action_run_python · action · Utility · Available · v1.1.0
Execute Python in an isolated Docker sandbox (512MB RAM, 1 CPU core, no privileges, read-only FS) with matplotlib/numpy/pandas/scipy/plotly/pillow/sympy/openpyxl available, plus requests/httpx when network is explicitly allowed. Output: stdout, stderr, exit code and generated files (charts, CSVs).
Fields shown in the editor when configuring the node. Generated directly from the NodeDefconfigFields.
| Field | Type | Required | Default | Description |
|---|---|---|---|---|
codeCodice Python | code | yes | import json, os
data = json.loads(os.environ.get("FLOWFORGE_INPUT", "{}"))
print({"received_keys": list(data.keys()), "count": len(data)})
| Codice Python. Input del nodo precedente disponibile in env var FLOWFORGE_INPUT (JSON string). Output stdout viene catturato e parsato come JSON se possibile, altrimenti tornato come stringa. Per output file (grafici/CSV) salva in cartella output/. Esempio: plt.savefig("output/chart.png"). Con allowNetwork=true: import requests; r=requests.get("https://api.esempio.it/x", timeout=10); print(r.json()). |
timeoutMsTimeout (ms) | number | no | 30000 | Tempo massimo esecuzione. Min 5000, max 120000. Default 30s. |
parseStdoutJsonParse stdout come JSON | boolean | no | true | Se on, prova a parsare stdout come JSON e ritorna l'oggetto strutturato. Se off o parsing fail, ritorna stdout come stringa. |
allowNetworkAbilita egress Internet (HTTP outbound) | boolean | no | false | OFF (default, raccomandato): nessun egress, sandbox massimamente isolata. ON (opt-in): il codice può chiamare API HTTP esterne (requests/httpx). SSRF block automatico verso cloud metadata (169.254.169.254) + RFC1918 + loopback + reti Docker interne. Ogni esecuzione con ON viene auditata nel log dedicato code-runner. Per task production-grade preferisci action_http_request (più ergonomico + circuit breaker per host). |
