Azure Key Vault to Kubernetes

Azure Key Vault to Kubernetes (akv2k8s) makes Azure Key Vault secrets, certificates and keys available to your applications in Kubernetes, in a simple and secure way.

Documentation available at https://akv2k8s.io. Join our Slack Workspace to ask questions to the akv2k8s community.

Overview

Azure Key Vault to Kubernetes (akv2k8s) will make Azure Key Vault objects available to Kubernetes in two ways:

As native Kubernetes Secrets
As environment variables directly injected into your Container application

The Azure Key Vault Controller (Controller for short) is responsible for synchronizing Secrets, Certificates and Keys from Azure Key Vault to native Secrets in Kubernetes.

The Azure Key Vault Env Injector (Env Injector for short) is responsible for transparently injecting Azure Key Vault secrets as environment variables into Container applications, without touching disk or exposing the actual secret to Kubernetes.

Goals

The goals for this project were:

Avoid a direct program dependency on Azure Key Vault for getting secrets, and adhere to the 12 Factor App principle for configuration (https://12factor.net/config)
Make it simple, secure and low risk to transfer Azure Key Vault secrets into Kubernetes as native Kubernetes secrets
Securely and transparently be able to inject Azure Key Vault secrets as environment variables to applications, without having to use native Kubernetes secrets

All of these goals are met.

Installation

For installation instructions, see documentation at https://akv2k8s.io/installation/.

Credits

Credit goes to Banzai Cloud for coming up with the original idea of environment injection for their bank-vaults solution, which they use to inject Hashicorp Vault secrets into Pods.
