Managing your Public Cloud Instances in Horizon
Find out how to manage your Public Cloud projects via the Horizon interface
Last updated 25th January 2022
Objective
Beside the OVHcloud Control Panel, you can also manage your Public Cloud projects via the Horizon interface. In this interface, you will find all of your infrastructure (instances, backups, disks, SSH keys, etc.) and storage projects there (including the list of your containers).
This guide details how to manage your Public Cloud instances via the Horizon interface.
Requirements
- You need to have created a Public Cloud instance in your OVHcloud Control Panel or through the Horizon interface
- An SSH key
Access the management interface for the instance
First, log into the Horizon interface.
Unlike the OVHcloud Control Panel, Horizon separates your services according to their region. You can choose the region from the menu in the top left-hand corner:
Click the Compute menu on the left-hand side, then select Instances. On that page you will see a summary of all your instances. There will be several pieces of information displayed here:
- The model of your instance (Flavor)
- Its name, power state, and time since created
- Your instance’s IPv4 and IPV6 address
- Its associated private network and private IPv4 address
- Its status
- The image used to install the instance (if applicable)
Launch Instance
This option allows you to create an instance. Please refer to this guide for more information.
Delete Instances
This option allows you to delete several instances at once, make sure to tick the box to the left of the instance name.
More Actions
Use this menu to perform the following actions on one or more instances. First, ensure that you tick the box to the left of the instance name:
- Start Instances: This option allows you to reboot one or more instances in « shutoff or off » status.
- Shut Off Instances: This option allows you to suspend one or more instances.
- Soft Reboot Instances: This option allows you to perform a software reboot on one or more instances.
Create snapshot: This option allows you to create a snapshot of your instance. Consult this guide for more information.
Modify an instance
In the management interface for the Instance, select the option you want from the dropdown list.
- Attach Interface: This option allows you to add one or more private interfaces to your instance via the VLAN. For more information, refer to this section of the corresponding guide.
- Detach Interface: This option allows you to delete an interface linked to an instance. For more information, refer to this section of the corresponding guide.
- Edit Instance: This option allows you to change the instance name and security groups.
The options in red indicate the possibility of data loss during the process, always make sure you have a backup of your data before making any changes to your instance.
Resize an instance
With the Public Cloud, you can increase the resources your instance has with just a few clicks.
Only upscaling is possible for classic models. In addition, this manipulation causes the instance to be shut down for the time of the operation.
Flex instances allow resizing to higher or lower models due to a locked single disk size.
Log into the Horizon interface, and make sure you are in the correct region. You can verify this on the top left corner.
Next, click on theCompute menu on the left side and select Instances. Select Resize Instance in the drop list for the corresponding instance.
- Template Selection Tab (Flavor Choice): this section shows the current template (old flavor) and allows you to select a new template (new flavor) for the instance resource.
-
Flavor Details. In this section, you will see the resources associated with the new template you have chosen.
-
Project Limits. View here the occupied resources compared to the total resources allocated to the project.
Please note that you cannot switch models when resizing an instance. A resizing can only be done from a Linux model to another Linux model or from a Windows model to another Windows model.
- Advanced Options. This section allows you to manage the Disk Partition and Server Group.
Once the configuration is complete, click on Resize.
Resizing a disk in Windows
When performing a resize for a Windows Instance, please note that the partition size is not automatically updated, so you will have to extend it using the disk manager:
Right-click on the Start menu and launch the disk manager by clicking on Disk Management:
Right-click on the main partition, then click on Extend Volume.
In the Extend Volume Wizard menu, click on Next to proceed. In the next tab, choose the disk resources to extend and click on Next.
Once done, click on Finish to confirm your choice.
The new disk size will then be displayed in the disk manager.
Rebuild an instance
This option allows you to reconfigure your instance on a new basis, or simply change the operating system.
This operation will delete the instance’s data.
- Select
Rebuild Instancefrom the drop-down list for the instance.
- Select the image for reconstruction.
- Select the type of partitioning ("Automatic" or "Manual"). This is optional.
- Finally, click on
Rebuild Instance, this operation may take a few minutes.
Shelve or pause an instance
To find out how to shelve or pause an instance, please refer to this guide.
Access the instance console
If you lose access to your instance, either because of a bad configuration, or because the SSH service is down, you can always reconfigure your instance using the VNC console.
You can access your instance directly through the VNC console. Only you will have to set up a password for the root user beforehand. Consult this guide for more information. The VNC console can also be used as a first approach during a malfunction, to establish a diagnostic using the analysis of your instance's startup phase.
From the drop-down list for the instance, select Console.
- The instance console will appear.
If the console no longer responds to the keyboard input, click on the status bar. To exit full-screen mode, click the browser's back button.
Instance console
Reboot an instance
There are two methods for rebooting an instance:
- Soft Reboot Instance (Software)
- Hard Reboot Instance (Hardware)
From the drop-down list for the instance, select either Soft Reboot Instance or Hard Reboot Instance.
Then confirm your request in the window that pops up.
Delete an instance
If you no longer need one of your instances, you can delete it at any time.
The data stored on the instance will be permanently deleted. You can always create a backup of this instance if you want to keep the data and restart an identical instance later.
From the drop-down list for the instance, select Delete Instance.
Then click Confirm to start the process.
Once deleted, you will no longer be charged for your instance, and you will not be able to recover it.
