### Local cache

> [!WARNING]
>
> At the moment, old cache entries aren't deleted, so the cache size [keeps growing](https://github.com/docker/build-push-action/issues/252).
> The following example uses the `Move cache` step as a workaround (see [`moby/buildkit#1896`](https://github.com/moby/buildkit/issues/1896)
> for more info).

You can also leverage [GitHub cache](https://docs.github.com/en/actions/using-workflows/caching-dependencies-to-speed-up-workflows)
using the [actions/cache](https://github.com/actions/cache) and [local cache exporter](../../cache/backends/local.md)
with this action:
