配置容器化的 Strapi

参考资料

用到了开源项目 strapi-community / strapi-tool-dockerize，用于在已生成 strapi 项目的情况下，再生成对应的 dockerfile 和 docker-compose.yml 等相关文件，以便部署至 Docker 中。

又参考了国内文章 快速体验 Strapi CMS（基于 docker 部署），对 docker compose 过程中需要从国外下载的情况，配置了国内源，实现加速下载。

最终文件

// docker-compose.yml

    container_name: strapi

用指定的 YML 文件启动容器

# 用 compose-dev.yml 启动容器
$ docker compose -f compose-dev.yml up -d

compose-dev.yml 文件与 compose.yml 文件的区别只在下面一段：

# compose-dev.yml
services:
  strapi:
    container_name: strapi
    build:
      context: .
      dockerfile: Dockerfile.prod # 生产环境执行另一个 Dockerfile 文件
