To use boto3 your virtual machine has to be initialized in project with
eo data.
We strongly recommend using virtualenv for isolating python packages. Configuration tutorial is presented below:
https://creodias.eu/faq/-/asset_publisher/hv0ovzc1bXXS/content/how-to-install-python-virtualenv-virtualenvwrapper-?redirect=%2Ffaq&inheritRedirect=true If virtualenv is activated:
Or if we install package globally:
1 | $ sudo pip install boto3 |
Two examples for listing products:
Client:
- low-level service access
- generated from service description
- exposes botocore client to the developer
- typically maps 1:1 with the service API
- snake-cased method names (e.g. ListBuckets API => list_buckets method)

access_key='anystring' secret_key='anystring'
host='http://data.cloudferro.com'
s3=boto3.client('s3',aws_access_key_id=access_key, aws_secret_access_key=secret_key, endpoint_url=host,)
for i in s3.list_objects(Delimiter='/', Bucket="DIAS", Prefix='Sentinel-2/MSI/L1C/2018/07/01/',MaxKeys=30000)['CommonPrefixes']: print(i) |
|
Resource:
- higher-level, object-oriented API
- generated from resource description
- uses identifiers and attributes
- has actions (operations on resources)
- exposes subresources and collections

Save your file with
.py extension and run with the "python [filename.py]" command in your terminal.
