从Docker注册表中删除映像后，无法将新映像推送到注册表

Question

我正在Ubuntu 16.04上使用v2版本。我的配置文件看起来像这样-

    version: 0.1
    log:
      fields:
        service: registry
    storage:
      cache:
        blobdescriptor: inmemory
      filesystem:
        rootdirectory: /var/lib/registry
      delete:
        enabled: true
    http:
  addr: :5000
  headers:
    X-Content-Type-Options: [nosniff]
health:
  storagedriver:
    enabled: true
    interval: 10s
    threshold: 3

我正在运行以下命令序列

# docker pull busybox
Using default tag: latest
latest: Pulling from library/busybox
8c5a7da1afbc: Pull complete

# docker tag busybox localhost:5000/busybox:1.0.0

# docker push localhost:5000/busybox:1.0.0
The push refers to repository [localhost:5000/busybox]

从本地删除图像

# docker rmi e1ddd7948a1c -f

获取摘要

# curl -v --silent -H "Accept: application/vnd.docker.distribution.manifest.v2+json" -X GET localhost:5000/v2/busybox/manifests/1.0.0 2>&1 | grep Docker-Content-Digest | awk '{print ($3)}'

删除图片

# curl -v -H "Accept: application/vnd.docker.distribution.manifest.v2+json" -X DELETE localhost:5000/v2/busybox/manifests/sha256:5e8e0509e829bb8f990249135a36e81a3ecbe94294e7a185cc14616e5fad96bd

清理blob（运行垃圾收集器）

# docker exec registry bin/registry garbage-collect /etc/docker/registry/config.yml

删除后，要拉出新的busybox图片

# docker pull busybox

# docker tag busybox localhost:5000/busybox:1.0.0

# docker push localhost:5000/busybox:1.0.0
The push refers to repository [localhost:5000/busybox]
f9d9e4e6e2f0: Layer already exists
1.0.0: digest: sha256:5e8e0509e829bb8f990249135a36e81a3ecbe94294e7a185cc14616e5fad96bd size: 527

  

Docker push说fslayer已经存在

# docker rmi e1ddd7948a1c -f

docker pull localhost:5000/busybox:1.0.0

> Error response from daemon: manifest for localhost:5000/busybox:1.0.0
> not found

# curl -v --silent -H "Accept: application/vnd.docker.distribution.manifest.v2+json" -X GET localhost:5000/v2/busybox/manifests/1.0.0

It gives 404 Not Found

  

删除后，我必须重新启动注册表。

重新启动注册表后，相同的忙碌框拉标签和推图像工作正常。

我不明白为什么每次都必须重新启动注册表。为什么“推忙箱”图像显示fslayers已经存在，并且成功执行并从注册表中拉出失败。

请您告诉您删除图像而不必每次都重新启动注册表
