Add Docker support

[spacepirate0001]

Add Docker build to containerize the project.

Did this work for you? I believe the standard is Dockerfile not dockerfile I get several errors:

info  - Linting and checking validity of types...
/usr/share/gpt4-pdf-chatbot-langchain/config/pinecone.ts:6
  throw new Error('Missing Pinecone index name in .env file');
        ^

Error: Missing Pinecone index name in .env file

    at ModuleJob.run (node:internal/modules/esm/module_job:192:25)

ENV vars are set and still doesn't seem to grab them :s

A docker-compose.yml would also make the experience simplier:

version: '3'

services:
  gpt4-pdf:
    container_name: gpt4-pdf
    build:
      context: .
      dockerfile: Dockerfile
    ports:
      - 3070:3000
    environment:
      OPENAI_API_KEY: WRITE_YOUR_OPENAI_KEY_HERE
      PINECONE_API_KEY: WRITE_YOUR_PINECONE_API_KEY_HERE
      PINECONE_ENVIRONMENT: WRITE_YOUR_PINECONE_ENV_HERE
      PINECONE_INDEX_NAME: WRITE_YOUR_PINECONE_INDEX_NAME_HERE
    volumes:
      - .:/usr/share/gpt4-pdf-chatbot-langchain

I have this running in cloudrun as of a few days ago which may help contribute back to see the setup.

I actually saw this one and it helped me quite a bit craft it all to work in Cloudrun nicely. In Vercels it times out for me, although GAIB may be different in that regard than this chatbot GAIB evolved out of.
