# terraform-eks-msf
[](https://registry.terraform.io/modules/mbiomee/eks/msf/)
General aws eks deploy using Terraform
---
## for more info
- [Amazon Elastic Kubernetes Service](https://aws.amazon.com/eks/)
- [Terraform](https://www.terraform.io/)
## Caution
applying this infrastructure will create resources on your aws account so be sure you have enough credits
to see resources [click here](https://registry.terraform.io/modules/mbiomee/eks/msf/?tab=resources)
## Prerequisites
1. aws account
2. IAM role with AdminstratorAccess policy
3. machine with aws cli, terraform cli, kubectl installed
4. create ssh key and upload the public key to your EC2 region
## Usage
create main.tf file and pass your variables link example
```terraform
module "eks" {
source = "mbiomee/eks/msf"
aws-region = "us-east-1"
availability-zones = ["us-east-1a", "us-east-1b", "us-east-1c"]
cluster-name = "msf-cluster"
k8s-version = "1.13"
node-instance-type = "t3.medium"
root-block-size = "40"
desired-capacity = "3"
max-size = "5"
min-size = "1"
public-min-size = "1"
public-max-size = "1"
public-desired-capacity = "1"
vpc-subnet-cidr = "10.0.0.0/16"
private-subnet-cidr = ["10.0.0.0/19", "10.0.32.0/19", "10.0.64.0/19"]
public-subnet-cidr = ["10.0.128.0/20", "10.0.144.0/20", "10.0.160.0/20"]
db-subnet-cidr = ["10.0.192.0/21", "10.0.200.0/21", "10.0.208.0/21"]
eks-cw-logging = ["api", "audit", "authenticator", "controllerManager", "scheduler"]
ec2-key = "my-key"
}
output "kubeconfig" {
value = module.eks.kubeconfig
}
output "config-map" {
value = module.eks.config-map
}
```
**Or** by using variables.tf or a tfvars file:
```terraform
module "eks" {
source = "mbiomee/eks/msf"
aws-region = var.aws-region
availability-zones = var.availability-zones
cluster-name = var.cluster-name
k8s-version = var.k8s-version
node-instance-type = var.node-instance-type
root-block-size = var.root-block-size
desired-capacity = var.desired-capacity
max-size = var.max-size
min-size = var.min-size
public-min-size = var.public-min-size
public-max-size = var.public-max-size
public-desired-capacity = var.public-desired-capacity
vpc-subnet-cidr = var.vpc-subnet-cidr
private-subnet-cidr = var.private-subnet-cidr
public-subnet-cidr = var.public-subnet-cidr
db-subnet-cidr = var.db-subnet-cidr
eks-cw-logging = var.eks-cw-logging
ec2-key = var.ec2-key
}
```
### Terraform
You need to run the following commands to create the resources with Terraform:
```bash
terraform init
terraform plan
terraform apply
```
### Setup kubectl
Setup your `KUBECONFIG`
```bash
terraform output kubeconfig > ~/.kube/eks-cluster
export KUBECONFIG=~/.kube/eks-cluster
```
### Authorize worker nodes
Get the config from terraform output, and save it to a yaml file:
```bash
terraform output config-map > config-map-aws-auth.yaml
```
Apply the config map to EKS:
```bash
kubectl apply -f config-map-aws-auth.yaml
```
You can verify the worker nodes are joining the cluster
```bash
kubectl get nodes --watch
```
### Cleaning up
You can destroy this cluster entirely by running:
```bash
terraform plan -destroy
terraform destroy --force
```
