HumanLayer云端部署指南：Docker容器化、Kubernetes编排和监控配置
项目地址: https://gitcode.com/GitHub_Trending/hu/humanlayer 概述
HumanLayer是一个革命性的人工智能代理框架，它使AI代理能够通过工具调用和异步工作流与人类进行通信。在云端部署HumanLayer时，合理的容器化策略、编排方案和监控配置至关重要。本文将深入探讨HumanLayer的云端部署最佳实践。
核心架构概览
Docker容器化策略
基础镜像选择
HumanLayer官方提供基于Python 3.11的Slim镜像，确保运行时环境的最小化和安全性：
# syntax=docker/dockerfile:1
FROM python:3.11-slim-bookworm as prod
WORKDIR /app
RUN apt update && apt upgrade -y && apt clean
ENV POETRY_VERSION=1.7 \
POETRY_VIRTUALENVS_CREATE=false
RUN pip install "poetry==$POETRY_VERSION"
COPY pyproject.toml poetry.lock /app/
RUN --mount=type=cache,target=/root/.cache/pypoetry/cache \
--mount=type=cache,target=/root/.cache/pypoetry/artifacts \
poetry install --no-interaction --no-ansi --without dev
COPY humanlayer /code/humanlayer
ENTRYPOINT ["humanlayer"]
多阶段构建优化
采用多阶段构建策略，分离开发环境和生产环境：
FROM prod as dev
RUN poetry install --no-interaction --no-ansi --no-root
ENTRYPOINT ["bin/bash", "-c"]
依赖管理最佳实践
使用Poetry进行依赖管理，确保依赖版本的精确控制：
[tool.poetry]
name = "humanlayer"
version = "0.1.0"
description = "HumanLayer enables AI agents to communicate with humans"
authors = ["HumanLayer Team"]
[tool.poetry.dependencies]
python = "^3.11"
anthropic = "^0.25.2"
openai = "^1.12.0"
langchain = "^0.1.0"
fastapi = "^0.104.1"
uvicorn = "^0.24.0"
[tool.poetry.group.dev.dependencies]
pytest = "^7.4.3"
black = "^23.11.0"
mypy = "^1.7.0"
