Use host networking while building a VSCode devcontainer

Question

How can I get VSCode to use host networking during the build of the container? In devcontainer.json, I can set

"runArgs": ["--network=host"]

but that only applies to running the container. How can I get VSCode to use host networking during the build of the container?

You need to add the following in your devcontainer.json file:

    "build": {
        "args": {
            "network": "host"
        }
    }

This property will allow you to use the host network when building.

I have met a similar problem that I want to use host proxy configuration to build.

I add this in devcontainer.json:

    "build": {
        "args": {
            "HTTP_PROXY": "your_proxy_ip:port",
        }
    }

For other config, you could do the same.

Hope it will be helpful to you.
