Run the following commands:
heroku create
heroku buildpacks:add heroku/gradle
git push heroku master
curl https://your-app-123456.herokuapp.com/getAllMarketPrices
To register the node as a Tor hidden service, first install the Heroku Tor buildpack:
heroku buildpacks:add https://github.com/cbeams/heroku-buildpack-tor.git
git push heroku master
NOTE: this deployment will take a while, because the new buildpack must download and build Tor from source.
Next, generate your Tor hidden service private key and .onion address:
heroku run bash
./tor/bin/tor -f torrc
When the process reports that it is "100% bootstrapped", kill it, then copy the generated private key and .onion hostname values:
cat build/tor-hidden-service/hostname
cat build/tor-hidden-service/private_key
exit
IMPORTANT: Save the private key value in a secure location so that this node can be re-created elsewhere with the same .onion address in the future if necessary.
Now configure the hostname and private key values as environment variables for your Heroku app:
heroku config:set HIDDEN=true HIDDEN_DOT_ONION=[your .onion] HIDDEN_PRIVATE_KEY="[your tor privkey]"
git push heroku master
When the application finishes restarting, you should still be able to access it via the clearnet, e.g. with:
curl https://your-app-123456.herokuapp.com/getAllMarketPrices
And via your Tor Browser at:
http://$YOUR_ONION/getAllMarketPrices
