OpenSirene

OpenSirene is a REST micro-service to build and access a database of French companies provided by the French government's open data.

This micro service will run a crontab to downloads automatically update files and save them to a PostgreSQL database.

API contract

API endpoints are defined using a Swagger file at the root of the Git repository.

Search endpoints:
- GET /api/v1/siret/{siret_id}
  - Retrieve one company from its SIRET identifier
- GET /api/v1/siren/{siren_id}
  - Retrieve the list of establishments of a company from its SIREN identifier
Monitoring endpoints:
- GET /admin/ping
  - For monitoring purpose
- GET /admin/history
  - Retrieve the list of update files stored in database

Setup

The micro service needs 10Gb of free space to manipulates update files and the database server approximately the same to store them.

With Docker Compose

For development only, it will start two containers: the database (PostgresSQL) and the micro-service.

$ docker-compose up
$ curl localhost:8080/ping

With Debian package (for production environment)

# Download and install
$ LATEST_VERSION="1.2.1"
$ wget https://github.com/jclebreton/opensirene/releases/download/${LATEST_VERSION}/opensirene_${LATEST_VERSION}_amd64.deb
$ wget https://github.com/jclebreton/opensirene/releases/download/${LATEST_VERSION}/SHA256SUMS
$ sha256sum -c SHA256SUMS
$ dpkg -i opensirene_${LATEST_VERSION}_amd64.deb

# Create the configuration file and edit it with your own configuration
$ mkdir /etc/opensirene/
$ cp /usr/share/opensirene/conf-example.yml /etc/opensirene/conf.yml
$ vi /etc/opensirene/conf.yml

# Start service
$ systemctl start opensirene
$ systemctl daemon-reload # if needed

# Check if the service is up
$ systemctl status opensirene
$ curl 127.0.0.1:8080/ping

To redirect logs to syslog, edit /lib/systemd/system/opensirene.service and add those lines to the end:

StandardOutput=syslog
StandardError=syslog
SyslogIdentifier=opensirene

Build and run

$ go get -u github.com/golang/dep/cmd/dep
$ dep ensure
$ go run main.go --config=conf-example.yml

Configuration

This project can be configured using both a yaml configuration file and environment variables (for most of the configuration fields). Environment variables have a higher priority than the configuration file, which means you can override almost any value of the configuration file using them.

Example

  level: debug

  prefix:
    api: "/api/v1"
    admin: "/admin"

database:
  user: xx

  name: opensirene
  host: 127.0.0.1
  port: 5432
  sslmode: disable

prometheus:
  prefix: opensirene
