This should also assist in auditing secret usage of each application. For example, you likely want to restrict a Pod to only access the secrets they need to function correctly. Pod authentication through Kubernetes Service Account for Vault Policy enforcement.For example, a web application that is using dynamic secrets to connect to a database with an expiring lease. Init container to fetch secrets before an application starts, and a Sidecar container that starts alongside your application for keeping secrets fresh (sidecar periodically checks to ensure secrets are current). For example, a backup job that runs on a regular schedule and only needs an initial secret at start time. Init only container to pre-populate secrets before an application starts.This is powered by a new tool called vault-k8s, which leverages the Kubernetes Mutating Admission Webhook to intercept and augment specifically annotated pod configuration for secrets injection using Init and Sidecar containers.Īpplications need only concern themselves with finding a secret at a filesystem path, rather than managing tokens, connecting to an external API, or other mechanisms for direct interaction with Vault. We are excited to announce a new Kubernetes integration that enables applications with no native HashiCorp Vault logic built-in to leverage static and dynamic secrets sourced from Vault.
