Package de.iip_ecosphere.platform.deviceMgt.minio

Class S3Storage

  • All Implemented Interfaces:
    de.iip_ecosphere.platform.deviceMgt.storage.Storage
    Direct Known Subclasses:
    S3PackageStorage
    public class S3Storage
extends java.lang.Object
implements de.iip_ecosphere.platform.deviceMgt.storage.Storage
    A S3Storage grants access to the storage through s3. For this purpose it uses MinioClient to communicate with the s3 storage. The storage can be set to a fixed prefix, so it is only working with a subset of the bucket.
