Local gender-decoder running in a container

[desrod]

I've created a simple cloud-init that clones this repo, configures PostgreSQL + Flask, and spins up the gender-decoder in a local container.

We use this heavily to analyze our public-facing job postings, but those aren't always made public straight away, so we needed a way to analyze the posts in draft before publishing. This is also being used to analyze local collateral.

There are a few hard-coded values that point back to the public gender-decoder, I'll PR those and patch those out in the jinja2 templates to make those tunables (specifically, the referral link to the analyzed content).

The cloud-init YAML below will..

• Clone this repository's 'main' branch
• Create and configure a simple PostgreSQL user
• Install and configure the necessary Python dependencies of Flask
• Launch Flask with the application listening on port :5000

To create and run this:

1. Create a local container (username is ubuntu, password is ubuntu)

   uvt-kvm create gdecoder release=focal arch=amd64 --memory 4096 --cpu 2 --disk 20 --host-passthrough --user-data gender-decoder.yaml
   

2. Give the container a few minutes to spin up and configure the various pieces

3. Find the container's IP, so you can reach the gender-decoder on :5000, using:

   uvt-kvm ip gender-decoder
