A terraform module to provide load balancers in Azure with the following characteristics:
- Ability to specify
public
orprivate
loadbalancer using:var.type
. Default is public. - Specify subnet to use for the loadbalancer:
frontend_subnet_id
- For
private
loadbalancer, specify the private ip address usingfrontend_private_ip_address
- Specify the type of the private ip address with
frontend_private_ip_address_allocation
, Dynamic or Static , default isDynamic
Public loadbalancer example:
provider "azurerm" {
features {}
}
resource "azurerm_resource_group" "example" {
name = "example-lb"
location = "West Europe"
}
module "mylb" {
source = "Azure/loadbalancer/azurerm"
resource_group_name = azurerm_resource_group.example.name
prefix = "terraform-test"
remote_port = {
ssh = ["Tcp", "22"]
}
lb_port = {
http = ["80", "Tcp", "80"]
}
lb_probe = {
http = ["Tcp", "80", ""]
}
depends_on = [azurerm_resource_group.example]
}

Private loadbalancer example:

features {}
}
resource "azurerm_resource_group" "example" {
name = "example-lb"
location = "West Europe"
}
module "mylb" {
source = "Azure/loadbalancer/azurerm"

type = "private"
frontend_subnet_id = module.network.vnet_subnets[0]
frontend_private_ip_address_allocation = "Static"
frontend_private_ip_address = "10.0.1.6"
lb_sku = "Standard"
pip_sku = "Standard" #`pip_sku` must match `lb_sku`
remote_port = {
ssh = ["Tcp", "22"]
}
lb_port = {
http = ["80", "Tcp", "80"]
https = ["443", "Tcp", "443"]
}
lb_probe = {
http = ["Tcp", "80", ""]
http2 = ["Http", "1443", "/"]
}
tags = {
cost-center = "12345"
source = "terraform"
}
}
module "network" {
source = "Azure/network/azurerm"
resource_group_name = azurerm_resource_group.example.name
address_space = "10.0.0.0/16"
subnet_prefixes = ["10.0.1.0/24", "10.0.2.0/24", "10.0.3.0/24"]
subnet_names = ["subnet1", "subnet2", "subnet3"]
tags = {
environment = "dev"
costcenter = "it"
}
}
We provide 2 ways to build, run, and test the module on a local development machine. Native (Mac/Linux) or Docker.
We provide simple script to quickly set up module development environment:
$ curl -sSL https://raw.githubusercontent.com/Azure/terramodtest/master/tool/env_setup.sh | sudo bash
Then simply run it in local shell:
$ cd $GOPATH/src/{directory_name}/
$ bundle install
$ rake build
$ rake e2e
We provide a Dockerfile to build a new image based FROM
the microsoft/terraform-test
Docker hub image which adds additional tools / packages specific for this module (see Custom Image section). Alternatively use only the microsoft/terraform-test
Docker hub image by using these instructions.
This builds the custom image:
$ docker build --build-arg BUILD_ARM_SUBSCRIPTION_ID=$ARM_SUBSCRIPTION_ID --build-arg BUILD_ARM_CLIENT_ID=$ARM_CLIENT_ID --build-arg BUILD_ARM_CLIENT_SECRET=$ARM_CLIENT_SECRET --build-arg BUILD_ARM_TENANT_ID=$ARM_TENANT_ID -t azure-loadbalancer .
This runs the build and unit tests:
$ docker run --rm azure-loadbalancer /bin/bash -c "bundle install && rake build"
This runs the end to end tests:
$ docker run --rm azure-loadbalancer /bin/bash -c "bundle install && rake e2e"
This runs the full tests:
$ docker run --rm azure-loadbalancer /bin/bash -c "bundle install && rake full"
