"Importance of AI Prompt Management:

Consistency: Ensures consistent outputs across multiple interactions or users.
Efficiency: Saves time by reusing and refining effective prompts.
Performance optimization: Helps in fine-tuning prompts for better results.
Collaboration: Enables teams to share and improve prompts collectively.
Version control: Tracks changes and improvements in prompts over time.
Compliance: Helps maintain adherence to guidelines and ethical standards.

Issues in Prompt Management:

Versioning: Keeping track of different prompt versions and their effectiveness.
Organization: Managing a large number of prompts across various projects or use cases.
Sharing: Efficiently sharing prompts among team members or across departments.
Testing: Systematically testing and comparing different prompt variations.
Documentation: Maintaining clear records of prompt purposes, contexts, and performance.
Security: Ensuring sensitive prompts are not exposed to unauthorized users.
Scalability: Managing prompts as the number of AI applications and users grows.

How dify.ai can help:

Centralized repository: Provides a single location to store and organize all prompts.
Version control: Tracks changes to prompts over time, allowing for easy rollbacks if needed.
Collaboration features: Enables team members to work together on prompt development and refinement.
Testing and optimization: Offers tools to systematically test and compare different prompt versions.
Integration capabilities: Can potentially integrate with various AI models and platforms for seamless workflow.
User management: Allows for access control and permission settings for different team members.
Analytics: Provides insights into prompt performance and usage patterns.
Templating: Offers reusable prompt templates to maintain consistency across similar use cases.
API access: Likely provides API endpoints for programmatic access to prompts in applications.
Documentation: Facilitates adding context, notes, and performance data to each prompt.

@zonzonzon er, you didn't vote

For folks who need to self host this app, I created a comprehensive tutorial.

Create a fresh server, update and upgrade the system, install docker and docker compose with this one command.

sudo apt-get update -y &&
sudo apt-get upgrade -y &&
sudo apt-get install -y apt-transport-https ca-certificates curl software-properties-common gnupg lsb-release &&
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg &&
echo "deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null &&
sudo apt-get update -y &&
sudo apt-get install -y docker-ce &&
sudo usermod -aG docker $USER &&
sudo curl -L https://github.com/docker/compose/releases/download/v2.26.1/docker-compose-`uname -s-uname -m` -o /usr/local/bin/docker-compose &&
sudo chmod +x /usr/local/bin/docker-compose && \

Clone the Repo

git clone https://github.com/langgenius/dify.git

Customize the .env file

cd dify/docker
cp .env.example .env

I only customized the following variables.
APP_WEB_URL=your_domain_name
NGINX_HTTPS_ENABLED=true
NGINX_SSL_CERT_FILENAME=cert.pem
NGINX_SSL_CERT_KEY_FILENAME=key.pem

Ctrl S to save, Ctrl X to exit the nano editor.
cd -

Create SSL Certificate

Create ssl certificate at Cloudflare (open SSL/TSL tab and open Original Server)

nano dify/docker/nginx/ssl/cert.pem
Copy and paste the Cloudflare certificate, then Ctrl S, Ctrl X

nano dify/docker/nginx/ssl/key.pem
Copy and paste the Cloudflare SSL key, then Ctrl S, Ctrl X

Deploy

cd dify/docker
docker compose up -d

Upgrade

cd dify/docker
docker compose down
git pull origin main
docker compose pull
docker compose up -d

Setting Up Automated Backups for Dify Using Restic and Cloudflare R2

Step 1: Install Restic

Connect to your server via SSH.
Update your package list and install Restic:
```
sudo apt update
sudo apt install restic
```

Step 2: Prepare Your Cloudflare R2 Bucket

Create a new R2 bucket in your Cloudflare account if you haven't already.
Note down the following information from your Cloudflare R2 setup:
- Bucket name
- Access Key ID
- Secret Access Key
- R2 Endpoint URL

Step 3: Create the Backup Script

Create a new directory for the Restic script:
```
mkdir -p /root/restic
```
Create and open the backup script using nano:
```
nano /root/restic/backup.sh
```

Copy and paste the following content into the file:

#!/bin/bash

# Set environment variables for Restic
export RESTIC_REPOSITORY="s3:YOUR_R2_ENDPOINT_URL/YOUR_BUCKET_NAME"
export AWS_ACCESS_KEY_ID="YOUR_ACCESS_KEY_ID"
export AWS_SECRET_ACCESS_KEY="YOUR_SECRET_ACCESS_KEY"

# Set the backup source
BACKUP_SOURCE="/root/dify/docker/volumes"

# Perform the backup
restic backup $BACKUP_SOURCE

# Prune old snapshots (keep last 7 daily, last 4 weekly, and last 12 monthly backups)
restic forget --keep-daily 7 --keep-weekly 4 --keep-monthly 12 --prune

# Check the repository for errors
restic check

Replace the following placeholders with your actual Cloudflare R2 information:
- YOUR_R2_ENDPOINT_URL: Your Cloudflare R2 endpoint URL
- YOUR_BUCKET_NAME: Your R2 bucket name
- YOUR_ACCESS_KEY_ID: Your R2 Access Key ID
- YOUR_SECRET_ACCESS_KEY: Your R2 Secret Access Key
Save the file and exit nano:
- Press Ctrl + X
- When prompted to save, press Y
- Press Enter to confirm the file name
Make the script executable:
```
chmod +x /root/restic/backup.sh
```
Secure the script (as it contains sensitive information):
```
chmod 700 /root/restic/backup.sh
```

Step 4: Initialize the Restic Repository

Set the environment variables (replace with your actual R2 information):

export RESTIC_REPOSITORY="s3:YOUR_R2_ENDPOINT_URL/YOUR_BUCKET_NAME"
export AWS_ACCESS_KEY_ID="YOUR_ACCESS_KEY_ID"
export AWS_SECRET_ACCESS_KEY="YOUR_SECRET_ACCESS_KEY"

Initialize the Restic repository:
```
restic init
```

Step 5: Set Up Daily Backups

Open the crontab file:
```
crontab -e
```
If prompted to select an editor, choose nano by entering the corresponding number.
Add the following line at the end of the file to run the backup daily at 3 AM:
```
0 3 * * * /root/restic/backup.sh > /root/restic/backup.log 2>&1
```
Save the file and exit nano:
- Press Ctrl + X
- When prompted to save, press Y
- Press Enter to confirm

Verifying the Setup

To ensure everything is set up correctly:

Run the backup script manually:
```
/root/restic/backup.sh
```
Check the Restic repository for snapshots:
```
restic snapshots
```

Restoring from a Backup

To restore your data:

List available snapshots:
```
restic snapshots
```
Restore the latest snapshot:
```
restic restore latest --target /path/to/restore
```
Replace /path/to/restore with the directory where you want to restore the data.

Done.

Started a packaging attempt ...

That's a masterpiece

timconsidine

V0.0.1 installed on my Cloudron
Couple issues to resolve.
But

timconsidine

Released v0.0.2 of my cloudron-dify package.

Available on CustomAppGateway and/or your own CCAI-P app, if installed. Or one-liner installation :
curl -fsSL https://customappgateway.appx.uk/install.sh | bash -s -- --install-app "dify"

Still early days on cloudron deployment, but releasing it so early-adopters can help flush out issues.

It's a large docker image, so be patient with installation.

issues :

need to check email setup
need to actually use it !
Investigating the connection to Dify Marketplace (seems off)

timconsidine

released v0.0.6
plugin installation fixed for installing from local (just download from marketplace and then install the local plugin package file)

Investigating the direct marketplace link

Cloudron makes it easy to run web apps like WordPress, Nextcloud, GitLab on your server. Find out more or install now.
