AWS S3: Put Node

The AWS S3: Put Node allows a workflow to upload a file into an S3 bucket.

Node Properties

There are three main configuration sections for the AWS S3: Put Node …

Credential Configuration

AWS S3: Put Node Credentials

There are two options for configuring credentials:

  • Choose a Service Credential: Retrieves your AWS credentials from the selected service credential.

    • Credential Name Template: Choose which of your application’s AWS service credentials you would like to use. Note: Service credentials are not accessible from Edge Workflows, so only direct configuration is available for them. This field is templatable.
  • Enter Connection Info: Configure the AWS credentials directly within the node. All fields are required.

    • AWS Region Template: The AWS region to connect to. This field is templatable.
    • AWS Access Key ID Template: The AWS access key ID associated with the AWS account you wish to use. This field is templatable.
    • AWS Secret Access Key Template: The AWS secret access key associated with the AWS account you wish to use. This field is templatable.

We recommend that you create an AWS Key/Secret pair specifically for use in the Workflow Engine - a key that only has access to the proper AWS S3 buckets. We also recommend that you store these values as service credentials.

AWS Permissions

In order to perform a put operation, the AWS user must have, at minimum, the following IAM Policy:

  "Version": "YYYY-MM-DD",
  "Statement": [
      "Effect": "Allow",
      "Action": ["s3:PutObject"],
      "Resource": ["arn:aws:s3:::<bucket-name>/*"]

File Configuration

Next is to configure the fields required by S3. All applicable fields are templatable:

  • Bucket Name: (Required) The S3 bucket to upload to.
  • File Name: (Required) The name of the file to upload, including the extension. If you wish to upload the file to a subdirectory within the bucket, the path to the file should be included in this field. (e.g. “path/to/my/file.ext”)
  • File Encoding: (Required) The encoding of the data being uploading. Defaults to UTF-8.
  • File Type: (Required) MIME type of the file being uploaded.
  • Server-Side Encryption: Enables AES-256 encryption on the uploaded file. See docs.

File Contents

There are two different ways to input the contents of your file. Both are templatable:

AWS S3: Put Node File Content

  • File Content: The content to upload. If left blank, your configured file will be uploaded without any content.

AWS S3: Put Node File URL

  • File URL: (Required) The URL where the file you wish to upload can be found. This option is useful when using the Temporary URL Output option in a notebook.

For Edge Workflows, the ability to upload via URL is only available in GEA version 1.23.0 and higher.

Result Path
