docker强制删除镜像

前言

在搭建k8s集群的时候，由于master主机需要一系列的组件，例如kube-apiserver, kube-proxy, kube-controller-manager, etcd等。

这些都是以docker容器形式运行的，所以需要提前拉取。

但是，由于某些原因吧，k8s没有拉起来。在检查的时候发现docker镜像出了问题。于是我就去删除它们，但是删除的时候也出了错误：

检查

经过查阅资料，我发现必须强制删除它们。

可以使用一下两种方法：

使用-f选项强制删除，即docker rmi -f image-id. 使用镜像的仓库路径来删除，即docker rmi repository:tag.

两种方法我都试了一下，发现方法1比方法2管用，方法2删除不成功，于是是用方法1来删除。

可是我有很多镜像，一个一个删就到明年了。于是我就是用awk来批量删除了。

[root@node1 ~]# for tag in $(docker images|awk '{print $3}') > do > docker rmi -f ${tag} > done [root@node1 ~]# docker images REPOSITORY TAG IMAGE ID CREATED SIZE

后记

我很奇怪为什么这套环境不能搭建成功k8s服务（在其他环境都可以），可能确实是网络环境问题吧，嘎嘎嘎~
