用起来不是很稳定

拉 gcr.io 的镜像也有问题

[test@dockerhost ~]$ docker pull gcr.xxx.us.kg/kaniko-project/executor:debug
Error response from daemon: Head "https://gcr.xxx.us.kg/v2/kaniko-project/executor/manifests/debug": Get "https://gcr.io/v2/token?scope=repository%3Akaniko-project%2Fexecutor%3Apull&service=gcr.io": dial tcp 142.250.107.82:443: i/o timeout

拉 其它的，比如 quay.io 、registry.k8s.io 等的镜像就没问题
