Mesher

A service mesh implementation based on go chassis.

Why use mesher

• any infrastructure: if you use ServiceComb as control plane, you can run on any infrastructure(docker, kubernetes,VM, bare metal).
• service mesh and frameworks:
  you can develop micro services with java chassis or go chassis frameworks
  and use mesher to make other service join to the same system.
• flexible: you can develop and customize your own service mesh
• OS: support both linux and windows OS, which means you can govern your services writen in .net with java, go etc.
• API gateway: mesher is able to run as a independent edge service and manage ingress traffic.

Features

• Build on top of go micro service framework: so that mesher has all of features of
  go chassis,a high flexible go micro service framework.
  you can custom your own service mesh and API gateway by extending lots of components.
• Admin API：Listen on an isolated port, expose useful runtime information and metrics.
• support protocols: http and grpc
• No IP tables forwarding: Mesher leverage
  http_proxy
  and grpc proxy dialer,
  that makes better performance than using ip tables
• local health check: as a sidecar, mesher is able to check local service health by policy
  and dynamically remove it from service registry if service is unavailable.

export GOPATH=/path/to/gopath
export GOPROXY=https://goproxy.io #if you are facing network issue
./build_proxy.sh

it will build binary and docker image

RoadMap

1.7.0

• mesher ingress: mesher as a edge service to manage ingress traffic
• integrate with servicecomb kie: user can change mesher-sidecar and mesher-ingress in same config server, don't need to change local files

in future

• support skywalking
