Actual Behavior

We have some php development stacks that use a docker compose file. The code directory is mounted into the container using a bind mount.

volumes:
    - type: bind
      source: ./../
      target: /var/www

We edit code directly on the macOS host and rely upon these changes showing up in the container. In this case macOS is the source of truth. The one exception is running composer install from inside the container. In that case the container is making the file system changes and we rely on those being reflected back on the host. This scenario was working great in Rancher Desktop 0.7.1. Upon upgrading to 1.0.0 we immediately began seeing failures running composer install.

Plugin kylekatarnls/update-helper could not be initialized, class not found: UpdateHelper\ComposerPlugin

I could work around that specific issue by running composer global require kylekatarnls/update-helper . There was very strange behavior when running composer install afterward though. We would see each dependency show up in the vendor folder, then disappear, and then be replaced by a different dependency. When composer install had finished there was only a single dependency in the vendor folder.

---

Updating the override.yaml file to re-enable sshfs caching fixes the issue.

mounts:
- location: "~"
  sshfs:
    cache: true

With that change in place composer install correctly runs inside the container.

Steps to Reproduce

Setup rancher desktop 1.0.0.
Run composer install from inside of a host mounted directory.

Result

Files appear and disappear.

Expected Behavior

Composer install completes successfully with all files reflected on the host filesystem.

I have created a sample project here that reproduces the issue https://github.com/dschaaff/rancher-desktop-issue-1349

To reproduce

• ensure Rancher Desktop 1.0.0 is in dockerd mode and override.yml is empty
• install the docker-compose cli plugin if necessary
• clone https://github.com/dschaaff/rancher-desktop-issue-1349
• run docker-compose up -d
• exec into container docker-compose exec php bash
• run composer install
• observe the vendor folder in finder while the operation is running. you will see folders appearing and then disappearing
  Observe the error

root@0be843f86b29:/var/www# composer install
Loading composer repositories with package information
Installing dependencies (including require-dev) from lock file

  - Installing kylekatarnls/update-helper (1.2.1): Downloading (100%)
Plugin installation failed (Plugin kylekatarnls/update-helper could not be initialized, class not found: UpdateHelper\ComposerPlugin), rolling back
  - Removing kylekatarnls/update-helper (1.2.1)


  [UnexpectedValueException]
  Plugin kylekatarnls/update-helper could not be initialized, class not found: UpdateHelper\ComposerPlugin

• quit rancher desktop
• update override.yml to enable sshfs cache

mounts:
- location: "~"
  sshfs:
    cache: true

• relaunch rancher desktop
• run docker-compose up -d
• exec into pod docker-compose exec php bash
• run composer install

Observe that the command now executes successfully.
