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.

Chef cookbook to deploy SSL/TLS certificates (including root ones) on a system. Data is stored in the encrypted data bag which name is specified in the attribute node['tls']['data_bag_name'] (by default tls). Data bag item name matches node.chef_environment value.

Certificate files will be placed under the directory specified in attribute node['tls']['base_dir'] (by default /etc/chef-tls).

Root certificate files will be placed under system directories.

Certificate deployment is made by using tls_certificate resource. For example,

tls_certificate 'www.domain.tld' do
  action :deploy

Different software (e.g. Nginx, Postfix) will require paths to deployed certificates, private keys and SCTs. To obtain these paths, ::ChefCookbook::TLS helper should be used. Below is the example:

tls_item = 'www.domain.tld'

tls_item.certificate_path  # Get path to the certificate
tls_item.certificate_private_key_path  # Get path to the certificate's private key
tls_item.scts_dir  # Get path to the folder with deployed SCTs
tls_item.hpkp_pins  # Get array of HPKP pins


Installing/uninstalling CA certificates only works on Ubuntu systems.
To obtain path to CA certificate bundle, ::ChefCookbook::TLS helper should be used. Below is the example:

tls_helper =

tls_helper.ca_bundle_path  # Get CA certificate bundle path


tls_ca_certificate 'Custom_CA' do
  action :install


tls_ca_certificate 'Custom_CA' do
  action :uninstall
