A Vault swiss-army knife: a K8s operator, Go client with automatic token renewal, automatic configuration, multiple unseal options and more. A CLI tool to init, unseal and configure Vault (auth methods, secret engines). Direct secret injection into Pods.

Bank Vaults is a thick, tricky, shifty right with a fast and intense tube for experienced surfers only, located on Mentawai. Think heavy steel doors, secret unlocking combinations and burly guards with smack-down attitude. Watch out for clean-up sets.

Bank-Vaults is an umbrella project which provides various tools for Vault to make using and operating Hashicorp Vault easier. Its a wrapper for the official Vault client with automatic token renewal and built in Kubernetes support, dynamic database credential provider for Golang SQL based clients. It has a CLI tool to automatically initialize, unseal and configure Vault. It also provides a Kubernetes operator for provisioning, and a mutating webhook for injecting secrets.

Bank-Vaults is a core building block of the Banzai Cloud Pipeline platform. Some of the usage patterns are highlighted through these blog posts:

Securing Kubernetes deployments with Vault:

• Authentication and authorization of Pipeline users with OAuth2 and Vault
• Dynamic credentials with Vault using Kubernetes Service Accounts
• Dynamic SSH with Vault and Pipeline
• Secure Kubernetes Deployments with Vault and Pipeline
• Vault Operator
• Vault unseal flow with KMS
• Monitoring Vault on Kubernetes using Cloud Native technologies
• Inject secrets directly into pods from Vault
• Backing up Vault with Velero
• Vault replication across multiple datacenters on Kubernetes

We use Vault across our large Kubernetes deployments and all the projects were reinventing the wheel. We have externalized all the codebase into this project and removed all the Pipeline and Hollowtrees dependencies thus this project can be used independently as a CLI tool to manage Vault, a Golang library to build upon (OAuth2 tokens, K8s auth, Vault operator, dynamic secrets, cloud credential storage, etc), Helm chart for a HA cluster, operator, mutating webhook and a collection of scripts to support some advanced features (dynamic SSH, etc).

We take bank-vaults' security and our users' trust very seriously. If you believe you have found a security issue in bank-vaults, please contact us at security@banzaicloud.com.

Bank-Vaults is a core part of Banzai Cloud Pipeline, a Cloud Native application and devops platform that natively supports multi- and hybrid-cloud deployments. Check out the developer beta:

Installing

You usually don’t need to use the CLI directly, rather you should install the charts and create Vault instances with the operator and use the webhook inside Kubernetes.

To grab the CLI binary go to the releases page and download it.

On macOs, you can directly Homebrew the CLI:

$ brew install banzaicloud/tap/bank-vaults

Alternatively, fetch the source and compile it using go get:

go get github.com/banzaicloud/bank-vaults/cmd/bank-vaults
go get github.com/banzaicloud/bank-vaults/cmd/vault-env
