How to create an instance in OpenStack

Question

Hi everyone,

I worked in AWS and its services. We know in AWS, EC2 is one that provides Compute-as-a-service. But when we launch an instance in AWS, in background it attached all the necessary things for that instance. OpenStack also has the same service. For Compute service it has nova. But I am not able to create an instance in OpenStack. Can anyone help me?

Thank You

Hi@akhtar,

When we try to launch an instance in AWS, we need AMI, security groups etc. In OpenStack also we need image, security group etc. So, First create an image and security group and after that follow the below given steps.

• Move to Project -> Instances and hit on Launch Instance button and a new window will appear.

• On the first screen add a name for your instance, leave the Availability Zone to nova, use one instance count and hit on Next button to continue

• Next, select Image as a Boot Source, add the Cirros test image created earlier by hitting the + button and hit Next to proceed further.

• Allocate the virtual machine resources by adding a flavor best suited for your needs and click on Next to move on.

• Finally, add one of the OpenStack available networks to your instance using the + button and hit on Launch Instance to start the virtual machine.
