Builder

The builder tool is a cronjob that computes osmviews.tiff and osmviews-stats.json from OpenStreetMap tile log impressions.

Release instructions

We should set up a fully automatic release process, but are blocked on Wikimedia T194332. Currently, a GitHub action automatically builds and tests a release candidate whenever a git tag gets pushed to the repository. However, to become live, the binary still needs to be deployed to production. Note that this will update both the backend pipeline and the web server.

$ ssh bastion.toolforge.org
$ become osmviews
$ python3 prod/deploy_release.py latest  # either 'latest' or tag like '0.0.2'
