Environment Variables ROOT_URL:  the URL under which titra is served. Could be http://localhost:3000 for a local instance or https://app.titra.io for a setup with reverse proxy and DNS records. MONGO_URL : the URL of the mongoDB backend (e.g. mongodb://localhost:27017/titra) MONGO_OPLOG_URL : the URL pointing to the OPLOG of the mongoDB backend (e.g. mongodb://localhost:27017/local) MAIL_URL:  The server reads from the  MAIL_URL  environment variable to determine how to send mail. The  MAIL_URL  should reference an  SMTP  server and use the form: smtp://USERNAME:PASSWORD@HOST:PORT or smtps://USERNAME:PASSWORD@HOST:PORT The smtp s :// form (the  s  is for “ secure ”) should be used if the  mail server requires TLS/SSL  (and does not use STARTTLS) and is most common on port 465. Connections which start unencrypted prior to being upgraded to TLS/SSL (using STARTTLS) typically use port 587 (and sometimes 25) and should use  smtp:// . For more information see the  Nodemailer  docs METEOR_SETTINGS are Deprecated starting with titra version 0.18.0 Please use the new Globalsettings available for administrators through the Administration page. METEOR_SETTINGS : the titra specific settings in JSON format, all settings have to belong to the “public” hierarchy. The available parameters are: disablePublic: true/false – if set to true, projects can not be set as public enableAnonymousLogins: true/false – if set to true, the /try path will be available allowing anonymous accounts to be created on the fly. Below is an example for a METEOR_SETTINGS environment variable value: { "public": { "disablePublic": "true", "enableAnonymousLogins": "true" } }
