Before you start
To be hosted on GOV.UK PaaS, your app must:
- follow the twelve-factor application principles; this will be true if your app has been written so it can deploy to another PaaS like Heroku
- store data classified up to ‘official’; your app cannot store data classified as ‘secret’ or ‘top secret’
- be built using a supported buildpack or written in one of these languages:
- .NET Core
Cloud Foundry buildpacks provide runtime and framework support for your application. For most languages, you will need to provide configuration files to describe your app’s dependencies. Most buildpacks will support a limited range of versions of the language.
