3 likes802 views
The document provides an overview of Red Hat OpenShift, highlighting its need as a comprehensive Kubernetes distribution that addresses key operational components required for production environments. It discusses the functionalities of the OpenShift container platform, including developers' productivity tools, multi-cluster management, and integration with various services. Additionally, it details the role of Red Hat Enterprise Linux CoreOS and operators in managing containerized applications and virtual machines within the OpenShift ecosystem.
CNCF Meetup - OpenShift Overview
- 1. DRAFT OpenShift Overview Application Deployment on OpenShift Sumit Shatwara Solution Architect September 2020 1
- 2. Agenda 2 Agenda ● Why there was a need of new Kubernetes Distribution? ● Red Hat OpenShift Container Platform ● RHEL CoreOS ● Kubernetes Operators ● Red Hat OpenShift Virtualization ● Demo: Application Deployment on OpenShift ● Q&A
- 3. CNCF has 99+ Kubernetes distribution, and still why there was a need for open source community (led by Red Hat) to build one more? Kubernetes OpenShift Origin/OKD3 OKD4 (Red Hat OpenShift 3) (Red Hat OpenShift 4)
- 4. What’s needed to put Kubernetes into production? Enterprise Linux Cluster services monitoring, showback, registry, logging Application services middleware, functions, ISV Service mesh Developer services dev tools, automated builds, CI/CD, IDE Automated operations certified Lacks many essential components 1. Operating system 2. Container runtime (CRI-O, Containerd, Docker, etc). 3. Image registry 4. Software-defined networking 5. Load‐balancer and routing 6. Log management 7.

- 10. RHEL CoreOS : Immutable Operating System Based on upstream Fedora CoreOS - it is an automatically updating, minimal, container-focused operating system, monolithic, designed for clusters but also operable standalone, optimized for Kubernetes but also great without it. Red Hat Enterprise Linux CoreOS is managed by the cluster The Operating system is operated as part of the cluster, with the config for components managed by Machine Config Operator: ● CRI-O config ● Kubelet config ● Authorized registries ● SSH config v4.5.1 v4.5.1 RHEL CoreOS admins are responsible for: Nothing. Red Hat Enterprise Linux CoreOS is versioned with OpenShift CoreOS is tested and shipped in conjunction with the platform. Red Hat runs thousands of tests against these configurations.
