For my reader app I am using cronjobs to schedule my a new build and upload to
cloudflare pages every hour.  In this example I have built a docker image
`docker.io/waylonwalker/reader-waylonwalker-com` and pushed it to dockerhub.
It uses a `CLOUDFLARE_API_TOKEN` secret to access cloudflare, and the
entrypoint itself does the build and upload.
