This article provides a detailed walkthrough of connecting to S3-compatible storage via the Amazon S3 API on an Ubuntu system.You’ll discover how to install the required tools, set up a Python script for seamless interaction with the storage, and execute key operations such as retrieving a list of buckets, uploading files, and downloading data. Every step is thoroughly detailed, making it easy for beginners to confidently set up and test the connection without any prior experience.
Installing Python and pip
Start by updating your system and installing Python 3 along with pip:
sudo apt update sudo apt install python3 python3-pip python3 -m pip install --upgrade pipInstalling the boto3 Library
Next, install the boto3 library, which facilitates working with S3-compatible storage:
pip3 install boto3Creating the Python Script
Create a new file (e.g., s3_client.py) using your preferred text editor:
import boto3
from botocore.client import Config
# Replace these placeholders with your credentials
access_key = 'YOUR_ACCESS_KEY'
secret_key = 'YOUR_SECRET_KEY'
endpoint_url = 'https://your.endpoint.url'
# Initialize the S3 client
s3_client = boto3.client(
's3',
aws_access_key_id=access_key,
aws_secret_access_key=secret_key,
endpoint_url=endpoint_url,
config=Config(signature_version='s3')
)
# Example: List buckets
try:
response = s3_client.list_buckets()
print("Buckets:")
for bucket in response['Buckets']:
print(f" - {bucket['Name']}")
except Exception as e:
print(f"Error: {e}")
Save the changes and exit the editor (use Ctrl + X, then press Y and Enter).
Running the Script
Run the script with the following command:
python3 s3_client.pyIf configured correctly, you’ll see a list of buckets in your storage.
Additional Storage Operations
Creating a Test File
To test file uploads and downloads, create a test file:
echo "Example file content" > local_file.txt
Uploading a File
Add the following line to your script to upload the file:
s3_client.upload_file('local_file.txt', 'bucket_name', 'remote_file.txt') local_file.txt is the path to the local file. bucket_name is the name of the target bucket. remote_file.txt is the file name in the storage.
Downloading a File
Similarly, add this line to download the file:
s3_client.download_file('bucket_name', 'remote_file.txt', 'local_file.txt')- bucket_name is the name of the bucket.
- remote_file.txt is the name of the file in storage.
- local_file.txt is the path where the file will be saved.
Dependency Troubleshooting
If you encounter errors, ensure all dependencies are up to date. For example, you can manually update botocore:
pip3 install --upgrade botocoreNotes
If you don’t have an S3-compatible storage service configured, check with your provider for the necessary endpoint_url, access keys, and bucket settings. You can use alternative text editors such as vim or any editor you’re comfortable with. Ensure that your user account has the required permissions to create and manage files in the S3 storage.
This guide ensures a seamless setup process, empowering users to efficiently connect and interact with S3-compatible storage.
