Terraform code to provision AWS infra and deploy Joomla app.

The infra resources as per below:
VPC and related network and security (i.e. SG, subnets, net CIDR etc)
Autoscaling group
Application Load Balancer (HTTP/80 listener only)
CloudWatch metrics alarm (HTTP status 4xx count)
SNS for notification about the previous alarm
RDS/mySQL DB service

vpc_name = "vpc_claranet"
vpc_region = "eu-west-1"
vpc_cidr = "10.0.0.0/16"
vpc_private_subs = ["10.0.101.0/24", "10.0.102.0/24"]
vpc_public_subs = ["10.0.1.0/24", "10.0.2.0/24"]
image_id = "ami-0943382e114f188e8"
instance_type = "t2.micro"
asg_min_size = 1
asg_max_size = 3
email = "[email protected]"
db_name = "joomla_db"
db_user = "joomla"
db_passwd = "Joomla_123"
db_engine = "mysql"
db_engine_ver = "8.0.23"
db_class = "db.m6g.large"

Here you'll find a bash script which will install LAMP (without mysql as a separate RDS service will be provisioned), will install Joomla (you will also find the "ver" variable should you need to install other versions) and logrotate conf for the Apache2 logs.

terraform init
terraform plan
terraform apply
