Integrate with MinIO

This guide describes object storage access in Charmed Kubeflow (CKF) through MinIO.

Set keys

First, check if the access key is configured:

juju config minio access-key

Then, check if the secret key is configured:

juju config minio secret-key

In case they are not set, create a new username and password:

juju config minio access-key=<username>
juju config minio secret-key=<password>

Configure access

MinIO needs to be added to the pod and configured to be accessible. To do so, you have to create a YAML file. For example,

touch allow-minio.yaml

After that, open the file and update it as follows:

apiVersion: kubeflow.org/v1alpha1
kind: PodDefault
metadata:
 name: access-minio
spec:
 desc: Allow access to Minio
 selector:
   matchLabels:
     access-minio: "true"
 env:
   - name: AWS_ACCESS_KEY_ID
     valueFrom:
       secretKeyRef:
         name: mlpipeline-minio-artifact
         key: accesskey
         optional: false
   - name: AWS_SECRET_ACCESS_KEY
     valueFrom:
       secretKeyRef:
         name: mlpipeline-minio-artifact
         key: secretkey
         optional: false
   - name: MINIO_ENDPOINT_URL
     value: http://minio.kubeflow.svc.cluster.local:9000

Once updated, run in a terminal the following command:

kubectl apply -f allow-minio.yaml -n <user-namespace>

Refresh Juju

Refresh Juju to update previous changes:

juju refresh –kubeflow

Now you should be able to access MinIO.

You can check if it is added to the model as follows:

sudo microk8s kubectl get PodDefault -n admin

You should see allow-minio.

Another option is to access the MinIO dashboard. You can do so by running juju status and accessing the provided MinIO IP address. To login, use the credentials you previously set up.
