Upload and delete an object

Contents:

To upload your data (documents, photos, videos, etc.), it is first necessary to create a bucket. A file can only be saved in a bucket.

S3cmd

Upload an object

To upload a file, use the following command:

s3cmd put NameOfTheFile s3://NameOfTheBucket/NameOfTheFile

The output of the command will be similar to this:

$ s3cmd put innovo.txt s3://innovo-test/innovo.txt
upload: 'innovo.txt' -> 's3://innovo-test/innovo.txt'  [1 of 1]
 95 of 95   100% in    0s   176.63 B/s  done

Delete an object

To delete a file, use the following command:

s3cmd del s3://NameOfTheBucket/NameOfTheFile

The output of the command will be similar to this:

$ s3cmd del s3://innovo-test/innovo.txt
delete: 's3://innovo-test/innovo.txt'

S3Browser

Upload an object

After opening S3Browser, we click on the desired “Bucket”(1), then select “Upload”(2) and finally “Upload file(s)”(3).

Here we select the file(1) and click on Open(2).

Delete an object

To delete a file, select it with a left mouse click(1). Then click on “Delete”(2).

Finally, confirm the action with “Yes”.

Cyberduck

Upload an object

After opening Cyberduck, click on the bucket(1), then click on Action(2) and then on Upload(3).

Here we choose our file and click on Upload.

Delete an object

To delete a file, select it with a left mouse click(1). It is then deleted via “Action”(2) and “Delete”(3).

This action is then confirmed by clicking on “Delete” again.

Boto3

In Boto3, we first need the S3 credentials so that a script can be used. For details, see: Create and use S3 credentials #Boto3.

Upload an object

To upload a file, we have to use a client and specify the bucket to which the file should be uploaded. One option could look like this:

## Create the S3 client
s3 = boto3.client('s3')

## Upload an object
s3.upload_file(Bucket='iNNOVO-Test', Key='innovo.txt')

A complete script for Boto3 including authentication may be similar to this:

#!/usr/bin/env/python

## Define that boto3 should be used
import boto3
from botocore.client import Config

## Authentication
s3 = boto3.resource('s3',
                        endpoint_url='https://s3.openstack.de-west-01.wiit-cloud.io',
                        aws_access_key_id='aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa',
                        aws_secret_access_key='bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb',
                    )

## Create the S3 client
s3 = boto3.client('s3')

## Upload an object
s3.upload_file(Bucket='iNNOVO-Test', Key='innovo.txt')

Delete an object

Just as for uploading a file, the client is also required to delete a file. For this, we specify the bucket in which the file is stored, in addition to the file itself. One option could look like this:

## Create the S3 client
s3 = boto3.client('s3')

## Delete an object
s3.delete_object(Bucket='iNNOVO-Test', Key='innovo.txt')

A complete script for Boto3 including authentication may look like this:

#!/usr/bin/env/python

## Define that boto3 should be used
import boto3
from botocore.client import Config

## Authentication
s3 = boto3.resource('s3',
                        endpoint_url='https://s3.openstack.de-west-01.wiit-cloud.io',
                        aws_access_key_id='aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa',
                        aws_secret_access_key='bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb',
                    )

## Create the S3 client
s3 = boto3.client('s3')

## Delete an object
s3.delete_object(Bucket='iNNOVO-Test', Key='innovo.txt')
