如何在Docker映像中删除配置卷

问题描述

我使用 docker run -it -v / xx1 -v / xx2 [image] / bin / bash 创建一个容器。

然后提交映像并推送到docker hub。

Then commit to image and push to docker hub.

使用 docker inspect [image]

音量的详细信息是

"Volumes": {
            "/xx1": {},
            "/xx2": {}
        },

现在，我要在此图像中删除卷 / xx1 。

Now I want to remove volume /xx1 in this image.

我该怎么办？

推荐答案

我认为使用Docker工具现在。您不能从正在运行的容器中删除卷，或者如果要将映像用作新Dockerfile中的基础，则不能删除继承的卷。

I don't think this is possible with the Docker tools right now. You can't remove a volume from a running container, or if you were to use your image as the base in a new Dockerfile you can't remove the inherited volumes.

可能的话，您可以使用JérômePetazzoni的 nsenter 工具手动删除容器内的安装架，然后提交。您可以使用该方法，但是需要做一些相当低级的黑客操作。

Possibly you could use Jérôme Petazzoni's nsenter tool to manually remove the mount inside the container and then commit. You can use that approach to attach a volume to a running container, but there's some fairly low-level hacking needed to do it.
