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.
Please be aware that major version(e.g., from 6.8.0 to 7.0.0) update contains breaking changes that may impact your infrastructure. It is crucial to review these changes with caution before proceeding with the upgrade.
In most cases, you will need to adjust your Terraform code to accommodate the changes introduced in the new major version. We strongly recommend reviewing the changelog and migration guide to understand the modifications and ensure a smooth transition.
To help you in this process, we have provided detailed documentation on the breaking changes, new features, and any deprecated functionalities. Please take the time to read through these resources to avoid any potential issues or disruptions to your infrastructure.
- Notice on Upgrade to v9.x
- Notice on Upgrade to v8.x
- Notice on Upgrade to v7.x
- Notice on Upgrade to v6.x
- Notice on Upgrade to v5.x
Remember, upgrading to a major version with breaking changes should be done carefully and thoroughly tested in your environment. If you have any questions or concerns, please don't hesitate to reach out to our support team for assistance.
Please view folders in examples
.
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)
}
There're some examples in the examples folder. You can execute terraform apply
command in examples
's sub folder to try the module. These examples are tested against every PR with the E2E Test.
We're using BridgeCrew Yor and yorbox to help manage tags consistently across infrastructure as code (IaC) frameworks. In this module you might see tags like:
resource "azurerm_resource_group" "rg" {
location = "eastus"
name = random_pet.name
tags = merge(var.tags, (/*<box>*/ (var.tracing_tags_enabled ? { for k, v in /*</box>*/ {
avm_git_commit = "3077cc6d0b70e29b6e106b3ab98cee6740c916f6"
avm_git_file = "main.tf"
avm_git_last_modified_at = "2023-05-05 08:57:54"
avm_git_org = "lonegunmanb"
avm_git_repo = "terraform-yor-tag-test-module"
avm_yor_trace = "a0425718-c57d-401c-a7d5-f3d88b2551a4"
} /*<box>*/ : replace(k, "avm_", var.tracing_tags_prefix) => v } : {}) /*</box>*/))
}
To enable tracing tags, set the variable to true:
module "example" {
source = "{module_source}"
...
tracing_tags_enabled = true
}
The tracing_tags_enabled
is default to false
.
To customize the prefix for your tracing tags, set the tracing_tags_prefix
variable value in your Terraform configuration:
module "example" {
source = "{module_source}"
...
tracing_tags_prefix = "custom_prefix_"
}
The actual applied tags would be:
{
custom_prefix_git_commit = "3077cc6d0b70e29b6e106b3ab98cee6740c916f6"
custom_prefix_git_file = "main.tf"
custom_prefix_git_last_modified_at = "2023-05-05 08:57:54"
custom_prefix_git_org = "lonegunmanb"
custom_prefix_git_repo = "terraform-yor-tag-test-module"
custom_prefix_yor_trace = "a0425718-c57d-401c-a7d5-f3d88b2551a4"
}
We assumed that you have setup service principal's credentials in your environment variables like below:
export ARM_SUBSCRIPTION_ID="<azure_subscription_id>"
export ARM_TENANT_ID="<azure_subscription_tenant_id>"
export ARM_CLIENT_ID="<service_principal_appid>"
export ARM_CLIENT_SECRET="<service_principal_password>"
On Windows Powershell:
$env:ARM_SUBSCRIPTION_ID="<azure_subscription_id>"
$env:ARM_TENANT_ID="<azure_subscription_tenant_id>"
$env:ARM_CLIENT_ID="<service_principal_appid>"
$env:ARM_CLIENT_SECRET="<service_principal_password>"
We provide a docker image to run the pre-commit checks and tests for you: mcr.microsoft.com/azterraform:latest
To run the pre-commit task, we can run the following command:
$ docker run --rm -v $(pwd):/src -w /src mcr.microsoft.com/azterraform:latest make pre-commit
On Windows Powershell:
$ docker run --rm -v ${pwd}:/src -w /src mcr.microsoft.com/azterraform:latest make pre-commit
In pre-commit task, we will:
- Run
terraform fmt -recursive
command for your Terraform code. - Run
terrafmt fmt -f
command for markdown files and go code files to ensure that the Terraform code embedded in these files are well formatted. - Run
go mod tidy
andgo mod vendor
for test folder to ensure that all the dependencies have been synced. - Run
gofmt
for all go code files. - Run
gofumpt
for all go code files. - Run
terraform-docs
onREADME.md
file, then runmarkdown-table-formatter
to format markdown tables inREADME.md
.
Then we can run the pr-check task to check whether our code meets our pipeline's requirement(We strongly recommend you run the following command before you commit):
$ docker run --rm -v $(pwd):/src -w /src mcr.microsoft.com/azterraform:latest make pr-check
On Windows Powershell:
$ docker run --rm -v ${pwd}:/src -w /src mcr.microsoft.com/azterraform:latest make pr-check
To run the e2e-test, we can run the following command:
docker run --rm -v $(pwd):/src -w /src -e ARM_SUBSCRIPTION_ID -e ARM_TENANT_ID -e ARM_CLIENT_ID -e ARM_CLIENT_SECRET mcr.microsoft.com/azterraform:latest make e2e-test
On Windows Powershell:
docker run --rm -v ${pwd}:/src -w /src -e ARM_SUBSCRIPTION_ID -e ARM_TENANT_ID -e ARM_CLIENT_ID -e ARM_CLIENT_SECRET mcr.microsoft.com/azterraform:latest make e2e-test
To follow Ensure AKS uses disk encryption set policy we've used azurerm_key_vault
in example codes, and to follow Key vault does not allow firewall rules settings we've limited the ip cidr on it's network_acls
. By default we'll use the ip returned by https://api.ipify.org?format=json
api as your public ip, but in case you need to use another cidr, you can set an environment variable like below:
docker run --rm -v $(pwd):/src -w /src -e TF_VAR_key_vault_firewall_bypass_ip_cidr="<your_cidr>" -e ARM_SUBSCRIPTION_ID -e ARM_TENANT_ID -e ARM_CLIENT_ID -e ARM_CLIENT_SECRET mcr.microsoft.com/azterraform:latest make e2e-test
On Windows Powershell:
docker run --rm -v ${pwd}:/src -w /src -e TF_VAR_key_vault_firewall_bypass_ip_cidr="<your_cidr>" -e ARM_SUBSCRIPTION_ID -e ARM_TENANT_ID -e ARM_CLIENT_ID -e ARM_CLIENT_SECRET mcr.microsoft.com/azterraform:latest make e2e-test
