Terraform/AWS

• Task1 : Create EC2 instance using Terraform is located in aws.tf

• Task2 : Create VPC infrastracture then create two EC2 one is bastion (public subnet and inside the VPC) and private EC2, then try to access the private through the public ec2 (Hint: ssh -A arrgument) , find the image below:  

   

• Task3 : Improve the VPC terraform code with (resource naming (Local, Global), Variable, Count variable to reduce repeating code)

• Task4 : learn more about git commands, and how to solve conflict. bellow is the list of commands we discussed:

            * One: git rebase -i HEAD~7 - interactive rebase of last 7 commits then do git push --force
  
                      interactive rebase options:
                      1. p, pick <commit> = use commit
                      2. r, reword <commit> = use commit, but edit the commit message
                      3. e, edit <commit> = use commit, but stop for amending
                      4. s, squash <commit> = use commit, but meld into previous commit
                      5. d, drop <commit> = remove commit
  
            * Two: git commit --amend - instead of adding additional commit, amend the prvious one
  
            * Three: git rebase main - rebase your main branch, useful when you need to solve merge conflicts
  

• Task5 : Create two EC2 instance using Terraform and improve the code by using data.tf to get the availablity zones and AMI, and output.tf to export the instance public IP after creation

• Task6 : use userdata to install apache2, clone 2048 game from github and open port 80 to access the game from browser (http)

• Task7 : use remote state to store terraform state on S3 bucket

• Task8 : Create Layers for AWS infrastructure to encapsulate each layer

• Task9 : Automate remote backend by adding new layer to create both S3 bucket and dynamodb

• Task10 : Create load balancer

• Task11 : attach IAM role to EC2 instance

• Task12 : Create auto scalling group

• Task13 : use AWS SSM (Session Manager) instead of using boston instance

• Task14 : create modules for the main services.

• Task15 : Register domain using Route53 service and add SSL encryption

• Task16 : Create RDS MySQL database and use Amazon Secret Manager to store password

• Task17 : Practice Terraform Functions

• Task18 : Open Source Terraform modules

• Task19 : Build EKS cluster using terraform and Helm

• Task20 : Final project to deploy WordPress application using AWS, Docker, EKS, Terraform, Helm, GitHub
