Amazon S3 Toolkit

The Amazon S3 Toolkit is a workflow node. Its tools include S3 List Objects, S3 Upload Text, S3 Upload File, and S3 Read File, plus 6 more listed below. Create a connection before you use any of these tools. Type @ in a field when the value should come from an earlier step.

Authentication

Create an Amazon S3 connection before you use any of these tools.

Set up credentials in Amazon S3

1. Open IAM, Users and select or create a user.
2. Open Security credentials, then Create access key, and copy the Access Key ID and Secret Access Key.
3. Open Permissions and attach the AmazonS3FullAccess policy.
4. In S3, Buckets, note the bucket name this workflow should use.

Connect the credentials in EKB

1. On the first Amazon S3 node, open Connection.
2. Click + New.
3. Enter a Connection Name.
4. Paste the Access Key ID and Secret Access Key.
5. Choose a Region. The default is us-east-1.
6. Default Bucket and Custom Endpoint are optional. Use the bucket name from S3, and leave the endpoint blank for Amazon S3.
7. Select the new connection in Select saved connection.

Enter token manually saves the same credentials on that node instead of a saved connection.
