Codimd是hackmd的開源版，雖然主要功能仍含hackmd差不多

但並沒有提供像是hackmd的團隊管理系統

他可以使用heroku, docker compose, k8s來架

Herkou

這是裡面最簡單的架設方式，點一下heroku的按鈕就好

https://heroku.com/deploy?template=https://github.com/hackmdio/codimd/tree/master

Config

會有一些環境變數可以設定，當然也可以deploy完後再去修改

https://hackmd.io/c/codimd-documentation/%2Fs%2Fcodimd-configuration

::heroku的DB是直接使用plugin，不用去設定CMD_DB_URL::

如果在create app時有遇到錯誤

Item could not be created:

We couldn't deploy your app because the source code violates the Salesforce Acceptable Use and External-Facing Services Policy.

::先去fork codimd的專案，然後把button和app.json裡面的連結改掉::

https://heroku.com/deploy?template=https://github.com/username/codimd/tree/master

{
"repository": "https://github.com/username/codimd",
}

如果成功create app但是有error

2022-03-23T13:45:56.526766+00:00 app[web.1]: npm ERR!

一樣得fork repo，然後去package.json改node版本

{
"engines": {
    "node": "12.22.1"
  },
}

記得deploy裡面的github要和fork的repo link起來
