Looker & LookML Ingestion Guide: Setup

Looker Prerequisites​

To configure ingestion from Looker, you'll first have to ensure you have an API key to access the Looker resources.

Navigate to Admin Panel & click Roles to open Roles Panel.

Looker home page

Create A New Permission Set​

On Roles Panel, click New Permission Set.

Looker new permission set

Set a name for the new permission set (e.g., DataHub Connector Permission Set) and select the following permissions.

LookML Prerequisites​

Follow the below steps to create the GitHub Deploy Key.

Generate a private-public SSH key pair​

ssh-keygen -t rsa -f looker_datahub_deploy_key
# If prompted, don't add a passphrase to the key

This will typically generate two files like the one below.

  • looker_datahub_deploy_key (private key)
  • looker_datahub_deploy_key.pub (public key)

Add Deploy Key to GitHub Repository​

First, log in to GitHub.

Navigate to GitHub Repository -> Settings -> Deploy Keys and add a public key (e.g. looker_datahub_deploy_key.pub) as deploy key with read access.

Looker home page

Make a note of the private key file. You must paste the file's contents into the GitHub Deploy Key field later while configuring ingestion on the DataHub Portal.

Next Steps​

Once you've done all the above steps, it's time to move on to configuring the actual ingestion source within DataHub.
