码头工人事件
描述
从服务器获取实时事件
用法
$ docker events [OPTIONS]
扩展说明
用于docker events
从服务器获取实时事件。这些事件因Docker对象类型而异。不同的事件类型具有不同的范围。仅在发生作用域的节点上可以看到本地作用域事件,而在所有管理器上都可以看到群集作用域事件。
仅返回最后的1000个日志事件。您可以使用过滤器来进一步限制返回的事件数。

限制,过滤和格式化输出
按时间限制事件
的--since
和--until
参数可以是Unix的时间戳,日期格式时间戳,或转到持续时间串(例如10m
,1h30m
相对于客户机的时间计算的)。如果不提供该--since
选项,则该命令仅返回新事件和/或实时事件。支持的格式为日期格式时间戳包括RFC3339Nano,RFC3339, ,2006-01-02T15:04:05
,
2006-01-02T15:04:05.999999999
,2006-01-02Z07:00
和2006-01-02
。如果您未提供Z
或,
则将使用客户端上的本地时区+-00:00
时间戳记末尾的时区偏移量。提供Unix时间戳时,请输入seconds [.nanoseconds],其中seconds是自1970年1月1日(UTC / GMT午夜)以来经过的秒数,不计算leap秒(又名Unix纪元或Unix时间),以及可选的。纳秒字段是一秒的分数,长度不超过9位数。
仅返回最后的1000个日志事件。您可以使用过滤器来进一步限制返回的事件数。
筛选
过滤标志(-f
或--filter
)的格式为“键=值”。如果您想使用多个过滤器,请传递多个标志(例如
--filter "foo=bar" --filter "bif=baz"
)
多次使用同一个过滤器将被视为或; 例如
--filter container=588a23dac085 --filter container=a8f7720b8c22
将显示容器588a23dac085或容器a8f7720b8c22的事件
使用多个过滤器将作为AND处理;例如
--filter container=588a23dac085 --filter event=start
将显示事件容器容器588a23dac085与事件类型是开始
当前支持的过滤器是:
- 配置(
config=<name or id>
) - 容器(
container=<name or id>
) - 守护程序(
daemon=<name or id>
) - 事件(
event=<event action>
) - 图片(
image=<repository or tag>
) - 标签(
label=<key>
或label=<key>=<value>
) - 网络(
network=<name or id>
) - 节点(
node=<id>
) - 插件(
plugin=<name or id>
) - 范围(
scope=<local or swarm>
) - 机密(
secret=<name or id>
) - 服务(
service=<name or id>
) - 类型(
type=<container or image or volume or network or daemon or plugin or service or node or secret or config>
) - 音量(
volume=<name>
)
格式
如果--format
指定了格式(),则将执行给定的模板,而不是默认格式。Go的文本/模板包描述了格式的所有细节。
如果将格式设置为{{json .}}
,则事件将作为有效的JSON行流式传输。有关JSON行的信息,请访问http://jsonlines.org/。
有关此命令的示例用法,请参阅下面的示例部分。
选项
名称,简写 | 默认 | 描述 |
--filter , -f |
根据提供的条件过滤输出 | |
--format |
使用给定的Go模板格式化输出 | |
--since |
显示自时间戳记以来创建的所有事件 | |
--until |
流事件直到该时间戳 |
例子
基本例子
在此示例中,您将需要两个shell。
外壳1:监听事件:
$ docker events
外壳2:启动和停止容器:
$ docker create --name test alpine:latest top
$ docker start test
$ docker stop test
Shell 1 :(再次..现在显示事件):
2017-01-05T00:35:58.859401177+08:00 container create 0fdb48addc82871eb34eb23a847cfd033dedd1a0a37bef2e6d9eb3870fc7ff37 (image=alpine:latest, name=test)

2017-01-05T00:36:09.890214053+08:00 container stop 0fdb...ff37 (image=alpine:latest, name=test)
要退出docker events
命令,请使用CTRL+C
。
按时间过滤事件
您可以使用以下不同的时间语法在主机上按绝对时间戳或相对时间来过滤输出:
