Docker --format带有json。多个占位符的特定占位符语法

Question

我正在尝试使用docker ps和json格式命令生成看起来像这样的输出

{"Names":"name"}

docker ps --format '{{json .Names}}'

没有标签的输出{"name"}。

[docker ps --format '{{json .}}'提供所有带有标签的容器信息，但我什么都不想要。

最好基于下面的所有占位符名称，我希望有一个如下所示的输出，其中包含以我选择的顺序选择的字段：

{"ID":"Container ID", "Image":"Image ID", "Names":"name"}

Placeholder Description
.ID Container ID
.Image  Image ID
.Command    Quoted command
.CreatedAt  Time when the container was created.
.RunningFor Elapsed time since the container was started.
.Ports  Exposed ports.
.Status Container status.
.Size   Container disk size.
.Names  Container names.
.Labels All labels assigned to the container.
.Label  Value of a specific label for this container. For example '{{.Label "com.docker.swarm.cpu"}}'
.Mounts Names of the volumes mounted in this container.
.Networks   Names of the networks attached to this container.

您可以使用以下格式：

docker ps --format '{"ID":"{{ .ID }}", "Image": "{{ .Image }}", "Names":"{{ .Names }}"}'

它输出：

{"ID":"ed3c992b7472", "Image": "alpine:3.9", "Names":"wizardly_buck"}
