blitz.cloud docs
How to deploy Docker images, GitHub projects, one-click apps and managed databases on blitz.cloud, the European hosting platform run by BlitzWorks.
blitz.cloud hosts apps under an address you own, like photos.lena.blitz.cloud. Today you can install one of the apps in the App Store, run any public Docker image from Docker Hub or another public registry, or build a project from GitHub. Any public project builds from its link. Connect GitHub and your own projects build too, private ones included, with a new version online on every push. Each app can have a managed database and gets HTTPS without you setting anything up.
To follow an app once it runs, read app status and logs: the Activity tab with earlier versions to put back, uptime and traffic, and the mails we send when something happens.
