Supermarket Belongs to the Community

Supermarket belongs to the community. While Chef has the responsibility to keep it running and be stewards of its functionality, what it does and how it works is driven by the community. The chef/supermarket repository will continue to be where development of the Supermarket application takes place.

dataloop_chef_client

Build Status Project Status

This cookbook provides a dataloop plugin that monitors the last check-in time from chef clients. Please note that it does not install dataloop. It does, however, expect that dataloop is installed in order for its file-based plugin deployment to work properly.

Deployment

Simply add dataloop_chef_client the run-list. It will deploy a three resources:

  • script: Executable file responsible for querying the ChefSever for the ohai_time and writing plugin output to file (/var/opt/dataloop_chef_client.out by default)
  • plugin: Executable file resopnsible for reading the contents of the output file to be interpreted by dataloop, stored by default in /opt/dataloop/plugins
  • cron: Executes the script on a given interval

Important attributes:

  • default['dataloop-chef-client']['warning']: default 3600 seconds (1 hour)
  • default['dataloop-chef-client']['critical']: default 86400 (1 day)

Tested Operating Systems

  • Ubuntu 12.04
  • Ubuntu 14.04
  • Centos 6.7
  • Centos 7.2

Tested Chef Clients

  • 11.18.0

Development

Be sure to have a docker instance running. docker-machine is a good way to ensure this. Installation instructions can be found here

Next, execute the following in the root of this project:

docker-machine start
eval $(docker-machine env)
gem install bundler
bundle install

If all is well, you should have all dependencies installed. To test, simply run rake. Integration tests are run under test-kitchen using the kitchen-docker provider.

Why a leverage a cron job?

The Chef-API needs read access to sensitive files, namely client.rb and client.pem. Instead of granting the dataloop user access to these files, this cookbook run the script under root and simply allows the dataloop user to read the output of the script.
