用Docker方式部署rss feed生成器RSSHub

前言

rsshub是一个rss feed生成器，这点首先要理解，它不是rss feed订阅器或者rss阅读器，它是一个用来生成rss feed的工具。现在很多网站、社区、博客之类都已经不支持rss订阅，或者很多想订阅的自定义的内容（比如某个twitter用户），这时候就可以使用rsshub来生成rss feed，然后用rss订阅器来订阅这个feed就可以了。

在部署之前的一点个人经验和建议：最好弄个海外的vps或者能实现全局代理的机器来部署rsshub，因为要用rsshub来生成rss feed，首先rsshub能访问到那个网站吧，要不然一直报dial tcp io timeout就很尴尬。

部署

rsshub原生部署需要用到nodejs，我讨厌nodejs，所以选择用docker-compose方式部署。

用docker-compose方式部署，只需要搞定docker-compose.yml这个配置文件就行了。rsshub的【官方文档】也给出了配置模板，直接下载模板即可。

这是rsshub官方提供的docker-compose.yml文件（2024/09/08）。

根据文档可以确定rsshub需要用到3个镜像：rsshub本体 + redis + 浏览器，其中chrome镜像大概需要占用4GB的存储空间，请提前规划。其实整个模板里基本已经没有需要修改的地方了，直接docker-compose up -d就可以把服务拉起来使用。唯二需要修改的地方，一个可能是rsshub的port根据自己需求调整，另一个是redis-data这个数据保存路径，也是根据自己需求调整。
