3-networks-extension

This is an additional Terraform configuration for example-foundation 3-Networks and is used to set up the subnets, additional firewall rules for the Bank of Anthos example application across dev/non-prod/prod environments.

Prerequisites

  1. 0-bootstrap executed successfully.
  2. 1-org executed successfully.
  3. 2-environments/envs/ executed successfully.

Order of Execution

Clone 3-networks from example-foundation

  • Run the bash script network_prepare.sh using either cd ../../ && make docker_network_prepare or execute script directly in this folder ./network_prepare.sh
  • Alternatively you can perform the steps of the bash script manually laid out in the next section

After cloning 3-networks from example-foundation

  • Follow steps in example_foundation 3-Networks, interchanging the paths
    • terraform-example-foundation/3-networks with terraform-example-foundation-app/foundation-extension/3-networks
    • terraform-example-foundation/build with terraform-example-foundation-app/build

Steps performed in bash script

  1. Clone example_foundation 3-Networks
  2. Merge files from 3-networks-extensions/envs into 3-networks/envs for the respective environments
  3. Copy cloudbuild-tf-* and tf-wrapper.sh files from example-foundation/build to the build folder in the root of this repo.
  4. Change Primary Region in example_foundation 3-networks/common.auto.tfvars from us-central1 to us-east1 to be consistent with BOA 4-projects and 5-infrastructure
  5. Remove Base Shared VPC defined in main.tf of example_foundation 3-Networks as boa_vpc_fw.tf replaces it with new subnets.

Local Run Troubleshooting

  1. Ensure you have given execute permissions chmod +x network_prepare.sh
  2. If you get '\r Error' you can use dos2unix to convert file format "dos2unix network_prepare.sh", you may need to install dos2unix first
