Cloudy building blocks

To build a Cloud we need: - primary storage - secondary storage - zone | pod | cluster - at least 1 hypervisor

Fully automatic….




Cosmic UI

user: adminpass: passworddomain: <empty>




Check Cosmic UI




Check Cosmic UI

Wait until the systemVMs are ready. This may take ~5 minutes.




Check Cosmic UI




Starting your first VM




TemplatesThe only template available is ‘Tiny’, which is a very small template.

It is registered without a password service.

The default user/pass is root/password.




Template properties

Let’s edit the template properties and check the ‘password enabled’ checkbox.

Click to save.




Copy/paste to use later on (root passwd)

Random password




Console Proxy VM serves this console

Accessing the console




Global settings

We may want to bump this setting to 12

We’ll show you how to make that easy..




We started the Mgt server using Jetty.Cosmic is a Java app. So, let’s stop Jetty and start Tomcat.

That makes stop/start easier :-)

$ ssh cs1 $ killall -9 java $ ps aux | grep java $ cp /data/git/cs1/cosmic/cosmic-client/target/cloud-*.war ~tomcat/webapps/client.war $ systemctl start tomcat

We’ll drop the war we compiled before into Tomcat

It’s Java!

Make sure all is gone..




It’s Java!

[root@cs1 webapps]# systemctl status tomcat● tomcat.service - Apache Tomcat Web Application Container Loaded: loaded (/usr/lib/systemd/system/tomcat.service; disabled; vendor preset: disabled) Active: active (running) since Tue 2016-06-28 20:58:10 CEST; 11min ago

$ systemctl status tomcat

The UI / API will be back in a few minutes…

$ tail -n 100 /var/log/cosmic/management/management-server.log




Copy/paste to use later on (root passwd)

Random (longer) password




Metrics




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 your VM

Test from your laptop or from devops box




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

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.
