aws-terraform-kubeAdm
In this repository, you can create kubernetes cluster using only terraform apply in AWS.
1. Configure on your docker
$ docker run -it graykode/aws-kubeadm-terraform:0.3 /bin/bashExport your own AWS Access / Secret keys
$ export AWS_ACCESS_KEY_ID=<Your Access Key in AWS>
$ export AWS_SECRET_ACCESS_KEY=<Your Access Key in Secret>Generate your SSH key pair for aws_key_pair
$ ssh-keygen -t rsa -N "" -f tf-kubeCreate your k8stoken
$ python -c 'import random; print "%0x.%0x" % (random.SystemRandom().getrandbits(3*8), random.SystemRandom().getrandbits(8*8))'
> ebd70e.ad84c12d14ee5dae2. Create Kubernetes Cluster
Initialize terraform
$ terraform init Create all objects in AWS and put k8s token before you created! It's Done.
$ terraform apply
var.k8stoken
Enter a value: ebd70e.ad84c12d14ee5daeCheck if k8s Cluster is created.
$ ssh -i tf-kube ubuntu@server-ip
ubuntu@ip-10-43-0-40:~$ kubectl get nodes

$ terraform destroyIf you want to see Kubernetes Clustering Step.
$ 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 node3. Set variables.tf
- Set EC2 instance_type
variable etcd_instance_type {
default = "t2.medium"
}
variable controller_instance_type {
default = "t2.medium"
}
variable worker_instance_type {
default = "t2.medium"
}- Set Number of EC2 Node
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
