The VPC for the developer, at its simplest, boils down to naming a subnet as a specific resource.

Let's write the configuration according to the documentation www.terraform.io/docs/providers/aws/r/eks_cluster. html :

esschtolts @ cloudshell: ~ / terraform / aws (agile-aleph-203917) $ cat main.tf

provider "aws" {

access_key = "$ {var.token}"

secret_key = "$ {var.key}"

region = "us-east-1"

}

# Params

variable "token" {

default = ""

}

variable "key" {

default = ""

}

# EKS

resource "aws_eks_cluster" "example" {

enabled_cluster_log_types = ["api", "audit"]

name = "exapmle"

role_arn = "arn: aws: iam :: 177510963163: role / ServiceRoleForAmazonEKS2"

vpc_config {

subnet_ids = ["$ {aws_subnet.subnet_1.id}", "$ {aws_subnet.subnet_2.id}"]

}

}

output "endpoint" {

value = "$ {aws_eks_cluster.example.endpoint}"

}

output "kubeconfig-certificate-authority-data" {

value = "$ {aws_eks_cluster.example.certificate_authority.0.data}"

}

# Role

data "aws_iam_policy_document" "eks-role-policy" {

statement {

actions = ["sts: AssumeRole"]

principals {

type = "Service"

identifiers = ["eks.amazonaws.com"]

}

}

}

resource "aws_iam_role" "tf_role" {

name = "tf_role"

assume_role_policy = "$ {data.aws_iam_policy_document.eks-role-policy.json}"

tags = {

tag-key = "tag-value"

}

}

resource "aws_iam_role_policy_attachment" "attach-cluster" {

role = "tf_role"

policy_arn = "arn: aws: iam :: aws: policy / AmazonEKSClusterPolicy"

}

resource "aws_iam_role_policy_attachment" "attach-service" {

role = "tf_role"

policy_arn = "arn: aws: iam :: aws: policy / AmazonEKSServicePolicy"

}

# Subnet

resource "aws_subnet" "subnet_1" {

vpc_id = "$ {aws_vpc.main.id}"

cidr_block = "10.0.1.0/24"

availability_zone = "us-east-1a"

tags = {

Name = "Main"

}

}

resource "aws_subnet" "subnet_2" {

vpc_id = "$ {aws_vpc.main.id}"

cidr_block = "10.0.2.0/24"

availability_zone = "us-east-1b"

tags = {

Name = "Main"

}

}

resource "aws_vpc" "main" {

cidr_block = "10.0.0.0/16"

}

After 9 minutes 44 seconds, I got a ready-made self-supporting infrastructure for a Kubernetes cluster:

esschtolts @ cloudshell: ~ / terraform / aws (agile-aleph-203917) $ ./../terraform apply -var = "token = AKIAJ4SYCNH2XVSHNN3A" -var = "key = huEWRslEluynCXBspsul3AkKlin1ViR9 + Mo

Now let's delete (it took me 10 minutes 23 seconds):

esschtolts @ cloudshell: ~ / terraform / aws (agile-aleph-203917) $ ./../terraform destroy -var = "token = AKIAJ4SYCNH2XVSHNN3A" -var = "key = huEWRslEluynCXBspsul3AkKlin1ViR9 + Mo

Destroy complete! Resources: 7 destroyed.

Establishing the CI / CD process

Amazon provides (aws.amazon.com/ru/devops/) a wide range of DevOps tools designed in a cloud infrastructure:

* AWS Code Pipeline – the service allows you to create a chain of stages from a set of services in a visual editor, through which the code must go before it goes to production, for example, assembly and testing.

* AWS Code Build – the service provides an auto-scaling build queue, which may be required for compiled programming languages, when adding features or making changes requires a long re-compilation of the entire application, when using one server it becomes a bottleneck when rolling out the changes.

* AWS Code Deploy – Automates deployment and rollback in case of errors.

* AWS CodeStar – the service combines the main features of the previous services.
