# Workflow: Deploy Hyperledger Bevel's HYPERLEDGER-FABRIC DLT Platform to an EKS Cluster.

# Prerequisites:
# 1. An accessible EKS Cluster
# 2. A Vault instance accessible from GitHub Runner
# 3. A completed network.yaml file stored in GitHub Secrets

# Workflow Overview:
# 1. This GitHub Actions workflow automates the seamless deployment of "BEVEL's HYPERLEDGER-FABRIC" platform to an EKS cluster.
# 2. Utilizing secure environment variables, the workflow manages sensitive information related to AWS, Docker, Cluster, Vault, and Git.
# 3. The workflow dynamically customizes a network configuration file by substituting placeholders with values derived from environment variables.
# 4. It uses tool Ansible to deploy the platform.
