Question

如何从IBM Cloud Private 2.1.0中的注册表中删除图像？在1.2中，您可以从UI中删除图像。如何在当前版本中完成？

Answer 1

我编写了一个脚本来帮助通过CLI删除图像。它允许您根据jq CLI包含的模式删除ICP注册表中的图像。此脚本旨在在ICP主节点上运行。保存片段，chmod + x，更新你的信誉的vars并享受！

示例调用：

./ remove-registry-image.sh label
   结果 ::删除名称空间或图像中包含该标签的所有图像

   ./remove-registry-image.sh namespace / image-label
   结果 ::删除位于命名空间
中的特定图像标签

#!/bin/bash

#   
#   usage ./remove-registry-image.sh filterString

#   ./remove-registry-image.sh nameSpace/textString

Answer 2

是的，在2.1.0中删除图像无法通过UI完成。 UI将在以后的版本中恢复该功能。对于即将发布的版本，您可以通过API执行此操作。知识中心文档将为此更新信息。

Answer 3

直接从docker CLI

首先列出它们：

docker images

删除其中一个：

docker rmi -f the-image-id

删除所有这些：

docker rmi -f $(docker images -a -q)
