**How to Use:**
- Export the variables for your AWS credentials or edit credentials.tfvars:
- Export the variables for your AWS credentials or edit `credentials.tfvars`:
```
export aws_access_key="xxx"
export aws_secret_key="yyy"
export aws_ssh_key_name="zzz"
export AWS_ACCESS_KEY_ID="www"
export AWS_SECRET_ACCESS_KEY ="xxx"
export AWS_SSH_KEY_NAME="yyy"
export AWS_DEFAULT_REGION="zzz"
```
- Rename `contrib/terraform/aws/terraform.tfvars.example` to `terraform.tfvars`
- Update contrib/terraform/aws/terraform.tfvars with your data
- Update `contrib/terraform/aws/terraform.tfvars` with your data
- Allocate new AWS Elastic IPs: Depending on # of Availability Zones used (2 for each AZ)
- Create an AWS EC2 SSH Key
- Run with `terraform apply -var-file="credentials.tfvars"` or `terraform apply` depending if you exported your AWS credentials
- Run with `terraform apply --var-file="credentials.tfvars"` or `terraform apply` depending if you exported your AWS credentials
- Terraform automatically creates an Ansible Inventory file called `hosts` with the created infrastructure in the directory `inventory`
- Once the infrastructure is created, you can run the kargo playbooks and supply inventory/hosts with the `-i` flag.
**Troubleshooting**
***Remaining AWS IAM Instance Profile***:
If the cluster was destroyed without using Terraform it is possible that
the AWS IAM Instance Profiles still remain. To delete them you can use
the `AWS CLI` with the following command:
```
aws iam delete-instance-profile --region <region_name> --instance-profile-name <profile_name>
```
***Ansible Inventory doesnt get created:***
It could happen that Terraform doesnt create an Ansible Inventory file automatically. If this is the case copy the output after `inventory=` and create a file named `hosts`in the directory `inventory` and paste the inventory into the file.
**Architecture**
Pictured is an AWS Infrastructure created with this Terraform project distributed over two Availability Zones.
