Custos AWS Deployment

Create the Deployment

Follow the instructions below to create the AWS deployment:

1. Navigate to airavata-custos/terraform/aws and run the terraform init command to initialize the Terraform workspace, which includes downloading the required Terraform modules and providers.
2. Run terraform plan to preview the infrastructure changes that Terraform plans to make based on the configuration files. This command allows you to review what will be created, updated, or destroyed.
3. Run terraform apply -auto-approve to execute the proposed changes and create the resources, including the state bucket and DynamoDB locking table. When this command is executed for the first time, the Terraform state will be stored locally. To migrate the Terraform state to AWS, run terraform init -force-copy only once after the resources are created.

Destroy the Deployment

To safely destroy the deployment, follow these steps:

1. Set the force_destroy parameter to true in the terraform_state_backend module within the main.tf file. This step is necessary to ensure the S3 state bucket can be deleted even if it contains objects.
2. Run terraform apply -target module.terraform_state_backend -auto-approve to apply this change, enabling the deletion of the S3 state bucket.
3. Run terraform init -force-copy to migrate the Terraform state from the S3 bucket back to local storage. This step prepares for a complete destruction of the infrastructure.
4. Finally, run terraform destroy -auto-approve to remove all resources defined in the Terraform configuration. This command deletes the deployment from AWS.
