Bank-Vaults

Bank-Vaults is an open-source toolkit for automating, operating, and securing HashiCorp Vault on Kubernetes and in cloud-native environments (secrets management, security automation).

  • Kubernetes operator and tools for deploying and managing Vault clusters (infrastructure automation, secrets management).
  • Automatic configuration, unsealing, and lifecycle management of Vault instances (security automation, secrets management).
  • Sidecar and mutating webhook components for injecting secrets into applications running on Kubernetes (application security, secrets delivery).
  • Integration with external secret backends and cloud-native platforms as supported by Vault and Kubernetes (secrets management, cloud integration).
  • Command-line utilities and libraries for managing Vault, configuring policies, and supporting GitOps workflows (DevOps tooling, configuration management).

More About Bank-Vaults

Bank-Vaults is an open-source project focused on automating and simplifying the operation of HashiCorp Vault (secrets management) in Kubernetes and cloud-native environments. It targets platform engineering, security, and Site Reliability Engineering (SRE) teams that need to run Vault in a repeatable, automated fashion, integrated with container orchestration platforms.

The project provides a Kubernetes Operator (infrastructure automation) that manages the full lifecycle of Vault clusters. This includes provisioning Vault instances, handling storage backends through Kubernetes resources, configuring HA settings, and managing upgrades. The operator relies on Kubernetes custom resource definitions (CRDs) to describe Vault deployments declaratively, enabling GitOps-style workflows where Vault configuration is stored and versioned alongside other cluster manifests.

Bank-Vaults also includes automation for Vault initialization and unsealing (security automation). It supports workflows where Vault is automatically initialized on first deployment and unseal keys are stored in external key management systems or cloud Key Management System (KMS) services, depending on the configuration supported by Vault and Kubernetes integrations. This reduces manual handling of unseal keys and supports automated recovery and rolling restarts of Vault pods within a cluster.

For application integration, Bank-Vaults provides a mutating admission webhook and sidecar pattern (application security). These components can inject a Vault agent or helper container into application pods and manage the delivery of secrets to workloads. Secrets can be exposed to applications through environment variables or files, depending on Kubernetes and Vault capabilities, which allows teams to decouple secret retrieval from application code while enforcing centralized policies in Vault.

The project offers command-line tools and libraries (DevOps tooling) that interact with Vault and Kubernetes APIs. These tools help create and template Vault configuration files, manage Vault policies and roles, and support configuration-as-code practices. They are designed to integrate into Continuous Integration and Continuous Deployment (CI/CD) pipelines and GitOps workflows so that Vault configuration, policies, and secret engines can be managed declaratively.

Bank-Vaults operates within the cloud-native ecosystem (cloud-native tooling) and is associated with the Cloud Native Computing Foundation (CNCF). It aligns with Kubernetes resource models, admission webhooks, and operators, and interoperates with Vault’s Hypertext Transfer Protocol (HTTP) APIs, authentication methods, and secret engines as configured by users. For enterprises, Bank-Vaults fits into categories such as secrets management enablement, Kubernetes platform security, and infrastructure automation, providing mechanisms to standardize how Vault is deployed, configured, and consumed across clusters and environments.
