Commit messages ^^^^^^^^^^^^^^^

Commit message formatting is significant!!

Please see How to contribute <https://github.com/saltstack-formulas/.github/blob/master/CONTRIBUTING.rst>_ for more details.

pre-commit ^^^^^^^^^^

pre-commit <https://pre-commit.com/> 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 <https://pre-commit.com/#installation>, 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

Special notes

The formula targets Debian and RedHat families. For OpenStack CLI (OSC) suppport, study the pillar.example carefully and raise an issue to track failed OSC commands.

Salt states (top.sls) for UBUNTU/CENTOS::

    base:
      '*':
        - devstack

Salt states (top.sls) for CLI::

    base:
      '*':
        - devstack.cli      #See https://docs.openstack.org/python-openstackclient/queens/cli/

Site/Release-specific Pillar Data::

    See `pillar.example`

The Devstack installer makes drastic and dramatic changes to your Linux environment. Use a fresh Linux OS installation and avoid making assumptions - Devstack only supports MYSQL on 127.0.0.1:

Available states

.. contents:: :local:

devstack ^^^^^^^^^^^^

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

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

devstack.user

Ensure stack user and group exists; included by devstack.install state.

devstack.install

Deploy devstack using stack.sh and custom localrc generated from pillar data.

devstack.clean

Remove devstack - run unstack, clean, remove users and directories.

devstack.user.clean

Ensure stack user and group is absent; included by devstack.clean state.

devstack.cli.create

Support for OSC create use cases. See https://docs.openstack.org/python-openstackclient/rocky/cli/command-list.html#command-list.

devstack.cli.delete

Support for OSC delete use cases. See https://docs.openstack.org/python-openstackclient/rocky/cli/command-list.html#command-list.

devstack.cli.set

Support for OSC set use cases. See https://docs.openstack.org/python-openstackclient/rocky/cli/command-list.html#command-list.

devstack.cli.add

Support for OSC add use cases. See https://docs.openstack.org/python-openstackclient/rocky/cli/command-list.html#command-list.

Testing

Linux testing is done with kitchen-salt.

Requirements ^^^^^^^^^^^^

.. code-block:: bash

$ 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 devstack 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.
