List of Amazon S3 API's not supported on MinIO

We found the following APIs to be redundant or less useful outside of AWS S3. If you have a different view on any of the APIs we missed, please consider opening a GitHub issue with relevant details on why MinIO must implement them.

List of Amazon S3 Bucket API's not supported on MinIO

  • BucketACL (Use bucket policies instead)
  • BucketCORS (CORS enabled by default on all buckets for all HTTP verbs, you can optionally restrict the CORS domains)
  • BucketWebsite (Use caddy or nginx)
  • BucketAnalytics, BucketMetrics, BucketLogging (Use bucket notification APIs)

List of Amazon S3 Object API's not supported on MinIO

Object name restrictions on MinIO

  • Object name restrictions on MinIO are governed by OS and filesystem limitations. For example object names that contain characters ^*|\/&"; are unsupported on Windows platform or any other file systems that do not support filenames with special charaters.

This list is non exhaustive, it depends on the operating system and filesystem under use - please consult your operating system vendor for a more comprehensive list of special characters.

MinIO recommends using Linux operating system for production workloads.

  • Objects must not have conflicting objects as parent objects, applications using this behavior should change their behavior and use non-conflicting unique keys, for example situations such as following conflicting key patterns are not supported.
PUT <bucketname>/a/b/1.txt
PUT <bucketname>/a/b

PUT <bucketname>/a/b
PUT <bucketname>/a/b/1.txt
