MinIO is a high-performance, software-defined object storage suite that enables customers to build cloud-native data infrastructure for machine learning, analytics and application data workloads.
The MinIO client can be used to manage S3 buckets and objects. You can download the MinIO client script with wget https://dl.minio.io/client/mc/release/linux-amd64/mc.
The script must be made executable (chmod +x mc) and then you can configure the client with your S3 (Openstack EC2) credentials and the Cloud@CNAF API endpoint:
[ffornari@tb-cloud-ui ~]$ ./mc --debug config host add minio https://tb-cloud-api-pub.cr.cnaf.infn.it:8080 <aws_key> <aws_secret> --api S3v2
Added `minio` successfully.
[ffornari@tb-cloud-ui ~]$
Finally, you can manage your buckets and objects:
(NG-ffornari-tier1) [ffornari@tb-cloud-ui test_clients]# ./mc ls minio
