Hi @briantical,

The first part of the error points to the issue:

Error: Datasource.Execute failed: No image matching found

This data source is used look up the ID of an existing DigitalOcean image on your account. golden-image-2022.* is just an example. You should use the name of an image already on your account.

Since the image was not found, it can not be referenced latter. This causes the second error:

This object does not have an attribute named "digitalocean-image".

I've opened a PR (#163) that adds some additional detail to the example. Hopefully that makes things a bit more clear.

Let us know if this resolved your issue!
