Introduction

We show how to deploy a Kubernetes cluster and set a MinIO Operator with Helm 3.

MinIO is a high-performance, S3 compatible object store. It is built for large scale AI/ML, data lake and database workloads. Helm is a package manager for Kubernetes that allows developers and operators to more easily package, configure, and deploy applications and services onto Kubernetes clusters.

Prerequisites

• TFChain account with TFT
• Deploy Kubernetes cluster with one master and one worker (IPv4)
• Make sure you can connect via SSH on the terminal

Create an SSH Tunnel

To access the MinIO Operator, we need to create an SSH tunnel with the port 9090.

• Open a terminal and create an SSH tunnel

  ssh -4 -L 9090:127.0.0.1:9090 root@<VM_IP>
  

Simply leave this window open and follow the next steps.

Set the VM

We set the Master VM to access the minIO Operator.

• Install the prerequisites:

  apt update
  apt install git -y
  apt install wget
  apt install jq -y
  

• Install Helm

  wget https://get.helm.sh/helm-v3.14.3-linux-amd64.tar.gz
  tar -xvf helm-v3.14.3-linux-amd64.tar.gz
  mv linux-amd64/helm /usr/local/bin/helm
  

• Install yq

  wget https://github.com/mikefarah/yq/releases/download/v4.43.1/yq_linux_amd64.tar.gz
  tar -xvf yq_linux_amd64.tar.gz
  mv yq_linux_amd64 /usr/bin/yq
  

Set MinIO

We can then set the MinIO Operator. For this step, we mainly follow the MinIO documentation here.

• Add the MinIO repo

  helm repo add minio-operator https://operator.min.io
  

• Validate the MinIO repo content

  helm search repo minio-operator
  

• Install the operator

  helm install \
  --namespace minio-operator \
  --create-namespace \
  operator minio-operator/operator
  

• Verify the operator installation

  kubectl get all -n minio-operator
  

Access the MinIO Operator

You can then access the MinIO Operator on your local browser (port 9090)

localhost:9090

To log in the MinIO Operator, you will need to enter the token. To see the token, run the following line:

kubectl get secret/console-sa-secret -n minio-operator -o json | jq -r ".data.token" | base64 -d

Enter the token on the login page:

You then have access to the MinIO Operator:
