Oracle Cloud Infrastructure: A DevOps Perspective

As a DevOps engineer at Oracle, I've had the opportunity to work extensively with Oracle Cloud Infrastructure (OCI). In this post, I'll share insights and best practices for leveraging OCI in your DevOps workflows.

OCI Overview

Oracle Cloud Infrastructure is Oracle's cloud computing platform that provides a range of services for computing, storage, networking, databases, and more. What sets OCI apart from other cloud providers is its focus on enterprise workloads, performance, and security.

Key OCI Services for DevOps

Compute

OCI offers various compute options:

Virtual Machine (VM) instances: Standard cloud VMs with flexible shapes
Bare Metal instances: Physical servers without virtualization overhead
Container Engine for Kubernetes (OKE): Managed Kubernetes service
Functions: Serverless compute (FaaS)

For DevOps workflows, OKE is particularly valuable as it provides a managed Kubernetes environment that integrates well with other OCI services.

Storage

OCI's storage options include:

Object Storage: For unstructured data like logs, backups, and artifacts
Block Volumes: Persistent block storage for VMs
File Storage: Shared file systems accessible from multiple instances

In our CI/CD pipelines, we use Object Storage extensively for storing build artifacts, Docker images, and backup data.

Developer Services

OCI provides several services specifically designed for DevOps:

DevOps service: Manages CI/CD pipelines
Artifact Registry: Stores and manages build artifacts
Resource Manager: Infrastructure as Code using Terraform
Logging: Centralized log management
Monitoring: Metrics collection and alerting

Setting Up a CI/CD Pipeline in OCI

Let's walk through setting up a basic CI/CD pipeline using OCI DevOps service:

1. Create a DevOps Project

First, create a DevOps project to organize your resources:

oci devops project create \
  --compartment-id <compartment_id> \
  --name "MyProject" \
  --description "My DevOps Project"
