如何在Dockerfile中删除卷 [英] How to remove a volume in a Dockerfile

问题描述

我遇到了与此处相同的问题: mkdir .ssh在Dockerfile中，文件夹不存在吗?

I'm experiencing the same problem as found here: mkdir .ssh in a Dockerfile, folder is not there?

我想知道我的dockerfile是否可以删除其父声明的卷?

I'm wondering if there is a way for my dockerfile to remove a volume declared by its parent?

我的理由是:该卷已声明要装入外部数据库，我正在创建的映像用于测试目的，并且包含该卷内部的数据.理想情况下，我不想在我的入口点填充它，因为这是一项昂贵的操作.

My reasoning for this is that; the volume was declared to mount to an external database, the image I'm creating is for testing purposes and contains the data present for the volume internally. Ideally I don't want to have to populate this in my entry point as it's an expensive operation.

实际上，在使用生产中的图像进行修改以进行测试时，我确实有一个非常相似的用例.唯一的机会是修改父图像的元数据.根据需要，我为此创建了一个小脚本，请查看 docker-copyedit 可以帮助您.

Actually I did have a very similar use case in using an image from production that would be modified for testing. The only chance is to modify the metadata of the parent image. As I need to that regulary, I have created a little script for that, have a look at docker-copyedit if that can help you.
