# Digital Factory Demo 3.3 - Installation

## Overview

Digital Factory Demo (DFD) 3.3 installs from a single self-installing container. You load one image and run it; it brings up the full stack inside Litmus Edge
(`simulation_servers`, `mssql`, `mysql`, `grafana`, `template-applyer`), and `template-applyer` configures Litmus Edge automatically: devices, tags, flows, digital twins,
integrations, and SQL connectors. There is no separate template file to upload.

There are two installers:

- **Online** (`demo_install`): small download; pulls the stack images from `litmusedge.azurecr.io` at run time.
- **Offline** (`demo_install_offline`): bundles every image; no registry access needed at deploy time.

A short post-install step is still required to enter the database credentials inside the flow nodes (these are not carried by the template).

## Prerequisites

- Litmus Edge 3.16.x or later
- A valid Litmus Edge license
- About 5 GB free disk and 3 GB RAM headroom
- Docker access on the Litmus Edge host

## Online install

### 1. Download

From the Litmus central portal (Digital Factory Demo solution), download the file marked "online": `Files_For_ONLINE_Installation_v3.3.zip`. Unzip it to get
`demo_install.tar.gz`.

### 2. Log in to the registry

The host needs to pull the stack images:

```bash
docker login litmusedge.azurecr.io
```

### 3. Load and run the installer

```bash
docker load -i demo_install.tar.gz

docker run -d --rm \
  -v /var/run/docker.sock:/var/run/docker.sock \
  -e EDGE_API_TOKEN=init \
  -e EDGE_URL=172.172.0.1:8443 \
  litmus/demo_install:latest
```

`EDGE_API_TOKEN=init` auto-generates a token on first login. Allow 3 to 5 minutes for images to pull and the stack to start.

## Offline install

### 1. Download

From the central portal, download the file marked "offline": `Files_For_OFFLINE_Installation_v3.3.zip` (about 1 GB). Unzip it to get `demo_install_offline.tar.gz`.

### 2. Load and run the installer

```bash
docker load -i demo_install_offline.tar.gz

docker run --rm \
  -v /var/run/docker.sock:/var/run/docker.sock \
  -e EDGE_API_TOKEN=init \
  -e EDGE_URL=172.172.0.1:8443 \
  litmus/demo_install_offline:latest
```

The installer loads all bundled images into Litmus Edge, so no pull happens. Allow a few minutes for the stack to start.

## Post-install configuration

After the stack is up and the installer has exited, complete these steps in the Litmus Edge UI.

### 1. Enter database credentials in flows

Go to **Flows** and open the production, maintenance, and energy-monitoring flows. In the **Global Code Matrix** tab, open each database node (the query and insert-record
nodes) and enter the SQL credentials (`sa` / `Demo1234`). Deploy the flows after editing.

### 2. Add the InfluxDB database user

Go to **DataHub > DB Users** and add a user to the internal Litmus Edge database (`tsdata`) so the InfluxDB node can write time-series data.

### 3. Enable the device data store

Go to **DeviceHub > Devices**, enable **Data Store**, and set retention to 24 hours. Click **Update Device** for each device.
