How to enable logrotation for traefik?

问题

How do I enable log rotation for log files e.g. access.log.

Is this built in ?

Docs only say "This allows the logs to be rotated and processed by an external program, such as logrotate"

Log Rotation

Traefik will close and reopen its log files, assuming they're configured, on receipt of a USR1 signal. This allows the logs to be rotated and processed by an external program, such as logrotate.

If you are running Traefik in a Docker container then you can do something like this:

Check that logrotate is installed

logrotate --version

Create file in /etc/logrotate.d/

vi /etc/logrotate.d/traefik

Put the following script, do not forget to fill with the container name.

/var/log/traefik/*.log {
  size 10M
  rotate 5
  missingok
  notifempty
  postrotate
    docker kill --signal="USR1" <container-name>
  endscript
}

Run!

logrotate /etc/logrotate.conf --debug 
logrotate /etc/logrotate.conf

It seems like theres no logrotation built-in so i enabled logration on the Host that the access.log is mounted to.

My logrotate-config for traefik 1.7.4 running in a container with volume mount to "/opt/traefik/logs":

/opt/traefik/logs/*.log {
  daily
  rotate 30
  missingok
  notifempty
  compress
  dateext
  dateformat .%Y-%m-%d
  create 0644 root root
  postrotate
   docker kill --signal="USR1" $(docker ps | grep traefik | awk '{print $1}')
  endscript
 }
