3. Identify the Terraform script available in Git Repository.
Scenario-1: Having AWS Credentials - Static on the Terraform script as shown below
In the below example, we have the Terraform script available at ‘python-example > Terraform > Terraform > subnet.tf’
...
4. On pipeline, Terraform script step → Click on the ‘Configuration’ icon to enter step level configuration to invoke Terraform script run in GitlabG
...
5. On the configuration window, select/enter the details on all the fields
...
10. The script success can be tracked in the Summary tab > Activity logs as well
...
11. Output of the script is given below - where the Terraform script is meant to fetch the Subnet IDs of the VPC given as ‘Terraform script argument’.
Output: Terraform script initialized and 3 Subnet IDs are fetched.
...
Scenario-2: Having AWS Credentials - Dynamic on the Terraform script as shown below
In the below example, we have the Terraform script available at ‘python-example > Terraform > Terraform > subnet.tf’
...
12. On pipeline, Terraform script step → Click on the ‘Configuration’ icon to enter step level configuration to invoke Terraform script run from GITHUB REPOSITORY
...
13. On the configuration window, select/enter the details on all the fields
...
14. Once all the configurations are set, click on ‘Save’ button to save the pipeline step
...
15. Click on ‘Start Pipeline’ to start the execution of the pipeline

17. Once the script is executed and successful, a green tick will appear on the step
...
18. The script success can be tracked in the Summary tab > Activity logs as well
...
19. Output of the script is given below - where the Terraform script is meant to fetch the Subnet IDs of the VPC given as ‘Terraform script argument’.
