Beaker library to use openstack hypervisor

How to use this wizardry

This gem that allows you to use hosts with openstack hypervisor with beaker.

Beaker will automatically load the appropriate hypervisors for any given hosts file, so as long as your project dependencies are satisfied there's nothing else to do. No need to require this library in your tests.

With Beaker 3.x

This library is included as a dependency of Beaker 3.x versions, so there's nothing to do.

With Beaker 4.x

As of Beaker 4.0, all hypervisor and DSL extension libraries have been removed and are no longer dependencies. In order to use a specific hypervisor or DSL extension library in your project, you will need to include them alongside Beaker in your Gemfile or project.gemspec. E.g.

# Gemfile
gem 'beaker', '~>4.0'
gem 'beaker-aws'
# project.gemspec
s.add_runtime_dependency 'beaker', '~>4.0'
s.add_runtime_dependency 'beaker-aws'

Spec tests

Spec test live under the spec folder. There are the default rake task and therefore can run with a simple command:

bundle exec rake test:spec

Acceptance tests

We run beaker's base acceptance tests with this library to see if the hypervisor is working with beaker. Please check our openstack docs to create host file to run acceptance tests. You need to set two environment variables before running acceptance tests:

1. OPENSTACK_HOSTS - Path to hostfile with hosts using openstack hypervisor

2. OPENSTACK_KEY - Path to private key that is used to SSH into Openstack VMs

You will need at least two hosts defined in a nodeset file. An example comprehensive nodeset is below (note that not all parameters are required):

HOSTS:
  master:
    roles:
      - agent
      - master
      - dashboard
      - database
    hypervisor: openstack
    platform: <my_platform> 
    user: <host_username>
    image: <host_image>
    flavor: <host_flavor>
    ssh:
      user: cloud-user
      password: <cloud-user_password>
      auth_methods:
        - password
        - publickey
      keys:
        - <relative_path/public_key>
    user_data: |
      #cloud-config
      output: {all: '| tee -a /var/log/cloud-init-output.log'}
      disable_root: <True/False>
      ssh_pwauth: <True/False>
      chpasswd:
        list: |
           root:<root_password>
           cloud-user:<cloud-user_password>
        expire: False
      runcmd:
        - <my_optional_commands>

  agent_1:
    roles:
      - agent
      - default
    hypervisor: openstack
    platform: <my_platform>
    user: <host_username>
    image: <host_image>
    flavor: <host_flavor>
    ssh:
      user: cloud-user
      password: <cloud-user_password>
      auth_methods:
        - publickey
      keys:
        - <relative_path/public_key>
      number_of_password_prompts: 0
      keepalive: true
      keepalive_interval: 5
    user_data: |
      #cloud-config
      output: {all: '| tee -a /var/log/cloud-init-output.log'}
      disable_root: <True/False>
      ssh_pwauth: <True/False>
      chpasswd:
        list: |
           root:<root_password>
           cloud-user:<cloud-user_password>
        expire: False
      runcmd:
        - <my_optional_commands>

CONFIG:
  log_level: <trace/debug/verbose/info/notify/warn>
  trace_limit: 50
  timesync: <true/false>
  nfs_server: none
  consoleport: 443
  openstack_username: <insert_username>
  openstack_api_key: <insert_password>
#  openstack_project_name: <insert_project_name>     # alternatively use openstack_project_id
  openstack_project_id: <insert_id>
#  openstack_user_domain: <insert user_domain>       # alternatively use openstack_user_domain_id
  openstack_user_domain_id: <insert_id>
#  openstack_project_domain: <insert_project_domain> # alternatively use openstack_project_domain_id
  openstack_project_domain_id: <insert_id>
  openstack_auth_url: http://<keystone_ip>:5000/v3/
  openstack_network: <insert_network>
  openstack_keyname: <insert_key>
  openstack_floating_ip: <true/false>
  openstack_volume_support: <true/false>
  security_group: ['default']
  preserve_hosts: <always/onfail/onpass/never>
  create_in_parallel: true
  run_in_parallel: ['configure', 'install']
  type: <foss/git/pe>

Note that when using _id parameters, you must also match the parameter type across the following when domain is specified:

• openstack_project_id
• openstack_user_domain_id
• openstack_project_domain_id

Further, you can opt to use a static master by setting the master's hypervisor to none, and identifying its location thus:

    hypervisor: none
    hostname: <master_hostname>
    vmhostname: <master_hostname>
    ip: <master_ip>

Additionally, you can set instance creation to occur in parallel instead of sequentially via this CONFIG entry:

create_in_parallel: true

Additional parameter information is available at https://github.com/voxpupuli/beaker/blob/master/docs/concepts/argument_processing_and_precedence.md

There is a simple rake task to invoke acceptance test for the library once the two environment variables are set:

bundle exec rake test:acceptance
