Action Summary

The Rust Cache S3 Action is a GitHub Action that accelerates Rust project builds by caching dependencies and build artifacts, with added support for S3-compatible storage solutions like AWS S3, MinIO, and RustFS. It automates cache management, enabling seamless integration with both GitHub-hosted and self-hosted runners while offering flexibility to switch between different cache providers. This action optimizes build times and resource usage by leveraging efficient cache storage mechanisms tailored to diverse infrastructure setups.

Release notes

Fork of Swatinem/rust-cache with S3-compatible storage support.

What’s New

  • S3 cache provider — routes cache operations to S3-compatible backends (RustFS, MinIO, AWS S3)
  • Auto-detection — automatically activates when RUNS_ON_S3_BUCKET_CACHE env var is set; no workflow changes needed
  • Explicit opt-in — set cache-provider: s3 to force S3 mode
  • All original providers (github, buildjet, warpbuild) remain unchanged

Configuration

S3 is configured via environment variables:

VariablePurpose
RUNS_ON_S3_BUCKET_CACHEBucket name (presence triggers S3 mode)
RUNS_ON_S3_BUCKET_ENDPOINTCustom endpoint for self-hosted S3
RUNS_ON_S3_FORCE_PATH_STYLESet true for RustFS/MinIO
