Backend code for a D3 notary

D3 consists of 3 parts. Common services should be run obligatory and rest can be run optionally:

  1. Common services
  2. Ethereum subsystem

Common services

  1. Clone project master branch
  2. Launch Iroha and Postgres in docker with docker-compose -f deploy/docker-compose.yml -f deploy/docker-compose.dev.yml up
  3. Run registration service PROFILE=mainnet ./gradlew runRegistration
  4. (Optional) Run exchanger service PROFILE=mainnet ./gradlew runExchanger

Now you can register clients and launch subsystems.

How to run notification services

  1. Create SMTP configuration file located at configs/smtp.properties(see test example configs/smtp_test.properties). This file contains SMTP server credentials.
  2. Create Push API configuration file located at configs/push.properties(see test example configs/push_test.properties). This file contains VAPID keys. You can generate keys by yourself using webpush-libs tutorial.
  3. Run gralde command ./gradlew runNotifications

AWS SES Integration

SMTP configuration file configs/smtp.properties must be modified in order to be able to send email notifications via AWS SES.

smtp.host=email-smtp.eu-west-1.amazonaws.com
smtp.port=25
smtp.userName=ask maintainers
smtp.password=ask maintainers

Testing

./gradlew test for unit tests

./gradlew integrationTest for integation tests

Troubleshooting

  1. Services cannot be lauched due to the issue with protobuf. Solution for linux — use 3.5.1 version. Solution for mac — manually put old version in Cellar folder for 3.5.1 version (ask someone from the team), and link it with brew switch protobuf 3.5.1.

  2. Services cannot resolve their hostnames. Solution — add following lines to /etc/hosts file:

127.0.0.1 d3-iroha
127.0.0.1 d3-iroha-postgres
127.0.0.1 d3-notary
127.0.0.1 d3-eth-node0
127.0.0.1 d3-btc-node0
127.0.0.1 d3-rmq
127.0.0.1 d3-brvs
127.0.0.1 d3-brvs-mongodb
