A Drone plugin for caching current workspace files between builds to reduce your build times. drone-cache is a small CLI program, written in Go without any external OS dependencies (such as tar, etc).
With drone-cache, you can provide your own cache key templates, specify archive format (tar, tar.gz, etc) and you can use an S3 bucket or a mounted volume as storage for your cached files, even better you can implement your own storage backend to cover your use case.
For detailed usage information and a list of available options please take a look at usage and examples. If you want to learn more about custom cache keys, see cache key templates.
If you want to learn story behind it, you can read our blogpost!
drone-cache stores mounted directories and files under a key at the specified backend (by default S3).
Use this plugin to cache data that makes your builds faster. In the case of a cache miss or zero cache restore it will fail silently in won't break your running pipeline.
The best example would be to use this with your package managers such as Mix, Bundler or Maven. After your initial download, you can build a cache and then you can restore that cache in your next build.
With restored dependencies from a cache, commands like mix deps.get will only need to download new dependencies, rather than re-download every package on each and every build.
The following .drone.yml configuration show the most common use of drone-cache.
Note: These configs use drone 1.0 syntax. If you are using drone 0.8, check the examples in docs/examples/drone-0.8.md.
