Fider¶

Description¶

Fider is an open-source community feedback and voting platform that allows teams to collect, prioritize, and track feature requests and ideas.

Overview¶

This role deploys Fider as part of the Infinito.Nexus stack using a single Docker Compose container backed by PostgreSQL. It configures SSO via Keycloak automatically on first deploy, optional email notifications via Mailu, and HTTPS via NGINX reverse proxy.

The setup tasks handle the full first-deploy bootstrap automatically. Steps 1 to 3 run on every deploy, with or without SSO; step 4 runs only when services.sso.enabled is true:

Tenant bootstrap: calls Fider’s POST /_api/tenants API to create the initial tenant.
Admin user creation: inserts the admin user directly into the users table, bypassing email verification. Idempotent via WHERE NOT EXISTS.
Tenant activation: sets status=1 on the tenant row so Fider serves the public page.
OIDC provider: inserts the Keycloak provider into oauth_providers. Idempotent via ON CONFLICT (tenant_id, provider) DO UPDATE.

When a user logs in via Keycloak for the first time, Fider matches their email to the existing admin user and links the OIDC provider automatically. To enable SSO, set services.sso.enabled: true (the default) and ensure OIDC.CLIENT.SECRET is configured.

Cosmos¶

The diagram places Fider in the Infinito.Nexus cosmos: the components it deploys (capabilities), the central services it consumes (dependencies), and its outward reach (federation and bridged external networks).

Solid 1:1 edges are fixed relationships; dashed 0..1 edges are conditional (enabled only in matching deployments); red 0..0 edges are turned off in this role. Node markers show the role’s deploy modes (💻 host, 🐳 compose, 🐝 swarm); ❌ marks a service that is explicitly turned off, and ⚙️ an Ansible role dependency declared in meta/main.yml.

Features¶

Single-container deployment via Docker Compose.
PostgreSQL database: all data including attachments stored in the database, no extra volumes needed.
SSO via Keycloak: configured automatically on first deploy.
Email notifications via Mailu (optional).
HTTPS enforced via NGINX reverse proxy.

Quick Setup¶

Development¶

Clone, set up the workstation, and deploy Fider onto the local stack:

git clone https://github.com/infinito-nexus/core.git
cd core
make onboard
make compose-deploy mode=reinstall apps=web-app-fider full_cycle=false

Production¶

Run the published image to provision the inventory and deploy Fider to a managed server (the mounted volume persists the inventory):

APP=web-app-fider
HOST=<your-server>
DOMAIN=<your-domain>
TLS_MODE=self_signed
SSH_PUBLIC_KEY="<your-ssh-public-key>"

docker run --rm -it \
  -v "$PWD/inventories:/etc/infinito.nexus/inventories" \
  -e APP="$APP" -e HOST="$HOST" -e DOMAIN="$DOMAIN" -e TLS_MODE="$TLS_MODE" -e SSH_PUBLIC_KEY="$SSH_PUBLIC_KEY" \
  ghcr.io/infinito-nexus/core/debian bash -c '
    INVENTORY=/etc/infinito.nexus/inventories/production
    infinito administration inventory provision "$INVENTORY" \
      --inventory-file "$INVENTORY/devices.yml" \
      --host "$HOST" \
      --include "$APP" \
      --vars "{\"TLS_MODE\": \"$TLS_MODE\", \"DOMAIN_PRIMARY\": \"$DOMAIN\", \"users\": {\"administrator\": {\"authorized_keys\": [\"$SSH_PUBLIC_KEY\"]}}}" &&
    infinito administration deploy dedicated "$INVENTORY/devices.yml" \
      --password-file "$INVENTORY/.password" \
      --diff -vv'

Configuration¶

Key settings in meta/services.yml and meta/server.yml:

Key	Default	Description
`services.sso.enabled`	`true`	Automate Keycloak OIDC setup
`services.postgres.enabled`	`true`	Enable PostgreSQL for Fider
`services.postgres.shared`	`true`	Reuse the shared PostgreSQL provider
`services.fider.version`	`stable`	Docker image tag
`domains.canonical`	`fider.{{ DOMAIN_PRIMARY }}`	Public domain
`server.status_codes.default`	`[200, 301, 302, 405]`	Expected HTTP codes for health check (405 because Fider returns 405 on HEAD requests to `/`)

Persona contract opt-outs¶

The shared biber and administrator persona journeys are opted out via PERSONA_BIBER_BLOCKED / PERSONA_ADMINISTRATOR_BLOCKED in templates/playwright.env.j2. Fider’s SSO entry is a two-step modal: the header “Sign in” button only opens the provider dialog, and a second click on “Continue with … SSO” performs the Keycloak redirect, whereas the shared helper clicks exactly once and never reaches the IdP. Both journeys are covered end-to-end by this role’s own fider: admin sso login and fider: biber sso login as regular user scenarios in files/playwright/playwright.spec.js; the opt-out lapses once the shared helper learns Fider’s modal.
