# AWS Minikube Terraform module



AWS Minikube is a single node Kubernetes deployment in AWS. It creates EC2 host and deploys Kubernetes cluster using [Kubeadm](https://kubernetes.io/docs/admin/kubeadm/) tool. It provides full integration with AWS. It is able to handle ELB load balancers, EBS disks, Route53 domains etc.

## Prerequisites and dependencies



* AWS Minikube deploys into existing VPC / public subnet. If you don't have your VPC / subnet yet, you can use [this](https://github.com/scholzj/aws-vpc) configuration or [this](https://github.com/scholzj/terraform-aws-vpc) module to create one.

  * The VPC / subnet should be properly linked with Internet Gateway (IGW) and should have DNS and DHCP enabled.

  * Hosted DNS zone configured in Route53 (in case the zone is private you have to use IP address to copy `kubeconfig` and access the cluster).

* To deploy AWS Minikube there are no other dependencies apart from [Terraform](https://www.terraform.io). Kubeadm is used only on the EC2 host and doesn't have to be installed locally.



## Including the module



Although it can be run on its own, the main value is that it can be included into another Terraform configuration.



```hcl

module "minikube" {

  source = "github.com/scholzj/terraform-aws-minikube"



  aws_region    = "eu-central-1"

  cluster_name  = "my-minikube"

  aws_instance_type = "t2.medium"

  ssh_public_key = "~/.ssh/id_rsa.pub"

  aws_subnet_id = "subnet-8a3517f8"

  ami_image_id = "ami-b81dbfc5"

  hosted_zone = "my-domain.com"

  hosted_zone_private = false



  tags = {

    Application = "Minikube"

  }



  addons = [

    "https://raw.githubusercontent.com/scholzj/terraform-aws-minikube/master/addons/storage-class.yaml",

    "https://raw.githubusercontent.com/scholzj/terraform-aws-minikube/master/addons/heapster.yaml",

    "https://raw.githubusercontent.com/scholzj/terraform-aws-minikube/master/addons/dashboard.yaml",

    "https://raw.githubusercontent.com/scholzj/terraform-aws-minikube/master/addons/external-dns.yaml"

  ]

}

```



An example of how to include this can be found in the [examples](examples/) dir. 



## Using custom AMI Image



AWS Minikube is built and tested on CentOS 7. But gives you the possibility to use their own AMI images. Your custom AMI image should be based on RPM distribution and should be similar to Cent OS 7. When `ami_image_id` variable is not specified, the latest available CentOS 7 image will be used.



## Add-ons



Currently, following add-ons are supported:

* Kubernetes dashboard

* Heapster for resource monitoring

* Storage class and CSI driver for automatic provisioning of persistent volumes

* External DNS (Replaces Route53 mapper)

* Ingress



The add-ons will be installed automatically based on the Terraform variables. 



## Custom add-ons



Custom add-ons can be added if needed. Fro every URL in the `addons` list, the initialization scripts will automatically call `kubectl -f apply ` to deploy it. Minikube is using RBAC. So the custom add-ons have to be *RBAC ready*.



## Tagging



If you need to tag resources created by your Kubernetes cluster (EBS volumes, ELB load balancers etc.) check [this AWS Lambda function which can do the tagging](https://github.com/scholzj/aws-kubernetes-tagging-lambda).



## Kubernetes version



The intent for this module is to use it for development and testing against the latest version of Kubernetes. As such, the primary goal for this module is to ensure it works with whatever is the latest version of Kubernetes supported by Minikube. This includes provisioning the cluster as well as setting up networking and any of the [supported add-ons](#add-ons). This module might, but is not guaranteed to, also work with other versions of Kubernetes. At your own discretion, you can use the `kubernetes_version` variable to specify a different version of Kubernetes for the Minikube cluster.
