Symfony_or_Drupal_Instance_with_optional_RDS_instance.template

To automate the creation of AWS resources for Symfony or Drupal websites

IMPORTANT INFORMATION

This template creates an Amazon EC2 instance and an Amazon RDS DB instance. You will be billed for the AWS resources used if you create a stack from this template.

This template has been created based on my needs and has to be customized for your usage. The elements I recommend to change are identified by these symbols: << >> in the template. The template won't work if you leave these symbols.

What this template does

It creates an AWS environment ready for a Drupal or Symfony project with a database hosted on AWS RDS.

It creates these resources:

• 1 EC2 instance

  AMI : in parameter (tested with Amazon Linux AMI)
  Type : in parameter
  Tags : in parameter
  Key : provide the name of the Amazon key pair (in parameter)
  Termination protection : true (attention! it means the stack can't be deleted before disabling the protection)
  IAM role : start the instance with a specific IAM role
  Packages : an update is performed and the packages for Drupal or Symfony projects are installed (depending on parameter)
  Web server : Apache is configured and we make sure it's running
  php.ini : set the date.timezone
  Monitoring : install the Amazon monitoring scripts and set the cron job to send Disk space and Memory data to CloudWatch

• 1 Security group for the EC2 instance

  Port 22 : open only to CIDR in parameter (ExternalIP)
  Port 80 : open only to CIDR in parameter (ExternalIP)

• 4 CloudWatch alarms for the EC2 instance

  Disk space available
  Memory utilization
  Status checks
  CPU utilization

• 1 RDS DB instance (optional)

  Engine : MySQL
  Type : db.t1.micro
  Storage : 5G
  MultiAZ : false
  MasterUser : root
  MasterPassword : in parameter

• 1 Security group for the RDS DB instance (optional)

  The EC2 instance is authorized
  The CIDR (parameter ExternalIP) is authorized

• 2 CloudWatch alarms for the RDS instance

  CPU Utilization
  Freeable Space

What this template doesn't do

• It doesn't install a database server on the EC2 instance

• It doesn't create a database on the RDS DB instance (it just creates the instance, you have to create your databases afterwards)

• It doesn't upload your code (the Drupal code should be in /var/www/<projectName>/htdocs/, the Symfony code should be in /var/www/<projectName>/web/)

• It doesn't create the IAM role

• It doesn't create the SNS topic (used for CloudWatch alarms)

• It doesn't check the length of the master password for the DB instance
