Create cloud provider configuration
Before you can deploy universes using YugabyteDB Anywhere (YBA), you must create a provider configuration. Create a Microsoft Azure provider configuration if your target cloud is Azure.
When deploying a universe, YBA uses the provider configuration settings to do the following:
Create VMs on Azure using the following:
- the resource group
- specified regions and availability zones (this can be a subset of those specified in the provider configuration)
- a Linux image
Provision those VMs with YugabyteDB software
Note: YBA needs network connectivity to the VMs, resource group for the provisioning step above, and for subsequent management, as described in Cloud prerequisites.
You need to add the following Azure cloud provider credentials via YBA:
- Subscription ID
- Tenant ID
- SSH port and user
- Application client ID and secret
- Resource group
YBA uses the credentials to automatically provision and deprovision YugabyteDB instances.
For more information on setting up an Azure account and resource groups, refer to Cloud prerequisites.
Navigate to Configs > Infrastructure > Microsoft Azure to see a list of all currently configured Azure providers.
Create a provider
To create an Azure provider:
Click Create Config to open the Create Azure Provider Configuration page.
Enter the provider details. Refer to Provider settings.
Click Create Provider Configuration when you are done and wait for the configuration to complete.
This process includes configuring a network, subnetworks in all available regions, firewall rules, VPC peering for network connectivity, and a custom SSH key pair for YBA-to-YugabyteDB connectivity.
When the configuration is completed, you can see all the resources managed by YBA in your resource group, including virtual machines, network interface, network security groups, public IP addresses, and disks.
If you encounter problems, see Troubleshoot Azure cloud provider configuration.
View and edit providers
To view a provider, select it in the list of AZU Configs to display the Overview.
To edit the provider, select Config Details, make changes, and click Apply Changes. For more information, refer to Provider settings. Note that for YBA version 2.20.1 and later, depending on whether the provider has been used to create a universe, you can only edit a subset of fields such as the following:
- Provider Name
- Client Secret
- Regions - You can add regions and zones to an in-use provider. Note that you cannot edit existing region details, delete a region if any of the region's zones are in use, or delete zones that are in use.
To view the universes created using the provider, select Universes.
To delete the provider, click Actions and choose Delete Configuration. You can only delete providers that are not in use by a universe.
Enter a Provider name. The Provider name is an internal tag used for organizing cloud providers.
- Client ID represents the ID of an application registered in your Azure Active Directory.
- Client Secret represents the secret of an application registered in your Azure Active Directory. You need to enter the
Valueof the secret (not the
- Resource Group represents the group in which YugabyteDB nodes compute and network resources are created. Your Azure Active Directory application (client ID and client secret) needs to have
Virtual Machine Contributorroles assigned for this resource group.
- Subscription ID is required for cost management. The virtual machine resources managed by YBA are tagged with this subscription.
- Tenant ID represents the Azure Active Directory tenant ID which belongs to an active subscription. To find your tenant ID, follow instructions provided in How to find your Azure Active Directory tenant ID.
- Private DNS zone lets you use a custom domain name for the nodes in your universe. For details and instructions, see Define a private DNS zone.
You can specify a region as follows:
Click Add Region.
Use the Add Region dialog to select a region and provide a virtual network name from your Azure portal.
Optionally, specify the security group, if the database VM is in a different network than YBA.
Provide a URN to a marketplace image or a shared gallery image by following instructions provided in Use a shared image gallery. If you are using custom images, you need to specify the SSH port and user, as described in SSH Key Pairs.
Click Add Zone and provide a mapping of subnet IDs to use for each availability zone you wish to deploy. This is required for ensuring that YBA can deploy nodes in the correct network isolation that you need in your environment.
Click Add Region.
SSH Key Pairs
To be able to provision cloud instances with YugabyteDB, YBA requires SSH access. The following are two ways to provide SSH access:
- Enable YBA to create and manage Key Pairs. In this mode, YBA creates SSH Key Pairs and stores the relevant private key so that you will be able to SSH into future instances.
- Use your own existing Key Pairs. To do this, provide the name of the Key Pair, as well as the private key content, and the corresponding SSH user.
You can customize the Network Time Protocol server, as follows:
Select Use AZU's NTP server to enable cluster nodes to connect to the Azure internal time servers. For more information, consult the Microsoft Azure documentation such as Time sync for Linux VMs in Azure.
Select Specify Custom NTP Server(s) to provide your own NTP servers and allow the cluster nodes to connect to those NTP servers.
Select Assume NTP server configured in machine image to prevent YBA from performing any NTP configuration on the cluster nodes. For data consistency, you will be responsible for manually configuring NTP.
ImportantUse this option with caution. Time synchronization is critical to database data consistency; failure to run NTP may cause data loss.
Configuring Azure Portal
Obtain Azure resource IDs
To find an Azure resource's ID, navigate to the resource in question and click JSON View at the top right, as per the following illustration:
Azure resource IDs typically have the following format:
Define a private DNS zone
You may choose to define a private DNS zone to instruct YBA to register the universe name to all of the IP addresses in the universe in that DNS zone. For more information, see What is a private Azure DNS zone.
You can set a private DNS zone as follows:
On the Azure portal, create the Private DNS Zone, as per the following illustration:
Navigate to the resource page and click Settings > Virtual Network Links, as per the following illustration:
Add a link to the virtual network to which you want it to be connected. For more information, see Create an Azure private DNS zone using the Azure portal.
To use the private DNS zone in YBA, add either the resource ID or the name of the DNS zone to the Private DNS Zone field of the Cloud Provider Configuration page in the YBA UI.
If the private DNS zone is defined by an ID, YBA will use it together with the default subscription ID and the resource group. If the private DNS zone is defined by a full URL that contains both the subscription ID and resource group, then these two values will be used instead of default values.
In the setup example shown in the following illustration, the private DNS zone is specified as
dns.example.com, and the resource group is explicitly specified as
In the following setup example, a complete resource ID is specified for the private DNS zone:
The preceding setting specifies the resource group as
different-rg and the DNS zone as
different-rg resource group in the resource ID overrides the setting in the Resource Group field, as shown in the following illustration:
Use a shared image gallery
You can use shared image galleries as an alternative to using marketplace image URNs. A gallery allows you to provide your own custom image to use for creating universe instances. For more information on shared image galleries, refer to Store and share images in an Azure Compute Gallery.
You set up a shared gallery image on Azure as follows:
On the Azure portal, create a shared image gallery.
Create an image definition.
Create a VM of which you want to take a snapshot.
Navigate to the VM and click Capture on the top menu.
Fill in the information and then choose the gallery and image definition you created in the previous steps, as per the following illustration:
Ensure that the images are replicated to each region in which you are planning to use them. For example, configuration shown in the following illustration would only work for US East:
To use the image in YBA, enter the image version's resource ID into the Marketplace Image URN / Shared Gallery Image ID field of the Specify Region Info dialog.
The gallery image ID could be defined by a full URL containing a subscription ID, a resource group name, and the resource name itself. If the subscription ID or the resource group is different from the default values, YBA will use them instead.
