Python Client and Girder CLI¶
In addition to the web clients, Girder comes with a python client library and a CLI to allow for programmatic interaction with a Girder server, and also to workaround limitations of the web client. For example, the python CLI makes it much easier to upload a large, nested hierarchy of data from a local directory to Girder, and also makes it much easier to download a large, nested hierarchy of data from Girder to a local directory.
Installation¶
If you have the source directory of Girder, you can find the girder_client
package within the clients/python
directory. If you do not have the source
directory of Girder, you can install the client via pip:
pip install girder-client
After installing the client via pip and if you are using bash
,
auto-completion can easily be enabled executing:
eval "$(_GIRDER_CLI_COMPLETE=source girder-client)"
For convenience, adding this line at the end of .bashrc
will make sure
auto-completion is always available.
For more details, see http://click.pocoo.org/6/bashcomplete/
The Command Line Interface¶
The girder_client package ships with a command-line utility that wraps some of
its common functionality to make it easy to invoke operations without having
to write any custom python scripts. If you have installed girder_client via
pip, you can use the girder-client
executable:
girder-client <arguments>
To see all available commands, run:
girder-client --help
For help with a specific command, run:
girder-client <command> --help
Specifying the Girder Instance¶
When constructing a Girder client, you must declare what instance of Girder
you wish to connect to. The easiest way to do so is to pass the full URL to the
REST API of the Girder instance you wish to connect to using the api-url
argument to girder-client
. For example:
girder-client --api-url http://localhost:8080/api/v1 <command> ...
Instead of using api-url
argument, you may also specify the URL in parts, using the
host
argument, and optional scheme
, port
, and api-root
args.
Specifying credentials¶
The recommended way is to generate an API key and specify
the api-key
argument.
girder-client --api-url https://girder.example.com:443/api/v1 --api-key abcdefghijklmopqrstuvwxyz012345678901234 ...
Setting the GIRDER_API_KEY
environment variable is also supported:
export GIRDER_API_KEY=abcdefghijklmopqrstuvwxyz012345678901234
girder-client --api-url https://girder.example.com:443/api/v1 ...
The client also supports username
and password
args. If only the
username
is specified, the client will prompt the user to interactively
input their password.
Disabling SSL verification¶
Specifying --no-ssl-verify
allows to ignore SSL verification. This is
usually required when using the client behind a proxy that is not configured to
accept the certificate of the given host.
Specifying a custom SSL certificate¶
Specifying --certificate /path/to/custom_bundle.pem
allows to use a custom “bundle” of
Certificate Authority (CA) public keys (CA certs) for performing the SSL verification
applied when the https
scheme is associated with the API url.
By default, the carefully curated collection of Root Certificates from Mozilla is used. See https://pypi.python.org/pypi/certifi
Upload a local file hierarchy¶
To upload a folder hierarchy rooted at test_folder to the Girder Folder with id 54b6d41a8926486c0cbca367
girder-client upload 54b6d41a8926486c0cbca367 test_folder
When using the upload command, the default --parent-type
, meaning the type
of resource the local folder will be created under in Girder, is Folder, so the
following are equivalent
girder-client upload 54b6d41a8926486c0cbca367 test_folder
girder-client upload 54b6d41a8926486c0cbca367 test_folder --parent-type folder
To upload that same local folder to a Collection or User, specify the parent type as follows
girder-client upload 54b6d41a8926486c0cbca459 test_folder --parent-type user
To see what local folders and files on disk would be uploaded without actually
uploading anything, add the --dry-run
flag
girder-client upload 54b6d41a8926486c0cbca367 test_folder --dry-run
To have leaf folders (those folders with no subfolders, only containing files)
be uploaded to Girder as single Items with multiple Files, i.e. those leaf
folders will be created as Items and all files within the leaf folders will be
Files within those Items, add the --leaf-folders-as-items
flag
girder-client upload 54b6d41a8926486c0cbca367 test_folder --leaf-folders-as-items
If you already have an existing Folder hierarchy in Girder which you have a
superset of on your local disk (e.g. you previously uploaded a hierarchy to
Girder and then added more folders and files to the hierarchy on disk), you can
reuse the existing hierarchy in Girder, which will not create new Folders and
Items for those that match folders and files on disk, by using the --reuse
flag.
girder-client upload 54b6d41a8926486c0cbca367 test_folder --reuse
To include a blacklist of file patterns that will not be uploaded, pass a comma
separated list to the --blacklist
arg
girder-client upload 54b6d41a8926486c0cbca367 test_folder --blacklist .DS_Store
Download a hierarchy of data into a local folder¶
Folder¶
To download a Girder Folder hierarchy rooted at Folder id 54b6d40b8926486c0cbca364 under the local folder download_folder
girder-client download 54b6d40b8926486c0cbca364 download_folder
Collection¶
To download the Girder Folder hierarchies associated with a Girder Collection with id 57b5c9e58d777f126827f5a1 under the local folder download_folder
girder-client download --parent-type collection 57b5c9e58d777f126827f5a1 download_folder
User¶
To download the Girder Folder hierarchies associated with a Girder User with id 54f8ac238d777f69813604af under the local folder download_folder
girder-client download --parent-type user 54b6d40b8926486c0cbca364 download_folder
Item¶
To download the file(s) associated with a Girder Item with if 58b8eb798d777f0aef5d0f78 under the local folder download_folder:
girder-client download --parent-type item 8b8eb798d777f0aef5d0f78 download_folder
File¶
To download a specific file from girder with id 58b8eb798d777f0aef5d0f78 to the local file local_file
girder-client download --parent-type file 8b8eb798d777f0aef5d0f78 local_file
Auto-detecting parent-type¶
Both download and upload commands accept a –parent-type argument allowing the users to specify the type (folder, collection, user, or item) associated with the chosen object id.
If the argument is omitted, the client will conveniently try to autodetect the type by iteratively invoking the resource/%id/path?type=%type API end point and checking if a resource is found.
Note that relying on auto-detection incurs extra network requests, which will slow down the script, so it should be avoided for time-sensitive operations.
Synchronize local folder with a Folder hierarchy¶
If the download_folder is a local copy of a Girder Folder hierarchy rooted at Folder id 54b6d40b8926486c0cbca364, any change made to the Girder Folder remotely can be synchronized locally by
girder-client localsync 54b6d40b8926486c0cbca364 download_folder
This will only download new Items or Items that have been modified since the last download/localsync. Local files that are no longer present in the remote Girder Folder will not be removed. This command relies on a presence of metadata file .metadata-girder within download_folder, which is created upon girder-client download. If .metadata-girder is not present, localsync will fallback to download.
The Python Client Library¶
For those wishing to write their own python scripts that interact with Girder, we recommend using the Girder python client library, documented below.
Recursively inherit access control to a Folder’s descendants¶
This will take the access control and public value in the Girder Folder with id 54b43e9b8926486c0c06cb4f and copy those to all of the descendant Folders
import girder_client
gc = girder_client.GirderClient(apiUrl='https://data.kitware.com/api/v1')
gc.authenticate('username', 'password')
gc.inheritAccessControlRecursive('54b43e9b8926486c0c06cb4f')
Set callbacks for Folder and Item uploads¶
If you have a function you would like called upon the completion of an Item or Folder upload, you would do the following.
N.B. The Item callbacks are called after the Item is created and all Files are uploaded to the Item. The Folder callbacks are called after the Folder is created and all child Folders and Items are uploaded to the Folder.
import girder_client
gc = girder_client.GirderClient()
def folderCallback(folder, filepath):
# assume we have a folderMetadata dict that has
# filepath: metadata_dict_for_folder
gc.addMetadataToFolder(folder['_id'], folderMetadata[filepath])
def itemCallback(item, filepath):
# assume we have an itemMetadata dict that has
# filepath: metadata_dict_for_item
gc.addMetadataToItem(item['_id'], itemMetadata[filepath])
gc.authenticate('username', 'password')
gc.addFolderUploadCallback(folderCallback)
gc.addItemUploadCallback(itemCallback)
gc.upload(localFolder, parentId)

client = GirderClient(apiUrl='http://myhost:8080') client.authenticate('myname', 'mypass') folder_id = '53b714308926486402ac5aba' item = client.createItem(folder_id, 'an item name', 'a description') client.addMetadataToItem(item['_id'], {'metadatakey': 'metadatavalue'}) client.uploadFileToItem(item['_id'], 'path/to/your/file.txt') r1 = client.getItem(item['_id']) r2 = client.sendRestRequest('GET', 'item', {'folderId': folder_id, 'sortdir': '-1' }) r3 = client.sendRestRequest('GET', 'resource/search', {'q': 'aggregated','types': '["folder", "item"]'})
-
__init__
(host=None, port=None, apiRoot=None, scheme=None, apiUrl=None, cacheSettings=None, progressReporterCls=None)[source]¶ Construct a new GirderClient object, given a host name and port number, as well as a username and password which will be used in all requests (HTTP Basic Auth). You can pass the URL in parts with the host, port, scheme, and apiRoot kwargs, or simply pass it in all as one URL with the apiUrl kwarg instead. If you pass apiUrl, the individual part kwargs will be ignored.
Parameters: - apiUrl – The full path to the REST API of a Girder instance, e.g. http://my.girder.com/api/v1.
- host – A string containing the host name where Girder is running, the default value is ‘localhost’
- port – The port number on which to connect to Girder, the default value is 80 for http: and 443 for https:
- apiRoot – The path on the server corresponding to the root of the Girder REST API. If None is passed, assumes ‘/api/v1’.
- scheme – A string containing the scheme for the Girder host, the default value is ‘http’; if you pass ‘https’ you likely want to pass 443 for the port
- cacheSettings – Settings to use with the diskcache library, or None to disable caching.
- progressReporterCls – the progress reporter class to instantiate. This class
is expected to be a context manager with a constructor accepting label and
length keyword arguments, an update method accepting a chunkSize argument and
a class attribute reportProgress set to True (It can conveniently be
initialized using sys.stdout.isatty()).
This defaults to
_NoopProgressReporter
.
-
addFolderUploadCallback
(callback)[source]¶ Saves a passed in callback function that will be called after each folder has completed. Multiple callback functions can be added, they will be called in the order they were added by calling this function. Callback functions will be called after a folder in Girder is created and all subfolders and items for that folder have completed uploading. Callback functions should take two parameters: - the folder in Girder - the full path to the local folder
Parameters: callback – callback function to be called.
-
addItemUploadCallback
(callback)[source]¶ Saves a passed in callback function that will be called after each item has completed. Multiple callback functions can be added, they will be called in the order they were added by calling this function. Callback functions will be called after an item in Girder is created and all files for that item have been uploaded. Callback functions should take two parameters: - the item in Girder - the full path to the local folder or file comprising the item
Parameters: callback – callback function to be called.
-
addMetadataToCollection
(collectionId, metadata)[source]¶ Takes a collection ID and a dictionary containing the metadata
Parameters: - collectionId – ID of the collection to set metadata on.
- metadata – dictionary of metadata to set on collection.

-
authenticate
(username=None, password=None, interactive=False, apiKey=None)[source]¶ Authenticate to Girder, storing the token that comes back to be used in future requests. This method can be used in two modes, either username and password authentication, or using an API key. Username example:
gc.authenticate(username='myname', password='mypass')
Note that you may also pass
interactive=True
and omit either the username or password argument to be prompted for them in the shell. The second mode is using an API key:API keys can be created and managed on your user account page in the Girder web client, and can be used to provide limited access to the Girder web API.
Parameters: - username – A string containing the username to use in basic authentication.
- password – A string containing the password to use in basic authentication.
- interactive – If you want the user to type their username or password in the shell rather than passing it in as an argument, set this to True. If you pass a username in interactive mode, the user will only be prompted for a password. This option only works in username/password mode, not API key mode.
- apiKey (str) – Pass this to use an API key instead of username/password authentication.

HttpError
(status, text, url, method, response=None)[source]¶ Raised if the server returns an error status code from a request. @deprecated This will be removed in a future release of Girder.
