docker - RPC 错误 : code = Unknown desc = error pulling image configuration: unknown blob when pull docker image

Question

我正在通过 kubernetes 集群中的 nexus 3 从本地 docker 注册表提供程序中提取图像，但抛出此错误:

Failed to pull image "192.168.31.2:8080/goharbor/harbor-portal:v2.0.1": rpc error: code = Unknown desc = error pulling image configuration: unknown blob

当我在 k8sslave3 主机中使用 docker 执行此命令时:

[root@k8sslave3 ~]# sudo docker pull 192.168.31.2:8080/goharbor/harbor-portal:v2.0.1
v2.0.1: Pulling from goharbor/harbor-portal

error pulling image configuration: unknown blob

我读了 the question并告诉我 docker 镜像不存在。但是当我执行 pull in 192.168.31.2 时，输出如下:

[dolphin@localhost docker]$ sudo docker pull 192.168.31.2:8080/goharbor/harbor-portal:v2.0.1
[sudo] password for dolphin: 
v2.0.1: Pulling from goharbor/harbor-portal

192.168.31.2:8080/goharbor/harbor-portal:v2.0.1

所以现在我很困惑，我应该怎么做才能解决这个问题？这是 nexus 存储库中的 docker 镜像:

I am read the question and tell me the docker image does not exists.But when I execute pull in 192.168.31.2, the output like this:

[dolphin@localhost docker]$ sudo docker pull 192.168.31.2:8080/goharbor/harbor-portal:v2.0.1
[sudo] 海豚密码:
v2.0.1:从 goharbor/harbor-portal 拉取

状态:图像是最新的 192.168.31.2:8080/goharbor/harbor-portal:v2.0.1
192.168.31.2:8080/goharbor/harbor-portal:v2.0.1

如果您从托管注册表的主机中提取镜像，则可以预期它会起作用。
当您从该主机创建标签时，Docker 客户端不需要从私有(private)注册表中提取任何内容，它会直接从主机的本地 Docker 注册表返回镜像。
看消息:

Status: Image is up to date for192.168.31.2:8080/goharbor/harbor-portal:v2.0.1

您的图像配置/数据很可能在注册表中已损坏。
尝试重新上传它并检查它的大小是否太大(有时几个 GB 可能太多)，因为它可能会在注册表上传/存储时造成一些麻烦。
