image-service

GRPC service demonstrating image upload using chunking technique over grpc streams.

Worth noting information about imgur

• read their rules
• all the images are public
• default cache is 1 year (cache-control=31536000)

Getting started

1. Generate an application on Imgur API here

2. Create a .env at the root of this project with the credentials:

   IMGUR_CLIENT_ID=xxxxxxx
   IMGUR_CLIENT_SECRET=xxxxxxx
   

3. You can find in this repo a simple Makefile that might work by just running make if you have the following requirements already installed:

• make
• python3
• poetry
• grpc-tools
• docker
• docker-compose

TODO

1. Sync the upload info to a database.

   create database image_service;
   -- \c image_service;

       id bigserial primary key,
