Langflow on Ubuntu 24.04 LTS

Langflow is a visual builder for LLM applications: drag-and-drop chains, agents, and RAG pipelines on top of LangChain. This image gives you a production-ready deployment within minutes of first boot — no dependency wrangling, no manual hardening checklist. Published and maintained by Derek Coleman & Associates Inc: freshly rebuilt against current security advisories and deployable straight from the Azure Marketplace into your own subscription.

Version: Langflow 1.12.4 (Python 3.12 venv)Platform: Ubuntu 24.04 LTSPorts: 7860 (web UI)Category: Applications

What's included

Langflow 1.12.4 installed from the official upstream source
Ubuntu 24.04 LTS base with automatic security updates enabled
No shared or default passwords — a unique admin credential is generated on your VM at first boot
Trusted Launch support: Secure Boot + vTPM
Azure Monitor Agent, Defender for Cloud, and Update Manager install cleanly

Quick start

Deploy from the Azure Marketplace (Get It Now → Create), choosing your SSH key at the Administration step.
Allow inbound SSH (22) for yourself plus the application port(s): 7860 (web UI) — restrict to your own IP where possible. The in-image firewall already allows them; only the Network Security Group (NSG) keeps them closed.
Open http://<VM-IP>:7860/ and sign in as dcaadmin (see First login below).
Add your model provider keys in Settings → Global Variables and build your first flow.

Get your admin password (one time)

ssh <your-username>@<VM-IP>
sudo cat /var/lib/langflow/admin-password

Sign in as dcaadmin with the password in the file. Langflow allows 5 sign-in attempts per minute per client address; the next one is answered with HTTP 429 — wait a minute and try again.

Common use cases

Prototyping LLM chains and agents visually
RAG pipelines over your own data
Internal AI assistants and chatbots
Experimenting with prompts and models

Why our images
