render-lab-tasks-e2b

Twelve E2B sandbox lifecycle, execution, filesystem, logs, and metrics tasks. Wrapped tasks and raw injectable implementations live in render_lab_tasks_e2b.tasks. The root does not register tasks or read credentials.

Environment

E2B_API_KEY is required lazily. E2B_API_URL optionally overrides the control-plane API and logs endpoint. The adapter defaults E2B_CONNECTION_RETRIES to 0 before loading the SDK. If your application imports E2B independently, set that variable to 0 before starting the process; the adapter rejects an SDK already initialized with retries. The SDK versions are pinned because this setting is captured at import.

Behavior and verification

Create finds running or paused sandboxes by caller idempotency key. Pause, resume, and kill use the official async SDK. Task timeout fields stay in milliseconds and are converted to SDK seconds. Nonzero command exits return their exit code/output. Code, text, binary, and collection results use explicit limits. File metadata is checked before reading, then the stream is checked again and closed on overflow. No file is written onto the workflow host. Execution result text shares one budget, and the complete code result is capped at 4 MB. See ADR-0017 for stricter bounds.

Source fixtures compare all twelve tasks and SDK arguments independently with TS. Additional tests cover file growth and SDK retry configuration. Live sandbox tests remain pending an E2B account and disposable sandbox resources.
