Changing directory to the editable folder

cd anthos-on-aws-terraform/vpc

Editable section

• backend.tf file - Definition of your terraform code backend, where all the statefiles gonna save

sample image

• terraform.tfvars.sample - Definition of values of each variable present in the terraform code,before apply make sure rename the file to terraform.tfvars

sample image

Applying the configuration

1 Download the required modules

terraform init

2. Validate the deployments

terraform plan

3. Deploy the ASM to our existing cluster

terraform apply
