# Vault proxy kubernetes persistent cache
|
|
|
|
When `kubernetes` is configured for the persistent cache type, Vault Proxy will optimize the
|
|
persistent cache specifically for Kubernetes. This type of persistent cache requires a Kubernetes
|
|
service account token. The service account token is used during encryption and decryption of the
|
|
persistent cache as an additional integrity check.
|
|
|
|
The Vault Proxy persistent cache file in Kubernetes should only be used for handing off Vault tokens
|
|
and leases between initialization and sidecar Vault Proxy containers. This cache file should be shared
|
|
using a memory volume between the Vault Proxy containers.
|
|
|
|
## Configuration
|
|
|
|
- `service_account_token_file` `(string: optional)` - When type is set to `kubernetes`,
|
|
this configures the path on disk where the Kubernetes service account token can be found.
|
|
Defaults to `/var/run/secrets/kubernetes.io/serviceaccount/token`.
