从Docker容器获取Runc config.json [英] Getting runc config.json from docker container

问题描述

我正在尝试从docker容器创建一个runc容器.

I am trying to create a runc container from a docker container.

我关注了此博客文章，并成功地从运行docker容器.

I followed this blog post and was successfull in extracting the config.json from the running docker container.

问题是

1. 我找到config.json的路径与我在网上找到的引用不同
2. 据我所知，同一路径在具有相同docker版本的其他主机上不起作用.在该主机上，我无法找到config.json的生成位置.

关于在哪里可以找到config.json的信息，我有冲突，并且无法在主机上找到它.

I have conflicting information on where to find the config.json, and am unable to find it on my host.

|config.json location                     | source                         |
|-----------------------------------------|--------------------------------------------|
|/run/docker/libcontainerd/<container id> | http://crunchtools.com/getting-ninja-runc/ |
|/var/run/docker/libcontainerd/<container id> |https://github.com/genuinetools/riddler |
|/var/run/docker/containerd/daemon/io.containerd.runtime.v1.linux/moby/<container id> | my host #1 |
| ??? | my host #2 |

我还可以检查其他哪些位置，以及如何确定将要位于哪个位置?是否在某处进行了配置，这是否取决于docker，contained，runc或其他版本的版本?

What other locations can I check, and how can I tell which one it will be? Is this configured somewhere, does this depend on the version of docker, containerd, runc, or something else?

推荐答案

@ lin.qian的答案为我节省了时间.config.json现在位于/run/containerd/io.containerd.runtime.v1.linux/moby/中，而不是问题帖子中提到的所有其他位置.

@lin.qian 's answer saves me hours. config.json is now located in /run/containerd/io.containerd.runtime.v1.linux/moby/ rather than all the other locations mentioned in the question post.

实际上，如果您进一步想将此配置文件与runc一起使用，则需要进行修改

Actually if you further want to use this config file with runc, you need modify

• root

并从安装"中删除以下内容

and remove the following from "mounts"

• "/etc/hosts"
• "/etc/hostname"
• "/dev/shm"

并删除钩子"
