Symptom & Impact

Compose deployments fail because the user context cannot access the Docker named pipe.

Environment & Reproduction

Triggered when CI agents or service accounts run Compose without proper group membership.

docker compose up -d

Root Cause Analysis

Security principal lacks rights to ./pipe/docker_engine or service isolation context is misconfigured.

Quick Triage

Verify account token groups and Docker service state.

whoami /groups
Get-Service docker

Step-by-Step Diagnosis

Inspect local group membership and endpoint ACL behavior.

Solution — Alternative Approaches

Run Compose under managed task with elevated local security context.

schtasks /create /tn ComposeJob /tr "docker compose up -d" /sc onstart /ru SYSTEM

Verification & Acceptance Criteria

Compose completes and all services are healthy.

docker compose ps

Rollback Plan

Remove group membership and revert service account if required.

Remove-LocalGroupMember -Group docker-users -Member DOMAINsvc_ci

Prevention & Hardening

Standardize container runner identities and least-privilege group assignments.

Get-LocalGroupMember -Group docker-users
