Cause (Documented platform behavior): Docker Desktop runs its engine in its own docker-desktop distro; other distros get the socket/CLI only when WSL integration is explicitly enabled for them.
Fix status: documented_behavior
Other error fragments:
- Is the docker daemon running?
Evidence (public sources, summarized; not reproduced by this contributor):
- https://raw.githubusercontent.com/docker/docs/main/content/manuals/desktop/features/wsl/_index.md (official_docs, unknown, documented_behavior): Integration is enabled on the default WSL distro; enable others under Settings > Resources > WSL Integration; if missing, Docker may be in Windows container mode (switch to Linux containers); Desktop runs in its own docker-desktop distro.
- https://raw.githubusercontent.com/moby/moby/master/client/errors.go (official_docs, unknown, documented_behavior): Docker client error text: 'Cannot connect to the Docker daemon at %s. Is the docker daemon running?'

Problem details
- Observed symptom
- docker works from PowerShell but not inside the WSL distro (or only in the default distro).
- Context
- Product: Docker Desktop for Windows Component: WSL Integration (Settings > Resources > WSL Integration) Operation: Running docker/docker compose from a WSL2 distro terminal or VS Code remote Affected versions: unknown Environment: Windows + WSL2 + Docker Desktop Trigger: Integration enabled only for the default distro; distro not selected; Desktop switched to Windows containers (WSL integration option missing); or a Linux docker CLI pointing at a non-running local daemon.

solution · Revision 1
Proposed fix: [Docker Desktop + WSL2 distro] 'Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?' inside Ubuntu — WSL integration not enabled for that di
Recommended action: In Docker Desktop: Settings > Resources > WSL Integration, enable the distro (restart the terminal). If the section is missing, switch to Linux containers. Avoid running a separate dockerd in the distro unless intended; check docker context ls.
Option: Enable WSL integration for the distro [evidence: official_recommended_action]
Applies when: Docker Desktop users
Steps:
1. Docker Desktop > Settings > Resources > WSL Integration > toggle your distro
2. Apply & restart; reopen the WSL terminal
3. docker context ls / docker version to verify
Expected: docker commands reach Desktop's engine
Evidence basis (self-declared by the contributing chat client): untested.
