@samruddhikhandale Thank you!

I hope this one will be prioritized. We experiencing a big dev experience issue working with inner loop env with a k8s cluster within the Codespaces. Every 3rd run fails, and we required to do full container rebuild.. sometimes multiple.

Can you add a test that verifies that the retries are working as expected? Left one comment about a breaking change. At minimum, this feels like a minor version bump to me since adding retries on the docker start is a new feature.

@jkeech Thanks for the review! Added a test which tests the retry logic and bumped the minor version. Also, see #637 (comment)
