This repository contains Dockerfile for automated builds of:

• Shinken: https://registry.hub.docker.com/u/rohit01/shinken/

• shinken Thruk Graphite: https://registry.hub.docker.com/u/rohit01/shinken_thruk_graphite/

Get started in 3 easy steps:

1. Install docker. Select and pull one of the following docker image:

   • Shinken: It has basic shinken installation along with few must have modules like WebUI (Web Interface), standard nrpe plugins + few extra ones, nrpe-booster support and a lightweight web server (nginx). Link: https://registry.hub.docker.com/u/rohit01/shinken/
   • Shinken Thruk: Shinken (as written above) + Thruk web interface. Internal web server nginx is replaced with apache2. Link: https://registry.hub.docker.com/u/rohit01/shinken_thruk/
   • Shinken Thruk Graphite: Shinken Thruk (as written above) + graph support in WebUI. Graphs are stored and served using graphite. Retention is configured for 1 month on a per 2 minute basis. Link: https://registry.hub.docker.com/u/rohit01/shinken_thruk_graphite/

   Sample Command: $ sudo docker pull rohit01/shinken

2. Clone this project. There are three directories corresponding to the docker images mentioned above. Go inside the directory corresponding to your selected image. You will see a directory named: custom_configs/. Keep all your configuration files here. A default configuration for monitoring docker host is already defined. User login details can be updated in this file: htpasswd.users. File contains the documentation in comments.

3. Run the docker image. Expose TCP port 80 to the base machine and mount custom_configs directory to /etc/shinken/custom_configs. Sample execution:

   $ git clone https://github.com/rohit01/docker_shinken.git
   $ cd docker_shinken/shinken_basic
   $ sudo docker run -d -v "$(pwd)/custom_configs:/etc/shinken/custom_configs" -p 80:80 rohit01/shinken
   

Open your browser and visit these urls (Default credential - admin/admin):

1. WebUI: http://localhost/. Available on all three images.
2. Thruk UI: http://localhost/thruk/. Available on shinken_thruk and shinken_thruk_graphite images.
3. Graphs: http://localhost/service/docker_shinken/http_port_7770#graphs. Available only on shinken_thruk_graphite image.

Please Note:

• Configuration changes are required only in one place/directory: custom_configs
• The nrpe plugins installation directory is /usr/lib/nagios/plugins.
• If you are using custom NRPE plugins, please mount your plugins directory inside docker container at /usr/local/custom_plugins. You need to define resource paths accordingly.
