Container Engine for Kubernetes

Oracle Cloud Infrastructure Container Engine for Kubernetes (OKE) is a managed Kubernetes service that simplifies the operations of enterprise-grade Kubernetes at scale. It reduces the time, cost, and effort needed to manage the complexities of the Kubernetes infrastructure. Container Engine for Kubernetes lets you deploy Kubernetes clusters and ensure reliable operations for both the control plane and the worker nodes with automatic scaling, upgrades, and security patching. Additionally, OKE provides a fully serverless Kubernetes experience with virtual nodes.

OKE features

Operations

Managed nodes

Managed nodes are worker nodes that are provisioned within a customer's tenancy and operated and configured by the customer. Managed nodes are suitable for customers who need worker nodes that require compute shapes not supported by virtual nodes or more significant control and customized configuration for their worker nodes.

Serverless Kubernetes with virtual nodes

Virtual nodes provide a serverless Kubernetes experience to run containerized applications at scale without spending additional resources on managing, scaling, upgrading, and troubleshooting the infrastructure of your clusters.

Virtual nodes provide the abstraction of regular nodes to Kubernetes, delivering granular pod elasticity with per-pod pricing. You can scale your deployments without taking into consideration the cluster's capacity, simplifying the execution of scalable workloads, such as high-traffic web applications and data-processing jobs.

Automatic Kubernetes upgrades

Trigger an upgrade of your Kubernetes version with one click. Virtual nodes automatically deliver seamless, on-the-fly updates and security patches of your worker nodes and underlying infrastructure, while respecting the availability of your applications.

Highly available Kubernetes with autoscaling

Increase the availability of applications using clusters that span multiple availability domains (data centers) in any commercial region or in Oracle Cloud Infrastructure (OCI) Dedicated Region. Scale pods horizontally and vertically and scale clusters too.

Add-ons Lifecycle management

You can easily expand and control the functionality of your Kubernetes cluster with a curated collection of configurable add-on software that is fully managed by OCI. This software includes a growing portfolio of operational software deployed on your cluster as well related apps and operators, including CNI, CoreDNS, Kubernetes Dashboard, Oracle Database Operator, WebLogic operator, and more.

OKE manages the lifecycle for the add-on software—from the initial deployment and configuration through ongoing operations, such as upgrades, patching, scaling, rolling configuration changes, and more.

Users can select add-ons and customize configurations during the cluster creation, including disabling specific add-ons, specifying the add-on version, and opting out of automatic updates or of certain OCI-provided add-ons to use their own software.

Cluster observability

Monitor and secure these applications with tools from Oracle Cloud Infrastructure, Datadog, Aqua Security, and other partners.

Self-healing cluster nodes

When it detects node failures, Container Engine for Kubernetes automatically provisions new worker nodes to maintain cluster availability.

Safe node delete

Safely delete your worker nodes without disrupting your applications with automated cordon and drain options.

Financially backed SLA

The service level agreement (SLA) included with OKE clusters provides financial support for the uptime and availability of the OKE control plane and worker nodes. The coverage for the worker nodes is equivalent to what the OCI Compute SLA provides.

Made for developers

One-click cluster creation

Deploy Kubernetes clusters, including the underlying virtual cloud networks, internet gateways, and NAT gateways, with a single click.

Complete REST API and command line interface (CLI) support

Automate Kubernetes operations with web-based REST API and CLI for all actions, including Kubernetes cluster creation, scaling, and operations.

A comprehensive range of compute options

Optimize cost and performance by choosing the most appropriate compute shapes from a wide range of bare metal, high-performance computing (HPC), and virtual machine options. Manage GPU and Arm-based applications in a Kubernetes environment with OKE. Support multiarchitecture images with Oracle Container Image Registry.

Tight integration with other OCI services

Container Engine for Kubernetes easily integrates with Oracle Cloud Infrastructure services, such as OCI Container Registry, DevOps CI/CD, networking, storage, and more. OCI Service Operator for Kubernetes enables you to manage your OCI services directly from your OKE cluster.

Built on open source, works with your DevOps toolchain

Container Engine for Kubernetes is built on open standards and is fully conformant with open source upstream Kubernetes. This enables you to leverage ecosystem solutions and easily integrate with your dev tools, such as Argo CD, Gitlab, Jenkins, and others.


Security

Encryption

Encrypt Kubernetes secrets at-rest using the Key Management service.

Oracle always encrypts block volumes, boot volumes, and volume backups at rest using the Advanced Encryption Standard (AES) algorithm with 256-bit encryption. You can also manage the lifecycle of your own encryption keys using Oracle Cloud Infrastructure Vault.

Compliance

OCI Container Engine for Kubernetes complies with regulatory frameworks, such as HIPAA, PCI, and SOC 2.

Private Kubernetes clusters and Bastion

With private clusters, you can restrict access to the Kubernetes API endpoint to your on-premises network or a Bastion host, improving your security posture. To easily access fully private clusters, you can now use Oracle Cloud Infrastructure (OCI) Bastion.

Strong isolation at the pod level

Virtual nodes provide strong isolation to each Kubernetes pod. Pods do not share any underlying kernel, memory, or CPU resources. This pod-level isolation enables you to run untrusted workloads, multitenant applications, and sensitive data.

Network security groups for your Kubernetes clusters

Container Engine for Kubernetes supports network security groups (NSGs) for all cluster components. An NSG consists of a set of ingress and egress security rules that apply to virtual network interface cards (VNICs) in your virtual cloud network (VCN). With NSG, you can separate your virtual cloud network architecture from your cluster components’ security requirements.

Authentication and authorization

Control access and permissions using native OCI Identity and Access Management (IAM), Oracle Identity Cloud Service, and Kubernetes role-based access control. You can also configure OCI IAM multifactor authentication.

Workload Identity enables you to establish secure authentication at the pod level for OCI APIs and services. By implementing the principle of “least privilege” for your workloads, you can ensure users only have access to necessary resources. This enhances your security posture by minimizing the potential of security breaches or unauthorized access.

Container image scanning, signing, and verification

OKE supports container image scanning, signing, and verification so you can ensure that your application images are free of serious security vulnerabilities and that the integrity of the container images is preserved when deployed by enforcing image signing.

Audit the Kubernetes activity

All Kubernetes audit events are made available in the OCI Audit service.

Flexibility and performance

Build apps that work across on-premises and other clouds

Container Engine for Kubernetes uses unmodified open source Kubernetes that complies with the Cloud Native Computing Foundation (CNCF) and Open Container Initiative (OCI) standards for application portability.

Flexibility to use any tool for cluster management

Bring your own tools, or take advantage of Oracle's partners for security, federation, observability, and build automation.

End-to-end container lifecycle management
