Docker container for Observium Community Edition

Observium is network monitoring with intuition. It is a low-maintenance auto-discovering network monitoring platform supporting a wide range of device types, platforms and operating systems including Cisco, Windows, Linux, HP, Juniper, Dell, FreeBSD, Brocade, Netscaler, NetApp and many more. Observium focuses on providing a beautiful and powerful yet simple and intuitive interface to the health and status of your network. For more information, go to http://www.observium.org site.

Available platform are:-

• AMD64 (Intel x86_64) https://hub.docker.com/r/mbixtech/observium/
• ARM32v7 (Raspberri Pi 2/3) https://hub.docker.com/r/mbixtech/arm32v7-observium/

Usage

Either follow the choice A. or B. below to run Observium.

A. Manual Run Containers

• Prepare working directory for docker containers, for example below.

  $ mkdir -p /home/docker/observium/{data,logs,rrd}

• Run official MariaDB container

  $ docker run --name observiumdb \
    -v /home/docker/observium/data:/var/lib/mysql \
    -e MYSQL_ROOT_PASSWORD=passw0rd \
    -e MYSQL_USER=observium \
    -e MYSQL_PASSWORD=passw0rd \
    -e MYSQL_DATABASE=observium \
    -e TZ=$(cat /etc/timezone) \
    mariadb

• Run this Observium container

  $ docker run --name observiumapp --link observiumdb:observiumdb \
    -v /home/docker/observium/logs:/opt/observium/logs \
    -v /home/docker/observium/rrd:/opt/observium/rrd \
    -e OBSERVIUM_ADMIN_USER=admin \
    -e OBSERVIUM_ADMIN_PASS=passw0rd \
    -e OBSERVIUM_DB_HOST=observiumdb \
    -e OBSERVIUM_DB_USER=observium \
    -e OBSERVIUM_DB_PASS=passw0rd \
    -e OBSERVIUM_DB_NAME=observium \
    -e OBSERVIUM_BASE_URL=http://yourserver.yourdomain:8080 \
    -e TZ=Asia/Bangkok
    -p 8080:80
    mbixtech/observium

Note:

• You must replace passwords specified in environment parameters of both containers with your secure passwords instead.
• OBSERVIUM_BASE_URL supports AMD64 container only (plan to support ARM32v7 soon).

B. Use Docker Composer

• Follow instuctions below to create extra working directory of docker containers (You can change /home/docker directory to your desired directory).

  $ cd /home/docker
  $ git clone https://github.com/somsakc/docker-observium.git observium
  $ cd observium
  $ mkdir data logs mysql

Note: You do not need to clone whole git repository. You can download docker-compose.yml file and .env file file. Then, place both files into e.g. /home/docker/observium directory mentioned above.

• Change some environments to your appropreate values in docker-compose.yml file, e.g. OBSERVIUM_ADMIN_USER, OBSERVIUM_ADMIN_PASS.

• Force pulling the latest observium image from docker hub web site. It is to ensure that you will get the latest one.

  $ docker-compose pull

• Run both database and observium containers.

  $ docker-compose up

• For your first time, you may add a new device, discover and poll that device. It is given an idea below (I follow https://docs.observium.org/install_debian/#perform-initial-discovery-and-poll).

  $ docker-compose exec app /opt/observium/add_device.php <hostname> <community> v2c
  $ docker-compose exec app /opt/observium/discovery.php -h all
  $ docker-compose exec app /opt/observium/poller.php -h all

TODOs

I have a lot of plan to enhance this project. However, my work is priority to focus first. I hope I will have more time to do it.

• Enhance more on Kubernetes platform, for both AMD64 and ARM64 (Pi).
• Enhance more with secure TLS to Observium GUI.
• Secure more container image.
