第 3 章 Installing on Azure

Procedure

1. Identify your domain, or subdomain, and registrar. You can transfer an existing domain and registrar or obtain a new one through Azure or another source.

   注意

   For more information about purchasing domains through Azure, see Buy a custom domain name for Azure App Service in the Azure documentation.

2. If you are using an existing domain and registrar, migrate its DNS to Azure. See Migrate an active DNS name to Azure App Service in the Azure documentation.

3. Configure DNS for your domain. Follow the steps in the Tutorial: Host your domain in Azure DNS in the Azure documentation to create a public hosted zone for your domain or subdomain, extract the new authoritative name servers, and update the registrar records for the name servers that your domain uses.

   Use an appropriate root domain, such as openshiftcorp.com, or subdomain, such as clusters.openshiftcorp.com.

4. If you use a subdomain, follow your company’s procedures to add its delegation records to the parent domain.

Procedure

1. From the Azure portal, click Help + support in the lower left corner.

2. Click New support request and then select the required values:

   1. From the Issue type list, select Service and subscription limits (quotas).
   2. From the Subscription list, select the subscription to modify.
   3. From the Quota type list, select the quota to increase. For example, select Compute-VM (cores-vCPUs) subscription limit increases to increase the number of vCPUs, which is required to install a cluster.
   4. Click Next: Solutions.

3. On the Problem Details page, provide the required information for your quota increase:

   1. Click Provide details and provide the required details in the Quota details window.
   2. In the SUPPORT METHOD and CONTACT INFO sections, provide the issue severity and your contact details.
4. Click Next: Review + create and then click Create.

Procedure

1. Log in to the Azure CLI:

   $ az login

   Log in to Azure in the web console by using your credentials.

2. If your Azure account uses subscriptions, ensure that you are using the right subscription.

   1. View the list of available accounts and record the tenantId value for the subscription you want to use for your cluster:

      $ az account list --refresh

      Example output

      [
        {
          "cloudName": "AzureCloud",
          "id": "9bab1460-96d5-40b3-a78e-17b15e978a80",
          "isDefault": true,
          "name": "Subscription Name",
          "state": "Enabled",
          "tenantId": "6057c7e9-b3ae-489d-a54e-de3f6bf6a8ee",
          "user": {
            "name": "you@example.com",
            "type": "user"
          }
        }
      ]

   2. View your active account details and confirm that the tenantId value matches the subscription you want to use:

      $ az account show

      Example output

      {
        "environmentName": "AzureCloud",
        "id": "9bab1460-96d5-40b3-a78e-17b15e978a80",
        "isDefault": true,
        "name": "Subscription Name",
        "state": "Enabled",
        "tenantId": "6057c7e9-b3ae-489d-a54e-de3f6bf6a8ee", 1
        "user": {
          "name": "you@example.com",
          "type": "user"
        }
      }

      1

      Ensure that the value of the tenantId parameter is the UUID of the correct subscription.

   3. If you are not using the right subscription, change the active subscription:

      $ az account set -s <id> 1

      1

      Substitute the value of the id for the subscription that you want to use for <id>.

   4. If you changed the active subscription, display your account information again:

      $ az account show

      Example output

      {
        "environmentName": "AzureCloud",
        "id": "33212d16-bdf6-45cb-b038-f6565b61edda",
        "isDefault": true,
        "name": "Subscription Name",
        "state": "Enabled",
        "tenantId": "8049c7e9-c3de-762d-a54e-dc3f6be6a7ee",
        "user": {
          "name": "you@example.com",
          "type": "user"
        }
      }

3. Record the values of the tenantId and id parameters from the previous output. You need these values during OpenShift Container Platform installation.

4. Create the service principal for your account:

   $ az ad sp create-for-rbac --role Contributor --name <service_principal> 1

   1

   Replace <service_principal> with the name to assign to the service principal.

   Example output

   Changing "<service_principal>" to a valid URI of "http://<service_principal>", which is the required format used for service principal names
   Retrying role assignment creation: 1/36
   Retrying role assignment creation: 2/36
   Retrying role assignment creation: 3/36
   Retrying role assignment creation: 4/36
   {
     "appId": "8bd0d04d-0ac2-43a8-928d-705c598c6956",
     "displayName": "<service_principal>",
     "name": "http://<service_principal>",
     "password": "ac461d78-bf4b-4387-ad16-7e32e328aec6",
     "tenant": "6048c7e9-b2ad-488d-a54e-dc3f6be6a7ee"
   }

5. Record the values of the appId and password parameters from the previous output. You need these values during OpenShift Container Platform installation.

6. Grant additional permissions to the service principal. The service principal requires the legacy Azure Active Directory Graph Application.ReadWrite.OwnedBy permission and the User Access Administrator role for the cluster to assign credentials for its components.

   1. To assign the User Access Administrator role, run the following command:

      $ az role assignment create --role "User Access Administrator" \
          --assignee-object-id $(az ad sp list --filter "appId eq '<appId>'" \ 1
             | jq '.[0].objectId' -r)

      1

      Replace <appId> with the appId parameter value for your service principal.

   2. To assign the Azure Active Directory Graph permission, run the following command:

      $ az ad app permission add --id <appId> \ 1
           --api 00000002-0000-0000-c000-000000000000 \
           --api-permissions 824c81eb-e3f8-4ee6-8f6d-de7f50d565b7=Role

      1

      Replace <appId> with the appId parameter value for your service principal.

      Example output

      Invoking "az ad app permission grant --id 46d33abc-b8a3-46d8-8c84-f0fd58177435 --api 00000002-0000-0000-c000-000000000000" is needed to make the change effective

      For more information about the specific permissions that you grant with this command, see the GUID Table for Windows Azure Active Directory Permissions.

   3. Approve the permissions request. If your account does not have the Azure Active Directory tenant administrator role, follow the guidelines for your organization to request that the tenant administrator approve your permissions request.

      $ az ad app permission grant --id <appId> \ 1
           --api 00000002-0000-0000-c000-000000000000

      1

      Replace <appId> with the appId parameter value for your service principal.
