第 2 章 Architecture
Learn the specifics of Red Hat build of MicroShift architecture including design intent, how it differs from OpenShift Kubernetes Engine, and API compatibility.
2.1. Architectural design
MicroShift is a single-node container orchestration runtime designed to extend the benefits of using containers for running applications to low-resource edge environments. Because MicroShift is primarily a platform for deploying applications, only the APIs and features essential to operating in edge and small form factor computing environments are included.
For example, MicroShift contains only the following Kubernetes cluster capabilities:
- Networking
- Ingress
- Storage
- Helm
MicroShift also provides the following Kubernetes functions:
- Orchestration
- Security
To optimize your deployments, use MicroShift with a compatible operating system, such as Red Hat Enterprise Linux for Edge (RHEL for Edge). Using MicroShift and Red Hat Enterprise Linux for Edge (RHEL for Edge) together forms Red Hat Device Edge. Virtual machines are handled by the operating system in MicroShift deployments.
