Creating a WordPress website using Terraform

To create and set up a WordPress website using Terraform:

1. Prepare your cloud.
2. Create an infrastructure.
3. Configure WordPress.

If you no longer need the resources you created, delete them.

Prepare your cloudPrepare your cloud

Sign up for Yandex Cloud and create a billing account:

1. Go to the management console and log in to Yandex Cloud or create an account if you do not have one yet.
2. On the Yandex Cloud Billing page, make sure you have a billing account linked and it has the ACTIVE or TRIAL_ACTIVE status. If you do not have a billing account, create one.

If you have an active billing account, you can go to the cloud page to create or select a folder for your infrastructure to operate in.

Learn more about clouds and folders.

Make sure the selected folder has a cloud network with a subnet in at least one availability zone. To do this, select VPC on the folder page. If the list contains a network, click its name to see the list of subnets. If the subnets or network you need are not listed, create them.

Required paid resourcesRequired paid resources

The cost of hosting a website in WordPress includes:

• Fee for a continuously running VM (see Yandex Compute Cloud pricing).
• Fee for using a dynamic or static public IP address (see Yandex Virtual Private Cloud pricing).
• Fee for public DNS queries and DNS zones if using Yandex Cloud DNS (see Cloud DNS pricing).

Create an infrastructureCreate an infrastructure

Terraform allows you to quickly create a cloud infrastructure in Yandex Cloud and manage it using configuration files. Configuration files store the infrastructure description in the HashiCorp Configuration Language (HCL). Terraform and its providers are distributed under the Business Source License.

For more information about the provider resources, see the documentation on the Terraform website or the mirror.

If you change the configuration files, Terraform automatically detects which part of your configuration is already deployed, and what should be added or removed.

To create an infrastructure using Terraform:

1. Install Terraform, get the authentication credentials, and specify the source for installing the Yandex Cloud provider (see Configure a provider, step 1).

2. Prepare files with the infrastructure description.

   Ready-made archive

   Manually

   1. Create a directory for files.
   2. Download the archive (1 KB).
   3. Unpack the archive to the directory. The wordpress.tf file should be added to the directory.

   1. Create a directory for files.

   2. Create the wordpress.tf configuration file in the directory:

      wordpress.tf

   For more information about the parameters of resources used in Terraform, see the provider documentation:

   • VM instance: yandex_compute_instance
   • Security groups: yandex_vpc_security_group
   • Network: yandex_vpc_network
   • Subnets: yandex_vpc_subnet
   • DNS zone: yandex_dns_zone
   • DNS resource record: yandex_dns_recordset

3. Under metadata, enter the metadata for creating a VM instance: <username>:<SSH_key_contents>. Regardless of the username specified, the key is assigned to the user set in the WordPress image configuration. Such users vary depending on an image. For more information, see Keys processed in public images.

4. Create resources:

   1. In the terminal, change to the folder where you edited the configuration file.

   2. Make sure the configuration file is correct using the command:

      terraform validate
      

      If the configuration is correct, the following message is returned:

      Success! The configuration is valid.
      

   3. Run the command:

      terraform plan
      

      The terminal will display a list of resources with parameters. No changes are made at this step. If the configuration contains errors, Terraform will point them out.

   4. Apply the configuration changes:

      terraform apply
      

   5. Confirm the changes: type yes in the terminal and press Enter.
