The cache settings may also be set through environment variables. When set, environment variables override any `cache` config settings for Minio server. Following example uses `/mnt/drive1`, `/mnt/drive2` and `/mnt/drive3` for caching, with expiry upto 90 days while excluding all objects under bucket `mybucket` and all objects with '.pdf' as extension while starting a standalone erasure coded setup.
