使用时间选择性过滤输出

--since 和 --until参数可以使用 Unix时间戳，日期格式化的时间戳，或者 相对时间 来计算和过滤的时间依赖宿主机的时间。

如果没有提供--since 选项，则只显示最新或者实时的事件。

支持的日期时间格式有RFC3339Nano,RFC3339 ,2006-01-02T15:04:05,2006-01-02T15:04:05.999999999 , ` 2006-01-02Z07:00 , 2006-01-02` 。

如果没有在时间戳后显性的指定时区，就像z或者a +-00:00时区偏移，会使用默认的本地时区。

当提供Unix时间戳时，例如： seconds[.nanoseconds]，其中 seconds 秒是从 1970年1月1日0时0分0秒开始统计的一个数字，不包括闰秒。其中可选的[.nanoseconds]是纳秒部分，他的长度不超过9位数。

使用标准事件过滤输出

过滤标志 -f 或者 --filter 格式是 key=value 形式。如果同时使用多条过滤器(filters)，可以多次指定，例如：--filter "foo=bar" --filter "bif=baz"

如果使用同类型事件标志的多个过滤器时，他们之前的是 OR 的关系，例如：--filter container=588a23dac085 --filter container=a8f7720b8c22 2个容器的事件都会过滤出来。

使用不同类型的事件标志的多个过滤器时，他们之前的是AND的关系，例如：--filter container=588a23dac085 --filter event=start 将只显示容器588a23dac085 且 event 是 start 的事件。

当前支持的过滤器（filters）有

  • config (config=)
  • container (container=)
  • daemon (daemon=)
  • event (event=)
  • image (image=)
  • label (label= or label==)
  • network (network=)
  • node (node=)
  • plugin (plugin=)
  • scope (scope=)
  • secret (secret=)
  • service (service=)
  • type (type=)
  • volume (volume=)

格式化输出

如果指定了 --format 格式化输出，将使用 go的模板替代默认的输出信息。如果使用 {{json .}} 结果将会以json的格式输出。

帮助

# docker events --help

Usage: docker events [OPTIONS]

Get real time events from the server

Options:
  -f, --filter filter Filter output based on conditions provided
      --format string Format the output using the given Go template
      --since string Show all events created since timestamp
      --until string Stream events until this timestamp

选项

| 选项,简写 | 默认值 | 描述 | | – | – | – | | -f, –filter | | 根据条件过滤output输出信息 | | –format | | 使用 Go 模板的方式格式显示 output 输出信息 | | –since | | 显示从指定时间戳之后的所有的事件 | | –until | | 显示到指定时间戳为止的所有事件 |

示例

实时监听事件

需要开启2个shell终端进行本示例的验证演示

shell1：监听事件

$ docker events

shell2: 启动和停止容器

$ docker create --name test alpine:latest top
$ docker start test
$ docker stop test

返回shell1查看

2017-01-05T00:35:58.859401177+08:00 container create 0fdb48addc82871eb34eb23a847cfd033dedd1a0a37bef2e6d9eb3870fc7ff37 (image=alpine:latest, name=test)
2017-01-05T00:36:04.703631903+08:00 network connect e2e1f5ceda09d4300f3a846f0acfaa9a8bb0d89e775eb744c5acecd60e0529e2 (container=0fdb...ff37, name=bridge, type=bridge)
2017-01-05T00:36:04.795031609+08:00 container start 0fdb...ff37 (image=alpine:latest, name=test)
2017-01-05T00:36:09.830268747+08:00 container kill 0fdb...ff37 (image=alpine:latest, name=test, signal=15)

2017-01-05T00:36:09.890214053+08:00 container stop 0fdb...ff37 (image=alpine:latest, name=test)

退出docker events命令使用快捷键 CTRL+C

使用时间过滤事件

时间时间戳来源于当前容器宿主机的时钟。 使用时间过滤输出时可以使用绝对的时间戳，或者相对的时间。 不同的时间过滤语法示例如下：

$ docker events --since 1483283804
