Manyfold Most global configuration for Manyfold is via environment variables. These could be set in your docker configuration as shown in Get Started, in a .env file for local development, or in some other way that makes sense for your deployment setup.
This page lists the available environment variables, and describes the effect of each one.
Required
The variables in this section must be set, or the application will not start.
DATABASE_URL
A string that includes all the information necessary to connect to a PostgreSQL database, in the form postgresql://{username}:{password}@{database_server}/{database_name}?pool=5. For a complete description, and more options, see the PostgreSQL connection string documentation.
Alternatively, you can set server, username, password and name separately; see the Database section.
REDIS_URL
A string that includes all the information necessary to connect to a Redis server, in the form redis://{redis_server}:{port}/{dbnumber}; for instance redis://redis:6379/1.
SECRET_KEY_BASE
A secret key used to sign browser cookies; normally a 128-digit hexadecimal number, but any long random string will do. If you have the code checked out, you can generate one with rake secret. Changing this will invalidate all user cookies and sessions.
Features
DEMO_MODE
Version 0.55.0+
Set to enabled to put the entire site into the demo mode used on try.manyfold.app. In this mode, all deletion, upload, and advanced admin features are disabled, even in single-user mode and for administrator users. You’re pretty unlikely to need it, though perhaps you could use it as a sort of “emergency lockdown” mode.
REGISTRATION
Version 0.59.0+
If MULTIUSER is enabled, set to enabled to allow new users to sign up for account. If disabled, users will need to be invited by an admin. Off by default.
MULTIUSER
Version 0.59.0+
Set to enabled to turn on multiuser features such as account login, signup (with REGISTRATION option), permissions, roles, and so on. By default this is off, and Manyfold operates in single-user mode without any login necessary; however, if you’re exposing your Manyfold instance on the public Internet, even if you intend to only use it yourself, it’s probably a good idea to enable multiuser for security.
You should set a secure administrator password before turning on multiuser mode. Manyfold should prompt you to do so when you first access version 0.59.0 or above.
Network
RAILS_RELATIVE_URL_ROOT
If you are mapping Manyfold to a non-root path via a reverse proxy like nginx, use this option to tell Manyfold what the root path is; for instance /manyfold.
Database
Instead of setting DATABASE_URL as above, you can set separate variables for each component. If you do this, all variables in this section are required.
DATABASE_HOST
Version 0.60.0+
The hostname of your PostgreSQL server.
DATABASE_USER
Version 0.60.0+
The username used to authenticate to PostgreSQL.
DATABASE_PASSWORD
Version 0.60.0+
The password used to authenticate to PostgreSQL.
DATABASE_NAME
Version 0.60.0+
Your PostgreSQL database name.
Some multiuser features are only enabled if an email server is configured, such as password recovery, email verification, and so on.
In order to send mail, you need an SMTP server to send through; this could be your own local mail server, your own email host like gmail, or a hosted SMTP service like Mandrill.
SMTP_SERVER
Version 0.61.0+
The hostname of your SMTP server, e.g. smtp.example.com. The default port 25 will be used.
If the server supports TLS, it will be used automatically with STARTTLS, but otherwise an unencrypted connection will be used. See ActionMailer’s SMTP documentation for details. Defaults to localhost.
SMTP_USERNAME
Version 0.61.0+
The username for your mail server, if authentication is required.
SMTP_PASSWORD
Version 0.61.0+
The password for your mail server, if authentication is required.
SMTP_FROM_ADDRESS
Version 0.61.0+
The email address that mails should appear to be sent from. If not set, mail is sent from notifications@{PUBLIC_HOSTNAME}.
PUBLIC_HOSTNAME
Version 0.61.0+
The hostname of your publicly-accessible service, e.g. try.manyfold.app. This variable is used to create links in emails, and must be set for email delivery to work.
PUBLIC_PORT
Version 0.61.0+
If your public service is on a non-standard port, set it here (e.g. 3214).
Miscellaneous
USAGE_REPORTING_URL
Version 0.67.0+
Set this URL in order to redirect anonymous usage tracking to your own endpoint; mainly if you want to verify what we’re sending. See the tracking page for more details.
