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](https://docs.aws.amazon.com/cli/v1/userguide/install-linux.html) +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. Run ``` go mod tidy ``` to install the required Go packages on the system. +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 +``` diff --git
