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
