Langflow AI Platform & Data · Langflow 1.13.0 Launch on AWS

Operations

This page covers day-to-day care of Langflow 0.2.1: access, backups, moving to another image, and support.

Security model

  • Loopback editor. The UI is on 127.0.0.1:7860. You open it through Session Manager or an SSH tunnel. Leave port 7860 closed to inbound traffic.
  • Administrator login. First boot creates /etc/langflow/admin.json. Signup and automatic login are off.
  • Encryption and identity. /etc/langflow holds the original encryption material and the administrator identity. Generating a replacement key can make stored credentials unreadable.
  • Your provider key. You add it after launch in a mode 0600 file. Flow exports can contain provider configuration. Inspect an export before you share it.

Status and logs

sushi-langflow status
sudo journalctl -u langflow.service --no-pager -n 100
sudo systemctl restart langflow.service

Backups

Stop Langflow before a filesystem backup, or take a consistent SQLite snapshot. Back up these together:

  • /var/lib/langflow (including langflow.db)
  • /etc/langflow (including service.env, admin.json, initialized.json, and any operator.env)

Restore the database with its original encryption and administrator configuration. Keep the backup until you have opened the editor and run a flow you trust.

Updates

A new Marketplace version is a new image. Keep a consistent backup, launch the replacement, and restore /var/lib/langflow and /etc/langflow together. Do not create a second administrator identity as a substitute for that backup.

Support

Software Sushi provides packaging and setup guidance. Email info@softwaresushi.com with the Marketplace version, the Region, and what you ran. Do not include admin.json, the encryption material, or the provider key.

The software rate on the listing is USD 0.03 per running instance-hour. EC2, EBS, data transfer, and model-provider calls are separate. Support beyond installation questions needs a separate agreement. Upstream Langflow support is not included. See Software Sushi for the company site.
