Back-end Dev - Kubernetes/Docker - Azure KeyVault - Ethereum

Hello,

We have a back-end service that interacts with the Ethereum blockchain and signs transactions via a private key stored on the file system.

To increase security we would like to use Azure Key Vault HSM to prevent accidental leak of the private key. To accomplish this, we need a service running in Docker and Kubernetes that will receive transaction signing requests and would forward them to Azure Key Vault for signing. The service will need to be configured to use Kubernetes RBAC and Azure Service Principle to be properly authorized to forward requests to Azure Key Vault.
