OpenShift
open source container application platform
About OpenShift
Build for the future. Start today.
Traditional and cloud-native. On-premises and in the cloud. No matter what you build, Red Hat® OpenShift® is the leading Kubernetes platform for delivering the extraordinary to your users, faster than you can imagine.
- Ship faster
- Deploy anywhere
- Operate with confidence
OpenShift Topics
The following are the things covered under OpenShift.
OpenShift - Architecture
OpenShift is a layered system wherein each layer is tightly bound with the other layer using Kubernetes and Docker cluster.
OpenShift - Build Automation
In OpenShift, we have multiple methods of automating the build pipeline. In order to do that we need to create a BuildConfig resource to describe the build flow.
OpenShift - CLI Operations
OpenShift CLI is capable of performing all basic and advance configuration, management, addition, and deployment of applications.
OpenShift - Application Scaling
Autoscaling is a feature in OpenShift where the applications deployned can scale and sink as and when requierd as per certain specifications.
OpenShift - Docker and Kubernetes
OpenShift is built on top of Docker and Kubernetes. All the containers are built on top of Docker cluster, which is basically Kubernetes service on top of Linux machines, using Kubernetes orchestrations feature.
OpenShift - Security
OpenShift security is mainly a combination of two components that mainly handles security constraints - SCC and SA
