This Terraform module deploys a Kubernetes cluster on Azure using AKS (Azure Kubernetes Service) and adds support for monitoring with Log Analytics.
-> NOTE: If you have not assigned client_id or client_secret, A SystemAssigned identity will be created.

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

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)
}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 bashThen 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 fullWe 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.
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"Originally created by Damien Caro and Malte Lantin
