Details

Oracle Cloud Native Environment is a fully integrated suite for developing and managing cloud-native applications. The core module is the Kubernetes module. It deploys and manages containers and automatically installs and configures CRI-O, runC, and Kata Containers. CRI-O manages the container runtime for a Kubernetes cluster, which may be either runC or Kata Containers.

Oracle Cloud Native Environment Release 1.5.7 introduced the ability to use the Oracle Cloud Native Environment Platform CLI to perform a quick installation of itself. The installation runs using the olcnectl provision command on an installation host (the operator node). The olcnectl provision command can perform the following operations on the target nodes:

  • Generate CA Certificates. (This tutorial uses private CA Certificates. It is recommended for a production environment that you use your own CA Certificates.)
  • Copy the CA Certificates to each node.
  • Set up the operating system on each node, including the network ports.
  • Install the Oracle Cloud Native Environment software packages on each node.
  • Start the Oracle Cloud Native Environment platform services (Platform API Server and Platform Agent).
  • Create an Oracle Cloud Native Environment.
  • Create, validate and install a Kubernetes module, which creates the Kubernetes cluster.
  • Set up the Platform certificates to ~./olcne on the operator node to access the environment using the olcnectl command.

To create more complex installation topologies, you can write your own Oracle Cloud Native Environment configuration file and then pass it to the olcnectl provision command using the --config-file option. For more information, see the Platform Command-Line Interface Guide.

Objectives

This lab demonstrates how to:

  • Create a Virtual Cloud Network (VCN) to manage resources for hosting Oracle Cloud Native Environment on OCI.
  • Configure the VCN by setting up a public subnet, creating an internet gateway, making a route rule, and editing security list rules.
  • Provision OCI instances to serve as operator, control, and worker nodes for Oracle Cloud Native Environment.
  • Create and configure an external load balancer on OCI.
  • Set up a host with the Platform CLI (olcnectl) on the operator node.
  • Use the olcnectl provision command to perform a quick installation.
  • Install Oracle Cloud Native Environment Release 1.8 on a five-node cluster.
  • Verify the installation completed successfully.

Prerequisites

An OCI account and a compartment in OCI.
