How to use

You can build wordpress by following process. But if you want to operate wordpress in production, you need to configure more.

$ cp terraform.tfvars.sample terraform.tfvars
$ vim terraform.tfvars 
  => Edit variables with your favorite editor.

// Deploy to Alibaba Cloud
$ terraform apply
...
Apply complete! Resources: 12 added, 0 changed, 0 destroyed.

Outputs:
rds_connection_string = xxxxxxxxx.rds.aliyuncs.com
wordpress_eip = xx.xx.xx.xx

// Connect to ECS instance with ssh
$ ssh ecs-user@xx.xx.xx.xx

// Configure wordpress
$ cd /var/www/html/wordpress
$ sudo cp wp-config-sample.php wp-config.php
$ sudo vim wp-config.php
define('DB_NAME', 'database_name_here');
define('DB_USER', 'username_here');
define('DB_PASSWORD', 'password_here');
define('DB_HOST', 'localhost');
