/install laolaoqi-docker-health
功能描述
Monitor Docker container health: running status, CPU/memory usage, restart counts, and available image updates. Use when a user requests Docker health checks...
使用说明 (SKILL.md)
Docker Health Monitor
Script
scripts/docker-health.sh — the single entry point for all checks.
The script is self-contained and works on any system with Docker installed. It auto-detects the Docker socket availability and gracefully handles permission issues.
Quick Start
Run a full health report:
bash scripts/docker-health.sh --all
Or with no arguments (same as --all):
bash scripts/docker-health.sh
Individual Checks
Run any single check by name:
| Command | What it checks |
|---|---|
--status |
Lists all containers with their current status (running, stopped, paused, etc.) |
--resources |
Shows CPU and memory usage per container via docker stats |
--restarts |
Flags containers that have restarted more than 3 times |
--images |
Checks for available image updates by comparing local image digests with registry |
--full |
Runs all checks in sequence (same as --all) |
Example:
bash scripts/docker-health.sh --status --restarts
Full Audit Workflow
- Run
bash scripts/docker-health.sh --all - The script outputs a formatted report to stdout
- Key sections: container status summary, resource usage table, restart warnings, image update availability
Common Findings & Recommendations
- High restart counts (>3): Indicates container instability — check logs with
docker logs \x3Ccontainer>and review healthcheck configuration - High memory usage: Consider setting
--memorylimits in the container's run/stack config; check for memory leaks in the application - High CPU usage: Investigate application processes; consider CPU limits or horizontal scaling
- Outdated images: Run
docker pullto update images; consider automated update workflows (watchtower, renovate-bot) - Exited containers: Check exit codes — 0 means intentional stop, non-zero indicates errors
Notes
- Requires access to the Docker socket (
/var/run/docker.sock) — run as root or add user to thedockergroup --resourcesrunsdocker statsin non-streaming mode (one-shot per container) for quick snapshots--imageschecks are advisory — usesdocker inspectfor image digests and checks for newer versions; requires network access to the registry- Works with both local Docker and remote Docker contexts (DOCKER_HOST env var)
安全使用建议
Install only if you want the agent to inspect Docker with Docker-socket-level privileges. Avoid --all or --images on production or remote Docker contexts unless you accept that the script may pull images and change the Docker image cache; use --status, --resources, or --restarts for read-only checks until the image-check behavior is clarified or fixed.
能力评估
Purpose & Capability
Status, stats, and restart reporting are aligned with Docker health monitoring, but the image freshness check mutates Docker image state by pulling images rather than only reporting.
Instruction Scope
The default --all/no-argument workflow includes the image check, so a routine health report may perform network pulls without a separate approval step.
Install Mechanism
There is no automatic installer and the shell script is readable, but registry requirements do not declare the Docker dependency or Docker access capability.
Credentials
Docker daemon access, root/docker group use, and DOCKER_HOST remote contexts are disclosed and expected for monitoring, but they are high-privilege environments.
Persistence & Privilege
docker pull can persistently update the Docker image cache/tag on the selected daemon, including remote contexts, which exceeds a purely read-only health check.
