Minio NATS Demo

Use Minio to notify of changes through NATS and sync changes between two clouds (or a laptop and a cloud).

Overview

Minio makes it easy to manage an object store with an S3 interface across multiple different platforms, from your local desktop to other clouds beyond AWS.

This demonstration will show you how to run a Minio object store on a local laptop, configure a local NATS message bus and finally replicate objects to other clouds.

Tutorial

1. Install and run gnatsd

   go get github.com/nats-io/gnatsd; gnatsd -D -V

2. Install minio

   go get github.com/minio/minio

3. Configure minio for local NATS event subscription

   edit ~/.minio/config.json

   set "nats"."1"."enable": true

   ...
   "nats": {
       "1": {
           "enable": true,
           "address": "0.0.0.0:4222",
           "subject": "bucketevents",
   ...

4. Run minio

   Set ~/minio-tmp/ to any directory you want to store your objects in.

   minio server ~/minio-tmp/

5. Run minioNATS

   go run minionats/main.go -remote s3://accessKeyId:accessSecretKey@host:port -local s3://accessKeyId:accessSecretKey@host:port

6. Open Browsers to your test bucket Minio Browser and an S3 Browser

7. Upload a File to your Minio Browser. Watch it automatically get added to your S3 browser

8. Delete a File from your Minio Browser. Watch it automatically get removed from your S3 Browser
