# Vault agent persistent caching
|
|
|
|
Vault Agent can restore tokens and leases from a persistent cache file created
|
|
by a previous Vault Agent process. The persistent cache is a BoltDB file that
|
|
includes tuples encrypted by a generated encryption key. The encrypted tuples
|
|
include the Vault token used to retrieve secrets, leases for tokens/secrets, and
|
|
secret values.
|
|
|
|
-> **Note:** Vault Agent Persistent Caching will only restore _leased_
|
|
secrets. Secrets that are not renewable, such as KV v2, will not be persisted.
|
|
|
|
In order to use Vault Agent persistent cache, auto-auth must be used. If the
|
|
auto-auth token has expired by the time the cache is restored, the cache will
|
|
be invalidated and secrets will need to be re-fetched from Vault.
|
|
|
|
If Vault Agent templating is enabled alongside of the persistent cache, Vault
|
|
Agent will automatically route templating requests through the cache. This
|
|
ensures template requests are cached and restored properly.
|
|
|
|
-> **Note** Vault Agent persistent cache is currently supported only in a
|
|
Kubernetes environment.
|
