Deploy Oracle Cloud Native Environment

Learn how to install and configure Oracle Cloud Native Environment on Oracle Linux.

Oracle Cloud Native Environment is a fully integrated suite for the development and management of cloud native applications. The Kubernetes module is the core module. It is used to deploy and manage containers and also automatically installs and configures CRI-O, runC and Kata Containers. CRI-O manages the container runtime for a Kubernetes cluster. The runtime may be either runC or Kata Containers.

Use Gluster with Oracle Cloud Native Environment

Learn how to set up and use Gluster with Oracle Cloud Native Environment.

The Gluster Container Storage Interface module can be used to set up statically or dynamically provisioned persistent storage for Kubernetes applications using Gluster Storage for Oracle Linux in Oracle Cloud Native Environment. In this example, we will create an integrated system where Kubernetes worker nodes provide persistent storage using Gluster on Oracle Cloud Native Environment.

Run a Compact Oracle Cloud Native Environment

Learn how to install and configure a compact deployment of Oracle Cloud Native Environment on Oracle Linux.

The 1.5 release of Oracle Cloud Native Environment introduced the compact deployment, allowing non-system Kubernetes workloads to run on control plane nodes. When setting –compact to true, the Platform API Server does not taint the control plane node(s). This setting allows non-system Kubernetes workloads to be scheduled and run on control plane nodes.

Use OCI Cloud Controller Manager on Oracle Cloud Native Environment

Learn how to enable the Load balancer Service type in Oracle Cloud Native Environment on Oracle Cloud Infrastructure.

The Kubernetes LoadBalancer Service exposes the Deployment externally using a cloud provider’s load balancer. The dependent NodePort and ClusterIP Services, to which the external load balancer routes, are automatically created.

This tutorial shows how to deploy the Oracle Cloud Infrastructure Cloud Controller Manager module (OCI-CCM module) within Oracle Cloud Native Environment to handle requests for an external LoadBalancer Service type. The Oracle Cloud Infrastructure Cloud Controller Manager module uses the open source oci-cloud-controller-manager project, which is a Kubernetes Cloud Controller Manager implementation (or out-of-tree cloud-provider) for Oracle Cloud Infrastructure (OCI).

Use MetalLB with Oracle Cloud Native Environment

Learn how to install and configure MetalLB together with Oracle Cloud Native Environment on Oracle Linux.

Network load balancers provide a method of externally exposing Kubernetes applications. A Kubernetes LoadBalancer service is used to create a network load balancer that provides and exposes an external IP address that can be used to connect to an application from outside the cluster.

MetalLB is a network load balancer for Kubernetes applications deployed on Oracle Cloud Native Environment running on bare metal hosts. MetalLB allows you to use Kubernetes LoadBalancer services, which traditionally make use of a cloud provider network load balancer, in a bare metal environment.

Scale a Kubernetes Cluster on Oracle Cloud Native Environment

Learn how to scale a Kubernetes Cluster on Oracle Cloud Native Environment.

This tutorial demonstrates how to scale an existing Kubernetes cluster in Oracle Cloud Native Environment.

To scale up a Kubernetes cluster means adding nodes, likewise scale down occurs by removing nodes. Nodes can be either control plane or worker nodes. Oracle recommends against scaling the cluster up and down at the same time. Instead perform a scale up, then scale down, in two separate commands.

This tutorial uses an existing Highly Available Kubernetes cluster running on Oracle Cloud Native Environment, and has three modules deployed:

• Kubernetes (kubernetes)
• Helm (helm)
• Oracle Cloud Infrastructure Cloud Controller Manager Module (oci-ccm)

Use Quick Install to Deploy Oracle Cloud Native Environment

Learn how to use Quick Install to install and configure Oracle Cloud Native Environment on Oracle Linux.

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. This is done using the olcnectl provision command on an installation host (the operator node).

This lab describes how to perform a quick installation using the simplest series of steps possible to get Oracle Cloud Native Environment and a Kubernetes cluster installed. This lab uses private CA Certificates. It is recommended for a production environment that you use your own CA Certificates.

Provision Persistent Volumes Using File Storage Service on Oracle Cloud Native Environment

Learn how to provision Persistent Volumes using File Storage service on Oracle Cloud Native Environment on Oracle Linux.

Oracle Cloud Native Environment ships with the ability to install the Oracle Cloud Infrastructure (OCI) Cloud Controller Manager (CCM). The CCM is OCI’s implementation of the Kubernetes control plane component that links your Kubernetes cluster to OCI. The OCI CCM project implements a Container Storage Interface (CSI) plugin for Kubernetes clusters that implements both OCI Block Volume Storage and OCI File Storage Service to store persistent data.

This lab will focus on OCI File System service to provide nfs-style cloud storage.

Use Persistent Volumes and Persistent Volume Claims with Oracle Cloud Native Environment

This tutorial shows how to create and use Persistent Volumes and Persistent Volume Claims with Oracle Cloud Native Environment. Both Persistent Volumes and Persistent Volume Claims work together to provide persistence to any container-based applications deployed onto Oracle Cloud Native Environment. You will start by covering how to use Persistent Volumes initially, and then cover the use of Persistent Volume Claims.

Upgrade to Oracle Cloud Native Environment 1.6

Learn how to upgrade to Oracle Cloud Native Environment 1.6.

Administrators of an Oracle Cloud Native Environment deployment are aware that many of the components, such as Kubernetes, are regularly updated. The upgrade process updates these components to the most recent release allowing any new features to become available for users.

This tutorial will show how to upgrade an Oracle Cloud Native Environment Release 1.5 install to Release 1.6.

Run KubeVirt on Oracle Cloud Native Environment

Learn how to deploy and run KubeVirt on Oracle Cloud Native Environment.

KubeVirt is a virtualization technology to create and manage virtual machines in Kubernetes. Administrators create these virtual machines using the kubectl command and Kubernetes custom resource definitions (CRDs). As with any container image within Kubernetes, it requires persistent storage to maintain its state. Hence, our need for Rook and Ceph.

Rook is a cloud-native storage orchestrator platform that enables Ceph storage for our Kubernetes cluster. Rook deploys as a Kubernetes operator inside a Kubernetes cluster and automates the tasks to provision and de-provision Ceph-backed persistent storage using the Kubernetes Container Storage Interface (CSI).

While Ceph allows the creation of block and object storage, there also exists a shared file system storage. This type uses a CephFilesystem (CephFS) to mount a shared POSIX (Portable Operating System Interface) compliant folder into one or more pods. This storage type is similar to NFS (Network File System) shared storage or CIFS (Common Internet File System) shared folders.

This tutorial guides users on deploying KubeVirt with Ceph storage managed by Rook on Oracle Cloud Native Environment.
