This is the main repository of the OpenCloud server. It contains the golang codebase for the backend services.

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.

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.

Important information for contributors about the technology in use.

The OpenCloud backend authenticates users via OpenID Connect using either an external IdP like Keycloak or the embedded LibreGraph Connect identity provider.

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/.
