OpenCloud

Description

OpenCloud is a sovereign self-hosted file sync, share, and collaboration platform maintained by the Heinlein Group. It is a fork of the OpenCloud Infinite Scale codebase and is published as the opencloudeu/opencloud container image.

Overview

This role deploys OpenCloud using Docker Compose in single-binary mode and exposes it under open.cloud.{{ DOMAIN_PRIMARY }} through the central reverse proxy. It wires the deployment to the shared Keycloak realm via OIDC, sources users and groups from the central svc-db-openldap directory, and runs side by side with web-app-nextcloud so both file platforms can coexist on the same host. For identity wiring details see IAM.md and LDAP.md.

Cosmos

The diagram places OpenCloud 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). 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

Sovereign File Sync and Share: Self-host file sync, shares, and collaborative spaces under your own domain.
Single Sign-On: Users authenticate once via Keycloak and reuse the session across the platform.
Central User Directory: Users and groups are read from a shared OpenLDAP backend, so accounts stay consistent across apps.
Auto-Provisioning: New OIDC users are created on first login with username equal to the LDAP uid, and group claims drive role assignment.
OpenTalk Cross-Launch: Start a video meeting in OpenTalk from a file context without re-authenticating when web-app-opentalk is deployed alongside.
Coexists with Nextcloud: Runs in parallel with web-app-nextcloud on a distinct canonical hostname.

Quick Setup

Development

Clone, set up the workstation, and deploy OpenCloud 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-opencloud full_cycle=false

Production

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

APP=web-app-opencloud
HOST=<your-server>
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="$HOST" -e TLS_MODE="$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\", \"users\": {\"administrator\": {\"authorized_keys\": [\"$SSH_PUBLIC_KEY\"]}}}" &&
    infinito administration deploy dedicated "$INVENTORY/devices.yml" \
      --password-file "$INVENTORY/.password" \
      --diff -vv'

Developer Notes

See IAM.md for OIDC discovery and verification commands, and LDAP.md for the directory binding and schema mapping. Open follow-up items are tracked in TODO.md.
