Docker运行报错:layer不存在

我试图在我的树莓派3上使用docker-compose设置redmine(与postgres)。它已经工作了一次，但后来我试图安装插件，不知何故设法破坏了我的系统。

现在它不再让我启动数据库容器了。即使创建一个新的postgres:12.8容器，也会产生错误layer does not exist:

$ docker run --rm -it postgres:12.8 bash
docker: Error response from daemon: layer does not exist.

我已经重新启动了系统两次，遗憾的是没有改变任何东西。我怎样才能让它再次工作?

删除图像(通过docker rmi)不能停止错误。

$ docker run --rm -it postgres:12.8 bash

其他图像可以正常运行:

Nuking/var/lib/docker似乎使系统再次工作-这将删除所有图像和许多其他与docker相关的数据。

这感觉不像是一个很好的解决方案，但现在必须这样做。

$ sudo service docker stop
$ docker ps

我有下面的错误和重启docker守护进程似乎修复它。我还不知道是什么原因导致的

level=error msg=" POST/v1.41/containers/create的Handler返回错误:layer不存在">

重新启动docker守护进程:

sudo systemctl restart docker

我迟到了，但也许我的答案可以帮助某人在未来。下面是我遇到的问题:

突然几个(3)我的容器，包括portainer停止工作。在使用docker容器再次运行容器时，导致层未找到错误。
使用docker的容器列表
使用docker Image ls列出的映像没有列出与三个停止的容器相关的三个映像。
尝试拉新图像不工作

latest: Pulling from portainer/portainer-ce
Digest: sha256:9fa1ec78b4e29d83593cf9720674b72829c9cdc0db7083a962bc30e64e27f64e
Status: Image is up to date for portainer/portainer-ce:latest

试图使用docker image rm删除图像导致以下错误:

Error response from daemon: unrecognized image ID sha256:a87d51c7a32408ba63e65888d023ad7d4328fd575d8a4c8bd8cffa495fcd055c

解决方案

在上面列出的图像删除过程中记录sha256 id，在我的示例中，对于portainer，图像的sha256 id为a87d51c7a32408ba63e65888d023ad7d4328fd575d8a4c8bd8cffa495fcd055c
导航到/var/lib/docker/image/overlay2/imagedb/content/sha256并删除/移动与sha256 ID相同名称的文件
尝试使用docker image pull命令再次拉取映像。现在应该可以了。
运行容器/撰写文件
对所有违规图片重复此过程。

这是一个有点繁琐的过程，特别是对于很多图像，但它比nuking/var/lib/docker目录要好。

如果肯·安德森的方法适合你，可以选择:对我来说，它发生在redis:alpine。和docker run -it redis:alpine以"layer not found"。

$ docker run -it redis:alpine
docker: Error response from daemon: layer does not exist.

我没有容器，没有图像显示:

docker container ls -a|grep redis返回nothing

docker images | grep redis返回nothing

只是手动重新拉图像(docker pull redis:alpine)对我有效。
