我试图在已创建的podman容器中添加网络。 这些是我采取的步骤：

• 创建并启动容器：

podman run -it --name "container" --network=mgmtnet img_v1 /bin/bash

• 容器启动。
• 我现在停止容器

    podman stop container

• 我在以下位置编辑podman config.json文件： /var/lib/containers/storage/overlay-containers/60dfc044f28b0b60f0490f351f44b3647531c245d1348084944feaea783a6ad5/userdata/config.json

我在“名称空间”部分添加了一个额外的netns路径。

"namespaces": [
            {
                "type": "pid"
            },{
                "type": "network",>>              "path": "/var/run/netns/cni-8231c733-6932-ed54-4dee-92477014da6e",>>[+]           "path": "/var/run/netns/test_net"
            },{
                "type": "ipc"
            },{
                "type": "uts"
            },{
                "type": "mount"
            }
        ],

• 我启动容器

podman start container

我期望容器中的更改（一个额外的接口）。但这不会发生。另外，检查config.json时，发现更改已消失。

因此启动容器将删除config中的更改。如何克服这个问题？
