• Create a partition for the OpenStack instance
• Create a Flavor in the OpenStack instance
• Create an image for the OpenStack instance
• Create an internal network for the OpenStack instance
• Create a Security Group for an OpenStack instance
• Create Keypairs for an OpenStack instance
• Create an Instance in OpenStack
• Soft reboot an instance
• Hard reboot an instance
• Shut off an instance
• Create a snapshot of an instance

• CV0-002 3.6.A. Maintenance schedules

Lab Duration

It will take approximately 45 minutes to complete this lab.

Exercise 1 - Backing-up and Restoring Configuration File

The /etc/openstack_deploy/ directory contains details such as the live inventory, host structure, network information, passwords, and options applied to the configuration files for each service in the OpenStack deployment. In case of a disruption, you can restore the /etc/openstack_deploy/ directory from its backup. To restore the /etc/openstack_deploy/ directory, copy the backup of the directory to your cloud environment.

In this exercise, you will back up and then restore the etc/openstack_deploy/ directory.

Learning Outcomes

After completing this exercise, you will be able to:

• Backup and restore the /etc/openstack_deploy/ directory

Exercise 2 - Maintaining the OpenStack Environment

OpenStack maintenance is needed to ensure that the environment runs smoothly and prevents unexpected downtime.

Thus, it is necessary to ensure there is a maintenance strategy in place. This strategy can be an automatic or a manual provisioned strategy.

In this exercise, you will implement manual maintenance strategies. Keep in mind that these specific tasks can be automated in a production environment to ensure consistency of the tasks performed. Another benefit of automating these specific tasks is that it will run on a schedule and prevent human error.

Learning Outcomes

After completing this exercise, you will be able to:

• Backup and restore the /etc/openstack_deploy/ directory
• Create a partition for the OpenStack instance
• Create a Flavor in the OpenStack instance
• Create an image for the OpenStack instance
• Create an internal network for the OpenStack instance
• Create a Security Group for an OpenStack instance
• Create Keypairs for an OpenStack instance
• Create an Instance in OpenStack
• Soft reboot an instance
• Hard reboot an instance
• Shut off an instance
• Create a snapshot of an instance
