Dokku Event Logs

New as of 0.3.21

Docker provides an events command to show system's real time events. Likewise, Dokku can record events as syslog entries and also provides a plugin to display the last ones.

events [-t]                                      Show the last events (-t follows)
events:list                                      List logged events
events:on                                        Enable events logger
events:off                                       Disable events logger

Usage

Enable the plugin:

$ dokku events:on
Enabling dokku events logger

Dokku will then write log entries to /var/log/syslog as well as a Dokku-specific logs sub-directory /var/log/dokku/events.log, which can be easily displayed with the command dokku events:
