This tutorial may incur costs. Use the Cost Estimator to generate a cost estimate based on your projected usage. {: tip}

This tutorial is part of series, and requires that you have completed the related tutorials in the presented order. {: important}

In this tutorial, you will deploy {{site.data.keyword.dns_full_notm}} for a VMware Deployment in {{site.data.keyword.vpc_short}}. {{site.data.keyword.dns_full_notm}} will be used and your {{site.data.keyword.vpc_short}} will be configured to access and use the deployed DNS serrvice. {: shortdesc}

Objectives

{: #vpc-bm-vmware-dns-objectives}

In this tutorial {{site.data.keyword.dns_full_notm}} is used as the {{site.data.keyword.dns_full_notm}} solution for the VMware Deployment.

Before you begin

{: #vpc-bm-vmware-dns-prereqs}

This tutorial requires:

• Common prereqs for VMware Deployment tutorials in {{site.data.keyword.vpc_short}}

This tutorial is part of series, and requires that you have completed the related tutorials. Make sure you have successfully completed the required previous steps:

• Provision a {{site.data.keyword.vpc_short}} for VMware deployment

Login with IBM Cloud CLI with username and password, or use the API key. Select your target region and your preferred resource group.

The used variables e.g. $VMWARE_VPC_CRN are defined in the previous steps of this tutorial. {: note}

Provision IBM Cloud DNS service

{: #vpc-bm-vmware-dns-provision} {: step}

1. Create the DNS service using the standard-dns plan and get its ID.

   VMWARE_DNS=$(ibmcloud dns instance-create dns-vmware standard-dns --output json | jq -r .id)

   {: codeblock}

2. Set the DNS as a default DNS target.

   ibmcloud dns instance-target $VMWARE_DNS

   {: codeblock}

Provision a Zone

{: #vpc-bm-vmware-dns-zone} {: step}

1. Provision a zone. In this example vmware.ibmcloud.local is used, but you may modify this to fit your needs.

   VMWARE_DNS_ZONE_NAME=vmware.ibmcloud.local

   {: codeblock}

   VMWARE_DNS_ZONE=$(ibmcloud dns zone-create $VMWARE_DNS_ZONE_NAME -d "Zone for VMware on VPC" --output json | jq -r .id)

   {: codeblock}

2. Add your previously created {{site.data.keyword.vpc_short}} in the permitted networks. Use the {{site.data.keyword.vpc_short}} CRN here.

   ibmcloud dns permitted-network-add $VMWARE_DNS_ZONE --vpc-crn $VMWARE_VPC_CRN

   {: codeblock}

Creating DNS records

{: #vpc-bm-vmware-dns-record} {: step}

DNS records for the ESXi hosts will be created after they will be provisioned in the next tutorial following the commands provided below. {: note}

1. To create DNS records via CLI, the following command provides a help for record creation.

   ibmcloud dns resource-record-create --help

   {: codeblock}

2. To create A records for your previously created Zone vmware.ibmcloud.local, you can use the following CLI command (modify the 'NAME' and 'IP_ADDRESS' accordingly):

   ibmcloud dns resource-record-create $VMWARE_DNS_ZONE --type A --name NAME --ipv4 IP_ADDRESS

   {: codeblock}

Validate DNS records

{: #vpc-bm-vmware-dns-validation} {: step}

1. List information about configured zones in your DNS instance dns-vmware. Use the following command.

   ibmcloud dns zones -i dns-vmware

   {: codeblock}

2. List information about configured records in your DNS instance dns-vmware and zone vmware.ibmcloud.local. Use the following command.

   ibmcloud dns resource-records $VMWARE_DNS_ZONE -i dns-vmware 

   {: codeblock}

3. Verify that you permitted your {{site.data.keyword.vpc_short}} networks to access and use the DNS service:

   ibmcloud dns permitted-networks $VMWARE_DNS_ZONE

   {: codeblock}

4. When a DNS record is created during the tutorial, validate that you get correct responses from your Windows Jump host, for example using nslookup via Windows command line.

   nslookup <hostname>

   {: codeblock}

Next steps

{: #vpc-bm-vmware-dns-next-steps}

The next step in the tutorial series is:

• Provision bare metal servers for VMware deployment
