terraform-azurerm-aks

Deploys a Kubernetes cluster on AKS with monitoring support through Azure Log Analytics

This Terraform module deploys a Kubernetes cluster on Azure using AKS (Azure Kubernetes Service) and adds support for monitoring with Log Analytics.

Usage

provider "azurerm" {
  features {}
}

resource "azurerm_resource_group" "example" {
  name     = "ask-resource-group"
  location = "eastus"
}

module "aks" {
  source              = "Azure/aks/azurerm"
  resource_group_name = azurerm_resource_group.example.name
  client_id           = "your-service-principal-client-appid"
  client_secret       = "your-service-principal-client-password"
  prefix              = "prefix"
}

The module supports some outputs that may be used to configure a kubernetes provider after deploying an AKS cluster.

provider "kubernetes" {
  host                   = module.aks.host
  client_certificate     = base64decode(module.aks.client_certificate)
  client_key             = base64decode(module.aks.client_key)
  cluster_ca_certificate = base64decode(module.aks.cluster_ca_certificate)
}

Test

Configurations

Configure Terraform for Azure

We provide 2 ways to build, run, and test the module on a local development machine. Native (Mac/Linux) or Docker.

Native (Mac/Linux)

Prerequisites

Environment setup

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

Run test

Then simply run it in local shell:

$ cd $GOPATH/src/{directory_name}/
$ bundle install

# set service principal
$ export ARM_CLIENT_ID="service-principal-client-id"
$ export ARM_CLIENT_SECRET="service-principal-client-secret"
$ export ARM_SUBSCRIPTION_ID="subscription-id"
$ export ARM_TENANT_ID="tenant-id"
$ export ARM_TEST_LOCATION="eastus"
$ export ARM_TEST_LOCATION_ALT="eastus2"
$ export ARM_TEST_LOCATION_ALT2="westus"

# set aks variables
$ export TF_VAR_client_id="service-principal-client-id"
$ export TF_VAR_client_secret="service-principal-client-secret"

# run test
$ rake build
$ rake full

Docker

We provide a Dockerfile to build a new image based FROM the mcr.microsoft.com/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.

Prerequisites

Docker

Custom Image

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-aks .

This runs the build and unit tests:

$ docker run --rm azure-aks /bin/bash -c "bundle install && rake build"

This runs the end to end tests:

$ docker run --rm azure-aks /bin/bash -c "bundle install && rake e2e"

This runs the full tests:

$ docker run --rm azure-aks /bin/bash -c "bundle install && rake full"
