| # External HTTPS Load Balancer with dynamic backends | ||
|
|
||
| [](https://console.cloud.google.com/cloudshell/open?git_repo=https://github.com/GoogleCloudPlatform/terraform-google-lb-http&working_dir=examples/dynamic-backend&page=shell&tutorial=README.md) | ||
|
|
||
| This creates an external Envoy-based HTTPS Load Balancer using dynamic | ||
| backends suitable for integrating with a Google Kubernetes Engine cluster | ||
| running [gke-autoneg-controller](https://github.com/GoogleCloudPlatform/gke-autoneg-controller). | ||
| The load balancer will not route traffic to any backend service or bucket; | ||
| instead, it expects that an external user or service will register backends | ||
| (such as Network Endpoint Groups) accordingly to serve traffic. The example | ||
| will attempt to provision a Google-managed TLS certificate for the domain | ||
| "example.com" by default and use `/api/health` as a health check endpoint. | ||
|
|
||
| ## Change to the example directory | ||
|
|
||
| ``` | ||
| [[ `basename $PWD` != https-gke ]] && cd examples/dynamic-backend | ||
| ``` | ||
|
|
||
| ## Install Terraform | ||
|
|
||
| 1. Install Terraform if it is not already installed (visit [terraform.io](https://terraform.io) for other distributions): | ||
|
|
||
| ## Set up the environment | ||
|
|
||
| 1. Set the project, replace `YOUR_PROJECT` with your project ID: | ||
|
|
||
| ``` | ||
| PROJECT=YOUR_PROJECT | ||
| ``` | ||
|
|
||
| ``` | ||
| gcloud config set project ${PROJECT} | ||
| ``` | ||
|
|
||
| 2. Configure the environment for Terraform: | ||
|
|
||
| ``` | ||
| [[ $CLOUD_SHELL ]] || gcloud auth application-default login | ||
| export GOOGLE_PROJECT=$(gcloud config get-value project) | ||
| ``` | ||
|
|
||
| 3. Create the dynamic backend load balancer. | ||
|
|
||
| ``` | ||
| ( | ||
| cd dynamic-backend/ | ||
| terraform init | ||
| terraform plan -out terraform.tfplan | ||
| terraform apply terraform.tfplan | ||
| ) | ||
| ``` | ||
|
|
||
| 4. Deploy the `gke-autoneg-controller` into a GKE cluster and configure it according to the instructions. This will create a Network Endpoint Group for a service and bind it to this load balancer. | ||
|
|
||
|
|
||
| ## Cleanup | ||
|
|
||
| 1. Delete the load balancing resources created by terraform: | ||
|
|
||
| ``` | ||
| terraform destroy | ||
| ``` | ||
|
|
