Installation
This section describes how to install/uninstall Open Service Mesh (OSM) on a Kubernetes cluster
Getting Started
Open Service Mesh (OSM) is a lightweight, extensible, Cloud Native service mesh that allows users to uniformly manage, secure, and get out-of-the-box observability features for highly dynamic microservice environments.
The OSM project builds on the ideas and implementations of many cloud native ecosystem projects including Linkerd, Istio, Consul, Envoy, Kuma, Helm, and the SMI specification.
Overview
OSM runs an Envoy based control plane on Kubernetes, can be configured with SMI APIs, and works by injecting an Envoy proxy as a sidecar container next to each instance of your application. The proxy contains and executes rules around access control policies, implements routing configuration, and captures metrics. The control plane continually configures proxies to ensure policies and routing rules are up to date and ensures proxies are healthy.
Core Principles
- Simple to understand and contribute to
- Effortless to install, maintain, and operate
- Painless to troubleshoot
- Easy to configure via Service Mesh Interface (SMI)
Features
- Easily and transparently configure traffic shifting for deployments
- Secure service to service communication by enabling mTLS
- Define and execute fine grained access control policies for services
- Observability and insights into application metrics for debugging and monitoring services
- Integrate with external certificate management services/solutions with a pluggable interface
- Onboard applications onto the mesh by enabling automatic sidecar injection of Envoy proxy
Project Status
OSM is under active development and is NOT ready for production workloads.
