Literate Computing has a new $1500 installation package for those who want a WordPress or Ghost site with Discourse in a sub-folder, or want to run multiple Discourse sites from a single container with a shared database. Prometheus and Grafana are included.
traefik is used as the reverse proxy, configured with Docker labels. This installation is a couple steps away from a Standard cloud install (managing the Docker labels that control Traefik’s routing is a bit tricky), and the package includes training to see that you know how to manage upgrades.
This configuration lets you have staging and production configurations (with different plugin sets) on a single server/droplet.
