# Bucket Policies Bucket policies apply to buckets and determine the read/write access to them. This is especially useful for allowing anonymous access of various kinds. ## Policies The following policies are available: * fetchonly.json: Similar to ReadOnly in that it allows fetching any object in the bucket anonymously. The difference is that it does not allow *listing* bucket objects, meaning that the object name must be known ahead of time. ## Using Apply these policies as so: 1. Download the file. 2. Edit the file, replacing BUCKETNAME with the name of your bucket. 3. `mcli policy set-json ./FILE.json MYMINIO/BUCKETNAME`
