Basic S3 Bucket Operations with AWS CLI
Creating S3 Buckets
```bash
Create a bucket in the default region
aws s3 mb s3://my-unique-bucket-name
Create a bucket in a specific region
aws s3 mb s3://my-unique-bucket-name --region eu-west-1
Create multiple buckets
for bucket in bucket1 bucket2 bucket3; do
aws s3 mb s3://my-company-$bucket
done
```
Listing S3 Buckets and Contents
```bash
List all buckets
aws s3 ls
List contents of a specific bucket
aws s3 ls s3://my-bucket-name
List contents with details (size, date)
aws s3 ls s3://my-bucket-name --human-readable --summarize
List contents recursively
aws s3 ls s3://my-bucket-name --recursive
List with specific prefix
aws s3 ls s3://my-bucket-name/folder/
```
Uploading Files and Directories
```bash
Upload a single file
aws s3 cp /path/to/local/file.txt s3://my-bucket-name/
Upload with custom name
aws s3 cp /path/to/local/file.txt s3://my-bucket-name/new-name.txt
Upload entire directory
aws s3 cp /path/to/directory s3://my-bucket-name/remote-folder/ --recursive
Upload with specific storage class
aws s3 cp file.txt s3://my-bucket-name/ --storage-class GLACIER
Upload with server-side encryption
aws s3 cp file.txt s3://my-bucket-name/ --sse AES256
```
Downloading Files and Directories
```bash
Download a single file
aws s3 cp s3://my-bucket-name/file.txt /path/to/local/directory/
Download entire directory
aws s3 cp s3://my-bucket-name/remote-folder/ /path/to/local/directory/ --recursive
Download with include/exclude filters

Download only newer files
aws s3 sync s3://my-bucket-name/folder/ /local/folder/
```
Synchronizing Directories
```bash
Sync local directory to S3
aws s3 sync /local/directory/ s3://my-bucket-name/remote-folder/
Sync S3 to local directory
aws s3 sync s3://my-bucket-name/remote-folder/ /local/directory/
Sync with delete (remove files not in source)
aws s3 sync /local/directory/ s3://my-bucket-name/remote-folder/ --delete
Sync with specific file patterns
aws s3 sync /local/directory/ s3://my-bucket-name/ --exclude "" --include ".pdf"
```
Deleting Files and Buckets
```bash
Delete a single file
aws s3 rm s3://my-bucket-name/file.txt
Delete multiple files with prefix
aws s3 rm s3://my-bucket-name/folder/ --recursive
Delete bucket (must be empty first)
aws s3 rb s3://my-bucket-name
Force delete bucket with contents
aws s3 rb s3://my-bucket-name --force
```
Advanced AWS CLI Operations
Working with Bucket Policies
```bash
Get bucket policy
aws s3api get-bucket-policy --bucket my-bucket-name

)
Method 3: Using session
session = boto3.Session(profile_name='default')
s3_client = session.client('s3')
```
Creating and Managing Buckets
```python
import boto3
from botocore.exceptions import ClientError
def create_bucket(bucket_name, region='us-west-2'):
"""Create an S3 bucket"""
try:
s3_client = boto3.client('s3', region_name=region)
if region == 'us-east-1':
# us-east-1 doesn't need LocationConstraint
s3_client.create_bucket(Bucket=bucket_name)
else:
s3_client.create_bucket(
Bucket=bucket_name,
CreateBucketConfiguration={'LocationConstraint': region}
)
print(f"Bucket {bucket_name} created successfully")
return True
except ClientError as e:
print(f"Error creating bucket: {e}")
return False
def list_buckets():
"""List all S3 buckets"""
s3_client = boto3.client('s3')
try:
response = s3_client.list_buckets()
print("Existing buckets:")
for bucket in response['Buckets']:
print(f" {bucket['Name']} (Created: {bucket['CreationDate']})")
except ClientError as e:
print(f"Error listing buckets: {e}")
def delete_bucket(bucket_name):
"""Delete an empty S3 bucket"""
s3_client = boto3.client('s3')
try:
s3_client.delete_bucket(Bucket=bucket_name)
print(f"Bucket {bucket_name} deleted successfully")
return True
except ClientError as e:
print(f"Error deleting bucket: {e}")
return False
```
File Upload and Download Operations
```python
import boto3
import os
from pathlib import Path
def upload_file(file_path, bucket_name, object_name=None):
"""Upload a file to S3 bucket"""
if object_name is None:
object_name = os.path.basename(file_path)
s3_client = boto3.client('s3')
try:
s3_client.upload_file(file_path, bucket_name, object_name)
print(f"File {file_path} uploaded to {bucket_name}/{object_name}")
return True
except ClientError as e:
print(f"Error uploading file: {e}")
return False
def download_file(bucket_name, object_name, file_path):
"""Download a file from S3 bucket"""
s3_client = boto3.client('s3')
try:
s3_client.download_file(bucket_name, object_name, file_path)
print(f"File {object_name} downloaded to {file_path}")
return True
except ClientError as e:
print(f"Error downloading file: {e}")
return False
def upload_directory(directory_path, bucket_name, prefix=''):
"""Upload entire directory to S3"""
s3_client = boto3.client('s3')
directory = Path(directory_path)
for file_path in directory.rglob('*'):
if file_path.is_file():
relative_path = file_path.relative_to(directory)
s3_key = f"{prefix}{relative_path}".replace('\\', '/')
try:
s3_client.upload_file(str(file_path), bucket_name, s3_key)
print(f"Uploaded: {file_path} -> s3://{bucket_name}/{s3_key}")
except ClientError as e:
print(f"Error uploading {file_path}: {e}")

BACKUP_DIR="/path/to/backup"
S3_BUCKET="my-backup-bucket"
DATE=$(date +%Y%m%d_%H%M%S)
LOG_FILE="/var/log/s3_backup.log"
Function to log messages
log_message() {
echo "$(date '+%Y-%m-%d %H:%M:%S') - $1" | tee -a "$LOG_FILE"
}
Create backup directory if it doesn't exist
mkdir -p "$BACKUP_DIR"
Compress files
log_message "Starting backup compression..."
tar -czf "$BACKUP_DIR/backup_$DATE.tar.gz" /important/data/ 2>/dev/null
if [ $? -eq 0 ]; then
log_message "Compression completed successfully"
else
log_message "Error during compression"
exit 1
fi
Upload to S3
log_message "Uploading to S3..."
aws s3 cp "$BACKUP_DIR/backup_$DATE.tar.gz" "s3://$S3_BUCKET/backups/"
if [ $? -eq 0 ]; then
log_message "Upload completed successfully"
# Clean up local backup
rm "$BACKUP_DIR/backup_$DATE.tar.gz"
log_message "Local backup file cleaned up"
else
log_message "Error during S3 upload"
exit 1
fi
log_message "Backup process completed"
```
Python Script for Monitoring S3 Usage
```python
#!/usr/bin/env python3
import boto3
import json
from datetime import datetime, timedelta
class S3Monitor:
def __init__(self):
self.s3_client = boto3.client('s3')
self.cloudwatch = boto3.client('cloudwatch')
def get_bucket_sizes(self):
"""Get size information for all buckets"""
bucket_info = []
try:
buckets = self.s3_client.list_buckets()['Buckets']
for bucket in buckets:
bucket_name = bucket['Name']
# Get bucket size from CloudWatch
end_time = datetime.utcnow()
start_time = end_time - timedelta(days=2)
response = self.cloudwatch.get_metric_statistics(
Namespace='AWS/S3',
MetricName='BucketSizeBytes',
Dimensions=[
{'Name': 'BucketName', 'Value': bucket_name},
{'Name': 'StorageType', 'Value': 'StandardStorage'}
],
StartTime=start_time,
EndTime=end_time,
Period=86400,
Statistics=['Average']
)
size_bytes = 0
if response['Datapoints']:
size_bytes = response['Datapoints'][-1]['Average']
bucket_info.append({
'name': bucket_name,
'size_bytes': size_bytes,
'size_gb': round(size_bytes / (10243), 2),
'creation_date': bucket['CreationDate']
})
except Exception as e:
print(f"Error getting bucket sizes: {e}")
return bucket_info
def generate_report(self):
"""Generate comprehensive S3 report"""
report = []
report.append("S3 Monitoring Report")
report.append("=" * 50)
report.append(f"Generated: {datetime.now().strftime('%Y-%m-%d %H:%M:%S')}")
report.append("")
# Bucket sizes
report.append("Bucket Sizes:")
report.append("-" * 20)
bucket_info = self.get_bucket_sizes()
total_size = 0
for bucket in bucket_info:
report.append(f"{bucket['name']}: {bucket['size_gb']} GB")
total_size += bucket['size_gb']
report.append(f"\nTotal Storage: {total_size:.2f} GB")
return "\n".join(report)
if __name__ == "__main__":
monitor = S3Monitor()
report = monitor.generate_report()
print(report)
```
Troubleshooting Common Issues
Authentication Problems
Issue: "Unable to locate credentials"
```bash
Solution 1: Check AWS credentials
aws configure list
Solution 2: Verify environment variables
echo $AWS_ACCESS_KEY_ID
echo $AWS_SECRET_ACCESS_KEY
Solution 3: Check credentials file
cat ~/.aws/credentials
```
Issue: "Access Denied" errors
```bash
Check IAM permissions
aws iam get-user
aws iam list-attached-user-policies --user-name your-username
Test specific permissions
aws s3 ls s3://test-bucket --debug
```
Network and Connectivity Issues
Issue: Slow upload/download speeds
```bash
Use multipart uploads for large files
aws s3 cp large-file.zip s3://my-bucket/ --cli-write-timeout 0
Configure multipart threshold
aws configure set default.s3.multipart_threshold 64MB
aws configure set default.s3.multipart_chunksize 16MB
```
Issue: SSL certificate errors
```bash
Update certificates
sudo apt update && sudo apt install ca-certificates
For development only: disable SSL verification
aws s3 ls --no-verify-ssl
```
Bucket and Object Issues
Issue: "Bucket name not available"
```bash
Bucket names must be globally unique
Try adding timestamp or random string
BUCKET_NAME="my-bucket-$(date +%s)"
aws s3 mb s3://$BUCKET_NAME
```
Issue: "The bucket you are attempting to access must be addressed using the specified endpoint"
```bash
Specify correct region
aws s3 ls s3://my-bucket --region eu-west-1
```
Best Practices and Security Tips
Security Best Practices
1. Use IAM Roles Instead of Access Keys
```bash
Create IAM role for EC2 instances
aws iam create-role --role-name S3AccessRole --assume-role-policy-document file://trust-policy.json
aws iam attach-role-policy --role-name S3AccessRole --policy-arn arn:aws:iam::aws:policy/AmazonS3ReadOnlyAccess
```
2. Enable MFA for Sensitive Operations
```bash
Configure MFA device
aws iam create-virtual-mfa-device --virtual-mfa-device-name username --outfile QRCode.png --bootstrap-method QRCodePNG
aws iam enable-mfa-device --user-name username --serial-number arn:aws:iam::123456789012:mfa/username --authentication-code1 123456 --authentication-code2 789012
```
3. Use Bucket Policies and ACLs Carefully
```json
{
"Version": "2012-10-17",
"Statement": [
{
"Sid": "DenyInsecureConnections",
"Effect": "Deny",
"Principal": "*",
"Action": "s3:*",
"Resource": [
"arn:aws:s3:::my-bucket",
"arn:aws:s3:::my-bucket/*"
],
"Condition": {
"Bool": {
"aws:SecureTransport": "false"
}
}
}
]
}
```
4. Enable Server-Side Encryption
```bash
Enable default encryption
aws s3api put-bucket-encryption --bucket my-bucket --server-side-encryption-configuration '{
"Rules": [
{
"ApplyServerSideEncryptionByDefault": {
"SSEAlgorithm": "AES256"
}
}
]
}'
```
Monitoring and Logging
1. Enable S3 Access Logging
```bash
Enable access logging
aws s3api put-bucket-logging --bucket my-bucket --bucket-logging-status '{
"LoggingEnabled": {
"TargetBucket": "my-log-bucket",
"TargetPrefix": "access-logs/"
}
}'
Get logging status
aws s3api get-bucket-logging --bucket my-bucket
```
2. Set Up CloudTrail for API Logging
```bash
Create CloudTrail for S3 API calls
aws cloudtrail create-trail --name s3-api-trail --s3-bucket-name my-cloudtrail-bucket --include-global-service-events
aws cloudtrail start-logging --name s3-api-trail
```
3. Configure CloudWatch Metrics
```bash
Enable request metrics
aws s3api put-bucket-metrics-configuration --bucket my-bucket --id EntireBucket --metrics-configuration '{
"Id": "EntireBucket",
"Filter": {"Prefix": ""},
"IncludeTags": false
}'
```
Performance Optimization Tips
1. Use Appropriate Storage Classes
```bash
Standard for frequently accessed data
aws s3 cp file.txt s3://my-bucket/ --storage-class STANDARD
IA for infrequently accessed data
aws s3 cp file.txt s3://my-bucket/ --storage-class STANDARD_IA
Glacier for archival
aws s3 cp file.txt s3://my-bucket/ --storage-class GLACIER
Deep Archive for long-term archival
aws s3 cp file.txt s3://my-bucket/ --storage-class DEEP_ARCHIVE
```
2. Implement Lifecycle Policies
```bash
Create comprehensive lifecycle policy
cat > lifecycle-policy.json << EOF
{
"Rules": [
{
"ID": "ComprehensiveLifecycle",
"Status": "Enabled",
"Filter": {"Prefix": "data/"},
"Transitions": [
{
"Days": 30,
"StorageClass": "STANDARD_IA"
},
{
"Days": 90,
"StorageClass": "GLACIER"
},
{
"Days": 365,
"StorageClass": "DEEP_ARCHIVE"
}
],
"Expiration": {
"Days": 2555
}
}
]
}
EOF
aws s3api put-bucket-lifecycle-configuration --bucket my-bucket --lifecycle-configuration file://lifecycle-policy.json
```
3. Optimize Transfer Performance
```bash
Configure for better performance
aws configure set default.s3.max_concurrent_requests 20
aws configure set default.s3.multipart_threshold 8MB
aws configure set default.s3.multipart_chunksize 8MB
aws configure set default.s3.max_bandwidth 100MB/s
Use transfer acceleration
aws s3api put-bucket-accelerate-configuration --bucket my-bucket --accelerate-configuration Status=Enabled
```
Cost Optimization Strategies
1. Monitor Storage Costs
```python
#!/usr/bin/env python3
import boto3
from datetime import datetime, timedelta
def analyze_storage_costs():
ce_client = boto3.client('ce')
end_date = datetime.now().date()
start_date = end_date - timedelta(days=30)
response = ce_client.get_cost_and_usage(
TimePeriod={
'Start': start_date.strftime('%Y-%m-%d'),
'End': end_date.strftime('%Y-%m-%d')
},
Granularity='MONTHLY',
Metrics=['BlendedCost'],
GroupBy=[
{'Type': 'DIMENSION', 'Key': 'SERVICE'},
],
Filter={
'Dimensions': {
'Key': 'SERVICE',
'Values': ['Amazon Simple Storage Service']
}
}
)
for result in response['ResultsByTime']:
for group in result['Groups']:
service = group['Keys'][0]
cost = group['Metrics']['BlendedCost']['Amount']
print(f"{service}: ${float(cost):.2f}")
if __name__ == "__main__":
analyze_storage_costs()
```
2. Set Up Billing Alerts
```bash
Create SNS topic for billing alerts
aws sns create-topic --name billing-alerts
Create billing alarm
aws cloudwatch put-metric-alarm \
--alarm-name "S3-Billing-Alert" \
--alarm-description "Alert when S3 costs exceed $100" \
--metric-name EstimatedCharges \
--namespace AWS/Billing \
--statistic Maximum \
--period 86400 \
--threshold 100 \
--comparison-operator GreaterThanThreshold \
--dimensions Name=ServiceName,Value=AmazonS3 \
--evaluation-periods 1
```
