`Import/Export Servers`:index:
|
|
******************************
|
|
|
|
Server definitions (and their groups) can be exported to a JSON file and
|
|
re-imported to the same or a different system to enable easy pre-configuration
|
|
of pgAdmin. The ``setup.py`` script is used for this purpose.
|
|
|
|
.. note:: To export or import servers, you must use the Python interpreter that
|
|
is normally used to run pgAdmin to ensure that the required Python
|
|
packages are available. In most packages, this can be found in the
|
|
Python Virtual Environment that can be found in the installation
|
|
directory. When using platform-native packages, the system installation
|
|
of Python may be the one used by pgAdmin.
|
|
|
|
Exporting Servers
|
|
*****************
|
|
|
|
To export the servers defined in an installation, simply invoke ``setup.py`` with
|
|
the ``--dump-servers`` command line option, followed by the name (and if required,
|
|
path) to the desired output file. By default, servers owned by the desktop mode
|
|
user will be dumped (pgadmin4@pgadmin.org by default - see the DESKTOP_USER
|
|
setting in ``config.py``). This can be overridden with the ``--user`` command
|
|
line option. For example:
|
|
|
|
.. code-block:: bash
|
|
|
|
/path/to/python /path/to/setup.py --dump-servers output_file.json
|
|
|
|
# or, to specify a non-default user name:
|
|
|
|
/path/to/python /path/to/setup.py --dump-servers output_file.json --user user@example.com
|
|
|
|
To export only certain servers, use the ``--servers`` option and list one or
|
|
more server IDs. For example:
|
|
|
|
.. code-block:: bash
|
|
|
|
/path/to/python /path/to/setup.py --dump-servers output_file.json --server 1 2 5
|
|
|
|
Importing Servers
|
|
*****************
|
|
|
|
To import the servers defined in a JSON file, simply invoke ``setup.py`` with
|
|
the ``--load-servers`` command line option, followed by the name (and if required,
|
|
path) of the JSON file containing the server definitions. Servers will be owned
|
|
by the desktop mode user (pgadmin4@pgadmin.org by default - see the DESKTOP_USER
|
|
setting in ``config.py``). This can be overridden with the ``--user`` command
|
|
line option. For example:
|
|
|
|
.. code-block:: bash
|
|
|
|
/path/to/python /path/to/setup.py --load-servers input_file.json
|
|
|
|
# or, to specify a non-default user name to own the new servers:
|
|
|
|
/path/to/python /path/to/setup.py --load-servers input_file.json --user user@example.com
|
|
|
|
If any Servers are defined with a Server Group that is not already present in
|
|
the configuration database, the required Group will be created.
|
|
|
|
JSON format
|
|
***********
|
|
|
|
The JSON file format used when importing or exporting servers is quite
|
|
straightforward and simply contains a list of servers, with a number of
|
|
attributes. The following attributes are required to be present in every server
|
|
definition: Name, Group, Port, Username, SSLMode, MaintenanceDB and one of Host,
|
|
HostAddr or Service.
|
|
|
|
Password fields cannot be imported or exported.
|
|
|
|
The following example shows both a minimally defined and a fully defined server:

|
|
|
