Fully automated and managed Chef server

Primary LanguageRubyApache License 2.0Apache-2.0

managed-chef-server

Deploys and configures the Chef server in a relatively stateless model. The included policyfiles provide examples of deployment options and the required attributes.

Recipes

default

Install or restore the Chef Server in a new deployment, wrapping the Chef-Server cookbook. It looks for the existence of a knife-ec-backup tarball to restore from, configured with the node['mcs']['restore']['file'] attribute. You will need to use the managed_organization recipe or provide your own organizations recipe to use the other recipes.

managed_organization

This creates a managed Chef organization and an org-managing admin user through the appropriate attributes.

backup

Runs knife ec backup via cron and puts the backups in the node['mcs']['backup']['dir']. The default is 2:30am daily, but you may change the cron schedule via the following attributes.

node['mcs']['backup']['cron']['minute'] = '30'
node['mcs']['backup']['cron']['hour'] = '2'
node['mcs']['backup']['cron']['day'] = '*'
node['mcs']['backup']['cron']['month'] = '*'
node['mcs']['backup']['cron']['weekday'] = '*'

cron

Schedules the Chef client to run on the Chef server via cron against a provided policyfile archive. This may be set to use --local-mode, for when the Chef client has no other Chef server to contact. See the example policyfiles/cron.rb and kitchen.yml for reference.

data_bag_loader

The node['mcs']['data_bags']['dir'] is compared against the existing data bags on the server and creates and/or updates them as necessary. If the node['mcs']['data_bags']['prune'] attribute is true then the data bags and their items are deleted if they exist on the server but do not have the requisite JSON files.

legacy_loader

Takes the node['mcs']['cookbooks']['dir'], node['mcs']['environments']['dir'] and node['mcs']['roles']['dir'] directories and loads whatever content is found into the Chef server organization. If you want to use the same directory for the roles and environments the recipe can distinguish between JSON files. The cookbooks are expected to be tarballs in a directory, they will all be attempted to load via their Berksfile or with knife. For legacy cookbooks with multiple dependencies it may take multiple runs to load everything.

policyfile_loader

Takes the node['mcs']['policyfile']['dir'] and parses any .lock.json files to determine which policyfile archives to load into the local Chef server. Policies will be assigned to the group designated by the node['mcs']['policyfile']['group'] attribute for the Chef server (_default is the default). If the policy itself sets the node['mcs']['policyfile']['group'] attribute, the policy will be assigned to that group.

Attributes

The default.rb attributes file documents available settings and tunings.

Custom Resources

Custom resources are used to reduce the complexity of the included recipes.

managed_organization

The :create action will instantiate a Chef server organization with an internal administrator user. The name properties is the organization. The organization's full_name, email, and password are all optional properties.

managed_chef_server_backup

This resource schedules backups of the Chef server via cron-style properties (minute, hour, day, month, weekday). The backups are written to the directory and their filenames start with the prefix.

managed_chef_server_cron

This resource requires an archive property specifying the policyfile archive to deploy and use for running via cron.

managed_chef_server_restore

This resource requires a tarball property specifying the knife ec backup tarball to restore from.

cookbook_loader

This resource runs berks or knife against the directory property specifying the source for the cookbook tarballs to keep in sync with the server.

data_bag_loader

This resource works off of the directory property specifying the source for the data bags to keep in sync with the server.

managed_data_bag

This has :create, :prune, :item_create, and :item_prune for managing the data bags available on the server. This custom resource is called from the data_bag_loader resource.

environments_loader

All of the Ruby or JSON environment files in the directory will be loaded onto the Chef Server and updated if they change.

policyfile_loader

This resource looks for policyfile locks and archives in the directory specifying the source, only uploading them if they have been updated.

roles_loader

All of the Ruby or JSON role files in the directory will be loaded onto the Chef Server and updated if they change.

Testing

There is a kitchen.yml that may be used for testing with Vagrant. The kitchen.vagrant.yml may be symlinked as kitchen.local.yml and used with local caches to speed up testing. If you want to use Docker, kitchen.dokken.yml may be used but it does not persist changes between runs and is thus not significantly faster (it's slower than Vagrant with caching). The following Suites map to example policyfiles that may be repurposed as necessary, with variants for testing Chef 14 and 15 of each:

default

Tests simple installation and creation of the managed Chef user and organization.

restore

Restores the Chef server from a backup with policyfiles. kitchen verify restore ensures the policyfiles were restored properly.

cron

Checks the chef-client is in the crontab

backup

Checks the backup script is in the crontab and backup directories are available.

data_bags

Adds loading data bags from the included test directory. It restores from a previous data bag backup to ensure pruning and updating work.

policyfile

Adds loading policyfiles from the included test directory.

legacy

Adds loading cookbooks, environments and roles from the included test directory.

everything

Installs the Chef server, restores from a backup, attempts to load policyfiles (which are included in the restored backup) and adds backup via cron.
