## Control plane details
### ServiceAccount controller
A ServiceAccount controller manages the ServiceAccounts inside namespaces, and
ensures a ServiceAccount named "default" exists in every active namespace.
### Token controller
The service account token controller runs as part of `kube-controller-manager`.
This controller acts asynchronously. It:
- watches for ServiceAccount creation and creates a corresponding
ServiceAccount token Secret to allow API access.
- watches for ServiceAccount deletion and deletes all corresponding ServiceAccount
token Secrets.
- watches for ServiceAccount token Secret addition, and ensures the referenced
ServiceAccount exists, and adds a token to the Secret if needed.
- watches for Secret deletion and removes a reference from the corresponding
ServiceAccount if needed.
You must pass a service account private key file to the token controller in
the `kube-controller-manager` using the `--service-account-private-key-file`
flag. The private key is used to sign generated service account tokens.
Similarly, you must pass the corresponding public key to the `kube-apiserver`
using the `--service-account-key-file` flag. The public key will be used to
verify the tokens during authentication.
