Customize Zulip
Once you’ve got Zulip set up, you’ll likely want to configure it the way you like.
Making changes
Most configuration can be done by a realm administrator, on the web. For those settings, see the documentation for realm administrators.
This page discusses additional configuration that a system
administrator can do. To change any of the following settings, edit
the /etc/zulip/settings.py file on your Zulip server, and then
restart the server with the following command:
su zulip -c '/home/zulip/deployments/current/scripts/restart-server'
Zulip has dozens of settings documented in the comments in
/etc/zulip/settings.py; you can review the latest version of the
settings.py template, and if you’ve upgraded
from an old versions of Zulip, we recommend carefully updating your
/etc/zulip/settings.py to fold in the inline
comment documentation for new configuration settings after upgrading
to each new major release.
Since Zulip’s settings file is a Python script, there are a number of other things that one can configure that are not documented; ask on chat.zulip.org if there’s something you’d like to do but can’t figure out how to.
Specific settings
Domain and email settings
EXTERNAL_HOST: the user-accessible domain name for your Zulip
installation (i.e., what users will type in their web browser). This
should of course match the DNS name you configured to point to your
server and for which you configured SSL certificates. If you passed
--hostname to the installer, this will be prefilled with that value.
ZULIP_ADMINISTRATOR: the email address of the person or team
maintaining this installation and who will get support and error
emails. If you passed --email to the installer, this will be
prefilled with that value.
Authentication backends
AUTHENTICATION_BACKENDS: Zulip supports a wide range of popular
options for authenticating users to your server, including Google
auth, GitHub auth, LDAP, SAML, REMOTE_USER, and more.
If you want an additional or different authentication backend, you
will need to uncomment one or more and then do any additional
configuration required for that backend as documented in the
settings.py file. See the
section on authentication for more
detail on the available authentication backends and how to configure
them.
Mobile and desktop apps
The Zulip apps expect to be talking to servers with a properly signed SSL certificate, in most cases and will not accept a self-signed certificate. You should get a proper SSL certificate before testing the apps.
Because of how Google and Apple have architected the security model of
their push notification protocols, the Zulip mobile apps for
iOS and
Android
can only receive push notifications from a single Zulip server. We
have configured that server to be push.zulipchat.com, and offer a
push notification forwarding service that
forwards push notifications through our servers to mobile devices.
Read the linked documentation for instructions on how to register for
and configure this service.
Terms of Service and Privacy policy
Zulip allows you to configure your server’s Terms of Service and
Privacy Policy pages (/terms and /privacy, respectively). You can
use the TERMS_OF_SERVICE and PRIVACY_POLICY settings to configure
the path to your server’s policies. The syntax is Markdown (with
support for included HTML). A good approach is to use paths like
/etc/zulip/terms.md, so that it’s easy to back up your policy
configuration along with your other Zulip server configuration.
Miscellaneous server settings
Some popular settings in /etc/zulip/settings.py include:
The Twitter integration, which provides pretty inline previews of tweets.
The email gateway, which lets users send emails into Zulip.
Zulip announcement list
If you haven’t already, subscribe to the zulip-announce list so that you can receive important announces like new Zulip releases or major changes to the app ecosystem.
Enjoy your Zulip installation!
If you discover things that you wish had been documented, please contribute documentation suggestions either via a GitHub issue or pull request; we love even small contributions, and we’d love to make the Zulip documentation cover everything anyone might want to know about running Zulip in production.
