This guide assumes you used docker installation. This guide also has a version in Chinese. 中文指南

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.
