Deploy your cloud

[root@mct-devops1 deploy]# virsh list
Id Name State
----------------------------------------------------
3 cs1 running
4 xen1 running
5 xen2 running
Your cloud for today
XenServer cluster
CloudStack management
Give it some time to ﬁnish the setup..

[root@mct-devops1 deploy]# ssh root@xen2
[root@xen2 ~]# xe pool-join master-address=xen1
master-username=root master-password=password
[root@xen2 ~]# xe host-list
uuid ( RO) : da233ac0-61a2-47e9-8e6a-8ffa19ebc443
name-label ( RW): xen2
name-description ( RW): Default install of XenServer
uuid ( RO) : 1651accd-e05e-4a00-be7d-84263513d72e
name-label ( RW): xen1
name-description ( RW): Default install of XenServer
Prepare XenServer cluster
Should display 2 hosts
In reality, you’d also turn on poolHA

[root@mct-devops1 deploy]# ssh root@cs1
[root@cs1 ~]# screen
[root@cs1 ~]# cd /data/shared/helper_scripts/cloudstack
[root@cs1 ~]# ./prepare_cloudstack_compile.sh
Prepare CloudStack mgt
This will setup all dependencies

[root@cs1 ~]# cd /data/git/$HOSTNAME/cloudstack
[root@cs1 ~]# git checkout 4.4
[root@cs1 ~]# cd /data/shared/helper_scripts/cloudstack
[root@cs1 ~]# ./build_run.sh
Compile CloudStack mgt
Compile in progress…
The UI should be up after a few minutes, available from your laptop: http://cs1.cloud.lan:8080/client/ or
http://192.168.22.61:8080/client/

CloudStack UI
user: admin
pass: password
domain: <empty>
We’re not going to use the UI now.

Deploy Data Center
[root@cs1 ~]# CTRL+a c
[root@cs1 ~]# cd /data/git/$HOSTNAME/cloudstack
[root@cs1 cloudstack]# mvn -P developer -pl :cloud-marvin
[root@cs1 cloudstack]# pip install --upgrade tools/marvin/dist/Marvin-*.tar.gz
--allow-external mysql-connector-python
Install Marvin:
Successfully installed Marvin-4.4.1 ddt-1.0.0 ecdsa-0.13 paramiko-1.15.2

Deploy Data Center
[root@cs1 cloudstack]# ./scripts/storage/secondary/cloud-install-sys-tmplt
-m /data/storage/secondary/MCCT-SHARED-1/ -u http://
jenkins.buildacloud.org/view/4.4/job/cloudstack-4.4-systemvm64/
lastSuccessfulBuild/artifact/tools/appliance/dist/
systemvm64template-4.4-2015-06-23-xen.vhd.bz2
-h xenserver -o localhost -r root -e vhd
Install SystemVM template:
Get URL from: http://jenkins.buildacloud.org/view/4.4/job/
cloudstack-4.4-systemvm64/lastSuccessfulBuild/
Successfully installed system VM template to /data/storage/secondary/MCCT-SHARED-1/template/tmpl/1/1/
This will install systemVM template

Deploy Data Center
[root@cs1 ~]# python /data/git/$HOSTNAME/cloudstack/tools/marvin/marvin/
deployDataCenter.py -i /data/shared/marvin/mct-zone1-xen1.cfg
Deploy DC using Marvin:
This will setup your data center using the two XenServers

Check CloudStack UI

Check CloudStack UI
Wait until the systemVMs are ready.This may take ~15 minutes.

Systemvm template copy in progress

Yeah, victory!
When they are ready, we can move on and add aVM template!
Secondary Storage VM handles this

Adding aVM template
When they are ready, we can move on and spin up someVMs!
[root@cs1 ~]# cd /data/shared/helper_scripts/cloudstack/
[root@cs1 ~]# ./add_os_templates.sh
Secondary Storage VM download successfully
Using this Tiny template

Starting your ﬁrstVM

Copy/paste to use later on (root passwd)

Console Proxy VM serves this console

Forwarding a port
We’ll set up port forwarding
Click Networking, select your network, then IP Addresses
We’ll open the port in the ﬁrewall

Forwarding a port
Fill-in this form to forward SSH
Result looks like this
Fill-in this form to open ﬁrewall for SSH
Result looks like this

SSH to yourVM
Test from your laptop or from mct-devopsX

Using the API

Learn API calls using FireBug
API docs: 
https://cloudstack.apache.org/api/apidocs-4.4/TOC_Root_Admin.html
https://getﬁrebug.com/releases/lite/chrome/
Use this icon to start FireBug
Install using this page

Play with CloudMonkey
It has been pre-setup on your cs1 VM

Deploy with CloudMonkey
Deploy another VM in the same network, using CloudMonkey.
Exercise:
TIP: You may want to deploy one via UI ﬁrst and watch FireBug send API calls…
TIP: You can do this by sending just one API call.

CloudStackOps
[root@cs1 ~]# cd /data/shared/helper_scripts/
[root@cs1 cloudstack]# ./setup_cloudstackOps.sh
[root@cs1 cloudstack]# source /data/git/cs1/python_cloud/bin/activate
(python_cloud)[root@cs1 cloudstack]# cd /data/git/cs1/cloudstackOps
(python_cloud)[root@cs1 cloudstack]# python listVirtualMachines.py -o MCCT-XEN-1
