Examples for testing dual-stack changes to terraform module terraform-google-lb-http

These examples are copied from the main terraform-google-lb-http repo.

However, their source module is set to my own changes from issue-112-dual-stack branch. Idea is to exactly test the changes as requested in this issue comment.

Structure

There are 2 cases to be verified for IPv6 address changes - as outlined in the discussion thread:

1. new automatically allocated IPv6 address (folder: new_ipv6)
2. pre-created IPv6 address (either EIP in GCP or bring-your-own-address) (folder: precreated_ipv6)

I have also included exact changes I made to the https-redirect example in the corresponding .diff files.

The output from terraform commands is included in some .txt files in the respective example directories.

How to run

To run the examples, change into the corresponding directory, edit the values in test.tfvars file (mainly, project id, region, zone and network_name) and run following commands:

$ terraform init
$ terraform plan -var-file=test.tfvars # to see the changes before applying them
$ terraform apply -var-file=test.tfvars # to finally apply the changes.

To destroy the infra created, run:

$ terraform destroy -var-file=test.tfvars
