Hacking Go-TFE and Fetching All Workspaces in Terraform Enterprise: A Journey Through Pagination

Terraform Enterprise (TFE) allows for the automation of infrastructure management, providing collaboration, governance, and self-service workflows. To interact with TFE's API, the go-tfe library can be used. Listing workspaces in TFE using the library encounters a pagination issue, where the API returns a limited number of results per request. To retrieve all workspaces, manual pagination is necessary, involving repeated requests with increasing page numbers. The solution involves initializing an empty workspace slice, setting the page number to 1, and entering a pagination loop. Within the loop, requests are made using ListOptions with the page number and maximum page size. Returned workspaces are appended to the allWorkspaces slice. The loop terminates when the number of workspaces returned is less than the page size, indicating the last page has been reached. The complete list of workspaces is then returned. Understanding and handling pagination correctly is crucial when working with APIs that support it. Consider default page sizes, maximum page sizes, and loop termination to avoid infinite loops. Managing pagination ensures the stability and reliability of automation pipelines.
