MUNI PA200 project 2
The plot
You are a cloud administrator at a startup. Your company needs to establish its presence on the Internet.
For that purpose they plan to purchase a service from an IaaS company and maintain a free and open
source content management system (CMS) there.
Your assignment is to plan and orchestrate the deployment of a CMS platform on the OpenStack cloud.
Technical requirements
To ensure repeatable and automated deployment of the infrastructure, you should rely on the OpenStack
HEAT for deployment orchestration. Your project two task boils down to creating and instantiating a HOT
template which deploys the Wordpress application.
Your installation should span across two OpenStack instances - one for hosting the SQL database (e.g.
MariaDB), the other for the WordPress system.
Both instances can use any Linux OS image available on the cloud. The kind of the image should be made
configurable at the deployment time. The choice of the image should go through some validation to make
sure the chosen image exists in the OpenStack Glance image repository.
The VM flavors being used by both instances should be made configurable at the deployment time. The
choice of flavour should go through some validation to make sure the chosen flavor exists in OpenStack
Nova.
Configurable HOT template parameters should have some reasonable defaults where it makes sense.
Though the use of environment file is encouraged for easier deployment customization.
The SSH key should be injected into both instances at the deployment time.
Configuration that needs to be shared between instances (such as DBMS address, credentials etc) should
be transferred through cloud-init.
Successfully instantiated HOT template should report the URL of the WordPress site. The site should be
available for browsing over public Internet.
Note
No DNS name is required, just IP address would suffice.
DB instance requirements
DB instance should have around 1GB of RAM. DB instance should mount a 1GB block storage volume,
allocated by OpenStack Cinder, to keep the DB files on a separate persistent volume.
All DBMS credentials should be made configurable at the deployment time and pass through some
validation to ensure reasonably strong passwords.
Web instance requirements
Web instance should have around 1GB of RAM and no external storage configured. Web instance should
have a floating IP assigned, so that it becomes available over the Internet.
Web instance should have a security group applied that protects OS services from attacks over the
Internet. Though HTTP and SSH services should be made accessible.
Expected outcome
Project result should be uploaded as a HOT template file (.yaml) along with a sample environment file to
the homework vault at MUNI IS.
Your teacher will evaluate your work by running your HOT template against MUNI OpenStack instance.
