This follows the official installation instructions at https://github.com/openbikesensor/portal/blob/main/docs/production-deployment.md
Unfortunately, the postgres database needs to have postgis enabled, so
we'll have to start a second instance. To stay close to the official
deployment instructions, this is running in docker.
The secrets were taken from the old installation instance. During
initial installation, we'll need to import data from the old instance
into this one, which might take a while.
