Bug Reports

Describe the Bug

I am developing inside Docker containers on a remote server using the anysphere.remote-containers extension. When attempting to attach to a running container via the command Dev Containers: Attach to Running Container, the operation fails with the following error:

Command 'Dev Containers: Attach to Running Container' resulted in an error
command 'remote-containers.attachToRunningContainer' not found

Environment Details:

  • Containers are confirmed operational (docker ps shows multiple running containers).

  • Extension installed: anysphere.remote-containers

  • Full list of installed extensions (as requested):

Request:
Please investigate why the command remote-containers.attachToRunningContainer is unavailable despite the extension being installed and containers running normally.

Steps to Reproduce

Uninstalled and reinstalled Cursor.
Reinstalled the anysphere.remote-containers extension.
Result: Issue persists.

Expected Behavior

I want to develop inside docker containers

Hi @excited-tiger and @AltarIbnL , could you share the full logs from the “Remote - SSH” and “Remote - Dev Containers” output windows so we can take a closer look? Thanks!
