什么是 Docker？

Docker 技能为 Openclaw Skills 提供了处理容器化任务的强大接口。它弥合了 AI 编程智能体与 Docker 生态系统之间的鸿沟，确保安装、容器构建和编排工作流遵循最新的官方标准。通过集成此技能，开发者可以自动化在 macOS 和 Windows 上设置 Docker Desktop 或在 Linux 发行版上设置 Docker Engine 的过程。

此外，此 Openclaw Skills 扩展通过参考 Dockerfile 和 CLI 命令的规范文档，优先保证技术准确性。它赋予 AI 智能体调试容器连接问题、管理镜像以及执行 docker compose 配置的能力，而无需依赖过时的训练数据，使其成为现代云原生开发的重要工具。

Docker 应用场景

• 在本地开发环境中设置 Docker Desktop 或 Docker Engine。
• 从应用程序源代码构建并标记 Docker 镜像。
• 使用 docker compose 编排多容器应用程序。
• 调试容器日志并管理运行服务的生命周期。
• 从 Docker Hub 拉取并管理官方镜像。

1. 智能体根据用户意图识别出容器化或 Docker 环境设置的需求。
2. 它使用 Openclaw Skills 中定义的必需二进制文件检查 Docker CLI 是否存在。
3. 如果缺失，它会执行特定平台的安装步骤，例如 macOS 的 Homebrew 或 Linux 的 APT。
4. 该技能从官方 Docker 文档 URL 获取最新的语法和最佳实践，以避免版本不匹配。
5. 它执行 docker build 或 docker run 等命令来实现请求的容器化工作流。

Docker 配置指南

要在您的环境中启用 Docker 功能，请确保 Docker 守护进程正在运行。对于使用 Openclaw Skills 的 macOS 用户，您可以通过 Homebrew 启动安装：

brew install --cask docker

对于 Linux (Ubuntu) 用户，请删除冲突的软件包并使用官方存储库安装引擎：

sudo apt update
sudo apt install -y docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin
sudo systemctl start docker

安装完成后，通过运行以下命令验证设置：

docker run hello-world

Docker 数据架构与分类体系

Docker 技能与多种文件类型和元数据结构交互，以确保 Openclaw Skills 内部的环境一致性：

Docker — Install and Use Containers

Enables OpenClaw (and Cursor) to install Docker and use it reliably. Base all guidance on official Docker docs; when in doubt, fetch from canonical URLs below.

When to Apply

• User wants to install Docker (macOS, Linux, Windows)
• User asks about containers, images, Dockerfile, docker compose
• Building, running, or debugging Docker commands or workflows
• User asks for "latest Docker docs" or "how do I use Docker"

Canonical Documentation URLs

Rule: For install steps, CLI syntax, or Dockerfile instructions, fetch the relevant doc URL and use that content. Do not rely on training data for version-specific install or command details.

Installation (Reliable Paths)

macOS

Recommended: Docker Desktop

1. Download from official docs: Install Docker Desktop on Mac.
   • Apple Silicon: https://desktop.docker.com/mac/main/arm64/Docker.dmg
   • Intel: https://desktop.docker.com/mac/main/amd64/Docker.dmg
2. Open Docker.dmg, drag Docker to Applications, then open Docker.app and accept terms.
3. CLI install (optional): After downloading the DMG:

   sudo hdiutil attach Docker.dmg
   sudo /Volumes/Docker/Docker.app/Contents/MacOS/install
   sudo hdiutil detach /Volumes/Docker
   

4. Verify: docker run hello-world

OpenClaw / automation: If docker is missing and the user is on macOS, suggest installing via Homebrew: brew install --cask docker, then starting Docker Desktop so the daemon is running.

Linux (Ubuntu example)

1. Prefer Docker Engine from apt (see Install Docker Engine on Ubuntu).
2. Remove conflicting packages first:

   sudo apt remove $(dpkg --get-selections docker.io docker-compose docker-compose-v2 docker-doc podman-docker containerd runc 2>/dev/null | cut -f1)
   

3. Add Docker’s apt repo, then:

   sudo apt update
   sudo apt install -y docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin
   sudo systemctl start docker
   sudo docker run hello-world
   

4. Optional (run without sudo): Linux postinstall — add user to docker group.

Convenience script (dev/test only): curl -fsSL https://get.docker.com -o get-docker.sh && sudo sh get-docker.sh. Not recommended for production.

Windows

Use Get Docker and follow Docker Desktop for Windows (WSL2 backend recommended).

Core Workflow: Build and Run

1. Dockerfile in app directory (see reference.md or Dockerfile reference).
2. Build image: docker build -t .
3. Run container: docker run -d -p HOST_PORT:CONTAINER_PORT (e.g. -p 127.0.0.1:3000:3000).
4. List containers: docker ps (running), docker ps -a (all).
5. Stop/remove: docker stop , docker rm .

Example from official getting-started:

docker build -t getting-started .
docker run -d -p 127.0.0.1:3000:3000 getting-started
# Open http://localhost:3000

Daemon Must Be Running

• Docker Desktop (Mac/Windows): Ensure Docker Desktop app is running; docker CLI talks to its daemon.
• Linux: sudo systemctl start docker (and enable if needed).
• If the user sees "Cannot connect to the Docker daemon", direct them to start Docker Desktop or the engine service and try again.

Quick Reference

• Images: docker pull , docker images, docker rmi
• Containers: docker run, docker ps, docker stop, docker rm, docker logs
• Compose: docker compose up -d, docker compose down — use compose.yaml in project root (see Compose file reference).
• Cleanup: docker system prune -a (removes unused images/containers/networks; use with care).

• For detailed CLI and Dockerfile syntax, see reference.md.
• For full specs, fetch from the official reference and guides.
