My notes

Usecase

mount log files output by the dokcer container on the host, and rotate the log files using host OS logrotated.

Step

# docker run --name nginx \
  -d \
  --publish 80:80 \
  --volume /opt/docker/nginx:/etc/nginx/conf \
  --volume /var/log/nginx:/var/log/nginx \
  nginx:latest

# touch /etc/logrotate.d/nginx.logrotate
# vi /etc/logrotate.d/nginx.logrotate
# cat /etc/logrotate.d/nginx.logrotate
/var/log/nginx/*log {
