Terraform module to create AWS Spot instances for various purposes.

The module provide the following profiles:

• ECS node
• Common node

• name - project information, used for tags and unique iam role name
• subnet_id - placement subnet
• security_group_id - placement security group

• ssh_key - default ssh pair id
• capacity - amount of nodes (default 1)
• type - type of launch configuration (default is common_node, currently supported values are common_node & ecs_node)
• common_node_ami_id - AMI image used for common_node type of launch configuration (default is the most recent Amazon provided AMI)
• ecs_node_ami_id - AMI image used for ecs_node type of launch configuration (default is the most recent Amazon provided AMI)
• iam_instance_profile - IAM instance profile arn (required for ECS node, default is empty value)
• ec2_type - AWS EC2 type (default t2.small)
• userdata - userdata script body (default is empty value)
• disk_size_root - size of instance root partition (default is 8Gb)
• disk_size_docker - size of instance docker partition, used for ecs_node type (default is 25Gb)
• valid_until - the date until spot request is valid (default 2033-01-01T01:00:00Z)
• public_ip - assign public IP on EC2 node (default false)
• internet_access - allow access to internet (default true)

Example: One linux box

module "bastion_host" {
    source               = ""
    name                 = "Bastion host"
    subnet_id            = "${aws_subnet.default.id}"
    ssh_key              = "${aws_key_pair.default.id}"
    security_group_ids   = ["${aws_security_group.myecs.id}"]
}

Example: Five ECS nodes of c5.large type

module "my_ecs_nodes" {
    source                   = "github.com/jetbrains-infra/terraform-aws-spot-fleet"
    name                     = "Example ECS cluster"
    subnet_id                = "${aws_subnet.default.id}"
    security_group_ids       = ["${aws_security_group.myecs.id}"]
    iam_instance_profile_arn = "${aws_iam_instance_profile.ecs_node.arn}" // wtf
    capacity                 = "5"
    type                     = "ecs_node" // currently supported values are "common_node" & "ecs_node"
    ec2_type                 = "c5.large"
    userdata                 = <<EOT
#!/bin/bash
echo ECS_CLUSTER="${aws_ecs_cluster.example.name}" >> /etc/ecs/ecs.config
