Introduction
Manual setup is fine for a single instance — but when you’re managing multiple networks, compute nodes, and databases, automation becomes essential. OCI provides powerful tools like the Command Line Interface (CLI) and Terraform to simplify and replicate deployments.
OCI CLI – Your Command-Line Control Center
The OCI CLI lets you interact with your environment using scripts or terminal commands.
Installation
Example Commands
Use CLI for scripting, monitoring, and quick automation tasks.
Terraform – Infrastructure as Code
Terraform automates full infrastructure builds using declarative templates.
A simple example:
Run:
Your network appears automatically.
Automation Best Practices
-
Keep your Terraform scripts in Git for version control
-
Use variables.tf for environment customization
-
Encrypt credentials with Vault or OCI secrets
-
Validate templates before deployment
Conclusion
Using OCI CLI and Terraform, you can deploy complex architectures consistently and repeatably — no manual clicks required.
