Terragrunt code example for multiple target infra environments.

To provision all environments, just run command below on the root project directory:

terragrunt run-all init
terragrunt run-all plan
terragrunt run-all apply

Below are steps to provision infra-one only.

To provision both dev and prod, can run command below:

cd infra-one/
terragrunt run-all init
terragrunt run-all plan
terragrunt run-all apply

To provision only dev, can run command below:

cd infra-one/dev/
terragrunt init
terragrunt plan
terragrunt apply

To provision only prod, can run command below:

cd infra-one/prod/
terragrunt init
terragrunt plan
terragrunt apply

Below are steps to provision infra-two only.

To provision both dev and prod, can run command below:

cd infra-two/
terragrunt run-all init
terragrunt run-all plan
terragrunt run-all apply

To provision only dev, can run command below:

cd infra-two/dev/
terragrunt init
terragrunt plan
terragrunt apply

To provision only prod, can run command below:

cd infra-two/prod/
terragrunt init
terragrunt plan
terragrunt apply

Note: both infra-one and infra-two will produce the same infrastructure, they only use different code style
