Apache ServiceComb Service-Center is a Restful based service-registry that provides micro-services discovery and micro-service management. It is based on Open API format and provides features like service-discovery, fault-tolerance, dynamic routing, notify subscription and scalable by design. It has high performance cache design and separate entity management for micro-services and their instances. It provides out of box support for metrics and tracing. It has a web portal to manage the micro-services.
- server: a http server which provide restful API
- scctl: CLI of server
- syncer: alpha feature. multiple cluster synchronization tool, designed for large microservice architectures
Open API: API doc(Open API format) management for microservice- Metadata: Metadata management for both microservice and microservice instance
- Separated: Separated microservice and microservice instance entity management
- Domains: Logical multiple domains management
- Security: White and black list configuration for service discovery
- Discovery: Support query instance by criteria
- Subscribe: Use web socket to notify client about instance change events
Portal: Awesome web portal- Fault tolerance: Multiple fault tolerance mechanism and design in the architecture
- Performance: Performance/Caching design
Metrics: Able to expose Prometheus metric API automatically, seeTracing: Able to report tracing data to Zipkin serverPluginable: Able to load custom authentication, tls and other dynamic librariesCLI: Easy to control service centerKubernetes: Embrace kubernetes ecosystem and support multi cluster service discoveryDatacenters: Additional layer of abstraction to clusters deployed in multiple datacentersAggregation: Able to aggregate microservices from multiple registry platforms and support platform registry and client side registry at the same time
Project documentation is available on the ServiceComb website. You can also find full document here.
The easiest way to get Service Center is to use one of the pre-built release binaries which are available for Linux, Windows and Docker.
You can download our latest release from ServiceComb Website.When you get these release, you can execute the start script to run Service Center.
Windows(apache-servicecomb-service-center-XXX-windows-amd64.zip):
start-service-center.bat
Linux(apache-servicecomb-service-center-XXXX-linux-amd64.tar.gz):
./start-service-center.shDocker:
docker pull servicecomb/service-center
docker run -d -p 30100:30100 servicecomb/service-centerNote: The Releases of Service-Center uses emebeded etcd, if you want to use the seperate instance of etcd then you can deploy the etcd seperately and configure the etcd ip over here.
vi conf/app.conf
## Edit this file
# registry address
# 1. if registry_plugin equals to 'embeded_etcd'
# manager_name = "sc-0"
# manager_addr = "http://127.0.0.1:2380"
# manager_cluster = "sc-0=http://127.0.0.1:2380"
# 2. if registry_plugin equals to 'etcd'
# manager_cluster = "127.0.0.1:2379"
manager_cluster = "127.0.0.1:2379"
By default the SC comes up on 127.0.0.1:30100, however you can change the configuration of these address over here.
vi conf/app.conf
httpaddr = 127.0.0.1
httpport = 30100
Requirements
- Go version 1.9+ is required to build the latest version of Service-Center.
Download the Code
git clone https://github.com/apache/servicecomb-service-center.git $GOPATH/src/github.com/apache/servicecomb-service-center
cd $GOPATH/src/github.com/apache/servicecomb-service-centerDependencies
you can download dependencies directly using command go mod. Please follow below steps to
download all the dependency.
# skip the checksum verifying if you use the private proxy
export GOSUMDB=off
# Download the modules
GO111MODULE=on go mod download
GO111MODULE=on go mod vendorBuild the Service-Center
go build -o service-center github.com/apache/servicecomb-service-center/cmd/scserverFirst, you need to run a etcd(version: 3.x) as a database service and then modify the etcd IP and port in the Service Center configuration file (./etc/conf/app.conf : manager_cluster).
wget https://github.com/coreos/etcd/releases/download/v3.1.8/etcd-v3.1.8-linux-amd64.tar.gz
tar -xvf etcd-v3.1.8-linux-amd64.tar.gz
cd etcd-v3.1.8-linux-amd64
./etcd
cd servicecomb-service-center
cp -r ./etc/conf .
./service-centerThis will bring up Service Center listening on ip/port 127.0.0.1:30100 for service communication.If you want to change the listening ip/port, you can modify it in the Service Center configuration file (./conf/app.conf : httpaddr,httpport).
sudo bash scripts/docker/build-image/build.shit builds a image servicecomb/service-center
You can download our latest release from ServiceComb Website and then untar it and run start-frontend.sh/start-frontend.bat. This will bring up the Service-Center UI on http://127.0.0.1:30103.
Windows(apache-servicecomb-service-center-XXX-windows-amd64.zip):
start-frontend.bat
Linux(apache-servicecomb-service-center-XXXX-linux-amd64.tar.gz):
./start-frontend.shNote: By default frontend runs on 127.0.0.1, if you want to change this then you can change it in conf/app.conf.
frontend_host_ip=127.0.0.1
frontend_host_port=30103
You can follow the guide over here to run the Frontend from source.
