Single-service previews: preview one service, not the whole stack
How previewing a single service works, when you want the web service previewed but not its database, and what preview environments Voroa offers today.
What this covers
A preview environment gives a pull request its own running copy of your service, at its own address, so a reviewer can click the change instead of reading a diff. The question that comes up next is how much of the rest of your stack comes with it. Copying everything, including the database, is slow and expensive; copying nothing means the preview has no data to work against. A single-service preview is the middle option: one service is rebuilt from the pull request branch, and everything else it talks to stays as it is.
Controlling which services a preview includes is not available on Voroa today. Preview environments themselves are covered by the guide below.
