Deploy Minio

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

To run it, follow these steps:

Install the kraft CLI tool and a container runtime engine, e.g. Docker.
Clone the examples repository and cd into the examples/minio/ directory:

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. We use fra0 (Frankfurt, 🇩🇪) in this guide:

# Set Unikraft Cloud access token
export UKC_TOKEN=token
# Set metro to Frankfurt, DE
export UKC_METRO=fra0

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

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

The output shows the instance URL and other details:

[●] Deployed successfully!
 │
 ├────────── name: minio-w2my8
 ├────────── uuid: 31e691ad-05a0-48b6-ad49-7f79da8e1754

 ├─────────── url: https://icy-bird-tregaga9.fra0.kraft.host

 ├──── private ip: 172.16.6.4
 └────────── args: /usr/bin/minio server --address 0.0.0.0:9000 --console-address 0.0.0.0:9001 /data

In this case, the instance name is minio-w2my8 and the URL is https://icy-bird-tregaga9.fra0.kraft.host. They are different for each run.

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

At any point in time, you can list information about the instance:

kraft cloud instance list

When done, you can remove the instance:

kraft cloud instance remove minio-w2my8

Customize your Application

To customize the application, update the files in the repository, listed below:

Kraftfile: the Unikraft Cloud specification, including command-line arguments
Dockerfile: In case you need to add files to your instance’s rootfs
