This tutorial will walk you through how to create and configure the pipeline step for Terraform Script.
The below mentioned steps will guide the step by step workflow for Terraform Script:
On a Pipeline, add a step for ‘Terraform’ Tool type
2. Once the step tool and name is entered, click ‘Save’ button
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 G
5. On the configuration window, select/enter the details on all the fields
6. Once all the configurations are set, click on ‘Save’ button to save the pipeline step
7. Click on ‘Start Pipeline’ to start the execution of the pipeline
8. Pipeline will start and will show a blue bar with predefined message as an indication
9. Once the script is executed and successful, a green tick will appear on the step
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
16. Pipeline will start and will show a blue bar with predefined message as an indication
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’.
Output: Terraform script initialized and 3 Subnet IDs are fetched.
A Sample Terraform script from GITLAB and GITHUB and its workflow has been demonstrated above, which in the same way can be used to invoke any possible Terraform script.
