## aws-terraform-kubeAdm
In this repository, you can create kubernetes cluster using only `terraform apply` in AWS.
### 1. Configure on your docker
```bash
$ docker run -it graykode/aws-kubeadm-terraform:0.3 /bin/bash
```
Export your own AWS Access / Secret keys
```bash
$ export AWS_ACCESS_KEY_ID=
$ export AWS_SECRET_ACCESS_KEY=
```
Generate your SSH key pair for aws_key_pair
```bash
$ ssh-keygen -t rsa -N "" -f tf-kube
```
Create your `k8stoken`
```bash
$ python -c 'import random; print "%0x.%0x" % (random.SystemRandom().getrandbits(3*8), random.SystemRandom().getrandbits(8*8))'
> ebd70e.ad84c12d14ee5dae
```
### 2. Create Kubernetes Cluster
Initialize terraform
```bash
$ terraform init
```
Create all objects in AWS and put k8s token before you created! It's Done.
```bash
$ terraform apply
var.k8stoken
Enter a value: ebd70e.ad84c12d14ee5dae
```
Check if k8s Cluster is created.
```bash
$ ssh -i tf-kube ubuntu@server-ip
ubuntu@ip-10-43-0-40:~$ kubectl get nodes
NAME STATUS ROLES AGE VERSION
ip-10-43-0-30.ap-northeast-2.compute.internal Ready 3m40s v1.15.0
ip-10-43-0-40.ap-northeast-2.compute.internal Ready master 4m4s v1.15.0
```
If you want to delete all cluster, type this.
```bash
$ terraform destroy
```
#### If you want to see Kubernetes Clustering Step.
```bash
$ tail -f /home/ubuntu/master.log # in master node
$ tail -f /home/ubuntu/worker.log # in worker node
$ tail -f /home/ubuntu/etcd.log # in etcd node
```
### 3. Set [variables.tf](https://github.com/graykode/aws-kubeadm-terraform/blob/master/variables.tf)
1. Set EC2 instance_type
```javascript
variable etcd_instance_type {
default = "t2.medium"
}
variable controller_instance_type {
default = "t2.medium"
}
variable worker_instance_type {
default = "t2.medium"
}
```
2. Set Number of EC2 Node
```javascript
variable number_of_etcd{
description = "The number of etcd, only acts as etcd"
default = 0
}
variable number_of_worker{
description = "The number of worker nodes"
default = 1
}
```
#### PS
If you meet `provider.aws: error validating provider credentials` Error, Please check that your IAM key is activate.
#### ToDo
- Set up a High Availability etcd cluster with kubeadm
- Add k8s master node ingress, ingress-controller with ELB
