What is Minio?

Minio is an open source distributed object storage server written in Go, designed for Private Cloud infrastructure providing S3 storage functionality. Minio is the best server which is suited for storing unstructured data such as photos, videos, log files, backups, and container. Size of an object can be range from a KBs to a maximum of 5TB. Minio server is light enough with application stacks like Redis, MySql, and Gitlab.

How Minio Works?

MinIO's high-performance object storage suite is software defined and enables customers to build cloud-native data infrastructure for machine learning, analytics and application data workloads.

MinIO uses a key-management-system (KMS) to support SSE-S3. If a client requests SSE-S3, or auto-encryption is enabled, the MinIO server encrypts each object with a unique object key which is protected by a master key managed by the KMS. Given the exceptionally low overhead, auto-encryption can be turned on for every application and instance. MinIO is a natural fit for enterprises looking for a consistent, performant and scalable object store for their hybrid cloud strategies. Kubernetes-native by design, S3 compatible from inception, MinIO has more than 7.7M instances running in AWS, Azure and GCP today.

Minio supports multiple pluggable storage backend including local disk, Kubernetes PVC, NAS and object storage provided by Public Cloud like Azure and GCP. Minio supports eraser coding which replicates & divides the data and spread it across multiple drives providing high availability and reliability.

It has a single standalone deployment with a single disk or multiple disks, distributed cluster where Minio runs on various hosts. Disks can be EBS, Google Disk, Ceph RBD, ISCSI disk, direct attached hard disk, or it can be a folder and folder backed by NFS. Minio uses erasure coding which divides data into smaller objects and spread across multiple disks protecting from disk failure, redundancy, and scalability.

Minio can also leverage existing object storage solutions like Azure blob storage and object storage on Google Cloud Platform. It acts as an S3 object layer transparently on top of existing object storage providing a single interface for accessing multiple Cloud storage.

Also, leverage Minio on existing Docker and Kubernetes environment providing object storage to Microservices. Minio can consume the disks in the form of PVC and store data on them.

How to Adopt Minio?

Pre-requisites for Implementing Minio

Minio

Minion Images

  • One Ubuntu 16.04 server set up by following initial server setup.
  • A fully registered domain name.
  • Following DNS records set up MINIO server. Follow this hostname for details on how to add them.
  • A record with your server name (minio_server.com) pointing to your object server’s IPv4 address.
  • Install Go on Ubuntu 16.04.
  • Installing and Configuring MINIO server.
  • Installing the Systemd Startup Script.
  • Starting a MINIO Server.
  • Securing Access to MINIO Server With an SSL/TLS Certificate.
  • Securely connecting to MINIO with web Interface using HTTPS.

Why Minio Matters?

Minio in distributed mode to set up a highly – available storage system with a single object storage deployment. With distributed Minio, optimally use storage devices, irrespective of location in a network.

Data Protection

In this, Distributed Minio protects multiple nodes and drives failures and bit rot using erasure code. The minimum disks required for this distributed Minio is 4, this erasure code is automatically hit as distributed Minio launched.

High Availability

A stand-alone Minio server goes down if the server hosting the disk goes offline.There is also Distributed Minio setup with n number of the disk with safe data as long as more disks are online. Therefore, need minimum of disks to create new objects.

Limits

In Minio there are the stand-alone mode, the distributed mode has per usage required minimum limit 2 and maximum 32 servers. But there is no limit of disks shared across the Minio server. If we need multiple setups, quickly spin up multiple Minio Instances managed by tool like Kubernetes.

Best Practices of Minio

Distributed Minio is a Private Cloud deployed via Docker Compose and Swarm mode. The main difference between these two being, Docker Compose creates a single host, multi-container deployment, while Swarm mode creates a multi-host, multi-container deployment.

This means Docker compose get started with Distributed Minio on computer-ideal for deployment, testing staging environment. While deploying Distributed Minio on Swarm offers a more robust, production level deployment.

  • Minio Custom Access and Secret Keys.
  • Minio Custom Access and Secret Keys using Docker secrets.
  • Create a Minio service using Docker service to read from Docker secrets.
  • Minio Custom Access and Secret Key files.
  • Retrieving Container ID.
  • Starting and Stopping Containers.
  • Minio container logs.
  • Monitor Minio Docker Container.

Concluding Minio

Minio is the best Private Cloud Storage. It is a high performance distributed object storage server, designed for large-scale Private Cloud infrastructure. Minio widely deployed across the world with over 164.1M + Docker pulls. Minio is distributed object storage server written in Go and Open source under Apache version 2.0.

Prerequisites

Docker installed on your machine. Download the relevant installer from here.

Run Standalone MinIO on Docker.

MinIO needs a persistent volume to store configuration and application data. However, for testing purposes, you can launch MinIO by simply passing a directory (/data in the example below). This directory gets created in the container filesystem at the time of container start. But all the data is lost after container exits.

To create a MinIO container with persistent storage, you need to map local persistent directories from the host OS to virtual config ~/.minio and export /data directories. To do this, run the below commands

GNU/Linux and macOS

Windows

Run Distributed MinIO on Docker

Distributed MinIO can be deployed via Docker Compose or Swarm mode. The major difference between these two being, Docker Compose creates a single host, multi-container deployment, while Swarm mode creates a multi-host, multi-container deployment.

This means Docker Compose lets you quickly get started with Distributed MinIO on your computer - ideal for development, testing, staging environments. While deploying Distributed MinIO on Swarm offers a more robust, production level deployment.

MinIO Docker Tips

Minio

MinIO Custom Access and Secret Keys

To override MinIO's auto-generated keys, you may pass secret and access keys explicitly as environment variables. MinIO server also allows regular strings as access and secret keys.

GNU/Linux and macOS

Windows

Run MinIO Docker as a regular user

Docker provides standardized mechanisms to run docker containers as non-root users.

GNU/Linux and macOS

On Linux and macOS you can use --user to run the container as regular user.

NOTE: make sure --user has write permission to ${HOME}/data prior to using --user.

Windows

On windows you would need to use Docker integrated windows authentication and Create a container with Active Directory Support

NOTE: make sure your AD/Windows user has write permissions to D:data prior to using credentialspec=.

MinIO Custom Access and Secret Keys using Docker secrets

To override MinIO's auto-generated keys, you may pass secret and access keys explicitly by creating access and secret keys as Docker secrets. MinIO server also allows regular strings as access and secret keys.

Create a MinIO service using docker service to read from Docker secrets.

MinIO Custom Access and Secret Key files

To use other secret names follow the instructions above and replace access_key and secret_key with your custom names (e.g. my_secret_key,my_custom_key). Run your service with

MINIO_ROOT_USER_FILE and MINIO_ROOT_PASSWORD_FILE also support custom absolute paths, in case Docker secrets are mounted to custom locations or other tools are used to mount secrets into the container. For example, HashiCorp Vault injects secrets to /vault/secrets. With the custom names above, set the environment variables to

Retrieving Container ID

To use Docker commands on a specific container, you need to know the Container ID for that container. To get the Container ID, run

-a flag makes sure you get all the containers (Created, Running, Exited). Then identify the Container ID from the output.

Starting and Stopping Containers

To start a stopped container, you can use the docker start command.

Minions The Rise Of Gru

To stop a running container, you can use the docker stop command.
