Invoke Terraform Scripts

Use specific commands to invoke the terraform scripts in Oracle WebLogic Server for OKE.

Topics:

• Invoke terraform scripts in an infrastructure
• Update an infrastructure
• Destroy an infrastructure

The following section reference files in the input directory that you need create. Depending on the type of stack (JRF or non-JRF), create the appropriate files in the inputs directory. For information about the input files, see Sample Scripts.

To invoke terraform scripts in an infrastructure:

Complete the following steps:

1. Go to the directory, where you unzipped the terraform configuration files.
2. Initialize the terraform provider plugin:

   $ terraform init

3. Initialize the environment with terraform environment var files:

   $ source inputs/env_vars

4. Invoke apply passing all *.tfvars files as input:

   Tip:

   If you do not specify the -var-file, then the defaults in vars.tf will apply.
   • WebLogic Non-JRF:

     $ terraform apply -var-file=inputs/instance.tfvars

   • WebLogic JRF with OCI database:

     $ terraform apply -var-file=inputs/instance.tfvars -var-file=inputs/oci_db.tfvars

   • WebLogic JRF with ATP database:

     $ terraform apply -var-file=inputs/instance.tfvars -var-file=inputs/atp_db.tfvars

5. Create multiple instances from same solutions:

   $ terraform apply -var-file=inputs/instance.tfvars -state=<file_name>

   Where, <file_name> is the unique directory name or state file name for each stack.

To update an infrastructure:

Complete the following steps:

1. Update the variables. For the list of variables you can update, see Table 1-1.
2. Complete step 1 through step 4 in Invoke terraform scripts.

To destroy an infrastructure:

$ terraform destroy -var-file=inputs/instance.tfvars

Delete the Resources and Stack

Tip:

You can invoke terraform scripts by using the Resource Manager. See Get Started with Oracle WebLogic Server for OKE and Managing Stacks and Jobs.
