This repo is a companion repo to the Automate Terraform with GitHub Actions.

1. Authentication

   • run aws configure from your terminal configure your user with the aws credentials

2. Building you Infrastructure on AWS

   • Create the *** terraform-and-aws *** folder
   • cd into the folder and run the command, wget https://raw.githubusercontent.com/linuxacademy/content-terraform-2021/main/main_aws.tf -O main.tf to download the terraform config file into a new file named main.tf
   • run terraform init to initialize terraform.
   • run terraform fmt to ensure your config file is well formatted
   • check the validity by running terraform validate
   • run terraform apply to provision the infrastructure
   • run terraform show to show the current state file or terraform state list to show all resources you are managing

3. Defining Input variables

   • run echo "# variable file" >> variables.tf to create the variable file
   • copy and paste the variable block into your variables file and save
   • go to the main.tf and replace the Name in the tag block with var.instance_name
   • then run terraform apply -var "instance_name=Chimezdev-cloudguru" to make changes

4. Using Output variables to query data

   • run wget https://raw.githubusercontent.com/linuxacademy/content-terraform-2021/main/outputs_aws.tf -O outputs.tf while in your working dir. to download the file into a file named outputs.tf
   • when the apply command completes you should see some outputs returned in the terminal, or run terraform output to see the ouputs displayed.
   • run terraform destroy to deprovision your infrastructure

5. Storing Remote State

   We will be using Terraform Cloud as our remote backend

   • run vim main.tf to edit the file using vim or any other text editor you prefer
   • add the following backend block to the terraform block

       backend "remote" {
           organization = "cloudguru-cicd-demo"
           workspaces {
               name= "cicd-project"
           }
       }
   

   • run terraform login and enter yes at the prompt to open terraform cloud on your browser.
   • click on create api token and copy the token and paste into your terminal.
   • now run terraform init to initialize the remote backend
   • you can now remove the state file store locally by running rm terraform.tfstate
   • head back to your browser and visit your terraform cloud page and add your aws credentials as environment variables.
   • when done go to the terminal and run terraform apply
