This repository contains the Terraform module for creating a simple but ready-to-use Kubernetes Cluster on Oracle Container Engine for Kubernetes (OKE).
It uses the latest available Kubernetes version available in the Oracle Cloud Infrastructure region and creates a kubeconfig file at completion.
You need an Oracle Cloud account.
- Always uses latest Kubernetes version available at Oracle Cloud
- kubeconfig file generation
- Creates separate node pool for worker nodes
- Allows SSH access from workstation IPv4 address only
export KUBECONFIG=./kubeconfig_oci
in repo root dir to use the generated kubeconfig file- The
enable_oracle
variable is used in the hajowieland/terraform-kubernetes-multi-cloud module - It can take a few minutes after Terraform finishes until the Kubernetes nodes are available!
See tables at the end for a comprehensive list of inputs and outputs.
- Default region: eu-frankfurt-1 (Frankfurt, Germany)
- Default worker node type: VM.Standard2.1 (1x vCPU, 15.0GB memory)
- Default worker node pool size: 2 (per subnet, by default we only use one subnet)
