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. Come be part of shaping the direction of Supermarket by opening issues and pull requests or by joining us on the Chef Mailing List.

useful datastructures

  • databases json { "stack_commons": { "mysql": { "example_db": { "user": "exampleuser", "password": "do_not_use_this_password" } } } }

stack_commons

  • MySQL DB Single Node: json { "run_list": [ "recipe[platformstack::default]", "recipe[platformstack::rackops_rolebook]", "recipe[stack_commons::mysql_base]" ] }

  • MySQL DB Master Node: json { "run_list": [ "recipe[platformstack::default]", "recipe[platformstack::rackops_rolebook]", "recipe[stack_commons::mysql_master]" ] }

  • MySQL DB Slave Node: json { "run_list": [ "recipe[platformstack::default]", "recipe[platformstack::rackops_rolebook]", "recipe[stack_commons::mysql_slave]" ] }

  • PostgreSQL clustering

Ensure the following attributes are set within environment or wrapper cookbook

node['postgresql']['version'] = '9.3'
node['postgresql']['password'] = 'postgresdefault'
node['pg-multi']['replication']['password'] = 'useagudpasswd'
node['pg-multi']['master_ip'] = '1.2.3.4'
node['pg-multi']['slave_ip'] = ['5.6.7.8']

# Depending on OS one of the following two must be set:
node['postgresql']['enable_pdgd_yum'] = true  # (Redhat Family)
node['postgresql']['enable_pdgd_apt'] = true  # (Debian Family)
  • Master PostgreSQL node: json { "run_list": [ "recipe[platformstack::default]", "recipe[platformstack::rackops_rolebook]", "recipe[stack_commons::postgresql_master]" ] }

  • Slave PostgreSQL node: json { "run_list": [ "recipe[platformstack::default]", "recipe[platformstack::rackops_rolebook]", "recipe[stack_commons::postgresql_slave]" ] }

Other Notes

New Relic Monitoring

To configure New Relic, make sure the node['newrelic']['license'] attribute is set and include the platformstack cookbook in your run_list. You can also run the stack_commons::newrelic recipe for some more advanced monitors.

Monitoring

Monitoring is set up only when platformstack is present. See platformstack's README.md and attribute file on monitors.

New Relic Plugins

Due to a resource name conflict between elasticsearch and newrelic_plugins cookbook we are using a fork rather than the upstream cookbook. You need to get this fork or add the following lines to your Berkshelf file :

cookbook 'newrelic_plugins', git: 'git@github.com:rackspace-cookbooks/newrelic_plugins_chef.git'

More details : https://github.com/newrelic-platform/newrelic_plugins_chef/pull/29
