Overview

OpenStack is used for creating and managing cloud computing platforms for public and private clouds. Our integration includes multiple automation and provisioning methods. You can use it to deploy VPS Hosting, Cloud hosting (virtual Datacenters) or DIY Cloud and VPS packages.

Activating the module

  1. If the module is included in your HostBill edition you can download it from your client portal.
  2. If the module is not included in your HostBill edition you can purchase it from our marketplace and then download it from the client area.
  3. Once you download the module extract it in the main HostBill directory.
  4. Go to Settings → Modules → Hosting Modules, find and activate OpenStack module.

Connecting HostBill with OpenStack

  1. Proceed to Settings → Apps → Add new App
  2. From the Applications list select OpenStack
  3. On the Add New App page:
    • Enter a Name that identifies this connection
    • Enter a Hostname or an IP Address
    • Enter your Username
    • Enter the Password for your username
    • Enter the Port used by Identity API
    • Enter the Admin project name
    • Enter the Domain name
    • Check Secure if your Openstack API  works over HTTPS
    • Select Interface type for API Connections, OpenStack can advertise different endpoint URLs based on interface type, you need to select the type that can be accessed from hostbill server.
    • Check Override endpoint hostname if you want to replace the hostname for each endpoint returned in API catalog with the one used for Identity API connection.
    • Check Domain scope for identity If your Openstack deployment enforces that action on Identity API should use domain scoped tokens.
    • Select Default Console type
    • Enter Console URL if you want to use a non-standard one, leave it empty otherwise.
    • Enter Horizon URL if you do not want to use the one generated from IP address/hostname, leave it empty otherwise.

      4. Verify entered credentials by clicking Test Connection to check if HostBill can connect.
      5. Save Changes

How to access instances through SSH using root password?

This module supports two ways of settings up SSH access with password authentication: through root password injection and cloud-init scripts.

You can read more on how to enable password injection for different hypervisors here: http://docs.openstack.org/admin-guide/compute-admin-password-injection.html

To use cloud-init script, you will need to enter it in your product configuration, under "Misc" tab.

It allows you to use "$password" variable that will be replaced with the actual root password when a new VM is created.


User Data Scripts

It is possible to use smart templates for user data script, you can access $service, $client, $forms and $password variables to customize your script.

Please refer to this list to find out the proper variable names - Available Email / Mobile Notifications Variables

You can access form components values through $forms variable, this guide illustrates how to find proper variable names - Forms: Accessing Forms elements in email templates

cloud-config
#cloud-config
hostname: {$service.domain}
users:
  - name: {$forms.username.value}
	gecos: {$client.firstname} {$client.lastname}
	passwd: {$password|mkpasswd}
    sudo: ['ALL=(ALL) NOPASSWD:ALL']
    groups: sudo
    shell: /bin/bash
runcmd:
  - {$forms.recipe.variable_id}
  - restart ssh
output: {literal}{all: '| tee -a /var/log/cloud-init-output.log'}{/literal}

The user data script is processed by the smarty template engine. If your script includes curly bracers (`{` or `}`) that are not part of a variable or function you will need to encapsulate it in `{literal} ... {/literal}` statement. 

mkpasswd

You can use `mkpasswd` variable modifier to generate password hash. It output can be modified with additional parameters {$var|mkpasswd[:$method[:$salt[:$rounds]]]]}.

  • $method - des, md5,  blowfish, sha256 or sha512, default is sha512.
  • $salt - variable or a string to be used as salt, use `null` to generate salt automatically.
  • $rounds - number of iterations for sha256 and sha512, cost for blowfish.

For example to generate a sha512 hash, with random salt and 10000 rounds use: {$password|mkpasswd:sha512:null:10000}

Solving connection problems

Problem: Connection timed out 

Solution: Make sure that HostBill server is able to connect to your Openstack server.  After authentication Openstack returns with list of available api endpoints, HostBill will test those endpoints using admin api interface (adminURL). Make sure that url provided in error message is accessible from your server.

Problem:  Admin API interface is not available for some services (eg. compute, network)

Solution: Rename includes/modules/Hosting/openstack/endpoints.php.example to endpoints.php, you can edit that file to select which url type will be used for each service.

Problem: Test connection returns: 500 Internal Server Error. Test did not completed, check your error logs for more information.

Solution: There was an error while testing connection status, check Extras → System Logs → Error logs for more information.
