docker-system-events — Get real time events from the server

Synopsis

docker system events [Options]

Description

Get event information from the Docker daemon. Information can include historical information and real-time information.

Docker containers will report the following events:

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

Docker images report the following events:

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

Docker volumes report the following events:

create, mount, unmount, destroy

Docker networks report the following events:

create, connect, disconnect, destroy

Options

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.

Examples

Listening for Docker events

After running docker events a container 786d698004576 is started and stopped (The container name has been shortened in the output below):

# docker events
2015-01-28T20:21:31.000000000-08:00 59211849bc10: (from whenry/testimage:latest) start
2015-01-28T20:21:31.000000000-08:00 59211849bc10: (from whenry/testimage:latest) die
2015-01-28T20:21:32.000000000-08:00 59211849bc10: (from whenry/testimage:latest) stop

Listening for events since a given date

Again the output container IDs have been shortened for the purposes of this document:

# docker events --since '2015-01-28'
2015-01-28T20:25:38.000000000-08:00 c21f6c22ba27: (from whenry/testimage:latest) create
2015-01-28T20:25:38.000000000-08:00 c21f6c22ba27: (from whenry/testimage:latest) start
2015-01-28T20:25:39.000000000-08:00 c21f6c22ba27: (from whenry/testimage:latest) create
2015-01-28T20:25:39.000000000-08:00 c21f6c22ba27: (from whenry/testimage:latest) start
2015-01-28T20:25:40.000000000-08:00 c21f6c22ba27: (from whenry/testimage:latest) die
2015-01-28T20:25:42.000000000-08:00 c21f6c22ba27: (from whenry/testimage:latest) stop
2015-01-28T20:25:45.000000000-08:00 c21f6c22ba27: (from whenry/testimage:latest) start
2015-01-28T20:25:45.000000000-08:00 c21f6c22ba27: (from whenry/testimage:latest) die
2015-01-28T20:25:46.000000000-08:00 c21f6c22ba27: (from whenry/testimage:latest) stop

The following example outputs all events that were generated in the last 3 minutes, relative to the current time on the client machine:

# 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  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

If you do not provide the --since option, the command returns only new and/or live events.

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.

# docker events --filter 'type=container' --format 'Type={{.Type}}  Status={{.Status}}  ID={{.ID}}'
Type=container  Status=create  ID=2ee349dac409e97974ce8d01b70d250b85e0ba8189299c126a87812311951e26

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/⟩ .
