无法使用 Skopeo 将 docker 镜像复制到 ZOT 注册表

Question

我已经按照this文档安装了Zot注册表版本v2.0.1。注册表已成功安装并且我看到它正在运行。现在我想使用 Skopeo 将图像从本地目录复制到 Zot 注册表。为此，我安装了 Skopeo 版本 1.15.0。 现在我正在尝试使用以下命令将 docker 映像从本地目录复制到 Zot 注册表

skopeo copy --debug --insecure-policy --dest-tls-verify=false docker-archive://home/nginx/nginx-docker.tar docker://127.0.0.1:8080/nginx:latest

但是我收到以下错误

我尝试查看 Zot 注册表的日志，但找不到任何内容。由于某些原因，ping 操作效果不佳。有什么帮助吗？

Answer 1

zot 是仅限 OCI 的注册表，因此

skopeo copy --format=oci ...
