SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Docker-management helps you run, debug, and clean up containers and images safely instead of guessing commands during outages, disk-pressure, or broken Compose deployments.

Core Features & Use Cases

  • Container lifecycle & inspection: Start/stop/restart, view logs, exec into running services, inspect detailed state, and diagnose crashes by checking logs and runtime status.
  • Image management: Build, tag, pull/push, and prune unused or dangling images to keep storage under control.
  • Compose stacks + networking/volumes: Bring multi-service stacks up/down, validate Compose config, and manage volumes and networks for persistent data and connectivity.

Use case: Your web service fails to start after a new image deploy; use this skill to identify the failing container, inspect logs and status, rebuild images if needed, and restart the Compose stack while also cleaning up unused resources.

Quick Start

Use the docker-management skill to troubleshoot your failing Compose service by running the relevant Docker Compose up, checking the service logs, and applying targeted cleanup for unused images, containers, volumes, and networks.

Frequently Asked Questions about docker-management

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I debug a Docker container that keeps crashing after a new image deploy?▼

Docker troubleshooting involves checking container logs, inspecting runtime status, and verifying connectivity. Use this skill to identify failing containers, review error logs, and apply targeted cleanup for unused resources before restarting Compose stacks safely.

What is the best way to clean up unused Docker images and volumes when disk space is full?▼

Docker cleanup removes dangling images, stopped containers, and unattached volumes to free disk space. This skill applies targeted pruning commands for unused resources, ensuring reliable deployment operations without disk-pressure interruptions.

How do I manage a multi-service Compose stack and validate its configuration?▼

Compose stack management involves validating configurations, orchestrating multi-service deployments, and verifying container status. This skill executes deterministic lifecycle actions using Docker Compose v2, ensuring persistent data and network connectivity across services.

Do I need Docker Compose v2 to manage containers and images with this approach?▼

Docker management requires Docker Engine and Docker Compose v2 for reliable container lifecycle operations. This skill uses standard Docker CLI commands to perform deterministic actions, ensuring compatibility with image builds, volume management, and stack deployments.

Why does my Docker Compose deployment fail to start with network or volume issues?▼

Compose deployment failures from network or volume issues require inspecting container logs and validating Compose config. This skill diagnoses crashes by checking runtime status and managing volumes and networks to ensure persistent data and stable connectivity.
