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？

答

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。您可以使用该方法将卷附加到正在运行的容器，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.
