Cloud Resources Creation

Once the infrastructure file has been created we can to proceed with cloud resources creation:

  1. We can attempt to setup a compatable version of Terraform. This directory will be inside of ~/.edb-terraform/bin Logs can be found inside of ~/.edb-terraform/logs

    $ edb-terraform setup

  2. A new Terraform project must be created with the help of the edb-terraform script. This script is in charge of creating a dedicated directory for the project, generating SSH keys, building Terraform configuration based on the infrastructure file, copying Terraform modules into the project directory.

    a. First argument is the project path, second argument is the path to the infrastructure file

    Use option -c to specify the cloud provider option: azure aws gcloud

    Defaults to aws if not used

    $ edb-terraform generate --project-name aws-terraform \
                         --cloud-service-provider aws \
                         --infra-file edb-terraform/infrastructure-examples/aws/edb-ra-3.yml \
                         --user-templates edb-terraform/infrastructure-examples/templates/inventory.yml.tftpl

    b. Step 2 can be skipped if option --validate is included with generate, which provides basic validations and checks through terraform.

  1. Terraform initialisation of the project:

    $ cd aws-terraform
$ terraform init

  2. Apply Cloud resources creation:

    $ cd aws-terraform
$ terraform apply -auto-approve

Customizations

Users can further modify their resources after the initial provisioning. If any output files are needed based on the resources, terraform templates can be added to the projects template directory to have it rendered with any resource outputs once all resources are created. Examples of template files can be found here: edb-ansible included inventory.yml sample inventory.yml

Cloud resources destruction
