Fulfilment for an api.ai -powered Actions on Google integration that provides live departure times through a Google Home.
This is deployed and live! If you have a Google Home, ask activate it by saying
Hey Google, let me talk to Tube Trains.
You can also ask it in one go:
Hey Google, ask Tube Trains about the next departures from Euston Square.
Or something a bit more involved:
Hey Google, at Tube Trains, tell me about the next eastbound departures on the Hammersmith & City Line from Aldgate East.
You can see it in action here:
You can also find it under the available services in the Google Home app:
Automated testing is limited at this point, types have provided sufficient help so far.
Some limited test fixtures are available for manual testing:
stack build
stack exec tube-bot-fulfillment
curl -vv 'http://localhost:8001/webhook' -XPOST -H "Content-Type: application/json" -d @data/test_req.json
There's also a small test suite you can run with stack test.
There's a Docker image for easier deployment, which simply wraps a statically linked binary.
In order to build the container, please first build the static binary.
./build-static.sh
docker build --rm -t passy/tube-bot-fulfillment:vx.y.z .
docker push passy/tube-bot-fulfillment:vx.y.z
Alternatively, if building statically through the provided container doesn't work
(OOM errors or linking issues due to outdated upstream), you can build via
stack build --docker after adding ld-options: -static to the executable section
in package.yaml. If this turns out to be the overall more reliable way, I'll
change the script accordingly.
I use this docker-compose config file that I check out and run on my VPS. Maybe that'll do for you as well.
