Nextcloud — Harp

The Reykjavik teens saw the Paris folder appear: [HISTORIC] The Lost Chorale of Oaxaca (Restored) . They pulled the sonograms and transcriptions into their own Loom. Within a week, they had created a new track: "La Llorona 2084 (Geothermal Mix)," which used the original 1930s field recording as a ghostly undertone to a pounding electronic beat.

Select for typical Docker setups, or "HaRP Proxy (Docker)" if running within a custom network, as shown in the Nextcloud Documentation .

Define the HaRP image (check the Nextcloud GitHub for the latest specific image tags).

The system automatically generates the necessary certificates for FRP communications, ensuring secure tunnels by default. harp nextcloud

HaRP replaces the older DockerSocketProxy setup with a single, easy‑to‑use container. Instead of configuring multiple moving parts, you deploy one container, set a shared secret, and point your reverse proxy at it. The GitHub documentation describes it as replacing “more complex setups with an easy‑to‑use container” – and that simplicity is a genuine advantage for administrators who want to get ExApps running without spending hours debugging proxy rules.

HaRP introduces several architectural improvements over its predecessor:

She read the final conversation:

Using Fast Reverse Proxy (FRP) tunnels, ExApp containers do not need to expose ports to the host or be directly reachable from the main Nextcloud server. This enables easier NAT traversal and deployment on remote hosts, such as specialized GPU servers for AI workloads.

The harp is one of the oldest instruments in human history, dating back to Mesopotamia and Ancient Egypt. It is a mechanism of tension and resonance. A harp only functions when its strings are pulled taut; it requires a structure—a frame—to hold that tension. Without the frame, the strings are limp and silent. Without the strings, the frame is a hollow skeleton.

Update your main reverse proxy (e.g., Nginx, Apache) to redirect specific app requests to the HaRP container. The Reykjavik teens saw the Paris folder appear:

fn append_metadata(prev_hash: &[u8; 32], meta: &Metadata) -> [u8; 32] let mut hasher = Sha3_256::new(); hasher.update(meta.serialize()); hasher.update(prev_hash); hasher.finalize().into()

Think of HaRP as a high-performance bridge that efficiently routes requests between users, your Nextcloud server, and the external apps that extend its functionality.

For setups behind Apache, additional configuration is required. Here's a proven configuration based on community experience: Select for typical Docker setups, or "HaRP Proxy
