OpenStack

kitchen-openstack is a Test Kitchen driver for OpenStack.

Minimum Configuration

driver:
  name: openstack
  openstack_username: [YOUR OPENSTACK USERNAME]
  openstack_api_key: [YOUR OPENSTACK API KEY] # AKA your OpenStack Password
  openstack_auth_url: [YOUR OPENSTACK AUTH URL] # if you are using v3, API_URL/v3/auth/tokens
  openstack_domain_id: [default is 'default'; otherwise YOUR OPENSTACK DOMAIN ID]
  image_ref: [SERVER IMAGE ID]
  flavor_ref: [SERVER FLAVOR ID]
transport:
  username: ubuntu # For a Ubuntu Box

The image_ref and flavor_ref options can be specified as an exact id, an exact name, or as a regular expression matching the name of the image or flavor.

All of Fog’s openstack options (openstack_domain_name, openstack_project_name, …) are supported. This includes support for the OpenStack Identity v3 API.

General Configuration

name

Required Tell test-kitchen what driver to use. ;)

openstack_username

Required Your OpenStack username.

openstack_api_key

Required Your OpenStack API Key, aka your OpenStack password.

openstack_auth_url

Required Your OpenStack auth url. If you are using ID v3, you’ll need to use API_URL/v3/auth/tokens.

require_chef_omnibus

Required Set to true otherwise the specific version of Chef omnibus you want installed.

image_ref

image_ref or image_id required Server Image Name or ID.

image_id

image_ref or image_id required Server Image ID. Specifying the ID instead of reference results in a faster create time.

Note If the image UUID changes this value will need to be updated.

flavor_ref

flavor_ref or flavor_id required Server Flavor Name or ID.

flavor_id

flavor_ref or flavor_id required Specifying the ID instead of reference results in a faster create time.

Note If the flavor UUID changes this value will need to be updated.

server_name

If a server_name_prefix is specified then this prefix will be used when generating random names of the form <NAME PREFIX>-<RANDOM STRING> e.g. myproject-asdfghjk. If both server_name_prefix and server_name are specified then the server_name takes precedence.

server_name_prefix

If you want to have a static prefix for a random server name.

port

Set the SSH port for the remote access.

openstack_tenant

Your OpenStack tenant id.

openstack_region

Your OpenStack region id.

availability_zone

Your OpenStack availability zone.

openstack_service_name

Your OpenStack compute service name.

openstack_network_name

Your OpenStack network name used to connect to, if you have only private network connections you want declare this.

glance_cache_wait_timeout

When OpenStack downloads the image into cache, it takes extra time to provision. Timeout controls maximum amount of time to wait for machine to move from the Build/Spawn phase to Active.

connect_timeout

Connect timeout controls maximum amount of time to wait for machine to respond to ssh login request.

read_timeout

write_timeout

Expose read/write timeout parameters passed down to HTTP connection created via excon. Default timeouts (from excon) are 60 seconds.

server_wait

server_wait is a workaround to deal with how some VMs with cloud-init. Some clouds need this some, most OpenStack instances don’t. This is a stop gap wait makes sure that the machine is in a good state to work with. Ideally the transport layer in Test-Kitchen will have a more intelligent way to deal with this. There will be a dot that appears every 10 seconds as the timer counts down. You may want to add this for WinRM instances due to the multiple restarts that happen on creation and boot. A good default is 300 seconds to make sure it’s in a good state.

The default is 0.

security_groups

A list of security_groups to join:

security_groups:
   - [A LIST OF...]
   - [...SECURITY GROUPS TO JOIN]

user_data

If your VMs have cloud-init enabled you can use the user_data in your kitchen.yml to inject commands at boot time.

    driver_config:
      user_data: userdata.txt

Then create a userdata.txt in the same directory as your .kitchen.yml, for example:

#!/bin/sh
echo "do whatever you want to pre-configure your machine"

cloud_config

If your VMs have cloud-init enabled you can use cloud_config to generate userdata for use by cloud-init in the cloud-config format. This provides a convenient way to specify cloud-init config inline. As the cloud-config format uses YAML the resulting userdata is essentially a copy+paste of cloud_config with the header line ‘#cloud-config’

    driver_config:
      cloud_config:
        hostname: my-hostname

This will pass the following user data to OpenStack:

#cloud-config
hostname: my-hostname

The cloud_config and user_data options are mutually exclusive.

config_drive

If your VMs require config drive.

    config_drive: true

network_ref

Deprecated A list of network names to create instances with.

network_ref:
   - [OPENSTACK NETWORK NAMES]
   - [CREATE INSTANCE WITH]

network_id

A list of network ids to create instances with. Specifying the id instead of reference results in a faster create time.

Note If the network UUID changes this value will need to be updated.

network_ref:
   - [OPENSTACK NETWORK UUIDs]
   - [TO CREATE INSTANCE WITH]

no_ssh_tcp_check

Deprecated You should be using transport now. This will skip the ssh check to automatically connect.

The default is false.

no_ssh_tcp_check_sleep

Deprecated You should be using transport now. This will sleep for so many seconds. no_ssh_tcp_check needs to be set to true.

private_key_path

Deprecated You should be using transport now. The guest image should use cloud-init or some other method to fetch key from meta-data service.

public_key_path

Deprecated You should be using transport now. The guest image should use cloud-init or some other method to fetch key from meta-data service.

Disk Configuration

block_device_mapping

make_volume

Makes a new volume when set to true.

The default is false.

snapshot_id

When set, will make a volume from that snapshot id.

volume_id

When set, will attach the volume id.

device_name

Set this to vda unless you really know what you are doing.

availability_zone

The block storage availability zone.

The default is nova.

volume_type

The volume type, this is optional.

delete_on_termination

This will delete the volume on the instance when destroy happens, if set to true. Otherwise set this to false.

creation_timeout

Timeout to wait for volume to become available. If a large volume is provisioned, it might take time to provision it on the backend. Maximum amount of time to wait for volume to be created and be available.

attach_timeout

If using a customized version of Openstack such a VMWare Integrated OPenstack (VIO), it may mark a volume active even though it is still performing some actions which may cause test kitchen to attach the volume to early which results in errors. Specify in seconds the amount of time to delay attaching the volume after its been marked active. Default timeout is 0.

Example

block_device_mapping:
  make_volume: true
  snapshot_id: 00000-111111-0000222-000
  device_name: vda
  availability_zone: nova
  delete_on_termination: false
  creation_timeout: 120
  attach_timeout: 240

Network and Communication Configuration

floating_ip

A specific floating_ip can be provided to bind a floating IP to the node. Any floating IP will be the IP used for Test Kitchen’s Remote calls to the node.

floating_ip_pool

A floating_ip_pool can be provided to allocate a floating IP from the pool to the instance. If allocate_floating_ip is true, the IP will be allocated, otherwise the first free floating IP will be used. It will be the IP used for Test Kitchen’s Remote calls to the node. If allocated, the floating IP will be released once the instance is destroyed.

allocate_floating_ip

If true, allocate a new IP from the specified floating_ip_pool and release is afterwards. Otherwise, if false (the default), an existing allocated IP.

[public|private]_ip_order

In some complex network scenarios you can have several IP addresses designated as public or private. Use public_ip_order or private_ip_order to control which one to use for further SSH connection. Default is 0 (first one)

For example if you have openstack istance that has network with several IPs assigned like

+--------------------------------------+------------+--------+------------+-------------+----------------------------------+
| ID                                   | Name       | Status | Task State | Power State | Networks                         |
+--------------------------------------+------------+--------+------------+-------------+----------------------------------+
| 31c98de4-026f-4d12-b03f-a8a35c6e730b | kitchen    | ACTIVE | None       | Running     | test=10.0.0.1, 10.0.1.1   |

to use second 10.0.1.1 IP address you need to specify

  private_ip_order: 1

assuming that test network is configured as private.

use_ipv6

If true use IPv6 addresses to for SSH connections. If false, the default, use IPv4 addresses for SSH connections.

network_ref

The network_ref option can be specified as an exact id, an exact name, or as a regular expression matching the name of the network. You can pass one

  network_ref: MYNET1

or many networks

network_ref:
  - MYNET1
  - MYNET2

The openstack_network_name is used to select IP address for SSH connection. It’s recommended to specify this option in case of multiple networks used for instance to provide more control over network connectivity.

Please note that network_ref relies on Network Services (Fog::Network) and it can be unavailable in your OpenStack installation.

disable_ssl_validation

  disable_ssl_validation: true

Only disable SSL cert validation if you absolutely know what you are doing, but are stuck with an OpenStack deployment without valid SSL certs.
