- Export the variables for your AWS credentials or edit `credentials.tfvars`:

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.

Before running the cluster playbook you must satisfy the following requirements:
* On each CoreOS nodes a writable directory **/opt/bin** (~400M disk space)
General CoreOS Pre-Installation Notes:
- You should set the bootstrap_os variable to `coreos`
- Ensure that the bin_dir is set to `/opt/bin`
- ansible_python_interpreter should be `/opt/bin/python`. This will be laid down by the bootstrap task.
- The default resolvconf_mode setting of `docker_dns` **does not** work for CoreOS. This is because we do not edit the systemd service file for docker on CoreOS nodes. Instead, just use the `host_resolvconf` mode. It should work out of the box.
Then you can proceed to [cluster deployment](#run-deployment)

For all kube components, custom flags can be passed in. This allows for edge cases where users need changes to the default deployment that may not be applicable to all deployments. This can be done by providing a list of flags. Example:
```
kubelet_custom_flags:
- "--eviction-hard=memory.available<100Mi"
- "--eviction-soft-grace-period=memory.available=30s"
- "--eviction-soft=memory.available<300Mi"
