Update VyOS
|
|
===========
|
|
|
|
New system images can be added using the :opcmd:`add system image`
|
|
command. The command will extract the chosen image and will prompt you
|
|
to use the current system configuration and SSH security keys, allowing
|
|
for the new image to boot using the current configuration.
|
|
|
|
.. note:: Only LTS releases are PGP-signed.
|
|
|
|
.. opcmd:: add system image <url | path> [vrf name] [username user [password pass]]
|
|
|
|
Use this command to install a new system image. You can reach the
|
|
image from the web (http://, https://) or from your local system,
|
|
e.g. /tmp/vyos-1.2.3-amd64.iso.
|
|
|
|
The `add system image` command also supports installing new versions
|
|
of VyOS through an optional given VRF. Also if URL in question requires
|
|
authentication, you can specify an optional username and password via
|
|
the commandline which will be passed as "Basic-Auth" to the server.
|
|
|
|
If there is not enough **free disk space available**, the installation
|
|
will be canceled. To delete images use the :opcmd:`delete system image`
|
|
command.
|
|
|
|
VyOS configuration is associated to each image, and **each image has a
|
|
unique copy of its configuration**. This is different than a traditional
|
|
network router where the configuration is shared across all images.
|
|
|
|
.. note:: If you have any personal files, like some scripts you created,
|
|
and you don't want them to be lost during the upgrade, make sure
|
|
those files are stored in ``/config`` as this directory is always copied
|
|
to newer installed images.
|
|
|
|
You can access files from a previous installation and copy them to your
|
|
current image if they were located in the ``/config`` directory. This
|
|
can be done using the :opcmd:`copy` command. So, for instance, in order
|
|
to copy ``/config/config.boot`` from VyOS 1.2.1 image, you would use the
|
|
following command:
|
|
|
|
.. code::
|
|
|
|
copy file 1.2.1://config/config.boot to /tmp/config.boot.1.2.1
|
|
|
|
