**Lambda Exporter — AWS Lambda Functions Export Utility**
This script exports all AWS Lambda functions (code and configuration) from your account to a local directory, for backup, migration, or auditing.
---
**Requirements**
- Python 3.7+
- `boto3`
- AWS credentials configured (via CLI, environment variables, or IAM role)
Install:
```bash
pip install boto3
```
---
**Usage**
1. **Default (uses default AWS profile and region `us-east-1`)**
```python
exporter = LambdaExporter()
exporter.export_all_functions()
```
2. **Custom profile and region**
```python
exporter = LambdaExporter(profile_name='my-profile', region_name='eu-west-1')
exporter.export_all_functions(base_dir='backups')
```
3. **Run directly**
Save as `lambda_exporter.py` and run:
```bash
python lambda_exporter.py
```
---
**Output Structure**
```
lambda_export/
└── export_YYYYMMDD_HHMMSS/
├── FunctionName1/
│ ├── configuration.json
│ └── [extracted source files...]
├── FunctionName2/
│ ├── configuration.json
│ └── function_code.bin # if not a ZIP
└── export_summary.json
```
- ZIP-based functions are fully extracted.
- `configuration.json` contains runtime, memory, timeout, env vars, role, etc.
- `export_summary.json` logs total functions and success count.
---
**Required IAM Permissions**
```json
{
"Version": "2012-10-17",
"Statement": [
{
"Effect": "Allow",
"Action": [
"lambda:ListFunctions",
"lambda:GetFunction",
"lambda:GetFunctionConfiguration"
],
"Resource": "*"
}
]
}
```
---
**Important Notes**
- The script is read-only — it does not modify any AWS resources.
- Environment variables (including secrets) are included in `configuration.json`. Handle exports securely and avoid committing them to version control.
- Pre-signed download URLs are used immediately, so expiration is not an issue for typical function sizes.
