This submodule defines the infrastructure needed to deploy an Elastic Search based data backend, within the context of Open Targets Platform.
The picture above these lines represents a deployment unit of Open Targets Platform Elastic Search data backend.
VM instances running the Elastic Search services are configured in a regional instance group, deployed in the given region, behind an internal load balancer.
The module can be sourced from its GitHub URL as shown below.
// --- Elastic Search Backend --- //
module "backend_elastic_search" {
source = "github.com/opentargets/terraform-google-opentargets-platform//modules/elasticsearch"
// ...
}The module implements the following input parameters.
module_wide_prefix_scope, the prefix provided here will scope names for those resources created by this module, default 'otpdeves'.
network_name, name of the network where resources should be deployed, 'default'.
network_self_link, self link to the network where resources should be connected when deployed.
network_subnet_name, name of the subnet, within the 'network_name', and the given region, where instances should be connected to.
network_source_ranges, CIDR that represents which IPs we want to grant access to the deployed resources, default '10.0.0.0/9'.
network_sources_health_checks, source CIDR for health checks, default '[ 130.211.0.0/22, 35.191.0.0/16 ]', which is the CIDRs used by Google Cloud Infrastructure.
deployment_region, region where resources should be deployed.
deployment_target_size, initial Elastic Search node count to deploy, default is '1'.
vm_firewall_tags, additional tags that should be attached to any Elastic Search Node deployed by this module.
vm_elastic_search_version, elastic Search Docker Image version to use.
vm_elastic_search_vcpus, CPU count for each Elastic Search Node VM.
vm_elastic_search_mem, amount of memory assigned to every Elastic Search Instance (MiB).
vm_elastic_search_image, VM Image to use for Elastic Search instances.
vm_elastic_search_image_project, ID of hosting project for the Elastic Search VM Instance image.
vm_elastic_search_boot_disk_size, Elastic Search instances boot disk size, default '500GB'
Once the infrastructure has been successfully deployed, the following details are revealed by this module as output.
deployment_region, region where resources have been deployed.
network_name, VPC network where resources have been connected to.
network_subnet_name, VPC Subnet within the given region where resources have been connected to.
ilb_ip_address, IP address of the deployed Internal Load Balancer that is at front of the Elastic Search VMs.
port_elastic_search_requests, Elastic Search Request port.
port_elastic_search_requests_name, named port corresponding to Elastic Search Request port.
port_elastic_search_comms, Elastic Search inter-node communications port.
port_elastic_search_comms_name, named port corresponding to Elastic Search inter-node communications port.
Infrastructure visual diagrams use AWS icons and visual elements, but their meaning in Open Targets Google Cloud Infrastructure is the same, from the conceptual point of view.
