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.

chef-zipkin Cookbook

This cookbook installs and configures the Zipkin distributed tracing system.

Requirements

Chef 12+

Platforms

This cookbook uses Test Kitchen to do cross-platform convergence and post-convergence tests. The tested platforms are considered supported. This cookbook may work on other platforms or platform versions with or without modification.

  • Ubuntu 12.04, 14.04

Note that Upstart is the only supported init system currently.

Cookbooks

This cookbook does not depend on any other cookbooks but Java is required to to run Zipkin. Therefore, the java cookbook is recommended.

Attributes

Attributes have default values set in attributes/default.rb. Configuration for the various Zipkin components (collector, storage, etc.) is done entirely via environment variables. In an effort to support a flexible configuration pattern the node['zipkin']['env_vars'] hash is provided. Configuration key-value pairs should be placed in here and they will be exported as environment variables in the startup script. This hash is intended to be one level deep and the keys will be uppercased and exported.

For instance, given the following attribute configuration: default['zipkin']['env_vars']['query_port'] = 8080 default['zipkin']['env_vars']['storage_type'] = 'mysql' default['zipkin']['env_vars']['mysql_user'] = 'buster' default['zipkin']['env_vars']['mysql_pass'] = 'motherboy' default['zipkin']['env_vars']['mysql_use_ssl'] = true default['zipkin']['env_vars']['zipkin_ui_environment'] = 'qa'

Will produce the following values in the init script: export QUERY_PORT="8080" export STORAGE_TYPE="mysql" export MYSQL_USER="buster" export MYSQL_PASS="motherboy" export MYSQL_USE_SSL="true" export ZIPKIN_UI_ENVIRONMENT="qa"

General attributes:

  • node['zipkin']['version']: Version to install.
  • node['zipkin']['install_dir']: Where to install the application. Defaults to /opt/zipkin.
  • node['zipkin']['manage_user']: Should we create the user and group?
  • node['zipkin']['user']: User to run the daemon as. Defaults to zipkin.
  • node['zipkin']['group']: Group to run the daemon as. Defaults to zipkin.
  • node['zipkin']['uid']: User ID for the Zipkin user.
  • node['zipkin']['gid']: Group ID for the Zipkin group.
