Webserver

The webserver handles requests for qrank.wmcloud.org. It runs on the Wikimedia Cloud VPS infrastructure behind a reverse HTTP proxy.

Release instructions

We should set up an automatic release process, but are blocked on T194332. Meanwhile, here’s how to manually push a new version of the binary to the server.

GOOS=linux go build ./cmd/webserver
scp -J sascha@bastion.wmcloud.org ./webserver sascha@172.16.0.220:bin/webserver

On the server, we have the following configuration file in /etc/systemd/system/qrank-webserver.service. The redacted values of S3_KEY and S3_SECRET can be retrieved by ssh login.toolforge.org followed by become qrank and then toolforge envvars list.
