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.

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.
- Simple to understand and contribute to
- Effortless to install, maintain, and operate
- Painless to troubleshoot
- Easy to configure via Service Mesh Interface (SMI)
Documentation pertaining to the usage of Open Service Mesh is made available at docs.openservicemesh.io.
Documentation pertaining to development, release workflows, and other repository specific documentation, can be found in the docs folder.
- 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
OSM is under active development and is ready for production workloads.

The simplest way of installing Open Service Mesh on a Kubernetes cluster is by using the osm CLI.
Download the osm binary from the Releases page. Unpack the osm binary and add it to $PATH to get started.
sudo mv ./osm /usr/local/bin/osm$ osm install
See the installation guide for more detailed options.
The OSM Bookstore demo is a step-by-step walkthrough of how to install a bookbuyer and bookstore apps, and configure connectivity between these using SMI.
After installing OSM, onboard a microservice application to the service mesh.
