Before you change production

This page includes public source URLs in the imported troubleshooting record. Compare those references with your version and environment before applying changes.

Reproduce the smallest failing action and save non-secret logs before changing configuration.
Check versions for Docker, related SDKs, package managers, CI runners, and hosting providers.
Change one setting or dependency at a time, then rerun the same failing command or request.
Avoid destructive commands, credential rotation, billing changes, or security relaxations without a rollback plan.

What this error means

Service marked as 'unhealthy' in docker-compose ps output after container restart or update is a Docker failure pattern reported for developers trying to diagnose why docker compose service remains in unhealthy state after restart; fix healthcheck configuration, dependency ordering, or resource constraints. Based on the imported evidence, treat this as a tool-specific troubleshooting page rather than a generic API error.

Why this happens

Widely-searched Docker pattern not yet covered on dev-error-db. Unhealthy state is a distinct diagnosis surface from 'cannot connect to daemon'. Covers cases where healthcheck misconfiguration or slow startup causes persistent unhealthy flag, breaking orchestration. Category mapping: Docker Compose → Docker per SKILL.md exact mapping.

Quick fixes

Confirm the exact error signature matches Service marked as 'unhealthy' in docker-compose ps output after container restart or update.
Check the Docker account, local tool state, and provider configuration involved in the failing workflow.
Compare the failing environment with a known working setup, then change one configuration value at a time.

Platform/tool-specific checks

Verify the command, editor, extension, or API client that produced the error.
Compare local settings with CI, deployment, or editor-level settings when the error appears in only one environment.
Avoid deleting credentials, local model data, or project settings until the failing scope is clear.

Capture the exact error message and the command, editor action, or request that triggered it.
Check whether the failure is account/auth, quota/rate, model/provider, local runtime, or deployment configuration.
Review the source evidence below and compare it with your environment.
Apply one change at a time and rerun the smallest failing action.
Keep the working fix documented for the team or deployment environment.

How to prevent it

Keep provider/tool configuration documented.
Record non-secret diagnostics such as tool version, provider name, model name, and command path.
Add a lightweight check before CI or production workflows depend on the tool.
