Getting Started with VEXXHOST¶

VEXXHOST is a cloud computing host which provides Canadian cloud computing services which are based in Monteral and use the libcloud OpenStack driver. VEXXHOST currently runs the Havana release of OpenStack. When provisioning new instances, they automatically get a public IP and private IP address. Therefore, you do not need to assign a floating IP to access your instance after it's booted.

Cloud Provider Configuration¶

To use the openstack driver for the VEXXHOST public cloud, you will need to set up the cloud provider configuration file as in the example below:

/etc/salt/cloud.providers.d/vexxhost.conf: In order to use the VEXXHOST public cloud, you will need to setup a cloud provider configuration file as in the example below which uses the OpenStack driver.

my-vexxhost-config:
  # Set the location of the salt-master
  #
  minion:
    master: saltmaster.example.com

  # Configure VEXXHOST using the OpenStack plugin
  #
  identity_url: http://auth.api.thenebulacloud.com:5000/v2.0/tokens
  compute_name: nova

  # Set the compute region:
  #
  compute_region: na-yul-nhs1

  # Configure VEXXHOST authentication credentials
  #
  user: your-tenant-id
  password: your-api-key
  tenant: your-tenant-name

  # keys to allow connection to the instance launched
  #
  ssh_key_name: yourkey
  ssh_key_file: /path/to/key/yourkey.priv

  driver: openstack

注解

在 2015.8.0 版更改.

The provider parameter in cloud provider definitions was renamed to driver. This change was made to avoid confusion with the provider parameter that is used in cloud profile definitions. Cloud provider definitions now use driver to refer to the Salt cloud module that provides the underlying functionality to connect to a cloud host, while cloud profiles continue to use provider to refer to provider configurations that you define.

Authentication¶

All of the authentication fields that you need can be found by logging into your VEXXHOST customer center. Once you've logged in, you will need to click on "CloudConsole" and then click on "API Credentials".

Cloud Profile Configuration¶

In order to get the correct image UUID and the instance type to use in the cloud profile, you can run the following command respectively:

# salt-cloud --list-images=vexxhost-config
# salt-cloud --list-sizes=vexxhost-config

Once you have that, you can go ahead and create a new cloud profile. This profile will build an Ubuntu 12.04 LTS nb.2G instance.

/etc/salt/cloud.profiles.d/vh_ubuntu1204_2G.conf:

vh_ubuntu1204_2G:
  provider: my-vexxhost-config
  image: 4051139f-750d-4d72-8ef0-074f2ccc7e5a
  size: nb.2G

Provision an instance¶

To create an instance based on the sample profile that we created above, you can run the following salt-cloud command.

# salt-cloud -p vh_ubuntu1204_2G vh_instance1

Typically, instances are provisioned in under 30 seconds on the VEXXHOST public cloud. After the instance provisions, it will be set up a minion and then return all the instance information once it's complete.

Once the instance has been setup, you can test connectivity to it by running the following command:

# salt vh_instance1 test.ping

You can now continue to provision new instances and they will all automatically be set up as minions of the master you've defined in the configuration file.
