Initial Configuration
Before running the provisioning command, make sure to follow these initial steps.
Remote state backend on AWS S3 bucket
Create an S3 bucket that will be used to store the remote state backend for Terraform
aws s3api create-bucket --bucket <bucket-name> --region <region> --create-bucket-configuration LocationConstraint=<region>
Enable bucket versioning on the s3 bucket you have just created.
aws s3api put-bucket-versioning --bucket <bucket-name> --versioning-configuration Status=Enabled
Create sensitive.tfvars file
Your root and child Terraform files are set up to read any sensitive variable values from a file called sensitive.tfvars at the root directory. This file is not committed to the Git repo. The contents of the file can be as follows:
credentials="~/.aws/credentials"
profile="default"
public_key_location="~/.ssh/id_rsa.pub"
private_key_location="~/.ssh/id_rsa"
my_ip=<your-local-machine-ip>
Provision Infrastructure
Once you've completed all the above steps in the initial configuration, redirect to the root directory and run the following commands:
terraform init
terraform plan --var-file=sensitive.tfvars
terraform apply --var-file=sensitive.tfvars --auto-approve
