Minio

Copy page

This guide shows you how to use MinIO, a High Performance Object Storage which is Open Source, Amazon S3 compatible, Kubernetes Native and works for cloud native workloads like AI.

To run it, follow these steps:

1. Install the kraft CLI tool and a container runtime engine, for example Docker.

2. Clone the examples repository and cd into the examples/minio/ directory:

Code
 
git clone https://github.com/kraftcloud/examples
cd examples/minio/

Make sure to log into Unikraft Cloud by setting your token and a metro close to you. This guide uses fra (Frankfurt, 🇩🇪):

Code
 
# Set Unikraft Cloud access token
export UKC_TOKEN=token
# Set metro to Frankfurt, DE
export UKC_METRO=fra

When done, invoke the following command to deploy this app on Unikraft Cloud:

Code
 
kraft cloud deploy -p 443:9001/http+tls -p 9000:9000/tls -M 512 .

The output shows the instance address and other details:

Code
 
[●] Deployed successfully!

In this case, the instance name is minio-w2my8 and the address is https://icy-bird-tregaga9.fra.unikraft.app. They're different for each run.

To test, point your browser at the address. The default account/password are minioadmin/minioadmin.

You can list information about the instance by running:

Code
 
kraft cloud instance list

Code

When done, you can remove the instance:

Code
 
kraft cloud instance remove minio-w2my8
