Extended description

Use docker events to get real-time events from the server. These events differ per Docker object type.

Object types

Containers

Docker containers report the following events:

  • 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

Images

Docker images report the following events:

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

Plugins

Docker plugins report the following events:

  • install
  • enable
  • disable
  • remove

Volumes

Docker volumes report the following events:

  • create
  • mount
  • unmount
  • destroy

Networks

Docker networks report the following events:

  • create
  • connect
  • disconnect
  • destroy

Daemons

Docker daemons report the following events:

  • reload

Limiting, filtering, and formatting the output

Limit events by time

The --since and --until parameters can be Unix timestamps, date formatted timestamps, or Go duration strings (e.g. 10m, 1h30m) computed relative to the client machine’s time. If you do not provide the --since option, the command returns only new and/or live events. Supported formats for date formatted time stamps include RFC3339Nano, RFC3339, 2006-01-02T15:04:05, 2006-01-02T15:04:05.999999999, 2006-01-02Z07:00, and 2006-01-02. The local timezone on the client will be used if you do not provide either a Z or a +-00:00 timezone offset at the end of the timestamp. When providing Unix timestamps enter seconds[.nanoseconds], where seconds is the number of seconds that have elapsed since January 1, 1970 (midnight UTC/GMT), not counting leap seconds (aka Unix epoch or Unix time), and the optional .nanoseconds field is a fraction of a second no more than nine digits long.

Filtering

The filtering flag (-f or --filter) format is of “key=value”. If you would like to use multiple filters, pass multiple flags (e.g., --filter "foo=bar" --filter "bif=baz")

Using the same filter multiple times will be handled as a OR; for example --filter container=588a23dac085 --filter container=a8f7720b8c22 will display events for container 588a23dac085 OR container a8f7720b8c22

Using multiple filters will be handled as a AND; for example --filter container=588a23dac085 --filter event=start will display events for container container 588a23dac085 AND the event type is start

The currently supported filters are:

  • container (container=<name or id>)
  • daemon (daemon=<name or id>)
  • event (event=<event action>)
  • image (image=<tag or id>)
  • label (label=<key> or label=<key>=<value>)
  • network (network=<name or id>)
  • plugin (plugin=<name or id>)
  • type (type=<container or image or volume or network or daemon>)
  • volume (volume=<name or id>)

Format

If a format (--format) is specified, the given template will be executed instead of the default format. Go’s text/template package describes all the details of the format.

If a format is set to {{json .}}, the events are streamed as valid JSON Lines. For information about JSON Lines, please refer to http://jsonlines.org/ .

Examples

Basic example

You’ll need two shells for this example.

Shell 1: Listening for events:

$ docker events

Shell 2: Start and Stop containers:

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

Shell 1: (Again .. now showing events):

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)

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

To exit the docker events command, use CTRL+C.

Filter events by time

You can filter the output by an absolute timestamp or relative time on the host machine, using the following different time syntaxes:

$ docker events --since 1483283804
