Wan2.2-I2V-A14B持续集成/持续部署CI/CD流水线搭建1. 引言在AI模型服务开发中频繁的迭代更新是常态。每次代码修改后手动执行测试、构建和部署不仅效率低下还容易出错。本文将带你从零开始为Wan2.2-I2V-A14B模型服务搭建一套完整的CI/CD流水线实现代码提交后的全自动流程。通过本教程你将学会如何配置基础环境包括MySQL数据库使用GitLab CI或Jenkins搭建自动化流水线实现从代码提交到测试环境部署的全流程自动化确保模型服务更新的高效性和可靠性2. 环境准备2.1 基础软件安装在开始之前请确保你的服务器已安装以下软件Docker 20.10Docker Compose 1.29GitLab Runner或JenkinsMySQL 8.0用于存储模型元数据2.2 MySQL安装与配置MySQL作为模型服务的元数据存储是CI/CD流程中的重要组件。以下是安装步骤# 安装MySQL服务器 sudo apt update sudo apt install mysql-server # 启动MySQL服务 sudo systemctl start mysql sudo systemctl enable mysql # 安全配置 sudo mysql_secure_installation # 创建专用数据库和用户 mysql -u root -p CREATE DATABASE wan2_model; CREATE USER wan2user% IDENTIFIED BY your_secure_password; GRANT ALL PRIVILEGES ON wan2_model.* TO wan2user%; FLUSH PRIVILEGES;2.3 Docker环境配置确保Docker已正确安装并配置# 检查Docker版本 docker --version docker-compose --version # 创建Docker网络用于容器间通信 docker network create wan2-network3. CI/CD流水线设计3.1 整体流程概述我们的CI/CD流水线将包含以下阶段代码提交触发流水线代码质量检查Lint单元测试执行Docker镜像构建镜像推送到私有仓库测试环境部署集成测试执行人工审核可选生产环境部署可选3.2 GitLab CI配置如果你使用GitLab以下是.gitlab-ci.yml配置示例stages: - lint - test - build - deploy_test - integration_test variables: DOCKER_IMAGE: registry.yourcompany.com/wan2-i2v-a14b:$CI_COMMIT_SHORT_SHA MYSQL_HOST: mysql-test MYSQL_DATABASE: wan2_model MYSQL_USER: wan2user MYSQL_PASSWORD: $MYSQL_PASSWORD lint: stage: lint image: python:3.9 script: - pip install flake8 black - flake8 --max-line-length120 . - black --check . unit_test: stage: test image: python:3.9 services: - name: mysql:8.0 alias: mysql-test script: - pip install -r requirements.txt - pytest tests/unit --covsrc --cov-reportxml artifacts: reports: cobertura: coverage.xml build_image: stage: build image: docker:20.10 services: - docker:dind script: - docker build -t $DOCKER_IMAGE . - docker login -u $CI_REGISTRY_USER -p $CI_REGISTRY_PASSWORD $CI_REGISTRY - docker push $DOCKER_IMAGE deploy_test: stage: deploy_test image: docker:20.10 services: - docker:dind script: - docker-compose -f docker-compose.test.yml up -d environment: name: test url: http://wan2-test.yourcompany.com integration_test: stage: integration_test image: python:3.9 script: - pip install -r requirements.txt - pytest tests/integration needs: [deploy_test]3.3 Jenkins配置如果你使用Jenkins可以按照以下步骤配置安装必要插件Docker PipelineGitPipelineBlue Ocean创建Jenkinsfilepipeline { agent any environment { DOCKER_IMAGE registry.yourcompany.com/wan2-i2v-a14b:${env.BUILD_ID} MYSQL_HOST mysql-test MYSQL_DATABASE wan2_model MYSQL_USER wan2user MYSQL_PASSWORD credentials(mysql-password) } stages { stage(Lint) { agent { docker { image python:3.9 } } steps { sh pip install flake8 black sh flake8 --max-line-length120 . sh black --check . } } stage(Unit Test) { agent { docker { image python:3.9 args --network wan2-network } } steps { sh pip install -r requirements.txt sh pytest tests/unit --covsrc --cov-reportxml junit test-reports/*.xml } } stage(Build Image) { agent { docker { image docker:20.10 args -v /var/run/docker.sock:/var/run/docker.sock } } steps { script { docker.withRegistry(https://registry.yourcompany.com, docker-credentials) { docker.build($DOCKER_IMAGE).push() } } } } stage(Deploy to Test) { agent any steps { sh docker-compose -f docker-compose.test.yml up -d } } stage(Integration Test) { agent { docker { image python:3.9 } } steps { sh pip install -r requirements.txt sh pytest tests/integration } } } post { always { sh docker-compose -f docker-compose.test.yml down } } }4. 关键组件配置4.1 Dockerfile配置以下是Wan2.2-I2V-A14B模型的Dockerfile示例FROM python:3.9-slim WORKDIR /app # 安装系统依赖 RUN apt-get update apt-get install -y \ libgl1-mesa-glx \ rm -rf /var/lib/apt/lists/* # 复制依赖文件并安装 COPY requirements.txt .
