tunnel

Open a TCP tunnel to a port inside the sandbox.

Creates a local TCP listener that forwards connections through a yamux-multiplexed WebSocket to the specified port inside the sandbox. Works with any TCP protocol (databases, Redis, HTTP, etc.).

Use as a context manager for automatic cleanup::

with sandbox.tunnel(remote_port=5432) as t:
    conn = psycopg2.connect(host="127.0.0.1", port=t.local_port)

Or manage the lifecycle explicitly::

t = sandbox.tunnel(remote_port=5432)
# ... use tunnel ...
t.close()
