SAC:Discourse

OSGeo hosts a Discourse server accessible at https://discourse.osgeo.org

The server is an LXD VM running on hosted on osgeo9 machine and administered by the OSGeo System Administration Committee.

Gory details are in private https://gitea.osgeo.org/sac/discourse/wiki/discourse

Sign up

It current allows OSGeo LDAP, OSGeo Gitea, GitHub, and local sign up methods

Administration

All administrative tasks are done via the web interface.

Some seem to require intervention on host files ( ie: receiver.yml ?).

We should put more configuration into ansible, see https://trac.osgeo.org/osgeo/ticket/3424

Mail gateway

Discourse sends mail using lists.osgeo.org as the SMTP server (see DISCOURSE_SMTP_ADDRESS in /var/discourse/containers/app.yml) and `discourse.osgeo.org` as the domain name.

Receives mail on its own, via an MX record for discourse.osgeo.org (but see https://trac.osgeo.org/osgeo/ticket/3068 for an issue about that)

Issues

Mailing list migration

Some of mailman mailing lists have been migrated to Discourse.

Details on how to ask for migration of your list are here https://discourse.osgeo.org/docs?topic=6765

Theming

We tweak the login form CSS a little in order to fix the LDAP button background, the labels, and to tweak the display order of the options.

This is done from https://discourse.osgeo.org/admin/customize/themes/1/common/scss/edit

.btn.ldap {
    background-color: #fff;
    order: 1;
}

.btn.ldap:hover {
    background-color: var( --primary-medium );
}

.btn.ldap span.btn-social-title {
    visibility: hidden;
}

.btn.ldap span.btn-social-title:before {
    visibility: visible;
    content: 'Log in with OSGeo UserID (LDAP)';
}

.btn.oidc {
    order: 2;
}

.btn.oidc span.btn-social-title {
    visibility: hidden;
}

.btn.oidc span.btn-social-title:before {
    visibility: visible;
    content: 'Log in with OSGeo Gitea';
}

.btn.passkey-login-button {
    order: 3;
