roki-demo

Setup

Install pip for python dependencies

pip install pipenv --user

Launch

Launch the docker containers

docker-compose up

Send some requests request

pipenv run python demo.py

The docker-compose will launch:

• a container with roki that can be reached on localhost:3000
• a container with simple http server that provides realtime gtfs-rt feeds to roki
• a prometheus server that scrapes metrics from roki. Its user interface is served on locahost:9090
• a grafana server with some dashboards that display the prometheus metrics. Go to locahost:3010. The initial login/password is admin/admin. It takes a minute or so to setup on first launch.

Roki expect protobuf requests sent via http, and respond with a protobuf payload. The protobuf schema for requests and responses are given in the roki.proto file in roki-proto/roki.proto

Look at the demo.py an the protobuf file to understand how requests are made, and how responses should be read.

The web interface https://pbench.github.io/roki-demo/ allows to make requests to your roki container.

Get more recent gtfs data

The gtfs datasets and gtfs-rt feeds present here were retrieved on 2024-11-21 (a day with a lot of snow and a strike) from https://transport.data.gouv.fr/

You can download more recent dataset by running

./download_gtfs.sh

This will replace the files data/tgv.zip data/ter.zip and data/intercites.zip

You can setup roki to retreive the most recent gtfs-rt feed by replacing the path http://gtfs_rt_feed_server:8001 in data/roki_config.toml by https://proxy.transport.data.gouv.fr/resource/

Configure roki

Roki reads its configuration from the data/roki_config.toml file. This file contains documentation for the configuration options.

Update the protobuf files

Install the protobuf compiler

sudo apt install -y protobuf-compiler

Generate the python protobuf files

protoc --proto_path=roki-proto --python_out=. roki-proto/roki.proto
