As we have some integration test which is using the logger output to find out if the service center is started or not. So please don't change the service center started logger message (" Api server is ready" ).

i found i can not build the service-center binary from source code, first i encounter the flollowing errors:

then i replace all "golang.org/x/net/context" to "context" except code in vendor dir, then run go build -o service-center, but i still got many errors, such as:

i wonder how to build the binary from service center source code? thanks!

When I come to localhost:30100/health I Can see words like below:

{
  "instances": [
    {
      "instanceId": "d837ce4f950a11e78877a602b9b0d088",
      "serviceId": "d8159fcf950a11e78877a602b9b0d088",
      "endpoints": [
        "rest://127.0.0.1:30100"
      ],
      "hostName": "service_center_169_254_71_121",
      "status": "UP",
      "healthCheck": {
        "mode": "push",
        "interval": 30,
        "times": 3
      },
      "timestamp": "1504925946",
      "stage": "prod"
    }
  ]
}

I think that Maybe /health endpoint shows health info like below to make it compatible with spring boot actuator :

{
  "status": "UP"// the cluster status
}

And the current /health Maybe call /metadata .

What's more over, Is there any other status of service-center ? like :

UP
DOWN
OUT_OF_SERVICE
UNKNOWN

The refresh should only happen if the user is browsing that page

service center配置了使用证书的https访问后，frontend如何配置使用https证书模式？

The certificates stores under etc/ssl folder, while the application configuration files stores under conf folder, which looks inconsistent. Is it a better idea to merge both of it under etc folder?

Issue raised by @lexkong
my problem is, we have a api gateway, and now we want to find service from service center, which is from service center our api gateway can find host:port for the specified path such as: /calculator/bmi

is there any way or docs used to connect our api gateway and service center？

main.go 第40行：

addr := fmt.Sprintf("127.0.0.1:%d", *port)

修改为：

addr := fmt.Sprintf(":%d", *port)

假如我这边部署了两个service center（不知道能不能设置主从节点），用nginx作为反向代理，这样做会不会有问题？有必要这么做吗？

there are some translation mistakes need to correct, for example:

• ServiceComb -> 服务梳
• Version -> 版
• Operation -> 手术
• Application ID -> 应用程式编号

1. Is there any example to show how to use this feature with 3rd PACT library?
2. SC is producer too, and can it publish PACT automatic?
3. Does broker only support RESTful? how about the RPC like highway in java-chassis?

better to use CI to deliver latest, and release on-demand

How about to change the log module to logus or other opensource project?

百兆宽带版本1.0下载了N次下不来，能在华为官网挂个版本吗？

前提：华为公有云（ServiceStage）上已经部署好 ServiceCenter的容器应用，外部访问地址：117.78.49.144:30100， 内部访问地址192.168.0.244:30100，并且可以正常使用。

然后在华为公有云上部署 Frontend Servicecenter，结果失败：

   作为虚机应用部署; 启动参数：sh start.sh 停止参数：sh stop.sh
2. 失败信息

How can I get docker image for front end of service-center?

there are some typos such as recieve in design.md unkown in on.md.

some legacy system is running on VM, some of app is migrating to k8s , some are not. sc should give a way to support service discovery between legacy system and docker container platform

有提供web管理界面吗

我使用mac开发，发现没有对应的release，这给第一次使用的人带来很多不方便，可能很多人会因此放弃尝试

过程:
我发现没有mac的release后，使用docker版本启动了service-center，然后我打算启动frontend却发现没有docker版的frontend也没有mac的release, 无奈之下我自己编译service-center, 下载etc, 自己编译frontend, 拷贝配置，修改脚本，从打算实验service-center到跑起来整整浪费了1个小时的时间，如果mac版本完整，那应该就是几分钟的事情

安装 软件 Install Java development environment（软件安装方式） 和 Run Service Center（docker 方式运行） 有什么关系呢？
http://servicecomb.incubator.apache.org/docs/quick-start/

No README here, can anyone provide it?

正常关闭掉服务，日志也有提示取消注册成功，但是在注册中心看到该服务还是UP状态

如题，怎样平滑关闭Client？

https://github.com/ServiceComb/service-center/releases/download/0.1.0/service-center-0.1.0-windows-amd64.zip

Service-Center ZIP download is very slow (<1k average)

Is there a mirror site in China?

service name is case sensitive, but sc front end will rename the first letter to upper case. this is quit confusing.

@asifdxtreme , we should adjust the order according to the business logic.

service-center如何实现高可用和负载均衡

外面选择时端口是20879，实际测试时又是2087

( Error while sending request due to : Post http://10.63.185.117:2087/appServiceImpl2/queryApplicationFromInner: dial tcp 10.63.185.117:2087: connectex: No connection could be made because the target machine actively refused it.

若已经知道当前App里有哪些微服务后，能否通过调用API批量的注册这些微服务？
If I already know all microservices in the application, can I batch register them via API?

参考 codefirst 修改 resources\config\log4j.demo.properties 看起来是不行的。

代码位置：https://github.com/hank-whu/rpc-benchmark/tree/master/servicecomb-server

如标题

The default value of ssl_mode in configuration file app.conf is on, however, by default there has no certificates under the etc folder which makes the service-center refuse to start.

If the microservices count is more than 100 that limit the display of Topology view and give user option to select some particular AppId to view the topology

发现service centor中很多引用包的路径为：golang.org/x/net/context
但是service center中引用其他github的包中引用的路径是“context”这样会导致冲突，
这个当时你们是怎么考虑的呢，怎么解决的呢

hi:
昨天下了service-center的docker镜像，跑起来之后，访问：http://localhost:30100、提示Invalid Request URI，麻烦大神帮忙解答。

service-center有没有监控的UI页面？ 查看微服务列表等。

Like where is API doc, how to run image, it is lacking of document

https://hub.docker.com/r/servicecomb/service-center/

1. Download service-center-0.4.0-linux-amd64.tar.gz
2. Execute start.sh
3. Send CTRL+C after SC is ready
4. Execute start.sh again
   And SC hung for some reasons.

是否支持 使用自签证书 etcd server （开启ssl client verify）?
