Docker远程API过滤器已退出 [英] Docker Remote API Filter Exited

问题描述

我在Docker Remote API文档中看到，过滤器可以用于过滤状态，但我不确定如何形成请求：

https://docs.docker.com/reference/api/docker_remote_api_v1.16/#list容器

  GET / containers / json？filters = status [exited] 
  

应如何格式化以显示只有退出的容器？

解决方案

jwodder 是过滤器上的错误，但是我想逐步了解一下，因为我不熟悉Go数据类型。

是指为过滤器使用一个 map [string] [] string ，这是一个Go map（哈希表）

• map [string] 定义一个类型为 string




• [] string 是地图中的值。切片
  [] 是一个没有固定长度的数组。然后切片由
  string 值组成。

所以API需要一个包含字符串的数组的哈希映射。此 Go Playground 演示了汇总Go过滤器数据：

  mapS：= map [string] [] string {status：[] string {exited}} 
  

进入JSON：

  {status ：[exited]} 
  

所以将JSON添加到Docker API请求中： p>

  GET / containers / json？all = 1& filters = {％22status％22：[％22exited％22]} 
  

all = 1 包含报告退出的容器

如果他们刚刚记录了JSON，那么非Go人可能会更容易API的结构：/

I see in the Docker Remote API Docs that filter can be used to filter on status but I'm unsure how to form the request:

https://docs.docker.com/reference/api/docker_remote_api_v1.16/#list-containers

GET /containers/json?filters=status[exited] ?????

How should this be formatted to display ONLY exited containers?

解决方案

jwodder is correct on the filter but I wanted to go through this step by step as I wasn't familiar with the Go data types.

The Docker API documentation refers to using a map[string][]string for a filter, which is a Go map (hash table)

• map[string] defines a map with keys of type string

• []string is the type definition for the values in the map. A slice [] is an array without fixed length. Then the slice is made up of string values.

So the API requires a hash map of arrays containing strings. This Go Playground demonstrates marshalling the Go filter data:

mapS := map[string][]string{ "status":[]string{"exited"} }

Into JSON:

{ "status": [ "exited" ] }

So adding that JSON to the Docker API request you get:

GET /containers/json?all=1&filters={%22status%22:[%22exited%22]}

all=1 is included to report exited containers (like -a on the command line).

It might be easier for non Go people if they just documented the JSON structure for the API : /
