# NAME
docker-events - Get real time events from the server
# SYNOPSIS
**docker events**
[**--help**]
[**-f**|**--filter**[=*[]*]]
[**--since**[=*SINCE*]]
[**--until**[=*UNTIL*]]
[**--format**[=*FORMAT*]]
# 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
**--help**
Print usage statement
**-f**, **--filter**=[]
Provide filter values (i.e., 'event=stop')
**--since**=""
Show all events created since timestamp
**--until**=""
Stream events until this timestamp
**--format**=""
Format the output using the given go template
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
Type=container Status=attach ID=2ee349dac409e97974ce8d01b70d250b85e0ba8189299c126a87812311951e26
Type=container Status=start ID=2ee349dac409e97974ce8d01b70d250b85e0ba8189299c126a87812311951e26
Type=container Status=resize ID=2ee349dac409e97974ce8d01b70d250b85e0ba8189299c126a87812311951e26
Type=container Status=die ID=2ee349dac409e97974ce8d01b70d250b85e0ba8189299c126a87812311951e26
Type=container Status=destroy 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/ .
# docker events --format '{{json .}}'
