COA DevOps Training UseCase.

-- How to build a pipeline with OCI DevOps --

This example creates an Autonomous Database (JSON) exposed to the public Internet.

✅ Showcase

During this UseCase we're going to:

• Use OCI DevOps service.
• Configure a CI/CD pipeline.
• Use OCI S3 as a backed for terraform.
• Use OCI Vault for storing sensitive information.
• Deploy IaC using Terraform, in this case an ADB resource.

✅ Usage

• Create an object storage bucket called "terraform-backend".
• We want to use a S3-Compatible Backend , read the documentation carefully.
• Create a "Customer Secret keys" also named as "Amazon S3 Compatibility API keys". A Customer Secret key consists of an Access Key/Secret key pair.
• Declare the below variables to OCI vault as secrets

aws_access_key_id 
aws_secret_access_key 
user_ocid
fingerprint

• Clone this repo in OraHub, GitLab or GitHub and create you own DevOps repository.

• Fill the correct OCID values of secrets in file build_spec.yaml

• Add your api_private_key to the file user.pem

• Rename the file terraform.tfvars.template to terraform.tfvars and add the values of your tenancy_ocid and compartment_ocid

• Define the values of your region and adb_password in the file adb.auto.tfvars

• Define the values of your region and namespace in the file remote_backend.tf

• Create a OCI DevOps Project

• Review OCI documentation and add the required DG and policies.

• Configure a code repository in DevOps to mirror the repository you have created in the previous step.

• Create a build pipeline and create a manage build.

• Enable logging.

• Run the build pipeline manually and review the implementation.

• Check that now you can see the database provisioned in your compartment.

• If you have arrived at this point with a successful outcome, you can add a trigger to lunch the pipeline automatically after any push action to your repository.

• Remove manually (using OCI Console) the ADB created previously.
• Change you repo code, for example change the ADB name, and push the changes.
• Review the outcome:
