【한글자막】 DevOps(데브옵스): Terraform 을 이용한 AWS 인프라 자동화 2025

Introduction to what terraform is.

An alternative installation procedure using Vagrant. This will allow you to use exactly the same setup I have!

First steps in terraform: learn how to spin up your first instance. First: AWS account setup.

Summary of the first steps in terraform

An introduction to AWS VPCs (Virtual Private Cloud) - Part 1

An introduction to AWS VPCs (Virtual Private Cloud) - Part 2

An introduction to AWS VPCs (Virtual Private Cloud) - Part 3

A demo showing you how to launch a VPC with an internet gateway and a NAT gateway

Now that we have created our VPC, we can launch EC2 instances in the VPC

This is a demo showing you how to launch instances within a VPC

This lecture shows you how to use EBS (Elastic Block Storage) with an instance

This demo shows you how to attach EBS volumes to EC2 instances

Userdata can be used to execute commands at launch time

In this demo userdata will be used to format and mount an EBS volume if no filesystem is present. This way EBS volumes can be persisted in an automated way when the instance needs replacement.

This lecture explains the difference between private static IPs, EIPs and DNS (Route53)

This demo shows how to use Route53 to create DNS zones in AWS

This lecture explains how to spin up an RDS (relational database service) instance with terraform on AWS

In this demo I will spin up an RDS instance (using RDS subnets, RDS parameter groups, and security groups) and will connect from an EC2 instance to MariaDB..

IAM stands for Identity & Access Management. In this lecture I explain the different possibilities for access management. I explain users, groups, policies, and roles.

In this demo I create a group with an AWS group policy and attach it to a user.

IAM roles can be used to assume (temporary) access. In this lecture I explain how this works.

IAM roles can be used to assume (temporary) access. In this lecture I show you how to attach a role to an EC2 instance that will give permissions to read/write to an S3 bucket.

A lecture explaining how to setup autoscaling in AWS using terraform

A demo of autoscaling using terraform on AWS

Introduction into Elastic Load Balancers and Application Load Balancers in AWS

This lecture explains how to use ELBs in terraform with a static list of instances and an autoscaling group

A demo showing how to use terraform with an ELB together with autoscaling

An introduction of how the Application Load Balancer (ALB) works in terraform

ElasticBeanstalk (AWS's PaaS solution) setup using Terraform

ElasticBeanstalk (AWS's PaaS solution) setup demo using Terraform

Since terraform 0.12 you can use loops with for and for each. This lecture explains how and when to use for/foreach

For loops demo in terraform

For-each loops demo in terraform

The terraform providers lock file was introduced in terraform 0.14 and will from now on keep track of your provider and module dependency versions.

Terraform uses a state file (local / remote) that you can list resources of, read, and manipulate

Demo showing how to manipulate the state file in terraform

With packer AMIs can be created that can be used to launch an EC2 instance.

Where does Terraform fit in the DevOps organization? In this lecture I show you an example workflow with terraform, packer and jenkins

Packer can be integrated with terraform. This workflow shows how to create a workflow where packer creates the AMI and terraform launches the EC2 instance with the correct AMI ID

This demo shows a full cycle of an app in github, the building of a custom AMI with packer in Jenkins and the provisioning and deployment with Terraform

This demo shows a full cycle of an app in github, the building of a custom AMI with packer in Jenkins and the provisioning and deployment with Terraform

This lectures gives an introduction of Docker

This lecture explains how to use Docker on AWS using terraform

This lecture shows how to build docker images that can be pushed on ECR

In this demo I show how to push a docker built image to ECR

This lecture explains part I of the setup of ECS using terraform, with autoscaling and IAM roles

This lecture explains part II of the setup of ECS using terraform, with autoscaling, IAM roles, ECS task definitions and ECS Service definitions

This demo shows you how to run the pushed NodeJS app on ECS

In this demo I show you how to run a Jenkins workflow to build docker images, push the image to ECR, and use terraform to update ECS with the latest docker image

What features were released in terraform 0.12 and 0.13 to allow us to do more advanced module development?

This lectures explains what the difference between count and for_each is in terraform

This demo explains how to use the flatten() function with complex data types.
