What
Pull the quickstart image with retries and exponential backoff before
docker runstarts it.Why
docker runpulls the image if needed but gives up after a single attempt, so transient network errors fail the workflow job. For example:See these types of failures show up in a variety of places and I have been slowly adding retries each place it happens to reduce build flakiness.
