Prerequisites for running the Quickstart

This section helps you to examine the list of actions you must perfom before you start working on your function.

Get the CRN (Customer Resource Number) of the flow definiton.
1. Download the flow definition for this use case and upload it into your Cloudera DataFlow Catalog.
2. Once you have the flow definition in the Catalog, copy its CRN with its version.
  For example:crn:cdp:df:us-west-1:558bc1d3-8867-4357-8524-311d51289233:flow:Resize-Image/v.1
note
Make sure you have the full CRN with the flow version as the end. For more information, see Retrieving data flow CRN.
Make sure that you have a Cloudera machine user created.

This machine user is used when the function is triggered to retrieve the flow definition to be executed. For more information, see Creating CDP service account.
Give the Cloudera machine user the appropriate role and generate the necessary keys.

For more information, see Provisioning Access Key ID and Private Key.
Download the Cloudera DataFlow Functions binary from the Functions page of Cloudera DataFlow for the cloud provider of your choice.

note
This quickstart leverages the CLI of the cloud providers to make deploying the function straightforward. If you want to deploy your function using the control plane UI of the cloud provider, see the appropriate section of the Cloudera DataFlow Functions documentation. The instructions provided in this quickstart are based on using the CLI of the cloud provider.
