Provides an unauthenticated plain HTTP frontend for public and private S3 buckets, and caches on the filesystem. Least Recently Used objects are evicted from the cache first.

Example:

  python setup.py install
  export AWS_ACCESS_KEY_ID=...
  export AWS_SECRET_ACCESS_KEY=...
  caching-s3-proxy &
  curl localhost:8000/org.mozilla.crash-stats.symbols-private/v1/symupload-1.0-Linux-20120709194529-symbols.txt

If you want to listen on a different port, just set the PORT variable:

  PORT=9999 caching-s3-proxy

You can also set CAPACITY (in bytes) and CACHEDIR.

Alternatively, you can run under uwsgi. It's safe to use multiple workers processes (the shared file cache uses file locking to allow concurrency):

  uwsgi -w proxy.wsgi --http=localhost:8000 --workers=10

If you want to put this behind Nginx or Apache, use a socket instead:

  uwsgi -w proxy.wsgi -s /var/run/caching-s3-proxy.sock --workers=10
