Applications often need a shared place to store files, backups or other large objects rather than putting them inside a database. MinIO provided a storage server with an S3-compatible interface, allowing clients built around that API to use storage operated by the team. This entry covers the original community distribution, whose repository is now retired. Existing users need to choose a supported continuation or replacement while preserving the object behavior their applications rely on.
Current guidance
The minio/minio open-source repository was archived in April 2026 and explicitly says it is no longer maintained.
The maintainer notice points to AIStor editions. Treat this as a distribution, support and licensing decision for the exact workload, not a generic chart upgrade. Other S3-compatible stores and managed services are alternatives requiring their own compatibility review.
Inventory clients, object metadata, versioning, lifecycle rules, access policy and recovery needs. Test reads and writes against a copy, then define how new objects are synchronized during cutover and rollback. An S3-compatible API label alone does not establish equivalent operations or data durability.

Minio is a lightweight, AWS S3 compatible object storage server. It is best suited for storing unstructured data such as photos, videos, log files, backups, VM and container images. Size of an object can range from a few KBs to a maximum of 5TB. Minio server is light enough to be bundled with the application stack, similar to NodeJS, Redis and MySQL.
Minio supports distributed mode. In distributed mode, you can pool multiple drives (even on different machines) into a single object storage server. This chart bootstraps Minio deployment on a Kubernetes cluster using the Helm package manager.
Prerequisites
- Kubernetes 1.4+ with Beta APIs enabled for default standalone mode.
- Kubernetes 1.5+ with Beta APIs enabled to run Minio in distributed mode.
- PV provisioner support in the underlying infrastructure.
Features
Amazon S3 Compatible
Amazon S3 API is the de facto standard for object storage. Minio implements Amazon S3 v2/v4 API. Use Minio SDK, Minio Client, AWS SDK, and AWS CLI to access Minio server.
Data Protection
Minio protects data against hardware failures using erasure code and bitrot detection. You may lose up to half the number of drives and still recover from it. Data protection code is accelerated using SIMD instructions on x64 and ARM CPUs.
Highly Available
Minio server can tolerate up to (N/2)-1 node failures in a distributed setup. In addition, you may configure Minio server to continuously mirror data between Minio and any Amazon S3 compatible server.
Lambda Compute
Minio server triggers Lambda functions through its AWS SNS/SQS compatible event notification service. Supported targets are message queues such as Kafka, NATS, AMQP, MQTT, Webhooks, and databases such as Elasticsearch, Redis, Postgres, and MySQL. Thumbnail generation, OCR and audit compliance are good examples of lambda computing.
Encryption and Tamper-Proof
Minio provides confidentiality, integrity and authenticity assurances for encrypted data with negligible performance overhead. Both server side and client side encryption are supported using AES-256-GCM, ChaCha20-Poly1305, and AES-CBC. Encrypted objects are tamper-proofed with AEAD server-side encryption.
Pluggable Storage Backend
In addition to Minio’s own filesystem and erasure code backends for DAS and JBODs, external storage backends such as NAS, Google Cloud Storage, and Azure Blob Storage are supported as well.
