[rubygems.org](http://rubygems.org) hosts its resource in Amazon S3 which is disturbed by GFW. So `gem` and `bundle` complain from time to time.

This guide assumes you used docker installation. This guide also has a version in Chinese. [中文指南](https://meta.discoursecn.org/t/discourse/28)

### Add a template

Open your congiruation file, say, `app.yml`.

Add a reference to the china template:

```
templates:
  - "templates/postgres.template.yml"
  - "templates/redis.template.yml"
  - "templates/sshd.template.yml"
  - "templates/web.template.yml"
  - "templates/web.china.yml"

```

### Bootstrap docker container

Rebuild your app

```
./launcher rebuild app

```

Or bootstrap:

```
./launcher bootstrap app

```

You are done! Everything should work then.
