如何编辑现有的docker图像元数据? [英] How can I edit an existing docker image metadata?
问题描述
出于以下原因，我要编辑docker图像元数据:
I would like to edit a docker images metadata for the following reasons:
-
我不喜欢图像父母EXPOSE，VOLUME等声明(请参阅# 3465 ，Docker-Team不想提供解决方案)，所以我想取消体积"或不暴露"图像.
I don't like an image parents EXPOSE, VOLUME etc declaration (see #3465, Docker-Team did not want to provide a solution), so I'd like to "un-volume" or "un-expose" the image.
我不喜欢图像ContainerConfig(请参阅docker inspect [image])，因为它是使用docker commit [container]
I dont't like an image ContainerConfig (see docker inspect [image]) cause it was generated from a running container using docker commit [container]
在docker build或docker run期间修复错误，例如:
cannot mount volume over existing file, file exists [path]
Fix error durring docker build or docker run like:
cannot mount volume over existing file, file exists [path]
有什么办法可以做到吗?
Is there any way I can do that?
推荐答案
虽然有点黑，但可以:
-
将图像保存到tar.gz文件:
$ docker save [image] > [targetfile.tar.gz]
Save the image to a tar.gz file:
$ docker save [image] > [targetfile.tar.gz]
提取tar文件以访问原始图像数据:
tar -xvzf [targetfile.tar.gz]
Extract the tar file to get access to the raw image data:
tar -xvzf [targetfile.tar.gz]
在manifest.json文件中查找图像元数据文件:应该有一个像.Config这样的键，其中包含一个[HEX]数字.提取的文件夹的根目录中应该有一个精确的[HEX].json.
这是包含图像元数据的文件.根据需要进行编辑.
Lookup the image metadata file in the manifest.json file: There should be a key like .Config which contains a [HEX] number. There should be an exact [HEX].json in the root of the extracted folder.
This is the file containing the image metadata. Edit as you like.
将提取的文件打包回new.tar.gz存档
Pack the extracted files back into an new.tar.gz-archive
使用cat [new.tar.tz] | docker load重新导入修改后的图像
Use cat [new.tar.tz] | docker load to re-import the modified image
使用docker inspect [image]验证您的元数据更改已应用
Use docker inspect [image] to verify your metadata changes have been applied
