CMK 2.0 - Docker | Nagios fails to start, restart loop

[bjerre (Simon Bjerre)]

Dear Forum.

I just pull’ed the docker image and started it up for the first time.
But its not loading in the browser witht he given url.

When i look at the logs, nagios fails to start, and the startup process is restarted and fails agian.

### CREATING SITE 'cmk'

Adding /opt/omd/sites/cmk/tmp to /etc/fstab.

Going to set TMPFS to off.

Temporary filesystem already mounted

Updating core configuration...

Generating configuration for core (type nagios)...Precompiling host checks...OK

OK

Created new site cmk with version 2.0.0p6.cre.


The site can be started with omd start cmk.

The default web UI is available at http://73cf19ce0994/cmk/


The admin user for the web applications is cmkadmin with password: QsSJNer4

For command line administration of the site, log in with 'omd su cmk'.

After logging in, you can change the password for cmkadmin with 'htpasswd etc/htpasswd cmkadmin'.


### STARTING XINETD

[....] Starting internet superserver: xinetde7[ ok e8.

### STARTING SITE

Temporary filesystem already mounted

Starting mkeventd...OK


Starting rrdcached...OK

Starting npcd...OK

Starting nagios.............ERROR

Starting apache...OK

Starting redis...OK

Any way do debug further?
Other images works fine

Can you share the command you use to start the docker container?
I just tried it with:

docker run -p8082:5000 --rm checkmk/check-mk-raw:2.0.0p6

and can access the webinterface for 2.0.0p6 (CRE)

have you already looked into /omd/sites/cmk/var/log inside the container?

[bjerre (Simon Bjerre)]

I accessed the cli and ran ‘omd status’ and the apache + nagios was not running.
Not able to view the logs as the docker restarts, with the last lines on the run command

docker container run -dit -p 8080:5000 --ulimit nofile=1024 --tmpfs /opt/omd/sites/cmk/tmp:uid=1000,gid=1000 -v monitoring:/omd/sites --name monitoring -v /etc/localtime:/etc/localtime:ro --restart always checkmk/check-mk-raw:2.0.0-latest

Will have a try without the restart bit
