一、痛点与解决方案概述

你是否在部署RedditVideoMakerBot时遭遇环境依赖冲突、多节点扩展困难或资源利用率低下等问题？本文将通过Docker容器化与Kubernetes编排方案，提供一套可复用的企业级部署架构，实现应用的高可用运行与弹性伸缩。读完本文你将获得：

• 完整的Docker镜像构建流程
• 多环境Kubernetes配置清单
• 资源优化与性能调优指南
• 监控告警与日志收集方案

二、Docker镜像构建最佳实践

2.1 基础镜像选择

RedditVideoMakerBot基于Python开发，推荐使用官方Python镜像作为基础，结合Alpine版本减小镜像体积：

FROM python:3.10-slim

WORKDIR /app

# 安装系统依赖
RUN apt-get update && apt-get install -y --no-install-recommends \
    ffmpeg \
    libmagic1 \
    && rm -rf /var/lib/apt/lists/*

# 复制依赖文件并安装
COPY requirements.txt .
RUN pip install --no-cache-dir -r requirements.txt

# 复制应用代码
COPY . .

# 设置环境变量
ENV PYTHONUNBUFFERED=1
ENV PATH="/app:${PATH}"

# 健康检查
HEALTHCHECK --interval=30s --timeout=10s --start-period=60s --retries=3 \
  CMD python -c "import os; exit(0 if os.path.exists('/app/main.py') else 1)"

# 启动命令
CMD ["python", "main.py"]

2.2 多阶段构建优化

为进一步减小镜像体积，采用多阶段构建剔除构建依赖：

# 构建阶段
FROM python:3.10 AS builder
WORKDIR /app
COPY requirements.txt .
RUN pip wheel --no-cache-dir --no-deps --wheel-dir /app/wheels -r requirements.txt

# 运行阶段
FROM python:3.10-slim
WORKDIR /app
COPY --from=builder /app/wheels /wheels
COPY --from=builder /app/requirements.txt .
RUN pip install --no-cache /wheels/*

COPY . .
CMD ["python", "main.py"]

      stabilizationWindowSeconds: 300
      policies:
      - type: Percent
        value: 10
        periodSeconds: 300

六、监控与运维体系

6.1 Prometheus监控配置

    snippets:
      pipelineStages:
        - docker: {}
        - match:
            selector: '{app="reddit-bot"}'
            stages:
              - json:
                  expressions:
                    level: level

    rules:
    - alert: HighErrorRate
      expr: sum(rate(http_requests_total{status=~"5.."}[5m])) / sum(rate(http_requests_total[5m])) > 0.05
      for: 5m
      labels:

        summary: "Pod {{ $labels.pod }} is not ready"
        description: "Pod {{ $labels.pod }} in namespace {{ $labels.namespace }} has been not ready for 10 minutes"

七、常见问题解决方案

7.1 镜像拉取失败

问题表现：Pod状态显示ImagePullBackOff 解决方案：

1. 检查镜像仓库认证：

kubectl create secret docker-registry gitcode-regcred \
  --docker-server=gitcode.com \
  --docker-username=your-username \
  --docker-password=your-token \
  --namespace=reddit-bot

2. 在Deployment中引用密钥：

imagePullSecrets:
- name: gitcode-regcred

7.2 资源不足

问题表现：Pod被驱逐或频繁重启 解决方案：

1. 调整资源请求与限制
2. 启用资源自动扩缩容
3. 优化应用内存使用

7.3 存储权限问题

问题表现：应用无法读写数据目录 解决方案：

1. 检查PVC挂载路径
2. 调整容器安全上下文：

securityContext:
  runAsUser: 1000
  runAsGroup: 3000
  fsGroup: 2000
