Vault is a popular Key Management Service (KMS) to manage and protect your sensitive data like tokens, passwords, certificates, encryption keys and other sensitive data.
In this tutorial, you will deploy a Vault instance to #OpenShift and enable authentication via #Kubernetes. You will deploy a Guestbook application and configure the application to access encrypted secrets from the internal Vault server instance using the Vault Agent Injector.
The Vault agent injector injects two sidecar containers: an init container that prepopulates a shared memory volume with the requested secrets and a sidecar container to authenticate and render secrets to the same location as the pod runs. The application accesses secrets via the shared memory volume.
