Litecoin Terraform

Terraform infrastructure for the Litecoin container project.

Usage

All Terraform operations should be done inside the Terraform container to ensure Terraform version stability:

# Start up the container:
bin/docker-run.sh

# Select workspace
tf workspace select litecoin

# Initialize modules and providers
tf init environments/litecoin

# Apply changes
tf apply environments/litecoin

State management

For now the state is local, normally the state would be placed to some remote backend (e.g. AWS S3 + DynamoDB).

Prerequisites

• Terraform expects AWS credentials, and some other data provided, e.g., in secret.auto.tfvars:

  AWS_ACCESS_KEY = 
  AWS_SECRET_KEY = 
  AWS_ACCOUNT_ID = 
  LITECOIN_DATA_ROOT= <host path for PV data>
  

• k8s-resources module assumes local Docker desktop Kubernetes cluster.
• k8s-resources module expects litecoin.conf file with credentials in resources/secret/ folder.

Modules

• aws-ecr creates ECR repositories,
• aws-eks stub module for EKS cluster provisioning,
• aws-iam-default creates related IAM entities (role, group, policy, user) in a unified fashion,
• aws-iam-technical creates technical IAM accounts (ci for ECR push and terraform for provisioning) with access keys as output for further usage,
• k8s-resource provisions necessary resources (NS, PV, secret) for the litecoin container deployment.
