Deploy to Heroku

[milesfrain]

Inspired by the instructions at the deprecated JuliaHerokuEndpoint, I'm attempting to deploy this to Heroku.

This is a similar situation to the report on Julia Discourse, but I'm using your repo here, rather than mine. The outcomes are similar. The container runs fine locally, but fails in Heroku. The errors in each case are slightly different.

Here are the commands I'm using for this repo:

git clone https://github.com/amellnik/Joseki.jl.git
cd Joseki.jl
HEROKU_APP_NAME="joseki-example"
heroku create $HEROKU_APP_NAME
heroku container:push web --app $HEROKU_APP_NAME
heroku container:release web --app $HEROKU_APP_NAME
heroku logs --tail --app $HEROKU_APP_NAME

Here are the generated errors:

The command to run the container locally, which works fine:

docker run --rm -p 8000:8000 registry.heroku.com/$HEROKU_APP_NAME/web

Got this working using buildpacks. Updated my example repo to show the necessary steps.
