Linux入门教程:Docker命令行参考(17) – docker events从服务器获取实时事件,如果没有提供sinc


Usage:  docker events [OPTIONS]   Get real time events from the server   Options:   -f, --filter value   Filter output based on conditions provided (default [])       --help           Print usage       --since string   Show all events created since timestamp       --until string   Stream events until this timestamp

Docker容器报告如下事件：

attach, commit, copy, create, destroy, detach, die, exec_create, exec_detach, exec_start, export, health_status, kill, oom, pause, rename, resize, restart, start, stop, top, unpause, update

Docker镜像报告如下事件：

delete, import, load, pull, push, save, tag, untag

Docker插件(实验)报告如下事件：

install, enable, disable, remove

Docker数据卷报告如下事件：

create, mount, unmount, destroy

Docker网络报告如下事件：

create, connect, disconnect, destroy

Docker daemon报告如下事件：

reload

–since和–until参数可以是与客户端机器时间相对的Unix时间戳，日期格式时间戳或Go duration字符串(如10m,1h30m)。如果没有提供–since选项，这个命令将只返回新的和/或实时事件。支持日期格式时间戳的格式包括RFC3339Nano, RFC3339, 2006-01-02T15:04:05, 2006-01-02T15:04:05.999999999, 2006-01-02Z07:00和2006-01-02。如果你没有在时间戳后提供时区Z或+-00:00，那么就使用客户端的本地时区。

过滤

过滤标志(-f或–filter)格式是“key=value”。如果要使用多个过滤，传递多个标志(如–filter “foo=bar” –filter “bif=baz”)。
使用相同的过滤多次将处理为OR;例如–filter container=588a23dac085 –filter container=a8f7720b8c22将显示588a23dac085或a8f7720b8c22的容器事件。
使用多个过滤将处理为AND;例如–filter container=588a23dac085 –filter event=start将显示容器为588a23dac085且事件类型为start的事件。
目前支持的过滤有：

container (container=) event (event=) image (image=) plugin (experimental) (plugin=) label (label= or label==) type (type=) volume (volume=) network (network=) daemon (daemon=)

示例

需要启两个shell来演示示例。

Shell 1:监听事件

$ docker events

Shell 2:启动和停止容器

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

Shell 1: 将显示刚才的事件

2015-05-12T11:51:30.999999999Z07:00 container start 4386fb97867d (image=ubuntu-1:14.04) 2015-05-12T11:51:30.999999999Z07:00 container die 4386fb97867d (image=ubuntu-1:14.04) 2015-05-12T15:52:12.999999999Z07:00 container stop 4386fb97867d (image=ubuntu-1:14.04) 2015-05-12T15:53:45.999999999Z07:00 container die 7805c1d35632 (image=redis:2.8) 2015-05-12T15:54:03.999999999Z07:00 container stop 7805c1d35632 (image=redis:2.8)

显示从指定时间的过去事件

$ docker events --since 1378216169 2015-05-12T11:51:30.999999999Z07:00 container die 4386fb97867d (image=ubuntu-1:14.04) 2015-05-12T15:52:12.999999999Z07:00 container stop 4386fb97867d (image=ubuntu-1:14.04) 2015-05-12T15:53:45.999999999Z07:00 container die 7805c1d35632 (image=redis:2.8) 2015-05-12T15:54:03.999999999Z07:00 container stop 7805c1d35632 (image=redis:2.8)   $ docker events --since '2013-09-03' 2015-05-12T11:51:30.999999999Z07:00 container start 4386fb97867d (image=ubuntu-1:14.04) 2015-05-12T11:51:30.999999999Z07:00 container die 4386fb97867d (image=ubuntu-1:14.04) 2015-05-12T15:52:12.999999999Z07:00 container stop 4386fb97867d (image=ubuntu-1:14.04) 2015-05-12T15:53:45.999999999Z07:00 container die 7805c1d35632 (image=redis:2.8) 2015-05-12T15:54:03.999999999Z07:00 container stop 7805c1d35632 (image=redis:2.8)   $ docker events --since '2013-09-03T15:49:29' 2015-05-12T11:51:30.999999999Z07:00 container die 4386fb97867d (image=ubuntu-1:14.04) 2015-05-12T15:52:12.999999999Z07:00 container stop 4386fb97867d (image=ubuntu-1:14.04) 2015-05-12T15:53:45.999999999Z07:00 container die 7805c1d35632 (image=redis:2.8) 2015-05-12T15:54:03.999999999Z07:00 container stop 7805c1d35632 (image=redis:2.8)

以下示例输出在最近3分钟内生成的所有事件，与客户端机器当前时间相关。

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