Apigee Hybrid on GKE

This example installs Apigee hybrid in a non-prod environment on a GKE private cluster using Terraform and Ansible. The Terraform configuration deploys all the required infrastructure including a management VM used to run an ansible playbook to the actual Apigee Hybrid setup.

The diagram below depicts the architecture.

Running the blueprint

Clone this repository or open it in cloud shell, then go through the following steps to create resources:
Copy the file terraform.tfvars.sample to a file called terraform.tfvars and update the values if required.
Initialize the terraform configuration
```
terraform init
```
Apply the terraform configuration
```
terraform apply
```
Create an A record in your DNS registrar to point the environment group hostname to the public IP address returned after the terraform configuration was applied. You might need to wait some time until the certificate is provisioned.
Install Apigee hybrid using de ansible playbook that is in the ansible folder by running this command

ansible-playbook playbook.yaml -vvv

Testing the blueprint

Deploy an api proxy
```
./deploy-apiproxy.sh apis-test
```

Send a request

curl -v https://HOSTNAME/httpbin/headers
