Real World Vagrant – Automate a Cloudera Manager Build

Note : This course is built on top of the “Real World Vagrant For Distributed Computing – Toyin Akin” course

“NoSQL“, “Big Data“, “DevOps” and “In Memory Database“
technology are a hot and highly valuable skill to have – and this
course will teach you how to quickly create a distributed environment
for you to deploy these technologies on.�

A combination of VirtualBox and Vagrant will transform your desktop
machine into a virtual cluster. However this needs to be configured
correctly. Simply enabling multinode within Vagrant is not good enough.
It needs to be tuned. Developers and Operators within large enterprises,
including investment banks, all use Vagrant to simulate Production
environments.�

After all, if you are developing against or operating a distributed
environment, it needs to be tested. Tested in terms of code deployed and
the deployment code itself.

You’ll learn the same techniques these enterprise guys use on your own Microsoft Windows computer/laptop.

Vagrant provides easy to configure, reproducible, and portable work
environments built on top of industry-standard technology and controlled
by a single consistent workflow to help maximize the productivity and
flexibility of you and your team.

This course will use VirtualBox to carve out your virtual
environment. However the same skills learned with Vagrant can be used to
provision virtual machines on VMware, AWS, or any other provider.

If you are a developer,
this course will help you will isolate dependencies and their
configuration within a single disposable, consistent environment,
without sacrificing any of the tools you are used to working with
(editors, browsers, debuggers, etc.). Once you or someone else creates a
single Vagrantfile, you just need to vagrant up and everything is
installed and configured for you to work. Other members of your team
create their development environments from the same configuration. Say
goodbye to “works on my machine” bugs.

If you are an operations engineer,
this course will help you build a disposable environment and consistent
workflow for developing and testing infrastructure management scripts.
You can quickly test your deployment scripts and more using local
virtualization such as VirtualBox or VMware. (VirtualBox for this
course). Ditch your custom scripts to recycle EC2 instances, stop
juggling SSH prompts to various machines, and start using Vagrant to
bring sanity to your life.

If you are a designer, this course will
help you with distributed installation of software in order for you to
focus on doing what you do best: design. Once a developer configures
Vagrant, you do not need to worry about how to get that software running
ever again. No more bothering other developers to help you fix your
environment so you can test designs. Just check out the code, vagrant
up, and start designing.

Here I present a curriculum as to the current state of my Cloudera courses.

My Hadoop courses are based on Vagrant so that you can practice and
destroy your virtual environment before applying the installation onto
real servers/VMs.

I would first practice with Vagrant so that you can carve out a
virtual environment on your local desktop. You don’t want to corrupt
your physical servers if you do not understand the steps or make a
mistake.

.

I would then, on the virtual servers, deploy Cloudera Manager plus
agents. Agents are the guys that will sit on all the slave nodes ready
to deploy your Hadoop services

.

Then deploy the Hadoop services across your cluster (via the
installed Cloudera Manager in the previous step). We look at the logic
regarding the placement of master and slave services.

.

You can also automate the deployment of the Hadoop services via
Python (using the Cloudera Manager Python API). But this is an advanced
step and thus I would make sure that you understand how to manually
deploy the Hadoop services first.

.

There is also the upgrade step. Once you have a running cluster, how
do you upgrade to a newer hadoop cluster (Both for Cloudera Manager and
the Hadoop Services).

Frequently Asked Questions

How long do I have access to the course materials?

You can view and review the lecture materials indefinitely, like an on-demand channel.

Can I take my courses with me wherever I go?

Definitely! If you have an internet connection, courses on Udemy are available on any device at any time. If you don’t have an internet connection, some instructors also let their students download course lectures. That’s up to the instructor though, so make sure you get on their good side!
