Oracle Cloud Infrastructure Requirements

OCI Overview

Oracle Cloud Infrastructure (OCI) is Oracle's cloud hosting platform. It offers databases and applications that interoperate with a range of other well-known cloud technologies and addresses common regulatory requirements.

OCI Requirements prior to installation

If deploying to OCI, ensure that you have the following:

• OCI Virtual Cloud Network (VCN) (see Oracle documentation)
  • Including subnets, routing tables, internet access, etc.
  • Load balancing, WAF, etc. for ingress into Kubernetes
• OCI Kubernetes Engine (OKE)
  • OKE Cluster v1.34+
  • Network Policy Implementation (for example, Calico or VPC CNI)
  • Custom Metrics Collection Implementation - for example, Prometheus as kube-prometheus-stack and Prometheus Adapter as prometheus-adapter
  • Block storage CSI Provider
  • Shared file system CSI Provider
• OCI Database with PostgreSQL
  • PostgreSQL v14
• OCI Cache
  • Redis OSS v7
• OCI Streaming (Platform version 4.5 or earlier)
  • Kafka Compatible API
• Apache Kafka Cluster (Platform version 4.6 or later)
  • Helm Chart for Apache Kafka v3.6
• Apache ActiveMQ (on Kubernetes)
