Warning

We strongly recommend using virtualenv for isolating python packages. Configuration tutorial is available here: How to install Python virtualenv or virtualenvwrapper on EO-Lab.

If virtualenv is activated:

(myvenv) eouser@vm01:~$ pip3 install boto3

Or if we install package globally:

eouser@vm01:~$ sudo pip3 install boto3

Script for downloading one .png file

Remember to generate EC2 credentials for your project, as described here: How to generate and manage EC2 credentials on EO-Lab.

Remember that you cannot change the output file extension. If you do so, the file content would be empty.

import boto3

access_key='YOUR ACCESS KEY'
secret_key='YOUR SECRET KEY'
key='Landsat-5/TM/L1T/2011/11/16/LS05_RMPS_TM__GTC_1P_20111116T100042_20111116T100111_147386_0194_0035_4BF1/LS05_RMPS_TM__GTC_1P_20111116T100042_20111116T100111_147386_0194_0035_4BF1.BP.PNG'
host='http://eodata.cloudferro.com'

s3=boto3.resource('s3',aws_access_key_id=access_key,
aws_secret_access_key=secret_key, endpoint_url=host,)

bucket=s3.Bucket('DIAS')

bucket.download_file(key, '/home/eouser/image.png')

Save your file with .py extension and run with the ‘python3 <filename.py>’ command in your terminal. For example:

(boto3) eouser@vm01:~$ python3 eodownload.py

And here’s result:

(boto3) eouser@vm01:~$ python3 eodownload.py

(boto3) eouser@vm01:~$ ls
