# An AWS Lambda Based Function to Copy S3 Objects
With this AWS Lambda function, you can copy objects from a source S3 bucket to one or more target S3 buckets as they are added to the source bucket.
## Configuration
### IAM Role
Create an IAM role with the following policy:
```json
{
"Version": "2012-10-17",
"Statement": [
{
"Sid": "Stmt1430872797000",
"Effect": "Allow",
"Action": [
"s3:GetBucketTagging",
"s3:GetObject",
"s3:PutObject"
],
"Resource": [
"*"
]
},
{
"Sid": "Stmt1430872844000",
"Effect": "Allow",
"Action": [
"cloudwatch:*"
],
"Resource": [
"*"
]
},
{
"Sid": "Stmt1430872852000",
"Effect": "Allow",
"Action": [
"logs:*"
],
"Resource": [
"*"
]
}
]
}
```
### S3 Buckets
1. Ensure you have a source and target bucket. They do not need to reside in the same region.
2. Configure your S3 buckets (see below)
### Using the Release Packages
Release packages can be found on the [Releases](https://github.com/eleven41/aws-lambda-copy-s3-objects/releases) page.
### Building the Lambda Package
1. Clone this repo
```
git clone [email protected]:eleven41/aws-lambda-copy-s3-objects.git
cd aws-lambda-copy-s3-objects
```
2. Install requirements
```
npm install async
npm install aws-sdk
```
3. Zip up the folder using your favourite zipping utility
### Lambda Function
1. Create a new Lambda function.
2. Upload the ZIP package to your lambda function.
3. Add an event source to your Lambda function:
* Event Source Type: S3
* Bucket: your source bucket
* Event Type: Object Created
4. Set your Lambda function to execute using the IAM role you created above.
### Configuration
Configuration is performed by setting tags on the source bucket.
Tag Name | Required
---|---
TargetBucket | Yes
**TargetBucket** - A space-separated list of buckets to which the objects will be copied. Optionally, the bucket names can contain a @ character followed by a region to indicate that the bucket resides in a different region.
For example: `my-target-bucket1 my-target-bucket1@us-west-2 my-target-bucket3@us-east-1`
At this point, if you upload a file to your source bucket, the file should be copied to the target bucket(s).
