unbound-formula

A SaltStack formula which manages _unbound.

The actual configuration file is out of scope. It's not trivial to map Pillar data to ubound's configuration format. Furthermore it's not clear that this the best approach in all use-cases.

Therefore this formula assumes you'll provide a configuration file (or a template) following the TOFS pattern.

Commit messages

Commit message formatting is significant!!

Please see How to contribute for more details.

pre-commit

pre-commit is configured for this formula, which you may optionally use to ease the steps involved in submitting your changes. First install the pre-commit package manager using the appropriate method, then run bin/install-hooks and now pre-commit will run automatically on each git commit. :

$ bin/install-hooks
pre-commit installed at .git/hooks/pre-commit
pre-commit installed at .git/hooks/commit-msg

Available states

unbound

Meta-state (This is a state that includes other states).

This installs the unbound package, manages the unbound configuration file and then starts the associated unbound service.

unbound.package

This state will install the unbound package only.

unbound.config

This state will configure the unbound service and has a dependency on unbound.install via include list.

unbound.service

This state will start the unbound service and has a dependency on unbound.config via include list.

unbound.clean

Meta-state (This is a state that includes other states).

this state will undo everything performed in the unbound meta-state in reverse order, i.e. stops the service, removes the configuration file and then uninstalls the package.

unbound.service.clean

This state will stop the unbound service and disable it at boot time.

unbound.config.clean

This state will remove the configuration of the unbound service and has a dependency on unbound.service.clean via include list.

unbound.package.clean

This state will remove the unbound package and has a depency on unbound.config.clean via include list.

Testing

Linux testing is done with kitchen-salt.

Requirements

• Ruby
• Docker

$ gem install bundler
$ bundle install
$ bin/kitchen test [platform]

Where [platform] is the platform name defined in kitchen.yml, e.g. debian-9-2019-2-py3.

bin/kitchen converge

Creates the docker instance and runs the unbound main state, ready for testing.

bin/kitchen verify

Runs the inspec tests on the actual instance.

bin/kitchen destroy

Removes the docker instance.

bin/kitchen test

Runs all of the stages above in one go: i.e. destroy + converge + verify + destroy.

bin/kitchen login

Gives you SSH access to the instance for manual testing.
