用法

Usage: docker events [OPTIONS]

Get real time events from the server

-f, --filter=[]    Filter output based on conditions provided
--help=false       Print usage
--since=           Show all events created since timestamp
--until=           Stream events until this timestamp

作用

events 命令用于打印 Docker 容器内实时的系统事件。

示例

第一个窗口用来监听事件：

$ docker events

第二个窗口起停容器：

$ docker start 4386fb97867d
$ docker stop 4386fb97867d
$ docker stop 7805c1d35632

执行完后，shell 窗口会同步打印如下信息：

2014-05-10T17:42:14.999999999Z07:00 4386fb97867d: (from ubuntu-1:14.04) start
2014-05-10T17:42:14.999999999Z07:00 4386fb97867d: (from ubuntu-1:14.04) die
2014-05-10T17:42:14.999999999Z07:00 4386fb97867d: (from ubuntu-1:14.04) stop
2014-05-10T17:42:14.999999999Z07:00 7805c1d35632: (from redis:2.8) die
2014-05-10T17:42:14.999999999Z07:00 7805c1d35632: (from redis:2.8) stop

使用 since 参数按时间筛选：

$ sudo docker events --since 1378216169
2014-03-10T17:42:14.999999999Z07:00 4386fb97867d: (from ubuntu-1:14.04) die
2014-05-10T17:42:14.999999999Z07:00 4386fb97867d: (from ubuntu-1:14.04) stop
2014-05-10T17:42:14.999999999Z07:00 7805c1d35632: (from redis:2.8) die
2014-03-10T17:42:14.999999999Z07:00 7805c1d35632: (from redis:2.8) stop
$ sudo docker events --since '2013-09-03'
2014-09-03T17:42:14.999999999Z07:00 4386fb97867d: (from ubuntu-1:14.04) start
2014-09-03T17:42:14.999999999Z07:00 4386fb97867d: (from ubuntu-1:14.04) die
2014-05-10T17:42:14.999999999Z07:00 4386fb97867d: (from ubuntu-1:14.04) stop
2014-05-10T17:42:14.999999999Z07:00 7805c1d35632: (from redis:2.8) die
2014-09-03T17:42:14.999999999Z07:00 7805c1d35632: (from redis:2.8) stop
$ sudo docker events --since '2013-09-03T15:49:29'
2014-09-03T15:49:29.999999999Z07:00 4386fb97867d: (from ubuntu-1:14.04) die
2014-05-10T17:42:14.999999999Z07:00 4386fb97867d: (from ubuntu-1:14.04) stop
2014-05-10T17:42:14.999999999Z07:00 7805c1d35632: (from redis:2.8) die
2014-09-03T15:49:29.999999999Z07:00 7805c1d35632: (from redis:2.8) stop

只保留三分钟内的事件：

$ sudo docker events --since '3m'
2015-05-12T11:51:30.999999999Z07:00 4386fb97867d: (from ubuntu-1:14.04) die
2015-05-12T15:52:12.999999999Z07:00 4 4386fb97867d: (from ubuntu-1:14.04) stop
2015-05-12T15:53:45.999999999Z07:00  7805c1d35632: (from redis:2.8) die
2015-05-12T15:54:03.999999999Z07:00  7805c1d35632: (from redis:2.8) stop

也可以使用过滤器筛选：

$ docker events --filter 'event=stop'
2014-05-10T17:42:14.999999999Z07:00 4386fb97867d: (from ubuntu-1:14.04) stop
2014-09-03T17:42:14.999999999Z07:00 7805c1d35632: (from redis:2.8) stop
$ docker events --filter 'image=ubuntu-1:14.04'
2014-05-10T17:42:14.999999999Z07:00 4386fb97867d: (from ubuntu-1:14.04) start
2014-05-10T17:42:14.999999999Z07:00 4386fb97867d: (from ubuntu-1:14.04) die
2014-05-10T17:42:14.999999999Z07:00 4386fb97867d: (from ubuntu-1:14.04) stop
$ docker events --filter 'container=7805c1d35632'
