Deployment

Use Terraform to deploy the example setup.

1. Set the required Terraform variables

   variables.tf

2. Deploy the example infrastructure

   cd terraform
   terraform init
   terraform apply

3. Try it for yourself

   Log in to the client VM:

   gcloud compute ssh client --tunnel-through-iap --project <project_id>

   Invoke a service in the destination VPC:

   curl -x http://proxy.xebia:3128 http://example-server.xebia/

   Invoke an internet url via the proxy:

   curl -x http://proxy.xebia:3128 https://www.google.com/

Clean up

Use Terraform to destroy the example setup.

1. Set the required Terraform variables

   variables.tf

2. Destroy the example infrastructure

   cd terraform
   terraform init
   terraform destroy
