Hi @wzshiming. Thanks for your PR.

I'm waiting for a containerd 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.

Your PR branch is 200+ commits behind upstream main; the CI configuration for the CircleCI vagrant runs is out of date and can't run properly until you rebase your branch

@estesp Thank you, updated.

How about adding defer w.Close() after calling OpenWriter()?

@kzys the content/local store might return the error from Close. If we use defer here, we need to update the returned error value if necessary. Since there are not too much if branch, the change is good 😊
