Minio

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 unikraft CLI. You need a BuildKit builder. The easiest way to get one is via Docker. Alternatively, you can also directly set up and use BuildKit, see the quick start.

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

   Code
   git clone https://github.com/unikraft-cloud/examples
   cd examples/minio/

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

Code
unikraft login

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

Code
unikraft build . --output <my-org>/minio:latest
unikraft run --metro fra \
  -m 512M \
  -p 443:9001/tls+http \
  -p 9000:9000/tls \
  --scale-to-zero policy=on,cooldown-time=1000 \
  --image <my-org>/minio:latest

The output shows the instance address and other details:

Code
metro:        fra
name:         minio-w2my8
uuid:         31e691ad-05a0-48b6-ad49-7f79da8e1754
state:        starting
image:        <my-org>/minio
resources:
  memory:     512MiB
  vcpus:      1
service:
  uuid:       8fdad5ff-9276-5f35-f94e-3d9d9b244a15
  name:       icy-bird-tregaga9
  domains:
  - fqdn:     icy-bird-tregaga9.fra.unikraft.app
networks:
- uuid:       f3a7d1f6-b1ca-68d0-6b45-7e9179ad0966
  private-ip: 10.0.6.4
  mac:        12:b0:44:5e:b0:54
timestamps:
  created:    just now

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
unikraft instances list

Code
METRO  NAME         STATE    IMAGE           ARGS  MEMORY  VCPUS  FQDN                                CREATED
fra    minio-w2my8  running  <my-org>/minio        512MiB  1      icy-bird-tregaga9.fra.unikraft.app  2 minutes ago

When done, you can remove the instance:

Code
unikraft instances delete minio-w2my8

Customize your app

To customize the app, 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
