Terraform module for Azure FunctionApp ⚡️

Deploy a function app on Azure with minimal configuration

Features

• Create resource group, storage account and service plan automatically
• Use name for all created resources by default, allowing custom values to be defined
• Automatically set up deployment via local git repo and expose as git_url output
• By default deactivate client_affinity and activate always_on (dedicated plans only)
• Single parameter to start app in consumption plan plan_type = consumption
• Customize all the things ✨

Usage

🚨 Note: As Terraform and ARM do not natively support enabling local git deployment this module uses the az CLI for that. This means you need to have az installed and a valid login token when running Terraform. If you set git_enabled = false you do not need either.

Deploy a function app in consumption plan with git deployment enabled:

module "myfunction" {
    source              = "anoff/functionapp/azurerm"
    name                = "myfunction"
    location            = "westeurope"
    plan_type           = "consumption"
}

Outputs:
git_url = myfunction.scm.azurewebsites:net:443/myfunction.git
name    = myfunction
id      = /subscriptions/00000000-0000-0000-0000-000000000000/resourceGroups/mygroup1/providers/Microsoft.Web/sites/myfunction
outbound_ip_addresses = 52.23.25.3,52.143.43.12
default_hostname = myfunction.azurewebsites.net

Use a dedicated app plan with default settings and disabled git deployment:

module "myfunction" {
    source              = "anoff/functionapp/azurerm"
    location            = "westeurope"
    resource_group_name = "myresourcegroup"
    name                = "myfunction"
    plan_type           = "dedicated"
    git_enabled         = false
}

Outputs:
git_url = 
name    = myfunction
id      = /subscriptions/00000000-0000-0000-0000-000000000000/resourceGroups/mygroup1/providers/Microsoft.Web/sites/myfunction
outbound_ip_addresses = 52.23.25.3,52.143.43.12
default_hostname = myfunction.azurewebsites.net

Custom dedicated plan with web sockets:

module "myfunction" {
    source              = "anoff/functionapp/azurerm"
    location            = "westeurope"
    resource_group_name = "myresourcegroup"
    name                = "myfunction"
    plan_type           = "dedicated"
    plan_settings {
        kind     = "Windows" # Linux or Windows
        size     = "S3"
        capacity = 4
    }
    site_config {
        always_on          = true
        websockets_enabled = true
    }
}
