总之:我想删除一个docker镜像，但是如果我这样做，它告诉我不能删除，因为镜像正在被运行的容器使用。但是据我所知，根本没有容器在运行。
详细:我调用docker images -a来查看调用图像。这样我就确定了我想要删除的图像ID，并调用docker image rm {ID}，其中{ID}是应该删除的字符串(它适用于其他图像，所以到目前为止我很有信心)。我得到了响应:
来自守护进程的错误响应:冲突:无法删除{ID}(不能强制)-映像正在被运行容器08815cd48523使用(最后的ID似乎随着每次调用而改变)
这个错误似乎很容易理解，但如果我调用docker ps -a，它告诉我，我没有一个容器运行，因此没有容器运行与指定的ID。
某些图像出现此问题。但似乎都与Kubernetes有关。有人知道是什么问题吗?
在评论中听到docker检查一个不可见的容器(我用"removed_for_post"替换了所有我不确定它是否包含敏感数据的部分):

您的容器似乎是由其他工具如docker-compose创建的，因为我猜它是在您的计算机上的本地。
这意味着你不能很容易地用docker rm语句停止它的创建。
EDIT 1 - Kubernetes
- 您似乎正在使用docker桌面
- 您的容器似乎是
etcd，这是kubernetes主系统的一部分(非常重要):
k8s_POD_etcd-docker-desktop_kube-system_ Removed_for_post
所以，由于它是kubernetes组件的一部分，只有当你不想使用kubernetes时，你才应该删除它。
通过删除kubernetes或etcd pod。
如果是docker-desktop，应该没有问题。
总结，your container is created by a pod which is a resource handled by kubernetes
docker-compose
- 找到你的docker-compose目录，通常容器名称以项目名称开头，然后进入它的目录。
- execute
docker-compose down
码头工人
- 尝试重新启动docker守护进程。例如，在基于Linux的环境中:
sudo systemctl restart docker - 重启你的机器应该也能工作。
最后，您应该能够按照您的问题所建议的删除容器。
