Hi @kevinwlau. Thanks for your PR.

I'm waiting for a helm member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes/test-infra repository.

should this be a major version bump?

I'm not sure how to get my gcloud key file into the CircleCI testing environment as a file for use in

charts/test/repo-sync.sh

Line 54 in cc1cfc1

gcloud auth activate-service-account --key-file <(base64 --decode <<< "$SYNC_CREDS")

should this be a major version bump?

I saw a few other PRs that bumped up the minor version for similar changes
