v2 of the runtime can be installed on Windows.

To install v2:

npm i -g azure-functions-core-tools@core --unsafe-perm true

Homebrew:

brew tap azure/functions
brew install azure-functions-core-tools

1. Register the Microsoft Product key as trusted.

curl https://packages.microsoft.com/keys/microsoft.asc | gpg --dearmor > microsoft.gpg
sudo mv microsoft.gpg /etc/apt/trusted.gpg.d/microsoft.gpg

2. Set up package feed

sudo sh -c 'echo "deb [arch=amd64] https://packages.microsoft.com/repos/microsoft-ubuntu-artful-prod artful main" > /etc/apt/sources.list.d/dotnetdev.list'
sudo apt-get update

sudo sh -c 'echo "deb [arch=amd64] https://packages.microsoft.com/repos/microsoft-ubuntu-zesty-prod zesty main" > /etc/apt/sources.list.d/dotnetdev.list'
sudo apt-get update

sudo sh -c 'echo "deb [arch=amd64] https://packages.microsoft.com/repos/microsoft-ubuntu-xenial-prod xenial main" > /etc/apt/sources.list.d/dotnetdev.list'
sudo apt-get update

3. Install

sudo apt-get install azure-functions-core-tools

Code and test Azure Functions locally

NOTE: npm can be used on all platforms. On unix platforms, you may need to specify --unsafe-perm if you are running npm with sudo. That's due to npm behavior of post install script.

NOTE: If you're running the v2 on Windows, Linux, or Mac, make sure to enable the beta runtime in function app settings, otherwise you may not see the same results as running locally.

func extensions command require the dotnet cli to be installed and on your path. This requirement is tracked here. You can install .NET Core for your platform from https://www.microsoft.com/net/download/

• CurrentDirectory: is the default directory the functions runtime looks for functions in.
• %TMP%\LogFiles\Application\Functions: is the default directory for logs. It mirrors the logs directory on Azure as well.
