How do I use Docker --format when the key contains a period?-CodePudding

I have a Docker network with a field that I want to query with docker inspect --format '{{...}}':

[
    {
        "Name": "bridge",
        // ...
        "Options": {
            // ...
            "com.docker.network.bridge.name": "docker0"
        }
    }
]

Because period is used as a delimiter in the --format expression, how can I reference the field above? I can't just say {{.Options.com.docker.network.bridge.name}}

CodePudding user response：

You can use index:

{{index .Options "com.docker.network.bridge.name"}}

This functionality comes from the upstream text/template library.
