December 16, 2024

A recap on Python AI Apps that I have been working on during 2024.

The goal of this post is:

To review some of the AI projects that are helpful on my workflow
To learn how to use Caddy as NGINX/Traefik alternative to get HTTPs certificates

DNS challenge | Via PorkBun | Example 📌

As seen during the Flask Setup post on a VPS.

AI Apps

YT Summarizer

https://github.com/JAlcocerT/phidata
https://jalcocert.github.io/JAlcocerT/summarize-yt-videos/
Get your Groq API for the app https://console.groq.com/keys

Streamlit MultiChat

https://github.com/JAlcocerT/Streamlit-MultiChat
https://jalcocert.github.io/JAlcocerT/create-streamlit-chatgpt
Get (at least) OpenAI API for this app - https://platform.openai.com/api-keys

Streamlit MultiChat

ℹ️

People out there is doing way cooler projects, like LibreChat

And you will just need to:

Get docker/podman installed
Get the API’s
[Optional] Install Portainer

HTTPS with Caddy

The caddyfile normally serves to create HTTPs with Let’s Encrypt and DNS Challenge.

See http challenge method vs DNS Challenge method

See how I have applied these for the Streamlit Multichat: https://github.com/JAlcocerT/Docker/tree/main/AI_Gen/Project_MultiChat

Conclusion

Feature	Traefik	Nginx	Caddy
Ease of Use	High	Medium	High
Performance	Medium	High	Medium
Flexibility	High	High	Medium
Dynamic Configuration	Excellent	Requires more manual configuration	Supports some dynamic configuration
HTTPS Support	Good	Requires manual configuration	Excellent
Learning Curve	Medium	High	Low

Choose Traefik if: You prioritize automatic service discovery and a wide range of plugins.
Choose Nginx if: You need maximum performance and flexibility, even if it means a steeper learning curve.
Choose Caddy if: You value simplicity and ease of use, especially for HTTPS setup.

Caddy Strengths:
- Simplicity: Known for its user-friendly configuration syntax, making it easier to learn and use compared to Nginx.
- Automatic HTTPS: Supports automatic HTTPS certificate acquisition and management, simplifying security setup.
- Plugins: Offers a growing ecosystem of plugins for various functionalities.
Weaknesses:
- Performance: While generally performant, it may not match Nginx’s raw performance in very high-traffic scenarios.
- Maturity: While gaining popularity, it’s not as mature or widely used as Nginx.

I have tried Caddy with a OVH VPS Server with 2GB RAM.

Similar to the one in which I tried to deploy Wireguard (~300/1.88GB) RAM

ssh ubuntu@57.128.public.ip

Using NGINX with a VPS to deploy FLASK

https://github.com/NginxProxyManager/nginx-proxy-manager
https://fossengineer.com/selfhosting-nginx-proxy-manager-docker/
Strengths:
- High Performance: Known for its exceptional performance and scalability, making it suitable for high-traffic environments.
- Flexibility: Highly configurable and customizable, allowing for fine-grained control over traffic routing and other aspects.
- Mature and Widely Used: A well-established and widely used reverse proxy with extensive community support and documentation.
Weaknesses:
- Steeper Learning Curve: Configuration can be more complex and require more technical expertise compared to Traefik or Caddy.
- Less Automatic: Requires more manual configuration compared to Traefik’s dynamic discovery.

More about Caddy Reverse Proxy 📌

How to set up a reverse proxy and automatically enable SSL using Caddy and Docker Compose.

Key Steps:

Environment Setup:
- Create a directory and a Caddyfile for configuration.
- Use Docker Compose to manage containers, networks, and configurations.
- Define a Docker network for containers.
Caddy Configuration:
- Configure the Caddyfile with email, domain, and reverse proxy settings.
- Enable SSL certificates using Let’s Encrypt.
Network and DNS:
- Open necessary ports (80 and 443) on the network.
- Configure DNS with a wildcard host or specify each subdomain.

Benefits:

Efficiently manage multiple containers/applications on a single domain.
Automatically enable SSL certificates for secure connections.
Flexible DNS configuration options (wildcard or specific subdomains).
