Cache settings

The shared cache is on by default. An admin can change it in the Shared cache tab on the Runners page of the Trunk web app. This page shows the settings and who can change them.

Where the settings apply

The tab shows one row for the Organization default and one row for each repository override. To change a row, click Edit.

Level	What it controls
Organization default	The settings for every repository.
Repository override	The settings for one repository.

Globally Disable Cache - From the Shared Cache screen admins can disable all cache functionality for your Trunk Runners.

Which branches a job uses cache from

Value	A job uses cache entries from
This branch and default	Its own branch and the default branch.
All branches	Its own branch and the default branch, then any other branch in the repository.

With either value, a job writes only to its own branch. For Bazel, the setting applies to the action cache.

With All branches, a person who can push a branch can change what the default branch builds. Keep This branch and default for a repository that releases from its default branch. For Nix, keep it if you deploy from Nix builds.

When a change applies

Trunk reads the settings when a job starts. A job that already started keeps its settings until it ends.
