A project to set up infrastructure in AWS for an Apache Cassandra cluster. This module will create Cassandra on EC2 and auto-cluster all of its nodes.
It's 100% Open Source and licensed under the APACHE2.
The folder example/examplea contains a complete sample illustration of how to use this module.

│ examplea.auto.tfvars
│ Makefile
│ module.cassandra.tf
│ outputs.tf
│ provider.aws.tf
│ variables.tf
As a minimum you must include a module reference in your own template Terraform code e.g. module.cassandra.tf:
module "cassandra" {
source = "JamesWoolfenden/cassandra/aws"
version = "0.3.1"
instance_type = var.instance_type
subnet_ids = data.aws_subnet_ids.subs.ids
#add the private ips
private_ips = []
allowed_ranges = [module.myip.cidr]
ssh-inbound-range = [module.myip.cidr]
ami = local.ami
vpc_id = tolist(data.aws_vpcs.main.ids)[0]
}You will also need to define variables variables.tf and supply values examplea.auto.tfvars. You'll need to adjust the values to your own. You will also need build a Cassandra AMI, see the Packer folder for that template. If you want to test the modules usage execute Terraform in the examplea folder:
cd example/examplea

Terraform has been successfully initialized!
You may now begin working with Terraform. Try running "terraform plan" to see
any changes that are required for your infrastructure. All Terraform commands
should now work.
If you ever set or change modules or backend configuration for Terraform,
rerun this command to reinitialize your working directory. If you forget, other
commands will detect it and remind you to do so if necessary.
