App Discovery and Management - DAPI

For basic app search and details, see Apps. This page covers advanced patterns.

Working with App Data as DataFrames¶

from dapi import DSClient
import pandas as pd

ds = DSClient()

all_apps = ds.apps.find("", verbose=False)

app_data = []
for app in all_apps:
    app_data.append(
        {
            "id": app.id,
            "version": app.version,
            "owner": app.owner,
            "execution_system": getattr(app.jobAttributes, "execSystemId", "N/A"),
            "max_minutes": getattr(app.jobAttributes, "maxMinutes", "N/A"),
            "cores_per_node": getattr(app.jobAttributes, "coresPerNode", "N/A"),
        }
    )

apps_df = pd.DataFrame(app_data)
print(apps_df.head())

Accessing the Raw Tapis Client¶

If you need Tapis APIs not wrapped by dapi, use the underlying client:

tapis_client = ds.tapis

# Get raw app details
raw_app = tapis_client.apps.getApp(appId="opensees-express")

# List apps with custom parameters
raw_apps = tapis_client.apps.getApps(search="*mpm*", listType="ALL")

# Access other Tapis services
systems = tapis_client.systems.getSystems()

Use ds.tapis when you need advanced search parameters, experimental Tapis features, or APIs not yet exposed by dapi.
