Migrate the search index in place instead of a full Tika re-crawl when the shared search.SchemaRevision is bumped. bleve (single instance): rebuild from the existing documents into a temp index and atomically swap, with crash recovery; auto-migrate on startup (opt-out via SEARCH_ENGINE_BLEVE_AUTO_MIGRATE). OpenSearch (scaled): versioned indices <base>-v<rev> (no alias), filled from the newest older index via a create-only scroll reindex - idempotent, never overwrites, safe to run live. 'opencloud search index migrate' fills the current-revision index; 'opencloud search index prune' drops older ones. Per-document fixups are gated on the source schema version. Trash preserved, geopoint siblings synthesized, all fields round-tripped.
Server Backend
Tip
For general information about OpenCloud and how to install please visit OpenCloud on Github and OpenCloud GmbH.
This is the main repository of the OpenCloud server. It contains the golang codebase for the backend services.
Getting Involved
The OpenCloud server is released under Apache 2.0. The project is thrilled to receive contributions in all forms. Start hacking now, there are many ways to get involved such as:
- Reporting issues or bugs
- Requesting features
- Writing documentation
- Writing code or extend our tests
- Reviewing code
- Helping others in the community
Every contribution is meaningful and appreciated! Please refer to our Contribution Guidelines if you want to get started.
Build OpenCloud
To build the backend, follow these instructions:
Generate the assets needed by e.g., the web UI and the builtin IDP
make generate
Then compile the opencloud binary
make -C opencloud build
That will produce the binary opencloud/bin/opencloud. It can be started as a local test instance right away with a two step command:
opencloud/bin/opencloud init && opencloud/bin/opencloud server
This creates a server configuration (by default in $HOME/.opencloud) and starts the server.
For more setup- and installation options consult the Development Documentation.
Technology
Important information for contributors about the technology in use.
Authentication
The OpenCloud backend authenticates users via OpenID Connect using either an external IdP like Keycloak or the embedded LibreGraph Connect identity provider.
Database
The OpenCloud backend does not use a database. It stores all data in the filesystem. By default, the root directory of the backend is $HOME/.opencloud/.
