What this API does
MinIO S3 API offers a fully S3-compatible, open-source object storage system designed for self-hosted environments. It enables developers to build scalable and secure cloud storage solutions on Docker, Kubernetes, or bare metal infrastructure. Key features include bucket versioning, encryption, metadata tagging, and high-performance object streaming, which help streamline data storage, retrieval, and management operations.
How it works
The API uses standard HTTP methods and supports popular S3 SDKs such as boto3, making integration familiar and straightforward for developers. MinIO allows for actions like storing, retrieving, and managing objects using standard S3 commands.
Authentication
MinIO requires authentication using access and secret keys. Developers must configure these keys for secure access to the API endpoints. This ensures that only authorized applications can perform storage operations.
Example usage
PUT /mybucket/myobject- Uploads an object.GET /mybucket/myobject- Retrieves an object from the bucket.DELETE /mybucket/myobject- Deletes an object from the bucket.HEAD /mybucket/myobject- Retrieves metadata for an object.
Limits
Documentation does not specify rate limits, but operational limits may vary based on the deployment environment and underlying infrastructure.
Ideal use cases
- Building applications requiring scalable cloud storage solutions.
- Creating private data management systems without vendor lock-in.
- Deploying microservices that utilize object storage.
- Integrating storage solutions within CI/CD pipelines for artifact management.
