# Internal Proxy Network Load Balancer Module
|
||||
|
||||
This module allows managing Internal HTTP/HTTPS Load Balancers (L7 ILBs). It's designed to expose the full configuration of the underlying resources, and to facilitate common usage patterns by providing sensible defaults, and optionally managing prerequisite resources like health checks, instance groups, etc.
|
||||
|
||||
Due to the complexity of the underlying resources, changes to the configuration that involve recreation of resources are best applied in stages, starting by disabling the configuration in the urlmap that references the resources that need recreation, then doing the same for the backend service, etc.
|
||||

|
||||
|
||||
### Minimal Example
|
||||
|
||||
An Regional internal proxy Network Load Balancer with a backend service pointing to an existing GCE instance group:
|
||||
|
||||
```hcl
|
||||
module "tcp-proxy" {
|
||||
source = "./fabric/modules/net-lb-proxy-int"
|
||||
name = "ilb-test"
|
||||
project_id = var.project_id
|
||||
region = "europe-west1"
|
||||
backend_service_config = {
|
||||
backends = [{
|
||||
group = "projects/myprj/zones/europe-west1-a/instanceGroups/my-ig"
|
||||
}]
|
||||
}
|
||||
vpc_config = {
|
||||
network = var.vpc.self_link
|
||||
subnetwork = var.subnet.self_link
|
||||
}
|
||||
}
|
||||
# tftest modules=1 resources=4
|
||||
```
|
||||
|
||||
### Health Checks
|
||||
|
||||
You can leverage externally defined health checks for backend services, or have the module create them for you. By default a simple TCP health check on port 80 is created, and used in backend services.
|
||||
|
||||
Health check configuration is controlled via the `health_check_config` variable, which behaves in a similar way to other LB modules in this repository.
|
||||
|
||||
```hcl
|
||||
module "int-tcp-proxy" {
|
||||
source = "./fabric/modules/net-lb-proxy-int"
|
||||
name = "int-tcp-proxy"
|
||||
project_id = var.project_id
|
||||
region = "europe-west1"
|
||||
backend_service_config = {
|
||||
backends = [{
|
||||
group = "projects/myprj/zones/europe-west1-a/instanceGroups/my-ig"
|
||||
}]
|
||||
}
|
||||
health_check_config = {
|
||||
tcp = { port = 80 }
|
||||
}
|
||||
vpc_config = {
|
||||
network = var.vpc.self_link
|
||||
subnetwork = var.subnet.self_link
|
||||
}
|
||||
}
|
||||
# tftest modules=1 resources=4
|
||||
```
|
||||
|
||||
To leverage an existing health check without having the module create them, simply pass its self link:
|
||||
|
||||
```hcl
|
||||
module "int-tcp-proxy" {
|
||||
source = "./fabric/modules/net-lb-proxy-int"
|
||||
name = "int-tcp-proxy"
|
||||
project_id = var.project_id
|
||||
region = "europe-west1"
|
||||
backend_service_config = {
|
||||
backends = [{
|
||||
group = "projects/myprj/zones/europe-west1-a/instanceGroups/my-ig"
|
||||
}]
|
||||
}
|
||||
health_check = "projects/myprj/global/healthChecks/custom"
|
||||
vpc_config = {
|
||||
network = var.vpc.self_link
|
||||
subnetwork = var.subnet.self_link
|
||||
}
|
||||
}
|
||||
# tftest modules=1 resources=4
|
||||
```
|
||||
|
||||
### Instance Groups
|
||||
|
||||
The module can optionally create unmanaged instance groups, which can then be referred in backends via their key:
|
||||
|
||||
```hcl
|
||||
module "int-tcp-proxy" {
|
||||
source = "./fabric/modules/net-lb-proxy-int"
|
||||
name = "int-tcp-proxy"
|
||||
project_id = var.project_id
|
||||
region = "europe-west1"
|
||||
backend_service_config = {
|
||||
port_name = "http"
|
||||
backends = [
|
||||
{ group = "default" }
|
||||
]
|
||||
}
|
||||
group_configs = {
|
||||
default = {
|
||||
zone = "europe-west1-b"
|
||||
instances = [
|
||||
"projects/myprj/zones/europe-west1-b/instances/vm-a"
|
||||
]
|
||||
named_ports = { http = 80 }
|
||||
}
|
||||
}
|
||||
vpc_config = {
|
||||
network = var.vpc.self_link
|
||||
subnetwork = var.subnet.self_link
|
||||
}
|
||||
}
|
||||
# tftest modules=1 resources=5
|
||||
```
|
||||
|
||||
### Network Endpoint Groups (NEGs)
|
||||
|
||||
Network Endpoint Groups (NEGs) can be used as backends, by passing their id as the backend group:
|
||||
|
||||
```hcl
|
||||
module "int-tcp-proxy" {
|
||||
source = "./fabric/modules/net-lb-proxy-int"
|
||||
name = "int-tcp-proxy"
|
||||
project_id = var.project_id
|
||||
region = "europe-west1"
|
||||
backend_service_config = {
|
||||
backends = [{
|
||||
group = "projects/myprj/zones/europe-west1-a/networkEndpointGroups/my-neg"
|
||||
}]
|
||||
}
|
||||
vpc_config = {
|
||||
network = var.vpc.self_link
|
||||
subnetwork = var.subnet.self_link
|
||||
}
|
||||
}
|
||||
# tftest modules=1 resources=4
|
||||
```
|
||||
|
||||
Similarly to instance groups, NEGs can also be managed by this module which supports GCE, hybrid and Private Service Connect NEGs:
|
||||
|
||||
#### Zonal NEG creation
|
||||
|
||||
```hcl
|
||||
resource "google_compute_address" "test" {
|
||||
name = "neg-test"
|
||||
subnetwork = var.subnet.self_link
|
||||
address_type = "INTERNAL"
|
||||
address = "10.0.0.10"
|
||||
region = "europe-west1"
|
||||
}
|
||||
|
||||
module "int-tcp-proxy" {
|
||||
source = "./fabric/modules/net-lb-proxy-int"
|
||||
name = "int-tcp-proxy"
|
||||
project_id = var.project_id
|
||||
region = "europe-west1"
|
||||
backend_service_config = {
|
||||
backends = [{
|
||||
group = "my-neg"
|
||||
balancing_mode = "CONNECTION"
|
||||
max_connections = {
|
||||
per_endpoint = 10
|
||||
}
|
||||
}]
|
||||
}
|
||||
neg_configs = {
|
||||
my-neg = {
|
||||
gce = {
|
||||
zone = "europe-west1-b"
|
||||
endpoints = {
|
||||
e-0 = {
|
||||
instance = "test-1"
|
||||
ip_address = google_compute_address.test.address
|
||||
# ip_address = "10.0.0.10"
|
||||
port = 80
|
||||
}
|
||||
}
|
||||
}
|
||||
}
|
||||
}
|
||||
vpc_config = {
|
||||
network = var.vpc.self_link
|
||||
subnetwork = var.subnet.self_link
|
||||
}
|
||||
}
|
||||
# tftest modules=1 resources=7
|
||||
```
|
||||
|
||||
#### Hybrid NEG creation
|
||||
|
||||
```hcl
|
||||
module "int-tcp-proxy" {
|
||||
source = "./fabric/modules/net-lb-proxy-int"
|
||||
name = "int-tcp-proxy"
|
||||
project_id = var.project_id
|
||||
region = "europe-west1"
|
||||
backend_service_config = {
|
||||
backends = [{
|
||||
group = "my-neg"
|
||||
balancing_mode = "CONNECTION"
|
||||
max_connections = {
|
||||
per_endpoint = 10
|
||||
}
|
||||
}]
|
||||
}
|
||||
neg_configs = {
|
||||
my-neg = {
|
||||
hybrid = {
|
||||
zone = "europe-west1-b"
|
||||
endpoints = {
|
||||
e-0 = {
|
||||
ip_address = "10.0.0.10"
|
||||
port = 80
|
||||
}
|
||||
}
|
||||
}
|
||||
}
|
||||
}
|
||||
vpc_config = {
|
||||
network = var.vpc.self_link
|
||||
subnetwork = var.subnet.self_link
|
||||
}
|
||||
}
|
||||
# tftest modules=1 resources=6
|
||||
```
|
||||
|
||||
#### Private Service Connect NEG creation
|
||||
|
||||
```hcl
|
||||
module "int-tcp-proxy" {
|
||||
source = "./fabric/modules/net-lb-proxy-int"
|
||||
name = "int-tcp-proxy"
|
||||
project_id = var.project_id
|
||||
region = "europe-west1"
|
||||
backend_service_config = {
|
||||
backends = [{
|
||||
group = "my-neg"
|
||||
balancing_mode = "CONNECTION"
|
||||
max_connections = {
|
||||
per_endpoint = 10
|
||||
}
|
||||
}]
|
||||
}
|
||||
neg_configs = {
|

my-neg = {
|

psc = {
|

region = "europe-west1"
|

target_service = "europe-west1-cloudkms.googleapis.com"
|

}
|

}
|

}
|

vpc_config = {

network = var.vpc.self_link
|

subnetwork = var.subnet.self_link
|

}
|

}
