These are the Mojo specs for running deployments of Openstack. For more information on installing and running Mojo see lp:mojo

This branch contains the following top level assets:

• specs directory contains the specs themselves.
• SPEC_SUMMARY.txt contains descriptions of each spec
• Makefile has targets for checking lint and generating SPEC_SUMMARY.txt
• helper directory contains scripts and libraries used by the specs

The specs fall into the following catagories:

• dev: Specs which are still under development (these are not lint checked)
• full_stack: These perform a full openstack deployment
• bugs: Specs that reproduce a bug. These are useful for verifying a bugs existence and then once the fix has landed they can be used to verify a regression has not occured.
• features: These do a minimal deployment to demonstrate a new feature.
• object_storage: Specs for deploying a standalone object storage environment

The tip directory should be used to differentiate between Openstack versions.

specs/full_stack/charmhelper_upgrade/juno/

This spec is used to do a deployment of a full Juno Openstack environment and to test an upgrade of charmhelpers

The helper directory contains the following:

• bundles: Juju deployer bundles
• collect: Mojo collect and repo files, used to collect branches prior to running Juju Deployer
• scripts: Scripts for running lint checks etc
• setup: Manipulate the overcloud or provider
• template: An example spec
• tests: Tests to run against the deployment
• utils: Core set of utilities used by tests and setup

Directives: collect and repo

These specs collect the charm branches as a seperate step from deploying the charms. Although Juju deployer can do the branch collection, having this done as a seperate phase has a few advantages. It allows for the branches to be manipulated prior to deployment, the charmhelper upgrade spec does exactly this to check that a charmhelper sync will not break a deployment. It also allows for an alternative branch location for a given charm to be clearly specified, this is particulalry useful when an unmerged branch needs testing.

Directives: deploy

Mojo uses juju deployer to do the charm deployment. When specifying the target to use in the bundle the ${MOJO_SERIES} environment variable should be used in place of the Ubuntu release version. This allows the same spec to be used for deployments on different Ubuntu release.

deploy config=haphase1.yaml delay=0 target=${MOJO_SERIES}-juno

Directives: script

There are a number of helper scripts used to setup the cloud once it has been deployed. In general they consist of the script to do the setup and a YAML file of options.

• image_setup.py: This script downloads guest images and uploads them to Glance. images.yaml lists the images to be downloaded and information about those images.
• keystone_setup.py: Setup keystone users and roles. keystone_users.yaml lists the users to be created and what roles they should be given
• network_setup.py: This sets up the SDN on the cloud. network.yaml describes the SDN topology

Directives: verify

There are a number of tests to choose from, some are specific to particular bugs or features. However, the main tests used to verify the cloud are:

• simple_os_checks.py: This script creates guests on the cloud, associates floating ips and then uses ssh to connect to the cloud and verifies its hostname. This ensure that the guest got a network and metadata on boot.
• test_obj_store.py: This script fires two streams of objects and the object store and retireves them
• tempest.py: This doesn't actually exist in any real sense but will do rsn!

Directives: script

There are scripts for manipulating the cloud, usually at the Juju level. These include:

• add_unit.py: Use juju to add a unit to a given service
• chaos_pony.py: Kill, test and add units to all services
• delete_crm_leader.py: Delete the unit Corosync reports is the leader for a given service
• delete_router_home.py: Delete the unit housing a particular Neutron router
• delete_unit.py: Delete a given unit
• juju_set.py: Juju set a kv pair for a given service
• upgrade_all_services.py: Perform a Juju charm upgrade on all services
• upgrade_services.py: Perform a Juju charm upgrade on a given service

There are two helper libraries in helper/utils/.

• mojo_os_utils.py: Functions for manipulating the deployed Openstack cloud.
• mojo_utils.py: Functions for manipulating the providor environment. Juju add/remove unit etc
