Instructions for installing MinIO with Docker

Introduction

MinIO is a high-performance, open-source Object Storage system that is fully compatible with the Amazon S3 API. Key advantages include ultra-fast data processing speeds, a lightweight cloud-native architecture, easy scalability, and high security with advanced data encryption capabilities.

Detail

First, create a docker-compose.yml file with the following content, changing the YOUR_ACCESS_KEY and YOUR_SECRET_KEY values to suit your needs:

services:
minio:
image: quay.io/minio/minio:latest
container_name: minio-dev
ports:
- "9000:9000"
- "9001:9001"
environment:
MINIO_ROOT_USER: YOUR_ACCESS_KEY
MINIO_ROOT_PASSWORD: YOUR_SECRET_KEY
volumes:
- minio_data:/data
command: server /data --console-address ":9001"

volumes:
minio_data:


Run the docker container as follows:

docker-compose up -d


If you want to use an interface for easier management, you need to install the MinIO Client (mc) as follows:

brew install minio/stable/mc

mc --version
mc version RELEASE.2025-08-13T08-35-41Z (commit-id=7394ce0dd2a80935aded936b09fa12cbb3cb8096)
Runtime: go1.24.6 darwin/arm64
Copyright (c) 2015-2025 MinIO, Inc.
License GNU AGPLv3 <https://www.gnu.org/licenses/agpl-3.0.html>

mc alias set myminio http://localhost:9000 YOUR_ACCESS_KEY YOUR_SECRET_KEY

  • The brew command above is for MacOS; please change it accordingly for the OS you are using.
  • After installation, check the version used and create an alias to connect to the running MinIO Docker container.


Here are some commands to use MinIO:

mc mb myminio/test
mc cp test myminio/test
mc ls myminio/test
mc cp myminio/test/test.txt ./downloaded_test.txt

  • mc mb myminio/test: Create a new bucket named test on the myminio alias.
  • mc cp test myminio/test: Copy the test file or directory to the test bucket of myminio.
  • mc ls myminio/test: List the files and directories inside the test bucket.
  • mc cp myminio/test/test.txt ./downloaded_test.txt: Download the test.txt file from the bucket to the local machine with a new name.


Then you can view the UI on the browser as follows:


Happy coding!

Introduction This is a comprehensive page about the technologies I have shared in series format. You can view brief introductions and links to directly access each series you are interested in. In the field of software development, to deploy a product from the initial idea to its release, the standard process typically involves several stages as follows: Database : Designing and implementing the database according to business requirements, storing data during the system's operation. Backend : Handling the main logic of the system, communicating with the database and services. Frontend : Building the interface for users to interact with the system, which could be a desktop, mobile, or web application. This usually includes implementing UI/UX and integrating APIs from the backend. DevOps : Deploying the system for use, which can be done on a server or in the cloud. Testing : Applying testing methods to ensure the product meets the standards for release. Of course, these are just stan...

Kubernetes Deployment for Zero Downtime

Image
Introduction In Kubernetes (K8s) , a Pod is the smallest resource unit used to run one or more containers during deployment. There are several ways to create a Pod : you can create it directly, use a ReplicationController , or a ReplicaSet . However, the most commonly used resource for managing Pods is the Deployment . When you use a Deployment , it actually creates a ReplicaSet to manage the Pods but comes with many additional benefits that support the deployment process. Some Advantages of Deployment : Ensures Pod Availability : It guarantees that the specified number of Pods are always running according to the configuration, automatically deploying additional Pods if any failures occur. Supports Restart and Undo Deployment : Allows you to easily restart or roll back to previous versions of your Deployment . Zero Downtime Deployment : When updating configurations or scaling Deployments , zero downtime is crucial. This means that new Pods are created while the old Pods are stil...

Deploying a NodeJS Server on Google Kubernetes Engine

Image
Introduction to GKE Google Kubernetes Engine (GKE) is a managed Kubernetes service provided by Google Cloud Platform , facilitating simple and efficient deployment of Docker images. We only need to provide some configuration for the number of nodes, machine types, and replicas to use. Some Concepts Cluster A Cluster is a collection of Nodes where Kubernetes can deploy applications. A cluster includes at least one Master Node and multiple Worker Nodes . The Master Node is used to manage the Worker Nodes . Node A Node is a server in the Kubernetes Cluster. Nodes can be physical servers or virtual machines. Each Node runs  Kubernetes , which is responsible for communication between the Master Node and Worker Node , as well as managing Pods and containers running on it. Pod A Pod is the smallest deployable unit in Kubernetes . Each Pod contains one or more containers, typically Docker containers. Containers in the same Pod share a network namespace, meaning they have the ...

Setting up Kubernetes Dashboard with Kind

Image
Introduction In a previous article, I guided you through using Helm to deploy on Google Kubernetes Engine . However, if you want to cut down costs by using Kubernetes in your local environment instead of relying on a cloud provider during development, then Kind is your go-to. There are several tools to help set up Kubernetes locally, such as MiniKube , Kind , K3S , KubeAdm , and more. Each tool has its own pros and cons. In this article, I'll walk you through using Kind to quickly set up a Kubernetes cluster on Docker . Kind stands out for its compactness, making Kubernetes start up quickly, being user-friendly, and supporting the latest Kubernetes versions. Working with Kind Firstly, follow the instructions here to install Kind according to your operating system. If you're using Ubuntu , execute the command: [ $( uname -m ) = x86_64 ] && curl -Lo ./kind https://kind.sigs.k8s.io/dl/v0.23.0/kind-linux-amd64 chmod +x ./kind sudo mv ./kind /usr/local/bin/ki...

Monitoring with cAdvisor, Prometheus and Grafana on Docker

Image
Introduction Monitoring a system is crucial after deploying a product to a production environment. Keeping an eye on system metrics like logs , CPU , RAM , disks , etc, helps identify the system's status, performance issues, and provides timely solutions to ensure stable operations. While cloud providers like Google , Amazon , or Azure offer built-in monitoring systems, if your company needs to manage multiple applications/systems/containers and desires a centralized monitoring system for easier management, using cAdvisor , Prometheus , and Grafana is a sensible choice. These three popular open-source tools are widely used by DevOps teams, especially for monitoring container applications. cAdvisor Developed by Google , cAdvisor is an open-source project used to analyze resource usage, performance, and other metrics from container applications, providing an overview of all running containers. Find more details here Prometheus Prometheus is a toolkit for system monitoring and a...

Introduction NodeJS is an open-source and cross-platform JavaScript runtime environment . Here are some key points about NodeJS : V8 Engine : NodeJS runs on the V8 JavaScript engine , which is also the core of Google Chrome . This allows NodeJS to be highly performant. Asynchronous and Non-Blocking : NodeJS  uses an event-driven, non-blocking I/O model. It’s lightweight and efficient, making it ideal for data-intensive real-time applications. Single-Threaded : NodeJS  runs in a single process, handling multiple requests without creating new threads. It eliminates waiting and continues with the next request. Common Language : Frontend developers who write JavaScript for browsers can use the same language for server-side code in NodeJS . You can even use the latest ECMAScript standards without waiting for browser updates. This page is designed to compile articles related to NodeJS , including how to integrate it with various libraries and relevant tech stacks. I will cont...
