In the dockerfiles repo, each of the supported projects has a create dockerfile and an update dockerfile. The former is used to create an image, while the latter is occasionally run to perform an “incremental update” (pulling in updates to the source repository and binary artifacts as another layer).
I know that the create dockerfile is run on the Docker Hub or on CircleCI (depending on the project’s needs).
Where is the update dockerfile run? I can see that the Circle and Hub configuration both don’t mention these files.
