Yes, Terraform can do that: SQL

This post is going to be the first in a new collection of posts about what you can do with Terraform. I am continually learning about new things to use Terraform to accomplish. Most of these have naturally been things that I have needed to do that have helped me discover these options, and the others will be things that I just found interesting. Let’s start diving into Terraforming SQL.

Terraform has two databases listed on their providers, the two are PostgreSQL and MySQL. Both of these providers focus on more administration tasks, which makes sense given how you typically use Terraform. I am going to be grabbing a Docker image for MySQL to use to execute the Terraform.

$ docker run --name mysql -e MYSQL_ROOT_PASSWORD=6Fg4GBVcdI6U -e MYSQL_ROOT_HOST=% -p 3306:3306 -d mysql
....
....
2020-03-15T00:39:44.847890Z 0 [System] [MY-010931] [Server] /usr/sbin/mysqld: ready for connections. Version: '8.0.19'  socket: '/var/run/mysqld/mysqld.sock'  port: 3306  MySQL Community Server - GPL.
2020-03-15T00:39:45.006311Z 0 [System] [MY-011323] [Server] X Plugin ready for connections. Socket: '/var/run/mysqld/mysqlx.sock' bind-address: '::' port: 33060

Now create your main.tf and add the following.

provider "mysql" {
  endpoint = "172.17.0.1:3306"
  username = "root"
  password = "6Fg4GBVcdI6U"
}

resource "mysql_database" "petdb" {
  name = "petdb"
}

Now we can execute this to create our database.

$ terraform init
$ terraform apply
mysql_database.petdb: Creating...
mysql_database.petdb: Creation complete after 0s [id=petdb]

That’s it, and now you can combine this with a cloud provider to bootstrap your databases in your templates.

Thanks for reading,
