Getting Started with OpenStack Horizon

Introduction

To get started with using your cloud, we introduce Horizon, OpenStack's dashboard. It is accessible through a web browser and allows a user to interact with the cloud. As an administrator, most of the cloud can be managed this way.

How to Log in to Horizon

The Horizon administrator password is present in a file within the cloud itself. This section walks you through the steps required to obtain this password.

Step 1: Log in to OpenMetal Central

To get started, navigate to OpenMetal Central and log in.

You can also manually retrieve the Horizon password from the hardware node manually, this method is detailed in Step 4b, If you wish to jump right in proceed to Step 5.

Step 4b: Obtain Horizon Password Via SSH

During cloud creation, your SSH public key was added to each hardware node. With this key, you are able to log in as root using SSH. To SSH in, ensure you have one node's IP address and the private key on the system you use to access your cloud. To find your cloud's hardware node IP addresses, click Assets on the cloud's details page.

The IP address for each node is listed under the Public IP column. You can SSH into any of the nodes for this step. Select an IP from this list, then use SSH to log in.

Requirements to SSH into a node

To SSH into a hardware node, ensure these requirements are met:

• Username: root
• Authentication: SSH key pair
• IP address of a hardware node

As an example, we demonstrate using SSH to log in to the first hardware node, located by 173.231.254.165. The SSH key file for this example is ~/.ssh/id_rsa. Ensure you specify the appropriate key and IP address for this step.

For example:

ssh -i ~/.ssh/id_rsa root@173.231.254.165

Once logged in, search for keystone_admin_password inside of /etc/kolla/passwords.yml.

For example:

# grep keystone_admin_password /etc/kolla/passwords.yml
keystone_admin_password: xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

Step 5: Log in to Horizon

You can now log in to Horizon using the credentials obtained from the previous section. The username for the Horizon administrator account is admin.
