<title>CloudMonkey</title>
<para>CloudMonkey is the &PRODUCT; Command Line Interface (CLI). It is written in Python and leverages Marvin. CloudMonkey can be used both as an interactive shell and as a command line tool which simplifies &PRODUCT; configuration and management.</para>
<warning>
<para>CloudMonkey is still under development and should be considered a Work In Progress (WIP), the wiki is the most up to date documentation:</para>

<title>Configuration</title>
<para>To configure CloudMonkey you can edit the .cloudmonkey_config file in the user's home directory as shown below. The values can also be set interactively at the cloudmonkey prompt</para>
<programlisting>
$ cat .cloudmonkey_config
[CLI]
protocol = http
asyncblock = true
color = true
prompt = cloudmonkey>
history_file = /Users/sebastiengoasguen/.cloudmonkey_history
host = localhost
path = /client/api
port = 8080

timeout = 600
log_file = /Users/sebastiengoasguen/.cloudmonkey_log
</programlisting>
<para>The values can also be set at the cloudmonkey prompt. The API and secret keys are obtained via the &PRODUCT; UI or via a raw api call.</para>
<programlisting>
<![CDATA[

</programlisting>
<para>You can use cloudmonkey to interact with a local cloud, and even with a remote public cloud. You just need to set the host value properly and obtain the keys from the cloud administrator.</para>
</section>
<section id="interactivecli">
<title>Interactive Shell Usage</title>
<para>To start learning cloudmonkey, the best is to use the interactive shell. Simply type cloudmonkey at the prompt and you should get the interactive shell.</para>
<para>At the cloudmonkey prompt press the tab key twice, you will see all potential verbs available. Pick on, enter a space and then press tab twice. You will see all actions available for that verb</para>

<para>Note the required arguments necessary for the calls.</para>
<note><para>To find out the required parameters value, using a debugger console on the &PRODUCT; UI might be very useful. For instance using Firebug on Firefox, you can navigate the UI and check the parameters values for each call you are making as you navigate the UI.</para></note>

<title>Starting a Virtual Machine instance with CloudMonkey</title>
<para>To start a virtual machine instance we will use the <emphasis>deploy virtualmachine</emphasis> call.</para>
<programlisting>
<![CDATA[
cloudmonkey>deploy virtualmachine -h
Creates and automatically starts a virtual machine based on a service offering, disk offering, and template.
Required args: serviceofferingid templateid zoneid

]]>
</programlisting>
<para>The required arguments are <emphasis>serviceofferingid, templateid and zoneid</emphasis></para>
<para>In order to specify the template that we want to use, we can list all available templates with the following call:</para>
<programlisting>
<![CDATA[
cloudmonkey>list templates templatefilter=all
count = 2
template:
========
domain = ROOT
domainid = 8a111e58-e155-4482-93ce-84efff3c7c77
zoneid = e1bfdfaf-3d9b-43d4-9aea-2c9f173a1ae7

size = 2101252608
isready = True
templatetype = SYSTEM
zonename = devcloud
...<snipped>
]]>
</programlisting>
<para>In this snippet, I used DevCloud and only showed the beginning output of the first template, the SystemVM template</para>
<para>Similarly to get the <emphasis>serviceofferingid</emphasis> you would do:</para>
<programlisting>
<![CDATA[
cloudmonkey>list serviceofferings | grep id
id = ef2537ad-c70f-11e1-821b-0800277e749c
id = c66c2557-12a7-4b32-94f4-48837da3fa84
id = 3d8b82e5-d8e7-48d5-a554-cf853111bc50
]]>
</programlisting>
<para>Note that we can use the linux pipe as well as standard linux commands within the interactive shell. Finally we would start an instance with the following call:</para>
<programlisting>

...<snipped>
]]>
</programlisting>
<para>The instance would be stopped with:</para>
<programlisting>
cloudmonkey>stop virtualmachine id=7efe0377-4102-4193-bff8-c706909cc2d2
</programlisting>
<note><para>The <emphasis>ids</emphasis> that you will use will differ from this example. Make sure you use the ones that corresponds to your &PRODUCT; cloud.</para></note>

<section id="scriptingcli">
<title>Scripting with CloudMonkey</title>
<para>All previous examples use CloudMonkey via the interactive shell, however it can be used as a straightfoward CLI, passing the commands to the <emphasis>cloudmonkey</emphasis> command like shown below.</para>
<para><programlisting>$cloudmonkey list users</programlisting></para>
<para>As such it can be used in shell scripts, it can received commands via stdin and its output can be parsed like any other unix commands as mentioned before.</para>
