AWS Minikube
AWS Minikube is a single node Kubernetes deployment in AWS. It creates an EC2 host and deploys the Kubernetes cluster using Kubeadm tool. It provides full integration with AWS. It is also able to handle ELB load balancers, EBS disks, Route53 domains and other AWS resources.

Prerequisites and Dependencies
AWS Minikube deploys into an existing VPC / public subnet. If you don't have your VPC / subnet yet, you can use this configuration 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
kubeconfigand access the cluster). To deploy AWS Minikube there are no other dependencies apart from Terraform. Kubeadm is used only on the EC2 host and doesn't have to be installed locally.
Configuration
The configuration is done through Terraform variables. Example tfvars file is part of this repo and is named example.tfvars. Change the variables to match your environment / requirements before running terraform apply ....
| Option | Explanation | Example |
|---|---|---|
aws_region |
AWS region which should be used | eu-central-1 |
cluster_name |
Name of the Kubernetes cluster (also used to name different AWS resources) | my-minikube |
aws_instance_type |
AWS EC2 instance type | t2.medium |
ssh_public_key |
SSH key to connect to the remote machine | ~/.ssh/id_rsa.pub |
aws_subnet_id |
Subnet ID where Minikube should run | subnet-8d3407e5 |
ami_image_id |
ID of the AMI image which should be used. If empty, the latest CentOS 7 image will be used. See README.md for AMI image requirements. |
ami-b81dbfc5 |
hosted_zone |
DNS zone which should be used | my-domain.com |
hosted_zone_private |
Is the DNS zone public or private | false |
addons |
List of add-ons which should be installed | [ "https://raw.githubusercontent.com/scholzj/aws-minikube/master/addons//storage-class.yaml" ] |
tags |
Tags which should be applied to all resources | { Hello = "World" } |
ssh_access_cidr |
Network CIDR from which SSH access will be allowed | 0.0.0.0/0 |
api_access_cidr |
Network CIDR from which API access will be allowed | 0.0.0.0/0 |
Creating AWS Minikube
To create AWS Minikube,
- Export AWS credentials into environment variables
AWS_ACCESS_KEY_IDandAWS_SECRET_ACCESS_KEY - Apply Terraform configuration:
terraform apply --var-file example.tfvarsDeleting AWS Minikube
To delete AWS Minikube,
- Export AWS credentials into environment variables
AWS_ACCESS_KEY_IDandAWS_SECRET_ACCESS_KEY - Destroy Terraform configuration:
terraform destroy --var-file example.tfvarsUsing 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
- Ingress
The add-ons will be installed automatically based on the Terraform variables.
Custom Add-ons
Custom add-ons can be added if needed. From every URL in the addons list, the initialization scripts will automatically call kubectl -f apply <Addon URL> 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.
Frequently Asked Questions
How to access Kubernetes Dashboard
The Kubernetes Dashboard add-on is by default not exposed to the internet. This is intentional for security reasons (no authentication / authorization) and to save costs for Amazon AWS ELB load balancer.
You can access the dashboard easily fro any computer with installed and configured kubectl:
- From command line start
kubectl proxy - Go to your browser and open http://127.0.0.1:8001/ui
