CARD TITLE (intent, not commit subject): installer: Docker Compose v2 not installable on Debian bookworm ARM64 - store apps will silently fail

Autonomous build of board card tsk-l7ds7d.

Use Docker official apt repository when distro apt lacks both Compose package names, verify docker compose after installation, and surface failures in the installer summary and health-check API.

Summary by CodeRabbit

  • New Features

    • Docker Compose v2 installation now supports multiple Linux package managers.
    • Debian Bookworm ARM64 systems can fall back to Docker’s official repository when Compose is unavailable through standard packages.
    • Installer summaries now show whether Docker Compose is available, skipped, or unavailable.
  • Bug Fixes

    • Docker Compose failures are now reported clearly instead of being silently overlooked.
    • Health checks now verify Docker Compose v2 and provide actionable status details.

Use Docker official apt repository when distro apt lacks both Compose package names, verify docker compose after installation, and surface failures in the installer summary and health-check API.

📝 Walkthrough

Walkthrough

The installer now installs or reports Docker Compose v2, including an official Docker repository fallback for Debian bookworm ARM64. The dashboard health check runs docker compose version and reports Compose errors.

Changes

Docker Compose availability

Layer / File(s) Summary
Installer Compose installation and reporting
scripts/install-server.sh, tests/test_install_server.sh, tests/test_install_server_docker_repo.py, changelog.d/tsk-l7ds7d-compose-bookworm-arm64.md
The installer tracks Compose status, installs Compose v2 through supported package managers, uses Docker’s official apt repository as a fallback, verifies the plugin, and reports skipped or unavailable states. Tests cover failure reporting and the Debian bookworm ARM64 fallback.
Dashboard Compose health check
tinyagentos/routes/dashboard.py, tests/test_routes_dashboard.py
The health-check endpoint runs an asynchronous Compose v2 check and returns version, unavailable, or error details. Tests verify error responses and checker invocation.

Priority: ➖ Normal

Estimated code review effort: 3 (Moderate) | ~25 minutes

Change: Bug fix

Merge Risk: 🟡 Moderate · up to 9dd3a

Timed-out health checks can leave Compose subprocesses running, degrading the dashboard service over repeated requests. macOS installations with working Docker Compose are also reported as unavailable. Resolve these before merge.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Detect Compose before reporting it as unavailable on macOS.

If Docker Desktop or Colima is already installed, docker compose version can succeed. This path still records unavailable, so the final installer summary falsely reports that Store Docker apps will fail.

Terminate the Compose process after a timeout.

When proc.communicate() exceeds five seconds, asyncio.wait_for cancels communication but leaves the docker compose subprocess running. _check_docker_compose catches the timeout through except Exception and returns without cleanup. Terminate or kill proc, then await its cleanup before returning the error result.

WARNING: Test at line 159 searches for _apt_compose_rc != 0 which no longer exists in _install_compose_v2

The change from _apt_install_compose to _install_compose_v2 at this line replaced the old elif (( _apt_compose_rc != 0 )) branch with an else branch. The downstream grep on line 159 will always fail because the literal string _apt_compose_rc != 0 is no longer present in the script.

WARNING: Missing warning when Docker official repo fallback fails after missing-package rc==2

When _apt_install_compose returns 2 (package not in distro) and _apt_install_docker_official_repo also fails, the code falls through silently to the final "unavailable" block without warning that the official repo fallback was attempted and failed.

SUGGESTION: Test not hermetic w.r.t. incus

_run_preexisting_docker_compose_path extracts ensure_docker_for_apps but does not stub command -v incus or _configure_docker_incus_coexistence. If incus is installed on the test host, ensure_docker_for_apps calls the undefined _configure_docker_incus_coexistence, causing the test to abort.
