Secret information management
|
|
=============================
|
|
|
|
The secrets driver in libvirt provides a simple interface for storing and
|
|
retrieving secret information.
|
|
|
|
Connections to SECRET driver
|
|
----------------------------
|
|
|
|
The libvirt SECRET driver is a multi-instance driver, providing a single system
|
|
wide privileged driver (the "system" instance), and per-user unprivileged
|
|
drivers (the "session" instance). A connection to the secret driver is
|
|
automatically available when opening a connection to one of the stateful primary
|
|
hypervisor drivers. It is none the less also possible to explicitly open just
|
|
the secret driver, using the URI protocol "secret" Some example connection URIs
|
|
for the driver are:
|
|
|
|
::
|
|
|
|
secret:///session (local access to per-user instance)
|
|
secret+unix:///session (local access to per-user instance)
|
|
|
|
secret:///system (local access to system instance)
|
|
secret+unix:///system (local access to system instance)
|
|
secret://example.com/system (remote access, TLS/x509)
|
|
secret+tcp://example.com/system (remote access, SASl/Kerberos)
|
|
secret+ssh://root@example.com/system (remote access, SSH tunnelled)
|
|
|
|
Embedded driver
|
|
~~~~~~~~~~~~~~~
|
|
|
|
Since 6.1.0 the secret driver has experimental support for operating in an
|
|
embedded mode. In this scenario, rather than connecting to the libvirtd daemon,
|
|
the secret driver runs in the client application process directly. To open the
|
|
driver in embedded mode the app use the new URI path and specify a virtual root
|
|
directory under which the driver will create content.
|
|
|
|
::
|
|
|
|
secret:///embed?root=/some/dir
|
|
|
|
Under the specified root directory the following locations will be used
|
|
|
|
::
|
|
|
|
/some/dir
|
|
|
|
|
+- etc
|
|
| |
|
|
| +- secrets
|
|
|
|
|
+- run
|
|
|
|
|
+- secrets
|
|
|
|
The application is responsible for recursively purging the contents of this
|
|
directory tree once they no longer require a connection, though it can also be
|
|
left intact for reuse when opening a future connection.
|
|
|
|
The range of functionality is intended to be on a par with that seen when using
|
|
the traditional system or session libvirt connections to QEMU. Normal practice
|
|
would be to open the secret driver in embedded mode any time one of the other
|
|
drivers is opened in embedded mode so that the two drivers can interact
|
|
in-process.
