In general we try to avoid Redis flushes, but it’s not completely the end of the world if it does get flushed. Worst case, some emails might not get sent such as password resets and users will need to re-request.

I’m not using Docker. I deployed it through Capistrano. It’s production.

Yes, I know that. But for Chinese users, Docker is not a good choice: it’s intended for convenience but due to the network block(GFW) from within China, bundler install fails frequently for network error. So Chinese Docker user has to manually edit the Docker templates and configs and so on to fix that. It’s not easy, not to say that the Docker image download is VERY SLOW in China, and I’m afraid someday it may be totally unavailable. So a workaround for me is to use bundler package to avoid network download for installing Ruby Gems, which I’ve prepared in some special way before. In short, I need a way with highly custom installation script and Capistrano fits me. Rather complex, right?

I am pretty sure @fantasticfears had a workaround for this.

Thanks. However I tried Taobao mirror before, that doesn’t always work: Gems of required(new) version had been missing for 1+ months because the mirror server stopped syncing with official source for unknown reason. Here is an example: [Could not find email\_reply\_trimmer-0.1.1 in any of the sources · Issue #50 · alibaba-archive/ruby.taobao.org · GitHub](https://github.com/alibaba/ruby.taobao.org/issues/50)
Taobao mirror is not always reliable.

Thanks but @fantasticfears’s solution depends on Taobao mirror, which is not always reliable. Please see my previous reply for details.

It’s been moved to RubyChina mirror. I documented them [here](https://meta.discoursecn.org/t/%E5%9C%A8%E5%A4%A7%E9%99%86%E5%9C%B0%E5%8C%BA%E7%9A%84%E4%BA%91%E4%B8%8A%E9%83%A8%E7%BD%B2-Discourse/28) and [there](https://meta.discoursecn.org/t/webchinatemplateyml-%E4%B8%AD%E7%9A%84%E6%B7%98%E5%AE%9D%E6%BA%90%E6%9B%B4%E6%8D%A2%E4%B8%BA-Ruby-China-%E7%9A%84%E9%95%9C%E5%83%8F%E6%BA%90/972) in Chinese.
You have more than one way to fix this, either by mirrors or by proxy. If you have a reliable proxy, you don’t even bother whether a mirror is perfectly stable to you. Besides, RubyChina mirror is rather stable comparing to the launch. [Issues · ruby-china/rubygems-mirror · GitHub](https://github.com/ruby-china/rubygems-mirror/issues?q=is%3Aissue+is%3Aclosed)
Docker can also employ a proxy as described in the documentation.
If you are using `Capistrano`, you have more choices since you are a senior developer.

Thanks! I’ll look into the Docker solution again when I have to turn to it. For now, my Capistrano deployment has been working well. Thanks for all your help!
