docker - 如何在 Docker API 中使用挂载创建容器

问题描述

目前使用 Docker API 的 1.37v 创建带有挂载的容器的方法是什么：

https://docs.docker.com/engine/api/v1.37/#operation/ContainerCreate

以下失败：

{
    "AttachStdin": false,
    "AttachStdout": true,
    "AttachStderr": true,
    "Tty": true,
    "Env": [
        "string"
    ],
    "Cmd": [
        "ls"
    ],
    "WorkingDir": "/wix-fed-scripts",
    "Labels": {
        "stav": true
    },
    "Image": "stavalfi/node7",

    // Addint this secion cause error
    "Volumes": {
        "Source": "/folder1",
        "Target": "/folder2",
        "Type": "bind",
        "ReadOnly": false
    }
}

错误：（HTTP 代码 500）服务器错误 - json：无法将字符串解组到 Go 结构字段 ContainerConfigWrapper.Volumes 类型的 struct {}

解决方案

我使用 docker 客户端的代理来监视 REST 请求。

要创建具有匿名卷的容器，请使用该Volumes字段

docker run -v /temp ubuntu

JSON 字段：

"Volumes": {
    "temp": {}
 },

要创建主机卷，请使用该HostConfig字段

docker run -v /path_on_host:/path_in_container ubuntu

HostConfig领域：

"HostConfig": {
    "Binds": [
      "/path_on_host:/path_in_container"
    ],
    ...
}

对于命名卷

docker run -v name:/path/in/container ubuntu

JSON：

"HostConfig": {
    "Binds": [
      "name:/path/in/container"
    ],
    ...
}

/v1.37/containers/create可以缩减的匿名卷的完整 POST 请求 JSON ：
