转为的overlaybd镜像无法使用，帮忙看看是哪个步骤不对

[jinteng123]

使用这个命令进行转换
/opt/overlaybd/snapshotter/ctr obdconv --fstype "xfs" docker.io/library/redis:6.2.1 localhost:5000/redis:6.2.1_obd_xfs
转为后发现镜像size 为0

nerdctl run --snapshotter=overlaybd localhost:5000/redis:6.2.1_obd_xfs
运行返回这个错误
FATA[0000] failed to prepare extraction snapshot "extract-325776645-qJ5d sha256:c269cf47609c3e3e116f3c3dd4ac6d864c52d36f672f001fb81c0f191c61ee73": failed to attach and mount for snapshot 81262: failed to enable target for /sys/kernel/config/target/core/user_999999999/dev_81262, failed:empty repoBlobUrl: unknown

试试将localhost:5000/redis:6.2.1_obd_xfs先上传至仓库再拉下来使用。
obdconv转换得到的镜像需要先推送到仓库再拉下来，暂时不支持本地转换的镜像直接使用，会有意料之外的各种问题。

EN:
Try uploading localhost:5000/redis:6.2.1_obd_xfs to the repository and pulling it instead of directly using the locally converted image. Locally converted images are not supported for direct use at this time, or unexpected problems may occur.

这个已经可以了，还有一个问题，我想转为成turboOCI这个格式的类型， /opt/overlaybd/snapshotter/convertor -r sea.hub:5000/library -i nginx:1.25.1 --turboOCI nginx:1.25.1_turbo --verbose，仓库用的是自签的证书

报日志是证书不可信任，这个得怎么解决，谢谢

Try to pull commit #237 (the latest version of accelerated-container-image), which supports certification for convertor.

Usage

# Self-signed certificates may require option '--insecure'
--client-cert ${cert-file}:${key-file} --insecure

If it still fails, please let me know.

Besides, if there are any new issues with image conversion, please go to accelerated-container-image and open a new issue in English, so it's easier for the community to refer to it.
