Are you looking for object storage software to host on your server?
I guess, yes?
There is plenty of cloud-based object storage like AWS S3 and other I mentioned here. However, if you need to host your data on your server, MinIO can help within your data centers.
MiniIO is open-source, popular distributed object storage software and compatible with S3. It’s enterprise-ready and known for its high performance.
You can use MinIO from a simple web application to large data distribution workloads for analytics and machine learning applications. It can help in many use cases.
- Standard flat file storage
- Multi-cloud data distribution
- Disaster recovery
- Data analytics
Is it bulky software?
Nope, it’s just around ~50MB and Kubernetes-friendly. It writes data and metadata as an object. This removes the dependency on having an additional database or software to store metadata and improve performance.
The below architecture from their official site.
Let’s explore some of the features worth noting.
- High-performance – the title says. It’s capable of reading/writing at the speed of ~170GB/s. That’s a lot!
- Scalable – go for clustering and scale as you need
- Data protection using Erasure code method
- Multiple encryption supported including AES-CBC, AES-256-GCM, ChaCha20
- Compatible with common KMS
- Application and user identity
- Event notification
- Federation using etcd and CoreDNS
MinIO is a good choice for software defined storage. Let’s explore how to set things up.
Installing MinIO Server
For this demonstration, I will install on CentOS which is hosted on Kamatera.
- Login to the server
- Create a folder under desired file system. Maybe
- Navigate to the newly created folder and run the below wget command
It will download a binary file and should looks like this.
-rw-r--r-- 1 root root 48271360 Oct 18 21:57 minio
Make the file executable with
chmod 755 minio
Let’s start the MinIO as a server.
./minio server /data &
/data mentioned above is the file system where MinIO will store the objects.
Starting is quick and you should see the startup info as below.
Let’s access MinIO on browser with default credentials – minioadmin:minioadmin
Interface is very neat and clean but before anything, let’s change the default credential as it expose the risk. There is no option to change the admin credential through browser but environment variables.
To change MinIO default credential, we will export export the access and secret key as below and start the MinIO.
export MINIO_ACCESS_KEY=geekflare export MINIO_SECRET_KEY=geekpassword ./minio server /data &
Now, it shouldn’t complain about default credential detection warning.
Let’s try to upload some files.
- Click + icon at the right bottom and create a bucket
- I uploaded a test file and immediately visible on browser
and, on the server
[[email protected] geekflare]# ls -ltr total 4 -rw-r--r-- 1 root root 11 Oct 19 11:09 MinIO-Test.txt [[email protected] geekflare]#
If you click on file share button on the browser, you will get the shareable link and an option to set the expiry.
MinIO client is more than aws-cli which let you manage the storage. Client is available for Windows, macOS and Linux.
To install on Linux, run the following.
wget https://dl.min.io/client/mc/release/linux-amd64/mc chmod 755 mc
mc command to see the command help.
[[email protected] ~]# ./mc NAME: mc - MinIO Client for cloud storage and filesystems. USAGE: mc [FLAGS] COMMAND [COMMAND FLAGS | -h] [ARGUMENTS...] COMMANDS: alias set, remove and list aliases in configuration file ls list buckets and objects mb make a bucket rb remove a bucket cp copy objects mirror synchronize object(s) to a remote site cat display object contents head display first 'n' lines of an object pipe stream STDIN to an object share generate URL for temporary access to an object find search for objects sql run sql queries on objects stat show object metadata mv move objects tree list buckets and objects in a tree format du summarize disk usage recursively retention set retention for object(s) legalhold manage legal hold for object(s) diff list differences in object name, size, and date between two buckets rm remove objects version manage bucket versioning ilm manage bucket lifecycle encrypt manage bucket encryption config event manage object notifications watch listen for object notification events undo undo PUT/DELETE operations policy manage anonymous access to buckets and objects tag manage tags for bucket and object(s) replicate configure server side bucket replication admin manage MinIO servers update update mc to latest release GLOBAL FLAGS: --autocompletion install auto-completion for your shell --config-dir value, -C value path to configuration folder (default: "/root/.mc") --quiet, -q disable progress bar display --no-color disable color theme --json enable JSON lines formatted output --debug enable debug output --insecure disable SSL certificate verification --help, -h show help --version, -v print the version TIP: Use 'mc --autocompletion' to enable shell autocompletion VERSION: RELEASE.2020-10-03T02-54-56Z [[email protected] ~]#
Let’s try to list the file which I uploaded through
First, we need to set the alias to the storage we want to administer.
[[email protected] ~]# ./mc alias set minio http://xx.71.141.xx:9000/ geekflare geekpassword Added `minio` successfully. [[email protected] ~]#
- minio is the alias name. You can change this to whatever you want.
- Change HTTP endpoint to your real one
- Change access and secret key with yours
and, to list, will use ls command as below.
[[email protected] ~]# ./mc ls --recursive minio [2020-10-19 11:09:06 UTC] 11B geekflare/MinIO-Test.txt [[email protected] ~]#
Great. it works!
You can do literaly every thing through the client. Not just you can mange MinIO cloud storage but also GCS, AWS S3, Azure.
Check out this client quick start guide for more details.
Depending on your application stack, you can interact with object storage programmatically using SDK. It supports Go, Python, Node.js, .NET, Haskell and Java.
Add MiniIO gateway to S3, Azure, NAS, HDFS to take advantage of MinIO browser and disk caching.
If you are looking for private, hybrid or multi-cloud object storage then MinIO looks promising. Give a try and you’ll fall in love with it. To test things, you can get Kamatera’s MinIO VM or install yourself on any Cloud server.
