ceph/examples/rgw/golang/put-bucket-notification-creation

Introduction

This directory contains Golang code examples on how to create a put bucket notification to a topic and S3 bucket running on a Ceph RGW cluster.

Prerequisite

Linux machine running an RGW Ceph cluster. Preferrably started with the OSD=1 MON=1 MDS=0 MGR=0 RGW=1 ../src/vstart.sh --debug --new command. Go installed on the Linux machine.

Workflow Procedure

1. Install AWS CLI version one on your Linux machine as explained here
2. Create a topic on the Ceph cluster with the command

aws --region default --endpoint-url http://localhost:8000 sns create-topic --name=sample-topic --attributes='{"push-endpoint": "http://localhost:10900"}'

3. Create a bucket to which the topic will be attached to with the command

aws --endpoint-url http://localhost:8000 s3 mb s3://sample-bucket

4. Navigate through your file system to where the Golang example code exists on your terminal.
5. Install the required Golang packages on the system.

go mod init examples/put-bucket-notification-creation/v2
go get github.com/aws/aws-sdk-go
go mod tidy

6. Run the Golang program as go run put-bucket-notification-creation.go -b sample-bucket -t arn:aws:sns:default::sample-topic on the terminal window to create the put bucket notification with the suffix filter rule.
7. Upload any jpg file you have to the bucket with the command

aws --endpoint-url http://localhost:8000 s3 cp your-jpg-file.jpg s3://sample-bucket
