O que é Dify?

Dify.ai é uma plataforma voltada para a criação de aplicações impulsionadas por inteligência artificial, como chatbots e assistentes virtuais. Ela oferece uma interface simples que permite aos usuários integrarem IA em seus projetos sem necessidade de habilidades avançadas de programação. Além disso, o Dify.ai facilita o uso de modelos de linguagem natural, como os desenvolvidos pela OpenAI, para melhorar interações automatizadas com usuários, promovendo soluções rápidas e eficientes para empresas e desenvolvedores.

Fazer os apontamentos no Zone DNS do tipo A para o IP da sua VPS:

  • appdify (backend)
  • apidify (api) dify (frontend)
  • portainer
  • www.portainer
  • traefik
  • www.traefik
  • edge
  • www.edge

Para criar sua senha htpasswd clique aqui:

https://packtypebot.com.br/gerador/htpasswd.php

sudo apt update && sudo apt install -y git && git clone https://github.com/mathuzabr/portainer-packtypebot.git && cd portainer-packtypebot && sudo chmod +x install.sh && ./install.sh

Antes de criar a stack no Portainer, crie uma network chamada “Dify” e atribua no Traefik, conforme eu ensino no vídeo.

Código da stack do Dify para copiar e colar no Portainer:
