Vault + Kubernetes (vault-k8s)
vault-k8s binary includes first-class integrations between Vault and
Kubernetes. Currently the only integration in this repository is the
Vault Agent Sidecar Injector (
agent-inject). In the future more integrations
will be found here.
The Kubernetes integrations with Vault are documented directly on the Vault website. This README will present a basic overview of each use case, but for full documentation please reference the Vault website.
This project is versioned separately from Vault. Supported Vault versions for each feature will be noted below. By versioning this project separately, we can iterate on Kubernetes integrations more quickly and release new versions without forcing Vault users to do a full Vault upgrade.
- Agent Inject: Agent Inject is a mutation webhook controller that injects Vault Agent containers into pods meeting specific annotation criteria. (Requires Vault 1.3.1+)
vault-k8s is distributed in multiple forms:
The recommended installation method is the official Vault Helm chart. This will automatically configure the Vault and Kubernetes integration to run within an existing Kubernetes cluster.
A Docker image
hashicorp/vault-k8sis available. This can be used to manually run
vault-k8swithin a scheduled environment.
