$ pants package ::                                
10:18:36.00 [INFO] Completed: Pulling Docker image `ubuntu` because the image is missing locally.
10:18:36.00 [ERROR] 1 Exception encountered:

Engine traceback:
  in `package` goal

IntrinsicError: Failed to pull image `ubuntu`: Failed to pull Docker image 
`ubuntu`: DockerStreamError { error: "toomanyrequests: You have reached 
your pull rate limit. You may increase the limit by authenticating and 
upgrading: <https://www.docker.com/increase-rate-limit>" }

after logging in to Docker hub in the terminal, the error persists anyway. I wonder if there are multiple (redundant) processes that are spawned and attempt to pull the image at the same time resulting in the rate limit violation. Pants version 2.16.0 and latest 2.18.0.dev1 OS Linux Additional info Doing

docker pull ubuntu

first before running a Pants goal works fine pulling the image. pantsbuild/pants
