Leveraging the Globus Platform

UCSD – May 8, 2019
Globus serves as…
A platform for building science
gateways, web portals and
other applications in support of
research and education
2
Example web apps that leverage Globus
3
Globus Auth
(identity and access management)
…
GlobusAPIs
(Transfer,Search,Identifiers,…)
GlobusConnect
Data Automation
File Sharing
File Transfer, Sync
Globus Platform-as-a-Service
Globus Auth addresses security challenges
• Make it easy for developers to provide login for
their apps (web, mobile, desktop, command line)
• …and protect all REST API communications
o App à Globus service (MRDP, Jupyter Notebook)
o App à non-Globus service (graph service in MRDP)
o Service à Service
• …while
– Not introducing yet another identity
– Providing a platform to consolidate existing identities
– Providing a least privileges security model (via consents)
– Being web friendly and language/framework agnostic
5
Based on widely used web standards
• OAuth 2.0 Authorization Framework (a.k.a. OAuth2)
• OpenID Connect Core 1.0 (a.k.a. OIDC)
• Access via OAuth2 and OIDC libraries of your choice
– Google OAuth Client Libraries, Apache mod_auth_openidc, etc.
– Globus Python SDK

Globus Platform
Transfer API
Globus Transfer API
• Globus Web App consumes public Transfer API
• REST API: Resources/actions named by URL
– Query params allow refinement (e.g., filter)
• Globus APIs use JSON for documents and resource
representations
• Requests authorized via Globus Auth issued OAuth2
access token
– Authorization: Bearer asdflkqhafsdafeawk
docs.globus.org/api/transfer
9
Globus Python SDK
• Python client library for the Globus Auth and Transfer
REST APIs
• globus_sdk.TransferClient class handles
connection management, security, framing,
marshaling
from globus_sdk import TransferClient
tc = TransferClient()
globus.github.io/globus-sdk-python
10
TransferClient low-level calls
• Thin wrapper around REST API
– post(), get(), update(), delete()
get(path, params=None, headers=None, auth=None,
response_class=None)
o path – path for the request, with or without leading slash
o params – dict to be encoded as a query string
o headers – dict of HTTP headers to add to the request
o response_class – class response object, overrides the client’s
default_response_class
o Returns: GlobusHTTPResponse object
11
TransferClient higher-level calls
• One method for each API resource and HTTP verb
• Largely direct mapping to REST API
endpoint_search(filter_fulltext=None,
filter_scope=None,
num_results=25,
**params)
12
Globus Helper Pages
• Globus pages designed for use by your web apps
– Browse Endpoint
– Activate Endpoint
– Select Group
– Manage Identities
– Manage Consents
– Logout
docs.globus.org/api/helper-pages
13
Example
Modern Research
Data Portal
https://docs.globus.org/modern-research-data-portal/
API walkthrough using Jupyter Notebook
• Use the Globus JupyterHub: jupyter.demo.globus.org
– Sign in with Globus and verify the consents
– Click “Start My Server” (this will take about a minute)
– Navigate to: globus-jupyter-notebooks à GlobusWorldTour
– Open Platform_Introduction_Native_App_Auth.ipynb
• If you misstep and want to start over…
– Close your notebook and navigate back to the root folder
– Open and run the NotebookPuller.ipynb notebook
• Access Globus notebooks outside of our JupyterHub:
github.com/globus/globus-jupyter-notebooks
15
Endpoint Search
• Plain text search for endpoint
– Searches owner, display name, keywords, description,
organization, department
– Full word and prefix match
• Limit search to pre-defined scopes
– all, my-endpoints, recently-used, in-use, shared-
by-me, shared-with-me
• Returns: List of endpoint documents
16
Endpoint Management
• Get endpoint (by id)
• Update endpoint
• Create & delete (shared) endpoints
• Manage endpoint servers
17
Endpoint Activation
• Activating endpoint means binding a credential to an
endpoint for login
• Server endpoints that have MyProxy or MyProxy
OAuth identity provider require login via web
• Auto-activate
– Globus Connect Personal and Shared endpoints use Globus-
provided credential
– Must auto-activate before any API calls to endpoints
18
File operations
• List directory contents (ls)
• Make directory (mkdir)
• Rename
• Note:
– Path encoding & UTF gotchas
– Don’t forget to auto-activate first
19
Task submission
• Asynchronous operations
– Transfer
o Sync level option
– Delete
• Get submission_id, followed by submit
– Once and only once submission
20
Task management
• Get task by id
• Get task_list
• Update task by id (label, deadline)
• Cancel task by id
• Get event list for task
• Get task pause info
21
Shared endpoints and access rules (ACL)
• Shared Endpoint – create / delete / get info / get list
• Administrator role required to delegate access managers
• Access manager role required to manage
permissions/ACL
• Operations:
– Get list of access rules
– Get access rule by id
– Create access rule
– Update access rule
– Delete access rule
22
Management API
• Allow endpoint administrators to monitor and manage
all tasks with endpoint
– Task API is essentially the same as for users
– Information limited to what they could see locally
• Cancel tasks
• Pause rules
