It is in charge of all things about implementation of Service Mesh.

What are our tasks?

1. Retrieving the data of service & instances from a registry center such as Nacos, zookeeper.
2. Generating the istio's CRD through various data such as registry data & configurations.
3. Make MOSN be able to support serve a registry request which comes from a dubbo provider.

Installing and running

Build

Direct compilation:

$ make manager

Build docker image and push:

$ make docker-build
$ make docker-push

You can customize the docker repository by modifying the IMG_ADDR variable in the Makefile.

Deploy

Install CRD:

$ make install

Install CRD no validations:

$ kubectl apply -f config/crd/simple

Create sample Meshconfig and default Sidecar:

$ kubectl apply -f config/samples/mesh_v1alpha1_meshconfig.yaml -f config/samples/istio_default_sidecar.yaml

Deploy adapter and controller:

$ make deploy

You can customize the deployment by modifying the config/operator and config/adapter kustomize config files.
