Langflow on Ubuntu 24.04 LTS by cloudimg

## Langflow on Ubuntu 24.04 LTS by cloudimg

Langflow is the open-source, low-code visual builder for AI agents and retrieval-augmented-generation (RAG) applications. Design flows by dragging and connecting components on a canvas, test them interactively, and serve them as APIs. The cloudimg image installs Langflow 1.9 in a Python virtual environment, fronts it with an nginx reverse proxy on port 80, and generates a unique administrator password and Fernet credential-encryption key on the first boot of every VM. Backed by 24/7 expert support.

Dedicated Data Disk

The SQLite database, saved flows, uploads and the credential-encryption key live on a dedicated, independently resizable Azure data disk mounted at /var/lib/langflow, kept separate from the operating system disk and re-provisioned with every VM. Snapshot that disk to back up your flows.

Secure By Default

The administrator password is unique per VM and stored in a root-only file; the credential-encryption key is a valid Fernet key generated on first boot. nginx fronts the loopback Langflow service so only port 80 is exposed; front it with TLS for public access.
