[zNeill]

Description

Description:

destroy sandbox will delete port 8080 and docker volume

Environment:- Platform: Spark + FastOS VERSION="1.120.38"

• NemoClaw: v0.0.7
• OpenClaw: 2026.3.11
• Sandbox: my-test

Steps to Reproduce:

1. Destroy to a healthy sandbox:

local-lynnh@p4242-0371:~$ nemoclaw list

  Sandboxes:
    my-test *
      model: openai/openai/gpt-5.4  provider: compatible-endpoint  GPU  policies: pypi, npm

  * = default sandbox

local-lynnh@p4242-0371:~$ sudo docker volume ls
DRIVER    VOLUME NAME
local     openshell-cluster-nemoclaw

local-lynnh@p4242-0371:~/caroline$ nemoclaw my-test destroy
Destroy sandbox 'my-test'? This cannot be undone. [y/N]: y

Stopping NIM for 'my-test'...

Stopping NIM container: nemoclaw-nim-my-test

Deleting sandbox 'my-test'...

! No active forward found for port 18789

• Destroying gateway nemoclaw...

✓ Gateway nemoclaw destroyed.

✓ Sandbox 'my-test' destroyed

2. Check the port 8080 and Docker volume

Actual:

Volume and Ports 8080/18789 are deleted

local-lynnh@p4242-0371:~$ sudo docker volume ls
DRIVER    VOLUME NAME

local-lynnh@p4242-0371:~$ sudo lsof -i :8080 -i :18789

If we have several sandboxes, destroy one of them, will lead to other sandboxes failed to connect

local-joychen@p4242-0079:~$ nemoclaw list

  Sandboxes:
    abc *
      model: gemini-2.5-flash  provider: gemini-api  GPU  policies: pypi
    lifecycle-test
      model: gemini-2.5-flash  provider: gemini-api  GPU  policies: none
    bcd
      model: gemini-2.5-flash  provider: gemini-api  GPU  policies: none
    lynn-test
      model: gemini-2.5-flash  provider: gemini-api  GPU  policies: none

  * = default sandbox

local-joychen@p4242-0079:~$ nemoclaw abc destroy
  Destroy sandbox 'abc'? This cannot be undone. [y/N]: y
  Stopping NIM for 'abc'...
  Stopping NIM container: nemoclaw-nim-abc
  Deleting sandbox 'abc'...
  ✓ Sandbox 'abc' destroyed
local-joychen@p4242-0079:~$ nemoclaw status abc

  Sandboxes:
    lifecycle-test * (gemini-2.5-flash)
    bcd (gemini-2.5-flash)
    lynn-test (gemini-2.5-flash)
