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.

Installs RethinkDB and configures it in a cluster.

  • Chef >= 16


Server process

Name Purpose Default
default['rethinkdb']['version'] Choose the package version to be installed nil meaning latest
default['rethinkdb']['server_tags'] Tags to be passed when running the server. See the Server tags documentation page nil meaning no tags
default['rethinkdb']['data_directory'] Server directory where data and logs are stored /var/lib/rethinkdb/instances.d/cluster
default['rethinkdb']['tls']['cluster'] Should the cluster communication be secured using certificate from an encrypted data bag false


Name Purpose Default
default['rethinkdb']['network']['bind'] Address of local interfaces to listen on when accepting connections (See attributes/default.rb`) nil meaning RethinkDB default to all local addresses
default['rethinkdb']['network']['ports']['cluster'] RethinkDB port used for cluster communications nil meaning RethinkDB default to 29015 + port-offset


This cookbook leverages the Chef's search so that converging a first node will
initialize a RetinkDB cluster, while all other converged nodes, with the same
tags than the first one, will automatically join it automatically.

Securing cluster communications

When your nodes doesn't have a secured private network, you must secure the
cluster communications using a TLS certificate.\
You can find more on the RethinkDB documentation.

In order to do so, you have the create a TLS certificate following the
instructions from the RethinkDB documentation page.\
You should have a cert.pem and a 'key.pem' file.

You will have to store them inline so you need to get a single line version
usign the commands :
* awk 'NF {sub(/\r/, ""); printf "%s\\n",$0;}' cert.pem && echo
* awk 'NF {sub(/\r/, ""); printf "%s\\n",$0;}' key.pem && echo

Now you need to create an encrypted data bag with named rethinkdb with the
item tls:

EDITOR=nano knife data bag create rethinkdb tls --secret-file ~/.chef/knife-secret

(The file ~/.chef/knife-secret is a regular file including a simple string,
like a MD5, SHA256, RSA key etc). You have to upload that file on each nodes at
the path /etc/chef/encrypted_data_bag_secret which will allow Chef to decrypt
the data bag).

In the created data bag, add the cluster-cert and cluster-key attributes with
the inline version of the above generated files:

  "id": "tls",
  "cluster-cert": "-----BEGIN CERTIFICATE-----\nMIID...Uj4=\n-----END CERTIFICATE-----\n",
  "cluster-key": "-----BEGIN RSA PRIVATE KEY-----\nMIIE...hjU\n-----END RSA PRIVATE KEY-----\n"

Last but not least update the `default['rethinkdb']['tls']['cluster']` attribute
to `true` and converge.
