本文档概述了 V0插件配置的格式。这里描述的插件配置是在v1.12.0版本的 Docker 守护进程中引入的。
插件配置描述了 docker 插件的各种组件。插件配置可以使用以下媒体类型序列化为 JSON 格式：
配置类型 | 媒体类型 |
|---|---|
配置 | “应用程序/ vnd.docker.plugin.v1 + JSON” |
Config 提供了在注册表中使用 V0插件格式的基本可访问字段。
description 插件的字符串描述
documentation 字符串 链接到关于插件的文档
interface PluginInterface 接口由插件实现，结构由下列字段组成
- **`types`** _string array_ types indicate what interface(s) the plugin currently implements. currently supported:
- **docker.volumedriver/1.0**
- **docker.networkdriver/1.0**
- **docker.ipamdriver/1.0**
- **docker.authz/1.0**
- **docker.logdriver/1.0**
- **docker.metricscollector/1.0**
- **`socket`** _string_ socket is the name of the socket the engine should use to communicate with the plugins. the socket will be created in /run/docker/plugins.
entrypoint 插件的字符串数组入口点，请参阅ENTRYPOINT
workdir 插件的字符串 workdir，请参阅WORKDIR
network 插件的 PluginNetwork 网络，结构由以下字段组成
- **`type`** _string_ network type. currently supported:**bridge** - **host** - **none**
mounts 插件的 PluginMount 数组装载，结构由以下字段组成，请参阅MOUNTS
- **`name`** _string_ name of the mount.

ipchost 布尔型访问主机 ipc 命名空间。
pidhost 布尔访问主机 pid 名称空间。
propagatedMount 字符串 路径作为 rshared 挂载，以便在该路径下挂载对 docker可见。这对于卷插件很有用。这条路径将被绑定到插件 rootfs 的 outisde，所以它的内容在升级时被保留。
env 插件的 PluginEnv 数组 env，结构由以下字段组成
- **`name`** _string_ name of the env.
- **`description`** _string_ description of the env.
- **`value`** _string_ value of the env.
args PluginArgs 插件的参数，结构由以下字段组成

- **`value`** _string array_ values of the args.
linux PluginLinux
- **`capabilities`** _string array_ capabilities of the plugin (Linux only), see list here
- **`allowAllDevices`** _boolean_ If /dev is bind mounted from the host, and allowAllDevices is set to true, the plugin will have rwm access to all devices on the host.
