Terminating instances is very simple when using OpenStack Dashboard.
Load a web browser, point it to our OpenStack Dashboard address at http://192.168.100.200/, and log in as a user, such as the demo user created in the Adding users to Keystone recipe of Chapter 1, Keystone – OpenStack Identity Service, with the password openstack.
To terminate instances by using OpenStack Dashboard, carry out the following steps:
- Select the Instances tab and choose the instance to be terminated by selecting the checkbox next to the instance name (or names), and then click on the red Terminate Instances button:
- We will be presented with a confirmation screen. Click on the Terminate Instances button to terminate the selected instance:
- We will be presented with the Instances screen with a confirmation that the instance has been terminated successfully.
Terminating instances by using OpenStack Dashboard is easy. We select our running instance and click on the Terminate Instances button, which is highlighted when an instance is selected. After clicking on the Terminate Instances button, we are asked to confirm this action to minimize the risk of accidentally terminating an instance.
