Geo servershell Geo servershell Presentation Transcript

  • Geoserver Shell Administer Geoserver using a CLI Jared Erickson CUGOS July 2013
  • Outline • What is Geoserver Shell? • Why does Geoserver need a CLI? • What are we administering with CLI? • How does it work? • What does it look like in action?
  • What is it? • Administer Geoserver from a command line interface (CLI) • Uses Geoserver Rest interface • Based on Spring Shell • Uses GeoServer Manager and GeoTools • Written in Java • Open Source MIT License • Hosted on Github
  • Why a CLI? • Web UI is a major feature • Non developers can load data and styles • CLI is quick, efficient and scriptable • Once a script is written it can be replayed on other Geoservers (set up dev, then test, then production)
  • Geoserver UI
  • Geoserver Catalog • Workspace • Namespace • DataStore • FeatureType • CoverageStore • Coverage • Layer • LayerGroups • Style • WMSStore
  • Geoserver Rest • • • • • Administer GeoServer without GUI • Integrate with 3rd party applications Multiple representations: HTML, JSON, XML HTTP Verbs: GET, POST, PUT, DELETE HATEOS - linking http://docs.geoserver.org/stable/en/user/rest/ index.html
  • Verbs Commands Verbs list GET get GET create POST modify PUT delete DELETE
  • Geoserver Rest UI
  • /geoserver/rest/layers
  • Client #1 = curl • Upload a Shapefile curl -v -u admin:geoserver -XPUT -H "Content-type: application/zip" --data-binary @roads.zip http://localhost:8080/geoserver/rest/workspaces/acme/datastores/roads/ file.shp • Create a Workspace curl -v -u admin:geoserver -XPOST -H "Content-type: text/xml" -d "<workspace><name>acme</name></workspace>" http://localhost:8080/geoserver/rest/ workspaces
  • Client #2 = Python • gsconfig.py • https://github.com/dwins/gsconfig.py/wiki • Used by GeoNode >>> from geoserver.catalog import Catalog >>> cat = Catalog("http://localhost:8080/geoserver/rest", "admin", "geoserver") >>> cat.get_layers() [Layer[Arc_Sample], Layer[Pk50095], Layer[Img_Sample], ... >>> that_layer = cat.get_layer("roads") >>> that_layer.enabled = False >>> cat.save(that_layer)
  • Client #3 = Java • Geoserver Manager Library • https://github.com/geosolutions-it/ geoserver-manager GeoServerRESTReader reader = new GeoServerRESTReader(url, user, password); RESTStyleList styleList = reader.getStyles(); List<String> names = styleList.getNames(); GeoServerRESTPublisher publisher = new GeoServerRESTPublisher(url, user, password); publisher.createWorkspace(name);
  • Github https://github.com/jericks/geoserver-shell
  • Install • Download 0.1 release • https://github.com/jericks/geoserver-shell/ releases • Put bin directory on path • run gs-shell • Requires Java
  • Spring Shell • Open source project from Spring Source • Shell extracted from Spring Roo • Spring Roo is a Java RAD tool for creating web apps
  • Spring Shell • Interactive shell environment • Tab completion for commands, arguments, and files • History support (up and down arrows) • Knows your commands and when you can use them
  • Geoserver Shell • Commands for each major Geoserver Catalog item • Methods in command construct a URL, create a request body (xml, file) and make an Http Request to Geoserver. The Geoserver response is parsed and displayed to the user
  • Commands geoserver datastore ows workspace shapefile settings version postgis gwc manifest featuretype wmsstore namespace coverage stores style coverage template worldimage font layers
  • Workspace Commands • workspace list • workspace create --name test • workspace get --name test • workspace delete --name test • workspace default get • workspace default set --name test
  • Workspace gs-shell> geoserver set --url http://localhost:8080/geoserver gs-shell> workspace create --name naturalearth true gs-shell> workspace list topp nurc gs-shell> workspace get --name naturalearth naturalearth
  • Shapefile gs-shell> geoserver set --url http://localhost:8080/geoserver gs-shell> workspace create --name naturalearth true gs-shell> shapefile zip --shapefile 110m_admin_0_countries.shp true gs-shell> shapefile publish --file 110m_admin_0_countries.zip -workspace naturalearth true
  • PostGIS gs-shell> geoserver set --url http://localhost:8080/geoserver gs-shell> workspace create --name post gs-shell> postgis datastore create --workspace post --datastore postgis -host localhost --port 5432 --database postgres --schema public --user postgres --password postgres true gs-shell> featuretype list --workspace post --datastore postgis --list available states countries cities gs-shell> postgis featuretype publish --workspace post --datastore postgis -table 110m-admin-0-countries true
  • GeoTiff gs-shell> geoserver set --url http://localhost:8080/geoserver gs-shell> coverage store upload --workspace naturalearth --file GRAY_50M_SR_OB.zip --coveragestore world --type worldimage -configure first true gs-shell> coverage list --workspace naturalearth --coveragestore world GRAY_50M_SR_OB BLUE_MARBLE gs-shell> coverage modify --workspace naturalearth --coveragestore world --coverage GRAY_50M_SR_OB --srs EPSG:4326 --enabled true true
  • Styles gs-shell> style create --file 110m_admin_0_countries.sld --name 110m_admin_0_countries true gs-shell> layer style add --name 110m_admin_0_countries --style 110m_admin_0_countries true gs-shell> layer get --name 110m_admin_0_countries 110m_admin_0_countries Title: null Type:VECTOR Abstract: null Default Style: 110m_admin_0_countries Namespace: Type String:VECTOR gs-shell> layer modify --name 110m_admin_0_countries --defaultStyle 110m_admin_0_countries true
  • Scripts • Scripts contain the same commands entered interactively • History support saves session to geoservershell.log $ gs-shell --cmdfile mycommands.gs gs-shell> script --file naturalearth_countries.gs
