从 Nexus 3 Docker-Registry 拉入或推入时出现 MissingBlobException

Question

我正在使用 Nexus 3.5.0-02 和两个 Docker 存储库。一种用于快照，一种用于发布。快照存储库工作正常。但从昨天开始，当我尝试从发布存储库中拉取或推送 Docker 映像时，我得到了

MissingBlobException

。

并非每个 Docker 镜像存储库都会出现此问题。但是，如果它发生在某些图像上，则无法拉或推该图像。我发现，当我推送镜像时出现这个异常，Docker镜像的一层无法存储。

我无法解释 Nexus 内部发生的事情。但有没有解决这个问题的方法或解决办法？

Answer 1

我在 Nexus 上的 Maven 存储库也遇到了同样的问题

3.7.1-02

。就我而言，是快照存储库损坏了。

Blob efs-maven-snapshots@A8699C1C-BF3D1E08-7499E994-765D71F0-8D62CAF3:4eb114a2-a83f-4601-b40e-d582f198a75f exists in metadata, but is missing from the blobstore

我设法通过 Nexus GUI 删除存储库、保留 Blob 存储，然后再次创建存储库来修复此问题。
