Move redmine logs to /var/log about docker-redmine HOT 16 CLOSED

@b-a-t will do.

from docker-redmine.

VOLUME please

from docker-redmine.

I also wanted to ask for the ability to mount /var/log as a volume from outside. Correct me, if I'm wrong - that would imply, that in /app/init we need to (re)create sub-directories with-in /var/log and set proper permissions on them.

from docker-redmine.

@elderone Its difficult to VOLUME mount /var/log. However I will make sure /var/log/redmine can be volume mounted.

from docker-redmine.

@b-a-t It would be a headache to handle volume mounting /var/log. re-creating required directories and correcting their permissions would be terrible.

from docker-redmine.

@b-a-t @elderone I will give it a shot though. From first glance looks like only /var/log/nginx, /var/log/supervisor and /var/log/redmine would need to be handled. I am not sure though.

from docker-redmine.

@sameersbn /var/log/redmine is very nice!
@b-a-t docker cp sameersbn/redmine:/var/log .

from docker-redmine.

I'm really new to docker(basically, only last week spent on making docker-redmine to fit my needs:)) so, possibly I'm not clear with what [VOLUME] does. What I want to be able to do is to launch application like:
docker run -v /var/log:/var/log ... and get redmine and related logs on the hosting server(or, in another container with elastic-search). From that prospective I'd expect /app/init just to be on a safe side to issue smth. like:
mkdir -p /var/log/redmine && chmod 0755 /var/log/redmine && chown redmine:redmine /var/log/redmine

And the same for nginx/ and supervisor/ with the exception that they should be happy with default root:root.

Again, I'm new to this, so maybe I'm missing some core obstacle.

While we are on permissions, I think, this should also be fixed:
drwxr-x--- 2 www-data adm 4096 Oct 16 22:54 /var/log/nginx
We start nginx as root and then setuid to redmine - at no step we are www-data. So, I'd suggest to chown redmine /var/log/nginx to be consistent. /var/lib/nginx seems to be OK already:

 ls -l /var/lib/nginx
total 20
drwx------ 2 redmine root 4096 Oct 16 22:54 body
drwx------ 2 redmine root 4096 Oct 16 22:54 fastcgi
drwx------ 2 redmine root 4096 Oct 16 22:54 proxy
drwx------ 2 redmine root 4096 Oct 16 22:54 scgi
drwx------ 2 redmine root 4096 Oct 16 22:54 uwsgi

Not sure, maybe dpkg-statoverride --add redmine adm 0750 /var/log/nginx before adding nginx would be better idea..

@b-a-t @elderone

I am thinking of collecting all the logs in /var/log/redmine. The following logs are of interest to us:

redmine:

• production.log
• unicorn.stdout.log
• unicorn.stderr.log

nginx:

• redmine_access.log
• redmine_error.log

supervisor:

• cron.log
• nginx.log
• supervisord.log
• unicorn.log

I intend to collect these at the following subdirs

• /var/log/redmine/redmine
• /var/log/redmine/nginx
• /var/log/redmine/supervisor

The user will be able to volume mount the /var/log/redmine/ directory.

Using this scheme we can create a data container for all the redmine logs,

docker run -it --name=redmine-logs_data \
-v /opt/redmine/logs:/var/log/redmine \
busybox true

And then import the logs volume into the redmine container like so,

docker run -it --name redmine [options] \
--volumes-from=redmine-logs_data \
sameersbn/redmine:latest

Now if you wanted to pump out these logs to logstash, all you would need to do is import the logs volume into your logstash container.

great! thank you!

from docker-redmine.

Thanks a lot, seems to work fine!

from docker-redmine.

Sorry for bothering you with this one again. I've just noticed, that supervisord.log still remains in /var/log/supervisor. Can you, please, also move it into /var/log/redmine/supervisor?

Also access.log and error.log remain in /var/log/nginx. Not sure, how useful they are, but for consistency...

from docker-redmine.

@b-a-t I did not think supervisord.log would be of any use. But no problem, I will move it.

The nginx access.log and error.log will always be empty, you will never have any logs in them.

from docker-redmine.

@sameersbn Thanks a lot! supervisord.log is handy, when trying to figure out why something goes wrong. Was helpful to me, when nginx didn't start due not expanded REDMINE_HTTPS_HSTS_MAXAGE.

from docker-redmine.

@b-a-t supervisord.log and the nginx access and error logs have now been moved to the logs volume.
