Installation

From PyPI:

pip install geoservercloud

From git repository:

git clone https://github.com/camptocamp/python-geoservercloud
cd python-geoservercloud
python3 -m venv .venv
source .venv/bin/activate

Quick start

from geoservercloud import GeoServerCloud

geoserver = GeoServerCloud(
    url="http://localhost:9090/geoserver/cloud/",
    user="admin",
    password="geoserver",
)
geoserver.create_workspace("newworkspace")

About

Lightweight Python client to interact with GeoServer Cloud REST API, GeoServer ACL and OGC services. Intended use cases are listed below.

Programmatic setup of a GeoServer catalog

For example, creating a workspace, connecting to a PostGIS datastore and publishing a PG layer:

geoserver.create_workspace("example")
geoserver.create_pg_datastore(
    workspace_name="example",
    datastore_name="example_store",
    pg_host="localhost",
    pg_port=5432,
    pg_db="database",
    pg_user="user",
    pg_password="password"
)
geoserver.create_feature_type(
    layer_name="layer_example",
    workspace_name="example",
    datastore_name="example_store",
    title={
        "en":"Layer title",
        "fr": "Titre de la couche",
        "default": "Default title",
    },
)

Testing

Automatic tests of GeoServer functionalities with pytest, for example before upgrading. The example below tests the fallback mechanism for internationalized layer titles in the GetCapabilities document.

@pytest.mark.parametrize(
    "language,expected_title",
    [
        (
            "en",
            "Layer title",
        ),
        (
            "fr",
            "Titre de la couche",
        ),
        (
            "de,en",
            "Layer title",
        ),
        (
            None,
            "Default title",
        ),
    ],
)
def test_i18n_layer_title(geoserver, language, expected_title):
    capabilities = geoserver.get_wms_layers(
        workspace="example",
        accept_languages=language,
    )
    layer = capabilities.get("Layer")
    assert layer.get("Title") == expected_title

A test suite is provided in the directory geoserver_acceptance_tests.

Syncing

Copying a workspace from one GeoServer instance to another, including PG datastores, layers, styles and style images.

In a Python console or script

from geoservercloud import GeoServerCloudSync
geoserversync = GeoServerCloudSync(
    src_url="http://localhost:8080/geoserver",
    src_user="admin",
    src_password="geoserver",
    dst_url="http://localhost:9099/geoserver",
    dst_user="admin",
    dst_password="geoserver",
)
geoserversync.copy_workspace("workspace_name", deep_copy=True)

In a shell terminal or script

First install the package in your current virtual environment (see Installation), then run the script with:

copy-workspace --src_url "http://localhost:8080/geoserver" --src_user admin --src_password geoserver --dst_url "http://localhost:9099/geoserver" --dst_user admin --dst_password geoserver --workspace workspace_name

Logging

Set the log level using the standard logging module, e.g.:

import logging

gs_logger = logging.getLogger("geoservercloud")
gs_logger.setLevel(logging.DEBUG)
handler = logging.StreamHandler()
handler.setLevel(logging.DEBUG)
formatter = logging.Formatter("%(asctime)s - %(name)s - %(levelname)s - %(message)s")
handler.setFormatter(formatter)
gs_logger.addHandler(handler)
