Deploying OKD (Origin Kubernetes Distribution) on top of OpenStack creates a powerful, flexible private cloud environment ideal for both production workloads and development/test environments. This combination delivers scalable container orchestration, advanced automation, seamless lifecycle management, and strong cost efficiency.
What Are OKD and OpenStack?
OKD is the open-source upstream of Red Hat OpenShift, providing a full Kubernetes platform with integrated tools like CI/CD pipelines, RBAC, a web console, and automated upgrades.
OpenStack is an open-source cloud operating system that manages compute, networking, and storage. Kolla Ansible simplifies OpenStack deployment by containerizing its services.
Running OKD on OpenStack gives you a unified platform where your VMs and containerized apps coexist efficiently.
Benefits of Deploying OKD on OpenStack
1. Unified Cloud Environment for VMs and Containers
OKD runs on VMs provisioned by OpenStack, allowing organizations to run both legacy workloads (in VMs) and modern apps (in containers) on the same infrastructure.
2. Consistent Environments from Development to Production
With software-defined networks and compute resources, teams can replicate production environments for development or testing.
3. Enterprise-Grade Security and HA
OKD includes robust Kubernetes security features like OAuth, RBAC, and network policies. OpenStack enhances this with tenant isolation, security groups, and role-based access.
4. Image-Based Rollbacks and Lifecycle Management
OKD supports container image rollbacks and immutable node upgrades using CoreOS. VM images can be managed through Glance.
5. Flexible Testing and Development Environments
Using Kolla Ansible, you can deploy all-in-one OpenStack nodes and small OKD clusters on a single server for testing.
6. Autoscaling of Workloads and Infrastructure
OKD supports Kubernetes-native pod autoscaling. Worker nodes (VMs) can be added or removed dynamically using OpenShift's Machine API and Cluster Autoscaler.
7. Cost Efficiency and Open Source Flexibility
With no per-core or per-node licensing fees, OKD and OpenStack offer a low-cost alternative to public cloud and commercial Kubernetes solutions.
Why OKD on OpenStack Makes Sense for All Use Cases
- Production-Ready: Proven HA, security, and integration maturity.
- Developer-Friendly: Fast environment provisioning and easy rollback tools.
- Cost-Optimized: Zero license fees, hardware reusability, and autoscaling.
- Future-Proof: Open standards, vendor independence, and community support.
OKD on OpenStack is a robust, flexible, and cost-effective solution for modern cloud-native workloads. With features like dynamic autoscaling, secure multitenancy, and lifecycle automation, it provides the agility of Kubernetes with the control of a private cloud.
