Set a Base Preview

Whether you want to set one Base Preview, or set multiple Base Previews, the process is the same:

How to set a Base Preview

To create a Base Preview, you’ll first need to have a Preview build to serve as your starting point.

  1. Go to username -> My Projects at the upper-right of the Tugboat screen.
  2. Select the project where you want to set a Base Preview.
  3. Click the name of the repo that contains Preview you want to use as a Base Preview.
  4. Go to the Manage Base Previews link on the Repository Dashboard.
  5. Click the checkbox next to the Preview you want to use as a Base Preview.
  6. Press the OK button.

That preview will be moved to the Base Preview

section of the Repository Dashboard. From now on, Previews will build from the snapshot created when the Base Preview was built.

Add multiple Base Previews

To set more than one Base Preview, follow the directions above, but check the checkboxes next to all of the Previews that you’d like to set as Base Previews when you get to Step 5.

Set multiple Base Previews

When you’ve selected multiple Base Previews, every new Preview build (including automated builds from pull requests) will create a build from each Base Preview. In my sample project, I’ve set two base Previews, and building a Preview from a new PR automatically created two Previews - one for each Base Preview.
