Hello,

 

I really dig the Obseron interface and will consider the new community edition to replace my current solution. In order to ease deployment in a "homelab" context and testing in general, an official Docker image (https://hub.docker.com/) would be greatly appreciated !

 

Thank you very much !

  Hey Romain,

  Thanks for the feedback!

  We do not have any plans yet on releasing an Docker image, our priorities at the moment are in developing new and improving old features. We'll put this on the new ideas list though.

  Romain,

  Here's what I've got so far. I haven't got the persistent storage setup yet, but it does work.

  There are two stages to building the final container. Here are my two Dockerfiles:

  Dockerfile 1. Build CentOS 7 with systemd - Per https://hub.docker.com/_/centos?tab=description

  FROM centos:7
  ENV container docker
  RUN (cd /lib/systemd/system/sysinit.target.wants/; for i in *; do [ $i == \
  systemd-tmpfiles-setup.service ] || rm -f $i; done); \
  rm -f /lib/systemd/system/multi-user.target.wants/*;\
  rm -f /etc/systemd/system/*.wants/*;\
  rm -f /lib/systemd/system/local-fs.target.wants/*; \
  rm -f /lib/systemd/system/sockets.target.wants/*udev*; \
  rm -f /lib/systemd/system/sockets.target.wants/*initctl*; \
  rm -f /lib/systemd/system/basic.target.wants/*;\
  rm -f /lib/systemd/system/anaconda.target.wants/*;
  VOLUME [ "/sys/fs/cgroup" ]
  CMD ["/usr/sbin/init"]

   

  Dockerfile 2. Build the Obseron container (without persistent storage):

  FROM centos7-systemd

  MAINTAINER robin@enegren.com

  RUN useradd obseron

  RUN rpm -Uvh http://packages.ksenos.fi/centos/7/x86_64/ksenos-release-0.1-3.noarch.rpm
  RUN yum -y upgrade && yum -y install obseron-daemon lm_sensors epel-release wget && yum -y install smartmontools && yum clean all
  RUN wget http://share.ksenos.fi/webmin-ksenos-1.820-1.noarch.rpm && yum -y localinstall webmin-ksenos-1.820-1.noarch.rpm && rm -rf ./webmin-ksenos-1.820-1.noarch.rpm

  RUN chkconfig webmin off && sed -i "s/^# chkconfig: 235 99 10$/# chkconfig: 235 84 10/g" /etc/init.d/webmin && chkconfig webmin on

  RUN echo obseron soft nofile 10000 >> "/etc/security/limits.conf" && echo obseron hard nofile 10000 >> "/etc/security/limits.conf"

  RUN mkdir -p /var/lib/obseron/{d,e} && chown -R obseron:obseron /var/lib/obseron

  EXPOSE 22 80 443 9191 8554 2525

  Forgot to mention that you need to run CentOS systemd containers with a few added options:

  On Debian-based hosts: sudo docker run -td -v /sys/fs/cgroup:/sys/fs/cgroup:ro -v /tmp/$(mktemp -d):/run -p 8888:80 obseron-test

  On Red Hat-based hosts: sudo docker run -td -v /sys/fs/cgroup:/sys/fs/cgroup:ro -p 8888:80 obseron-test

  (Also on https://hub.docker.com/_/centos?tab=description )
